Ham Shack Major Upgrade

This is my little corner of the world. The new desk is almost finished. Key features:
  1. about 7ft wide, 30" deep and 7ft high
  2. 3 drawers on the left, room for 2 computers plus paraphernalia (UPS, ethernet switch, etc) on the right--I will add the second computer after I install AndysHamV21 on it
  3. ~18" adjustable shelves on each side
  4. top shelf holding misc items
  5. middle shelf for stability and storage--and ultimately my on air sign 
  6. 200mm computer case fan to cool the HF rig (Ten Tec Jupiter)
  7. small, fixed shelf on the right to hold the 2M rig and power supply
  8. my DIY 12V power strip (for the fan and sign)
  9. pull-out keyboard shelf and pull out work/writing area
  10. 8-outlet power strip (behid the monitors and radio)
  11. 26" Samsung TV/monitor connected via HDMI cable
  12. 21"  monitor connected via VGA cable through a KVM switch to both computers to facilitate sharing
  13. pre-existing telephone jack now comes in through a wall plate in the desk side
  14. 2" holes in several locations for wire management
  15. notches in each of the 18" shelves to accommodate wires and cables
It took the equivalent of 4 4'x8' sheets of 3/4" plywood, plus some 2x4s for framing, some 1"x4" pine for trim, and some 1/2" plywood for the keyboard shelf. I put on 2 coats of stain plus 2 coats of polyurethane (8 coats on the desktop). We  used drawer slides from Rockler for the drawers and the pullouts

We also took the time to run the coax from the 2M and HF antennae across the ceiling and behind the wall. The desk is where the coax came into the shack anyway--it's just neater now, coming in through a wall plate and on to the radios,. We also ran the ethernet cables behind the walls. There had been cables all over the place. Now the ethernet runs:
  • from the cable modem/wireless router into the wall across the ceiling to a dual wall plate
  • from the dual wall plate an ethernet switch
  • from the switch to the XYL's computer and another cable from the switch back into the wall plate
  • from the wall plate across the ceiling to another wall plate under the desk
  • from the wall plate to another switch that feeds each computer
Dual ethernet wall plate--cable comes from the cable modem/wireless router and into switch. One output from the switch goes to the XYL's desktop--the other goes back to the wall plate and on to the shack

I'm in heaven.  All credit goes to my brother-in law (the one with the skills). .This is a substantial piece of furniture. I can't get a clear shot to take a photo of the whole thing--it's too big. I still have a little work to do, but it's great!

12V DC Power Strip

Assembled and tested, ready for use

I have been busy with some projects lately, and have not been active on the blog. This effort is a small part of my desk project that will be on the blog soon (give or take...).  The desk will accommodate (among other things) my amateur radio equipment.  Amateur radio stuff generally runs off ~12V DC (actually closer to 13.8). There are DC power strips available commercially, but because they handle 30 Amps or more and are intended to be fed by a power supply designed for a radio, they are expensive. I just want to power a fan that cools the radio and a station "on air" sign, so I don't need that.

So, I got a Harbor Freight givaway 110VAC power strip, and took it apart.

I cut off the power cord (it will make an extension cord someday), removed the safety ground copper strip, and drilled out the slots for the prongs of AC plugs to accommodate DC binding posts.
Strip with holes drilled, and some posts installed. Note the mod to the red post on the right.
I cut off the threaded bottom parts to leave just the post (see photo).  Then I soldered the bare binding posts to the copper strips on the positive and negative rails, and screwed bottom back on.
Next I needed a 12V supply. I bought an old wall wart for US$2 at a "Hamfest" (that's basically a flea market for amateur radio people, although there can be some high priced stuff there). Since the jack on the wall wart was not standard, I cut it off and just soldered the wires to the wires to the power strip. It will handle 1250mA, which should be sufficient. As shown in the first photo, it worked. Next step: plug the 200mm computer case fan into the power strip.

Fan plugged into power strip
I'll add the On Air sign after Santa Claus brings it.

Preview of the desk. The blue light to the right of the monitor and behind the radio is the fan--it has 4 blues LEDs, powered by the wall wart through the power strip. My old desk is on the left. It will be removed soon.
I've been using the desk, although we have a couple of additions to make.  We'll add a slide-out drawer for the keyboard and mouse, and a pull-out work surface on the right, over the computers. We also have some trim to add. When I say "we" I mean my brother-in-law--the one with the skills--under my "supervision."

First 80M Contact--and I don't have an 80M antenna

My antenna is a G5RVjr--supposedly good on 10-40meters.  I use it on 20 and 40--I have had no success on other bands.

This week I'm chasing the Route 66 stations (see here), and I'm down to the last 3 out of 21.  Last night I was watching the spots for those 3.  One I couldn't hear, one couldn't hear me, and the other was on 80.  Just for grins, I went to see if I could hear it. I couldn't, but I did hear several other stations very clearly.  So, today I decided to see if I could transmit.  During the day I heard nothing.  Tonight there were no spots for Route 66 stations, but the New Jersey QSO Party was going on.  The first one I tried could not hear me, but another gave me a 59 signal report. First 80 meter QSO!

I have heard that it is possible to tune a 40m antenna for 80m but this is the first time I tried it.

Ambivalence re FT8

17:09 UTC today marked exactly one week of FT8 usage. For the 7 months preceding that, I had been focusing on JT9/JT65, and was amazed at how rapidly I was building up my list of contacts--640, at least 63 countries. FT8 puts that to shame: in ONE WEEK I had  312 QSOs with 29 countries. I worked 9 stations in my first 45 minutes using the mode.

FT8 is really addictive--it's hard to step away from--the instant response is great reinforcement.  I went back to JT65 the other day and found it WAY too slow. The difference is that you have to stay with FT8--on JT65 you can set it up and go do other work on the computer until you get an alert, then go back and jump in.

Right now, I love FT8.  It's a great way to build up contacts and fill in gaps for awards--as well as to communicate with the world (tiny messages notwithstanding). One negative I see now is that I expect to burn out on it--I can feel that starting to happen already. We'll see--the up side is that I've been motivated to go back to SSB at times--I've been in some contests, and I was able to work an Oklahoma station, which was the last state I needed for WAS Phone (now if I can just get 8 stations to return QSL cards...).

There is a philosophical discussion around whether FT8 is a real mode that should count for awards and such.   As a relatively new ham with no Morse Code nostalgia, I believe that there should be no distinction.  There are categories within the awards for various modes and bands, and those should satisfy the curmudgeons.  Amateur Radio has always been about  continuous improvement and use of new technology. To disparage people who do that is to disparage the service in an attempt to define a "real ham" in the image of one's own experience.

On the other hand, FT8 will take some getting used to.  It's different.  It's also fun and useful.

More on Worked All States Plus CQ WPX

In my last post on this subject, I mentioned that I just needed Maine for several endorsements. Well. I finally got Maine on FT8 on 40M, giving me WAS Digital.  I am still at 49, lacking Maine,  for WAS 20M and JT65.

Also, I made SSB contact with an Oklahoma station the other night, giving me WAS Phone, although I an awaiting 8 QSL cards for documentation. So, that's WAS Mixed, Digital, and Phone,

Meanwhile, I discovered the CQ WPX award, which counts prefixes. I qualify for WPX Mixed (400 contacts) ans WPX Digital (300) plus 20M and North America endorsements for both.  I was going to apply but LOTW wanted $56+ on top of the $12 CQ Magazine would charge for each.  I'll be happy with the accomplishment and forego the fancy certificates.

Fourth of July Lights

With my grandchildren coming for the Fourth of July, I went looking for projects to do. This is one, thanks to John Wargo--original and Fourth of July Version.

I made slight modifications to the Fourth of July version, using a Trinket instead of the Pro Trinket, because I had some of the smaller ones inventory. I also decided to leave off the LiPo charging backpack,  used a pushbutton switch, and used perf board for tidiness.

I used John Wargo's code almost exactly. The only difference is that he used pins 9, 10, and 11 but the Trinket does not have those pins.  Only pins 0, 1, and 4 on the Trinket handle PWM, so I replaced the array provided in the code "int ledPins[] = { 9, 10, 11 };" with "int ledPins[] = { 0, 1, 4 };".

Fritzing Diagram of Circuit


Parts (references to Radio Shack are good as of writing--no guarantee how long they will last)
  • Adafruit Trinket 3V
  • pushbutton switch (example--any SPST switch will do)
  • Radio Shack Dual Proto Board (or any perf board)
  • Wire Light LED Strands (1 each red, white, and blue)
  • 47 Ohm Resistors (3)
  • JST-PH Breakout Board
  • 1 Quart Ball Mason Jar (any jar with a lid will do--this size works well)
  • Wire Light LED Strands: Red, White, and Blue (note that these are NOT what's shown in the Fritzing diagram--I used the closest image they had in the parts bin).
  • 47 Ohm Resistors (3, one for each LED strand): see Adafruit descriptions of the lights, above--no resistor is needed with coin cells, but " If you want to use a 4.5V power supply, use 20-220 ohms (or larger)"--so I chose 47 for the 3,3V Trinket (having noticed how much brighter the LEDs were off the Trinket vs. off the CR2032s with no current-limiting resistor).
  • Tinned copper bus wire  and hookup wire-- like this, for example--depending on distances and how much insulation you need
  • Gaffer Tape
  • 500 mAh LiPo battery
  • JST-RCY cable Note:  the battery I used (see link above) has a JST-RCY connector and the JST breakout board has a JST-PH connector, I needed this cable and the next to use it. If yours has a different connector, you may not need these at all,  or you may need something instead of the -RCY cable. The 100mAh version shown in the Fritzing diagram, and most (or all) of Adafruit's LiPos, have JST-PH connectors, making all this unnecessary. I could have just cut the -RCY connector off and spliced on the -PH cable, but that was too permanent for me...and now I have a useful -RCY to -PH adapter.
  • JST-PH 2-pin Cable
  • Drill (I used my drill press--you just need a way to drill holes)
  • Step Bit (I needed ~16mm for my switch--different switches will have different requirements)
  • Wire tools: strippers, flush cutters, etc.
  • Normal soldering equipment: iron, sucker, helping hands, etc.

The bulk of the time was spent in design--mostly how to fit everything where I wanted.  The mason jar lid cramped my style. Even thought the Trinket is small, it took some maneuvering to get the perf board, theTrinket, and the JST breakout next to the whole I drilled.
  1. I laid out the space requirements on the inside of the lid, then cut the perf board to size and experimented with positioning until I was no unhappy
  2. I drilled the hole in the lid for the switch
  3. I made the RCY to PH JST cable to connect the battery: I just soldered the 2 together and heat shrinked
  4. The LED strands referenced above come with coin cell battery holders. I needed to cut the leads from the battery holders to use them, taking care to note which lead is positive (mine had white markings on the + lead, but I tested it to be sure and marked each with red and black Sharpies).
  5. Wire it up
  6. Test and correct as necessary.
  7. Solder.
    I used tinned copper bus wire to make a ground bus down one side of the perf board, fed by the negative pin on the JST-PH breakout.
    To that, I soldered the GND pin on the Trinket and the negative leads of all 3 LED strands.
    I soldered one resistor to each positive LED lead and heat shrinked it for insulation, then soldered the other leads of the resistors to the proper Trinket pins. 
  8. I used gaffer tape to secure the circuit to the lid and the battery to the jar

Worked All States!!

I did it! Yesterday afternoon I had a JT65 QSO with a station in Hawaii. When I checked my Logbook of the World account this morning, it was confirmed.  That completes my 50 states (mixed). I have other Worked All States (WAS) awards to pursue, but I'm really happy to have this completed.

Twenty Meters was great yesterday--I made this contact with Hawaii before I repaired my antenna (one of my side of my G5RV Jr. had broken loose from the cord that ran from the dogbone to a tree...later yesterday with help from another ham I inserted a bungee cord, re-tied the cord, and raised and tightened the antenna).

Vintage Clock Radio Teardown

Yesterday my wife presented me with a 1966 Sears Silvertone Clock radio, model 6048.  The clock turned on but the radio did not.  I opened the case to find it was a vacuum tube device, so before I tore it down I took it a meeting of one of my amateur radio clubs, which happened to be last night, to see if anyone wanted to play with it. There was some curiosity, but no takers, so I tore it down.
Case open, pre teardown
Torn down
Salvaged Parts
After all that, I wound up with pretty much what I expected: a speaker, some knobs, 2 POTs, and some screws.  I also kept the transformer for the speaker--cursory research reveals that a permanent magnet speaker may need a transformer. I do not know if that's a function of the radio or the speaker--but I will try to find out.  I also kept the internal antenna, just for grins.

So, a piece of history bites the dust, but hopefully I will have some use for the parts.

Head Move Donkey V02: progress

After this post on my donkey update I learned some things, much of it from Adafruit Support on the forum in this thread.

First I was concerned with a statement in the MusicMaker Learning Guide "Don't forget to make sure you have a good strong 5V power supply - especially if you're using the 3W 4 ohm speakers! " It turns out that I was able to do what I needed with the 3.7V LiPo--I noticed no difference in output using the 5V 2A  wall wart.  I was even able to run everything off the 4xAA battery pack (using NiMHs only give 1.2V each, 4.8V total).  However, when I added the second Servo. I needed 2 power supplies.

Second I had trouble getting decent volume from an 8Ohm .5W speaker. I was directed to use 4Ohm 3W speakers.  I tried an 8Ohm 2.5W speaker I took out of a CRT television amd that was fine, but it's too big for the donkey.  I got some 1.25" 4Ohm 3W speakers off ebay, but they did not produce enough sound.  The smaller Adafruit version did the trick.

Third, I cooked an SD card and a MusicMaker.  I think it was while I was experimenting with power options...I may have mis-connected something.  First symptom was that it could not initialize the SD card.  I replaced it, and it got past initialization and said it was playing music but it wasn't.  Back to Adafruit for replacement board.

The reason for the second Servo is that I decided to move the donkey's tail, too.  I move the Servos in opposite directions, just because for grins.

Here's my appearance with the project on Adafruit's Show and Tell. I'm on from about 11:30 to 14:00.

49 States!

I've been working HF for just over a year, and have been looking forward to qualifying for the ARRL "worked all states" (WAS) award.  After starting digital modes in February, I got up to 48 states, leaving just Maine and Hawaii.  I did not think ME would be a problem, since I live in Massachusetts, but it proved to be difficult.

This weekend is the New England QSO Party, so I figured that this would be my chance. I am not hearing a lot on 40 meters today (the most likely band for me to hear ME on), but I did get 1 ME confirmed now I just need Hawaii.

Any HI hams out there wanna help me out?

Head Move Donkey V02 in-process

Adafruit Feather M0, with MusicMaker and PWM/Servo FeatherWing stacked, running the Head Move Donkey code: plays
"Donkey Serenade" while moving the servo about 60 deg right and left to move the head.
As described in detail in this post, I recreated a wind-up toy that I bought for my daughter (an infant in 1978) with a Pro Trinket 3V and other components.  In the 2.5 years since, I've gotten a little smarter and the available technology has gotten a lot better, so I thought I'd try a version 2.  The biggest difference is that I needed fewer components. 
Donkey V01 
In the original, I needed an SD card reader, an amplifier, and a PWM/Servo Board. I still need those things, but the Adafruit Feather System makes it a lot simpler, eliminating most of the wiring and some of the code.  Also the Feather uses a ATSAMD21G18 @ 48MHz with 3.3V logic/power and 256KB of FLASH + 32KB of RAM while the Trinket uses the ATmega328P  at 12MHz with 28K of flash, and 2K of, the M0 is much more powerful.

Power management is slightly different. I was able to power the Trinket from a 4xAA battery pack, using the 3V output to power the SD card and the 6V to power the Amp and servo driver.  Logic levels were not a problem.  I power the M0 from a 3.7V LiPo and the Servo Wing from the 4xAA--again, the Servo is forgiving with respect to logic levels.  I probably should have had separate power sources in V01. One twist is that I'll need a DPST switch to turn on both power sources together.

Donkey V02 Circuit Working

Next steps are to construct and enclose the completed circuit and re-stuff the donkey.  Since the enclosure will be smaller, I'm going to try to get the batteries inside the donkey this time.

Fun with Robots, IR Decoding, LED Matrix, etc.

Fig 1: Three experiment--two with the samsung remote on the left, one with the Radio Shack remote on the right--to control a +Adafruit Industries 8x8 Bicolor LED Matrix
I haven't posted in a while because several interests have kept me very busy. This all started withe the +Parallax Board of Education (BOE) Robot kit. I asked for and received on for Christmas a couple of years ago and let it ripen until I was ready.  I decided that it would make a good project to do with my 7-year-old granddaughter when she visits this summer--but first, I should make sure that I can build it without a lot of fumbling. Fumbling is good, but watching me figure out what dumb thing I did is not always interesting to a 7yr-old. I followed the tutorial and learned quite a bit, The last project that I did used infrared for proximity sensing to avoid obstacles. At the same time, +Adafruit Industries, via The Desk of Lady Ada, provided some great information on IR. So, I decided to play and learn further.
Fig 2: +Parallax BOE Bot with 2 IR transmitters aand 2 IR receivers

IR Decoding the Hard Way

Following the +Adafruit Industries tutorial on IR Sensing, I was able to decode only some of the buttons on my Samsung TV Remote (see Figure 1). Using the remote is a 2-step process: first decode the signals send by the buttons, then use the decoded signals in a different sketch that takes action based on the buttons. Using this method (see the Raw IR Decoder and ircommander code on github), I was able to decode some of the buttons and use them in a sketch.  

Quick diversion:  I have had big plans to use a 32x32 LED Matrix that I bought in a parking assistant project that will display faces to convey the emotions evoked by a car getting increasingly closer. I decided to use the 8x8 bicolor matrix and backpack to prove the concept, and use the remote to signal which face to display. Figure 1 shows the initialized yellow face (looks orange to me). So, I needed to follow the tutoral for the matrix and backback library.

I was able to merge code from the bicolor8x8 example code in the Adafruit LED Backpack library with code from the ircommander sketch referenced above. After adding the decoded remote buttons to a newly created library (see the IR Sensor tutorial and the project video cited at the end of this post), I was able to change the face on the matrix based on the remote buttons.

I found both the coding aspect and the operation of the technique to be less than perfect.  Maintaining a separate library with very long sequences of numbers just to test what button  was pressed seems a bit much. In operation, the code seems to reset itself randomly, and only respond to buttons when it feels like. This may be me, and I will investigate, but read on to see a much neater technique.

IR Decoding an Easier Way

After working through the above, I watched Lady Ada work through Chris Young's IRLib2 in one of the Desk of Lady Ada epdisodes cited above.  Chris, aka cyborg5, is a frequent visitor to the Adafruit Show and Tell, and has done a lot of great work (see his blog).  Both the decoding and the processing techniques are simplifies greatly, and his library handles several IR protocols. The IRLIB2 tutorial describes it all very well.  You wind up with one simple code that you supply in a sketch so you can determine what button was pressed--straightforward, and I was able to decode all the buttons with no missed presses. From there it was a matter of simplifying the sketch I wrote earlier to display faces on the LED matrix.  Again, the project video shows all this.

Controlling Motors with IR

Since we started with robots, I thought it would be interesting to control motors with IR.  It was a simple matter to modify the IRLib2 sketch above to direct the continuous rotation servos.  I took code from the BOE-Bot project, and code from the Adafruit_PWMServoDriver library tutorial, and it went smoothly.  The servos in the BOE-Bot are different from the Adafruit ones, so I had to go to the data sheet to see what values to use to get them to move as I wanted. I was able to decode all the buttons on the Samsung remote, and used the arrow keys to simulate moving the robot forward, back, left, and right.

I first did this without the PWM Servo FeatherWing. Because the feather is 3V logic, I needed a level shifter to handle the signals from the board to the servos. That worked, but added a few connections and I used the Arduino servo library as opposed to the Adafruit library which allowed for simpler code.

Another thing I needed to worry about was timer conflicts. I had come across this before, in my Donkey Project, but Chris' tutorial gave a straightforward explanation and solution. The problem is that the servo library uses Timer1 and on the 32u4 Feather IRLib2 does too. It was necessary to go into one of the associated libraries and change one line of code to re-assign the timer.  You'll get better instruction in the tutorial than I can give here.  Again, the project video shows the results.
Controlling 2 FS90R continuous rotation servos from an Adafruit BLE Feather and PWM Servo FeatherWing

Trying a Different Remote

A while back, Radio Shack sold some MAKE project kits, including robotics. During an earlier RS bankruptcy, I acquired a RS remote at a big discount and still had it in inventory, so I decided to try it out. Using the IRLib2 approach to decoding, I found the the protocol was not one of supported ones. A look at the datasheet for the PT2248 chip in the remote revealed that ot used the Toshiba protocol. So, I had to go back to the hard way, and I got that to work.  See the video.

IR Affects the BOE-Bot

Just for grins, I took out the BOE-Bot, let it runon the floor, and chased it with a remote.  The bot's IR retrievers detected the transmissions, and the bot reacted accordingly (moving left or right as if it had detected an obstacle).

Andy's Ham V20 Virtual Machine Update

When last we left Andy's Ham, in this post, I had Andy's linux ham radio distribution installed in a virtual machine running on a Windows 10 host under Virtualbox. The installation was successful, but I still had to run some software.

The first step was to get the virtual machine to recognize my my Signalink USB. After starting up the VM, in Virtualbox, I went to "Settings/USB" and found "Burr-Brown from TI USB Audio Codec." I ticked that, and for a couple of weeks I could not get the VM to do anything but freeze up.  I was pretty sure that that was the Signalink, so I scoured the interwebs for information, to no avail. In desperation, In installed AndysHam on a different physical machine and plugged in the Signalink. The same option appeared in USB settings, and it worked. This time I notice the options for USB controller: 1.0, 2.0, and 3.0.  In both cases I had ticked 2.0.  However, the computer with the VM has some USB 3.0 ports (see this post on my upgrade). I had not noticed that I had plugged the Signalink into a 3.0 port (I just reached around to the back of the computer and plugged it in where I could). I went back and ticked 3.0 and all was well. The VM did not freeze and the Signalink showed up as an option in the software (fldigi and WSJT-X).
VirtualBox USB settings for Signalink (be sure to enable the correct USB controller)

If I have WSJT-X (e.g.) running on the host, the guest grabs the USB port for the Signalink and holds it until the VM is shut down. So, I can run the software on the guest, but not the host. On the host, the Signalink is not an option for sound card until the guest is shut down. It may be necessary to redesignate the sound card every time--however, if you plan to use the Signalink in the guest only, this is not an issue.

So, I got AndysHam to work in two environments--on a stand-alone machine and as a guest machine under Virtualbox.  There are a couple of things I need to get used to. First, JTAlert does not run on linux.  I have been enjoying the features, so I'm not sure I want to give that up. Second, I find the set up a little inflexible.  I'm sure I can do what I want to do, but it's been set up to provide most things, and for under-powered computers--which mine is not.  

I'll work with it some more, and if I have anything useful to say in the future I will post it here.

Andy's Ham Version 20 VM Installation

I have recently made progress with digital modes.  On 2 Meters, I have been successful with packet on my Alinco DR-135. I am considering a Tigertronics Signalink as sound card interface for my Ten Tec Jupiter.

Meanwhile, I need software.  I could pursue commercial options like Ham Radio Deluxe, but I decided to explore some free options.  I discovered KB1OIQ - Andy's Ham Radio Linux .  The advantage is that it includes a variety of free packages, including logging, rig control, satellite tracking, and a variety of others.

I had 3 options for installation:
  1. Turn my Windows 10 system into a dual boot, and boot into linux when I want to play radio and Windows for other applications
  2. Install Andy's Ham on a separate matching dedicated to playing radio
  3. Install Andy's Ham as a virtual machine (VM), running under Windows
I chose option 3, because dual booting can be a pain and a separate computer can add complexity. Running a VM allows both Windows and linux to be available at the same time. To do that, I needed virtualization software. I chose VirtualBox because I have used it before at work and home.  Installation on Windows is simple: download the correct version at the link just provided, and run the .exe.  It makes sense to download the Extension Pack and install it, too (honestly, I don't know why that's an option--just always install it).

Once VirtualBox is installed:
  1. run it and create a VM (follow the prompts--consult the user documentation at the download link if you need to). The only change I needed to make from defaults was disk size--it defaults to 8G but I gave it 20G--Ubuntu says it needs ~20. 
  2. download Andy's Ham (link in the second paragraph above)
  3. in VirtualBox, click settings, then storage for the machine you created. Next to Optical Drive on the right, click on the CD image and point it to the downloaded Andy's Ham .iso file.
    Installing Andy's Ham in a VM
    1. Start the VM--follow the current instructions. For me I chose the "live" option when prompted. When asked for a user id gave it "ubuntu" and presses enter on password (no Password). Once the VM comes up, you can play with the installation, but nothing is permanent until you install to the VN's hard drive. To do that, click on "Debian"  at the lower left, an in the menu that pops up click "System" then "Install to Hard Disk."  This will take a while, but cannot run unattended because you need to respond to some prompts along the way.
    2. Restart the VM (click on machine/ACPI shutdown, then double click the machine name), and you're done.  One of the prompts you responded to created a user and password--use those to log in to your new machine.
    This is a nice remix of Ubuntu if all you want to do is play radio.  I'm going to have to play to see how to add back some Ubuntu features that I'm used to.  I will post again after I've had a chance to play/learn.
