Howdy radio aficionados,

On this July 4th we are pleased to reveal the packaging and engineering
prototype of Computeradio "Dream Radio One". It features stainless steel
cabinet which will fit in the carry-on luggage, color LCD display,
ergonomically designed controls (large tuning knob, key/paddles, foot switches
yet to come) with two top notch ham band receivers, transmitter, spectrum
analyzer/recorder with general coverage receiver in modular packaging with user
programmable software.
You can peek at the picture of the system at http://www.computeradio.us/

Happy Independence Day and let the Freedom Ring!

Congratulations, Yuri! Your DR1 looks great! It;s been evident from the
expertise displayed in your posts that you are a very knowledgeable guy, but
this revelation is icing on the cake--talk about surprise!.

I noticed that you moved from Canada to New Jersey in 1986. I lived in central
Jersey, in Dayton near Princeton, for 31 years while with RCA, but I hadn't
heard of Pine Brook. Is it near Edison? I have been in Edison many times,
including visiting the Edison Museum during the 1950's.

I wish you the best with your new project, Yuri,

Hi Walt,
Thanks for kind words, coming especially from you. I enjoyed your Dayton
presentation and been learning from the balun/matching wars here on the NG (I
am trying to avoid them, keeping systems 50 ohms all the way :-)

I figured timing is right from my personal side and where the technology is and
going. Ambitious project, but I always was intrigued by "impossible" tasks,
have tackled few in my professional career, so I hope that this one will be
"just another one."

Actually, I am debating if antenna tuner should be included, or in higher class
of radio one should expect amplifier or tuned antennas to follow. It can always
be an option, they are getting small (our expected output is 100W) and should
fit inside.

The DR1 is my present to America and hams on 4th of July in thanks for
accepting this BUm in search of freedom.

Pine Brook is in Montville township, area where Morse and Vail pioneered the
telegraph stuff, next to Boonton (Instruments ex home), by intersections of Hwy
80 & 287, about 8 miles north of Morristown. There is still some of that spirit
floating around here.

God Bless America!
73 and thanks again!

Hey Yuri:

Congratulations. Great start.

Outside of stainless steel looks great, and as we all know there's nothing
like cold rolled steel for good emc control, ruggedization (smacks of MIL
STD 810)and the steel could also be used for conduction cooling the PA to
eliminate fan and fan noise.

Overall I believe the "dream package" needs a little "miniaturization".

Big flat color LCD screen is fine, big fat tuning knobs are great too,
especially good for us old timers with dimming eyes and waning fine motor
control. By now most have mastered the keyboard so I approve...

But... radio/cpu chassis could be smaller, with today's technology y'all
should be able to fit everything but the power amp inside the keyboard.

Now that you've got the outside done, it's on to the tough part... the
insides!

Most, but not all, of the innards can/should be "integrated" these days.

Plunk down a MIPS 64 core or two, run em with real time Open Source Linux to
keep expense down, throw in a couple of SHARC DSP's, 24 bit ADC/DAs, and a
couple of those big Xilinx FPGA's and there's nothing between you and
success but software!

;-)

Good luck, I wish I had the time to help ya'll with the Dream, but I'm too
busy now getting baby into the air...

Best wishes on The Fourth from another who has also adopted the USA as his
own. Thank you USA for all the sacrifices you have made over the years to
keep the world free!

Thanks for comments Peter. Geez, I tried to minimize the package, but this is
about the smallest I could come up with, there is just enough space inside for
the air to flow. It is a complete station, 2 (or more) ham band RXes, 1 (or
more) TXes, GC RX, spectrum analyzer, display/recorder, 100 W PA with super
filters, 6 antenna switching and RX protection, PS, antenna/rotor controls,
rear panel PS exhaust and all the connectors plus, while keeping 6 PCI slots
for max flexibility (VHF/UHF converters). DR1 replaces just about full desktop
of existing boxes (FM and TV tuners incl.) and less than half the weight of
regular TRX. Also trying to accomodate present and future variety of hardware,
preserving modularity. All you need is to add the amplifier (carry-on PA1
coming after DR1) and hook your antennas.

The pocket version will be the next project :-)

Hi Yuri,

I don't know what happened. I composed a long response msg to you, and as I was
getting ready to send it the screen flipped to the next post below, the one from
Peter. I'm using Agen, and it's not very user friendly. I've searched Agent as
far as I can, but the msg is gone.

Trying to recap some of the original msg, I said I made a Dayton presentation in
either 1983 or 84. My only time at Dayton since then was in 2001 to kick off the
debut of Reflections 2, but I made no presentation then. Were you there in
either 1983 or 84, or could you have mistaken me for someone else at a later
time?

I lived in Dayton, NJ from 1949 to 1980, when I retired to DeLand, Florida. When
ragchewing on the air people asked where Dayton is. So I told them I live about
800 mi east of Hamvention Town.

I now live 6 mo in DeLand and 6 mo in my home town of Mt. Pleasant Michigan,
where I am now, a city of about 26,000 pop. There are more than a hundred hams
here now, but from 1933 (when I first became licensed) until 1939, I was the
only ham in the entire county.

I was telling you about two other items in the msg that got lost, but I can't
remember what the were--par for the course at 85, but pretty good that I
recalled the three items above, eh?

CUL, Walt

Check the Recycle bin?

I was almost every year in Dayton untill we moved from Toronto to NJ in 86. I
am still uncomfortable with Smith chart, I rather design the antennas to be 50
ohms to 50 ohm cable and when monoband, I prefer to use Bazooka balun/filter. I
prefer moving waves rather than them standing :-)

Congrats on your 85 and going, just stay away from carbohydrates and have a
drink with meal.

We are about 40 min drive from Manhattan and I go there few times a week to
"enjoy" the traffic and parking tickets.

73 and thanks again!
