So who in the heck is Don Moore N0HDX?

Let's see:

"It draws on my experience as a kid building Knight Kits, from my paper route earnings through currently owning a classic Drake 2B and a Zenith Transoceanic; my benchmarks for enjoyable, high quality short wave listening. "

Then he adds an hefty aluminum knob. And Voila, a cutting edge SDR radio!

From his Eham bio:
" I now develop commercial grade, aviation (VHF) transceivers and plan to intorduce [sic] a SSB rig hopefully in 2003/2004.

73, N0HDX, Don"

Anyone know this guy or anything about his background? Has a general class license apparently.

Here's some discussion on an SWL site:

The CR-1 specs are really buried in that website:
---------------------------------------------
"Product Information

Introducing the New CR-1 Communications Receiver

The CR-1 is a small, low-power, ruggedly constructed radio receiver that is finding a niche in the world of SWL’s (short wave listeners) and amateur radio enthusiasts alike.

The CR-1 is a new Software Defined Radio (SDR) from the designers of miniature wideband signal intelligence receivers, developed for special-operations units, and rugged business-jet data-link transceivers.

The CR-1 SDR is independent of a host PC, using embedded digital signal processing technology providing a degree of portability  and performance previously unavailable  to the radio enthusiast.

As one potential customer noted: “It’s an SDR with knobs, keys, and a display!”

Great web site.......

The thing that bothers the heck out of me are a few things,

I don't see any type of FCC Certification on the unit or in the specs page, As far as I remember "any radiator (that which emits radio energy),
whether or not intentional, must be licensed unless it meets 47 CFR 15 or is otherwise exempted by the FCC."


Last I remembered any "computerized type item", especially if it contains a microprocessor, has the potential to emit RF.

It is also interesting that the web site is practically bare...
at the top is:

303-279-3671, Home, My Account Sign in or Create an account, View Cart


I also don't understand why "Product Info" button has to take you to offsite to a third party
called...https://store-ckohqsq.mybigcommerce.com/cr-1-communications-receiver/

The product specs, warranty, and other information can't appear on the main web site?

Just my opinion.

I know that my company would not be able to sell an item like this without
a FCC certification. I had to have a FCC Type A certification back in the late 1980's
just to make and sell a secondary programmable keyboard for IBM PCs. A simple
keyboard with a Motorola N8042AH 8-Bit MCU was all it took to require certification.

A WB2KTG serves as something of a surrogate for the maker online. They're friends, WB2KTG says. Here he shows nice photos of the radio's innards:

http://forums.radioreference.com/software-defined-radio/256366-new-sdr-commradio-cr-1-a-4.html

http://forums.radioreference.com/software-defined-radio/256366-new-sdr-commradio-cr-1-a-3.html

Then WB2KTG claims the CR-1 can hear a 40 meter CW signal easily that could not even be detected on a ICOM-R20 handheld receiver and active antenna (an unusual setup for a comparison).

Thought this statement was funny: "There must be a contest going on 'cause this one guy has been pounding at about 20 WPM for the past hour or so. So far I'm impressed with the CR-1!"

Wow, 20 WPM! Must be a contest. Apparently WB2KTG isn't much of a CW op and "so far" he's impressed with the CR-1 based on listening for one station on 40 meters, of all bands! Not mentioned is that the CR-1 has only one bandwidth on CW, 1 kHz.

I agree with this posted comment: "It would be nice to find out more, to be certain. I'm a little taken aback by the fact that the guy is looking for people to get on the waiting list for purchase, while he comes up way short in an explanation of exactly WHAT is being purchased and how it's going to work."

As for N0HDX's credentials, I'm still finding almost nothing. Judging by call lookups, he doesn't appear to be active on the air.

Apparently, this is his day job:
http://www.aerostream.com/index.html

There is a picture of the cr-1 which shows a spectrum display on the oled screen (on the above website).  On the video's that are on youtube, I don't even see an s-meter.  I'm still interested to see how it performs out in the wild.

Hi well the date for delivery of the CR-1 has been changed from Febuary 15th to the 22nd.The youtube video shows he is listenning to radio stations with lots of power which most people can pick up with any radio when it comes to emails takes a long time to get a reply and if you want to make a name for youself in the receiver market you have to compete with aor,alinco,icom,ten tec and no overseas sales available till may.I
am ordering mine this week it will be intresting to see how it compares to other receivers..

From the few photos and one video, the CR-1 doesn't currently seem have an S-meter, but it may have a rudimentary panadaptor which can be seen in this picture, but none of the others. http://www.aerostream.com/images/cr1.jpg

Looks like the guy, even handicapped by holding only a General Class Amateur Radio license  Roll Eyes , has some achievements of note in the realm of commercial radio products.

Nice form factor. Good specs on paper.

For the price of $650, or even $500, lacking a computer interface or I/Q port makes it a bit of a boutique radio.

Still, nice looking rig.

I only found what he posted about himself on his two sites and even that wasn't much. Noteworthy was what wasn't posted, such as his educational background and where he has worked since becoming a ham decades ago.

What "achievements of note" are you referring to?
