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.

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?


Not that government spending is any proof of noteworthiness on the part of the vendor, but he seems to be doing OK..

Mr. Moore seems to have some background with SDR tech..

"Don Moore is president of AeroStream Communications, an SDR specialist. During the 1990s his company, NavRadio, developed VDL-2 technology and demonstrated transmission of graphical weather imagery in the NASA AGATE and AWIN programs."  http://www.aviationtoday.com/av/issue/columns/perspectives/Perspectives-Software-Radio-The-Bright-Side_701.html


Seems he studied at Michigan Technological University back in the late 60's.


Mr. Moore seems to have had government grants for research and development going back several years. A quick search turns up many projects, such as: H92222-05-C-0032




I have to ask though, why such a contemptuous attitude towards Mr. Moore?



And, I wonder what this is about? :

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!”

Beyond bizarre. The costly CR-1 is now for sale online. Potential buyers are begging for additional  performance specs or at least a comparison with a recognized high performance receiver (and not that handheld thingie with a BNC whip) and this photo is what Moore's buddy provides:

Nice.. Looks like he's absolutely unqualified to program a remote  Grin

Ok, so.. IMO

Like:

Commradio is very upfront about what might be perceived as "limitations" of the radio.

Form factor

Concept

Would like to see:

DRM decoding.

Continuously variable filter width from 1-50kHz on HF, 1-230kHz VHF/UHF

Panoramic filter status display and/or Panadaptor funtion

IF port on rear panel, OR...

USB I/Q port on rear panel


Wondering:

Why no 30-50MHz?

Why no carry case? Even nylon would be nice.



The radio is intriguing, and I'd certainly like to own one, but this product is one that I will likely have to see in person before plunking down $500. It's not about the money, but the value when compared to or just in a fleet with other options I presently own. Would I really use it much? Sure! what a great mobile device. It would sit right up on the dash, no problem, replacing my PCR-1500 and remote head.

Based on Mr. Moore's credentials and the pictures provided, I'd expect the CR-1 to be a fine, solid piece of gear.

Now.. On the other hand...

If it had DRM decoding standard and an I/Q port, right now, SOLD!

Why don't you just phone them (him?) and ask your questions? 303-279-3671

That would also give some idea about customer service.

Was that fast email reply just an autoresponder? What did you learn from it about the questions you've asked?

I only asked if the radio was in stock, and received a direct reply from Don, it seemed. As for the shipping date stated on the website, one might presume that there have been orders placed over the past few weeks, and that those will be fulfilled on the 22nd, with subsequent orders to be fulfilled within two weeks of placing a new order.

I'll wait til someone posts a review of the production radio before making my final decision.

While Commradio.com still says in red that shipping starts on February 22 for new orders, there has been a small delay:

Don's friend WB2KTG says: "Being a bit of a perfectionist, Don would rather be a day or two behind shipment dates than ship a product which wouldn't fulfill his and your expectations!"

Hi well thats good if he can fix the problems with the radio but the shipping date keeps changing it would be better if he fixed all the problems first and then can have a definite date for delivery..

Two more CR-1 videos were just posted on YT
http://www.youtube.com/watch?v=i07GUs3tJkY
http://www.youtube.com/watch?v=vOI63NvjUxY

"S-meter" seems to consist of the two characters at the display's bottom left.  i.e. "S9"
Does it display dB above nine?
