Title: Dayton SDR News?
Post by: NI0Z on May 13, 2013, 11:29:45 AM
Any SDR news coming out of Dayton this year?

Last year Alinco was displaying their future SDR transceiver at Hamvention, but there wasn't many details on it other than it's projected price which was expected to be in the range of $800 US.  I'll be curious to see if that project has progressed at all.

Yup, there should be some news here, thats why I created a placeholder for it so as people hear about it they can share.  There should actually be news from a few companies.

Expect a launch Date from Flex.
Expect news from Apache-labs.
Expect at least one new SDR from someone.
I expect a KX3 Amp announcement from Elecraft.

Let's see what we get!

Apache Labs appears to be a no show!  Too bad as I have a pocket full US $$$ too!

They are going to be running web specials regardless..

They did not get their visas and have to wait 2 more weeks to get them  :'(

SSB Electronics has released their Zeus ZX-1 SDR.  4 MHz. wide spectrum display, USB to PC connection. $1600.00 .  The German rep told me the software was written in Russia.  Very clean little box. Available for immediate shipment.

Alinco reports their DX-SR9T will beready the ship in a couple of months.  This looks drastically different than what they were showing last year, and it appears to have become a hybrid oof sorts. Here's it's cut sheet

Alinco seems to do alright with VHF/UHF handhelds and mobile rigs, at least the ones I've owned in the past. But judging by some of their previous entries into the HF market, I don't know if I can get excited about them doing an SDR.

How much is the Alinco?

There are tons of pics of the DX-SR9T on the web since last year. It looks like the 8. The difference is they may have included the "SDR" function", which is just an I/Q output like on the DX-R8T/receiver. It allows up to 48kHz sampling. The free KG-SDR software is clunky. Still, at $800, you get a $800 amateur HF transceiver with an I/Q output.

IQ outputs with fairly wide bandwidth, perhaps as digital outputs, might become more common. It's a pretty useful transitional step from analog knob radio to full on SDR, and would be nice for "sound card modes" and such.

I wonder, though about IQ audio inputs to the Tx chain: it would be useful.. If they're wide band, then you have problems with the FCC (how do you prevent out of band emission or bad image cancellation).

I could see a hybrid being very practical.. Basically a conventional SSB transmitter (e.g. audio input with 6-10 kHz BW) combined with a receiver with a wide output.  You could still do a cool waterfall display and click to tune (sending the Tx freq command to the radio).

And probably more useful today than a First IF output feeding an analog pan display.
Sure you couldn't do some of the fancier transmit stuff (predistortion, polar amplifiers, etc.) but the vast majority of hams interested in SDR wouldn't care.

A shame  some company cant produce a radio like the ADAT transceiver  for the mass amateur radio market. Unfortunately there does not appear to be  a ham radio company with the engineering expertise of ADAT that produce such a radio. I dont really know why the ADAT company has kept such a low marketing profile especially in such an important market like the USA. Its really too understand why  are not very active marketing their product. Once you use  an ADAT radio you soon appreciate the virtues of putting a SDR radio into a stand alone box. If a company like Icom produced a radio  like the ADAT transceiver it would be a runaway success.

The ham radio transceiver manufacturers are very bad at doing  basic market research, they are not very proactive at exploiting the hot button issues in the ham radio market for new products. All we seem to get is  same old crap.
Every year the  release  of more radio models with useless features that nobody needs, the  performance deficit is glaringly obvious.

There is so much more  that could be offered  if they tried. The feeling that I get  is that the ham radio business is at the end of its product life cycle. Its about too die and blow away  because of technology obsolescence. The new
affordable SDR market is making life difficult for manufacturers. However if they grabbed the bull by the horns and start delivering advanced technology features hams will buy these new products rather than the stale bread  that they offer year after year.

ADAT appears to have died on the vine. I wonder why? Price? Looks? Output? All of the afore? The definition of "boutique"? Still, a rather nice piece of gear on paper.

What if.... Imagine an "appliance" type SDR with the intensive processing done on-board and network interface, with an available optional standalone hardware "faceplate" with touchscreen, knobs and buttons, that would connect via ethernet cable, POE powered from the appliance for local operation.

You are prone to attacking Flex a lot of the time but most of what you say above is true and it's the "big three" that are the most guilty. That's why a company like Flex was such a breath of fresh air.  There is fault to be found with Flex and they probably could produce better radios but what they have produced is still worlds better than the same old crap that the Japanese manufacturers have been selling forever. For years, the Japanese manufacturers have been "laughing all the way to the bank" at the ignorance and gullibility of the average ham operator.

The brand spanking new Yaesu FT-DX-1200 uses a DSP chip dated 2008.

This is not at all surprising and I have seen this many, many times. They (the manufacturers) will buy chips by the boat load to get the price down to pennies per chip and then use the same chips on model after model for as long as possible.

But heck this has been going on in radio and electronics since I got into it in the 1960s. milk as much as they can out of what they currently have.

And as been stated before, you are dealing with a clientele with as much on the ball as the members of Spinal Tap.   https://www.youtube.com/watch?v=ll7rWiY5obI (https://www.youtube.com/watch?v=ll7rWiY5obI)
