All-mode transceiver
David Lininger
Some months ago there was some chatter about a new all-mode transceiver
(kit?) that was very inexpensive. As I recall, it was going to be for sale somewhere in the last month or two of 2018. Since then I haven't heard anything more, and, of course, I can't find any of those emails. Does anyone remember what I'm talking about? Did it actually appear? Has anyone used it yet? -- David Lininger, kb0zke Rev. 2:10 kb0zke@... |

Thanks, Mike. This looks like it would be something that I can use, and

the price seems almost too good to be true. Of course, I'd have to add the cost of a Windows computer, unless my Mac can run it, but that shouldn't be more than $100 or so. On 8/5/19 19:18, Mike Carden - VK1MC wrote:

No external computer is required. For details see: You might want computer for your logging or something. If you do computer logging you may already have the computer for that. 73, Bill KU8H On 5/8/19 9:13 PM, David Lininger wrote:

Thanks. Good to know. At this point I don't do computer logging, but

that may change. I had assumed that a software defined radio required a computer. On 8/5/19 20:52, Bill Cromwell wrote:

It does require a 'computer'. A microcontroller toe be specific. It's built in. 73, Bill KU8H On 5/9/19 9:28 AM, David Lininger wrote:

My understanding is that Hans is using the microcontroller for DSP and other tasks for the transceiver, such as various filters. I believe all of the processing power he needs is contained within the QSX itself.

That's what it says on Hans' web site in the QSX page. Having microcontrollers of various capabilities inside the radio is not new. Some of the confusion may be from the "SDR". There are multiple configurations and some of the "easier" ones do use a PC and sound card. The SoftRock radios come to mind. Those functions can be built into the radio and not by pounting PC inside. I suspect the QSX is not "simple":) 73, Bill KU8H On 5/9/19 9:50 AM, Jack via Groups.Io wrote:

The DSP capabilities of current ucontrollers are nothing less than stunning

for example check the ARM Cortex development boards from STM micro. Another approach ..(my current project) utilizes an Analog Devices codec ADAU1761 with built in DSP.? the complete receiver consists of 4 chips, Si5351, switching mixer, ADAU1761 codec, and a small ucontroller to provide tuning parameters, button and knob inputs, display and timing.? Included in the CODEC DSP are selectable filtering (CW/SSB), AGC, selectable sideband demodulation all in 56bit fixed point...better precision than single precision floating point! The transmitter section SSB/CW using much of the receiver design. Selectable sideband, speech compressor. everything runs on 3.3v except the PA.

Hi all
Yes, QSX, I am working on it... fast as I can... all specs and details are here Hopefully the page is not unclear... I mention "SDR" 2 times on the page... the first one is the very first item on the list of features: - Software Defined Radio (SDR) technology with standalone Digital Signal Processing (DSP), no PC required So yes, it has a powerful 32-bit ARM Cortex M4 micro built-in, which handles all the DSP functions. The fact it is internally SDR does not mean a computer is needed ("standalone" and "no PC required"). This applies to many radios these days including Elecraft KX2 and KX3 which have a similar architecture. A USB keyboard can be plugged directly into QSX and used to operate the radio in CW, RTTY or PSK31 - all standalone with no PC connected. The second mention of SDR is further down the specs: - QSX can appear to a PC as a high performance 24-bit USB sound card and radio - for digital modes from a PC e.g. FT8, either demodulated or as I-Q for PC SDR programs Which means you could also, if you wish, use the QSX entirely controlled by a PC SDR program. The QSX will output very high performance 24-but I and Q channels to the PC - with no need for an expensive USB soundcard etc. QSX already contains the USB soundcard. All you need is a single USB cable between QSX and the PC; the same USB connection also simultaneously shows the QSX as a Virtual COM port (serial port) for sending CAT control commands to the QSX. So you have the best of both worlds: 1) a standalone high performance all-band all-mode 10W HF transceiver with built in DSP and lots of features, including plug-in USB keyboard operation of CW, RTTY and PSK31 2) Use it as an SDR with PC SDR software if you wish 73 Hans G0UPL |
