FWIW: I was wondering why anyone would want a VACuum tube SDR.... the power drain would be excruciating. For those of us who don't know. . .

"Virtual Audio Cable, more commonly referred to as VAC is a third-party software package that facilitates digital audio transfer between PowerSDR and other sound card enabled programs, like most digital mode programs (MixW, Digipan, MMTTY, etc.). VAC is able to do this because it is a kernel mode Windows device driver that emulates a sound card."

It's not nice to acronymnize without stating intentions first.
;-)
Keep on coding! I'm totally impressed so far!

own VAC driver which I can ship with the console.


Re: 1.1 (beta) build 417 ECSS and AM Sync de-modulation still needs work

Bruce,

That is close to or perhaps actually the frequency I heard the first weird sounds just above the 40 meter ham band trying to SWL some AM stations. 

I reduced the RF input on the software, like it was over loading, but before I changed the attenuator I looked to see if the SDR-IR overload red led was on, it wasn't.

It didn't do too bad last night listening to AM 740 from Toronto, Canada.  Some email comments were using 90 khz.  When I switch from 190 to 90 or 48 the station is lost.  I get it back when I tune up or down and back on frequency. 

Something just not right with the AM demodulation of ECSS and AM Sync.  I use SpectraVue and Winrad as my basis for checking.

Wow!� You get CFZM from Toronto way out there too! I love that station and listen to it frequently at night. I did notice last night that the propagation was not the greatest and seemed to be stronger from the South here in Michigan. I lost the station too for a bit but was listening on a 1941 Zenith tube set I was working on at the time.� Lately, I have taken to listening on the Internet stream.

Well, back on theme... I will try some of the adjustments you mention and I suspect I can make improvements but I wanted Simon to be able to get at least two instances of this issue to work with and I wanted to give you some assurance that it may not be totally your hardware configuration.

Thanks.

As for a VAC - what I need to do is provide IQ and audio data via various
VACs, for example to deliver PCM (aka normal audio) and IQ data for each
VFO. So you'll be able to use all three VFOs and have the output for each
VFO going to a different program.
Simon,

This sounds exciting!

Anyway, it's easy to say this, writing is a different matter, then comes the aggravation of signing the drivers :)

Re: 417 - Pause for Applause

robengberts <pa0rwe@...>
 

Hi Simon,

I have tested the B.417 version after I have skipped some earlier versions, and indeed applause also from me!
I did not get any crashes any more. The console is working stable and with less CPU load (<50%).
Also the AM and FM mode are working well on 48 and 96 KHz sample rate.
Great job!

But I have (of course hi) some questions:
- I missed the possibility to switch on and select an USB soundcard when the console is running. I have to close down the console before I can selected an other card.
- When the digital clock is activated it is no longer necessary to show the clock above the frequency display. It is better to show the frequency where the filter is set on and not switch back to the clock after a while.
- I tested the signal strength respons in the display and on the s-meter. The display is OK, when I changed my RF generator 10 dB, on the display it is also exact 10dB. But not on the S-meter. Every 10dB change of signal strenght is about 8-9 dB on the S-meter.
- It should be nice if there is a possibility to adjust the signal strenght on the display exact to the strenght of the input signal (calibration). Is the calibrate option made for that reason but not operational?
- Is it possible in RTTY mode to determine the shift automaticly?

Later on I will do some test with receiving Wx satellites.

Please make a file using the same version of Winrad which I can use for testing. I suggest just 10 seconds or so. Put it in a ZIP or RAR and either send by email or FTP upload.
