Old friend Ross, (who needs to start his own blog), sent me some progress notes on how he's going trying to combine a SoftRock with WSPR software. He writes:
"I have found that the SoftRocks are not very stable when left to themselves. I have attached a screen dump of WSPR and SpecJT and also the list of spots on the site. You will see that the received spots are a lot more stable than the off-air reception by SoftRock Xtall+USB V9.0 Rx. Next that I will do is find the Kuhne crystal ovens that I have somewhere in Kabul, when I am up there in a week or so and attach to the Si570 local oscillator to keep at a steady 40 deg C and see how that affects the stability.
At least though I have got WSPR working through the Virtual Audio Cable OK and managed decodes."
Later:
"Have spent the entire night on 40m and, while the SDR is not as sensitive as the Icom, I have many spots on 40m overnight, including PY8ELO and an LX from South America. My fix for the drift will be a crystal heater such as Kuhne Electronics QH-40A - I have two sitting in my junk in Kabul and must find them. Next issue is to get a program that provides I and Q out for Txing on WSPR."
Ross tried various software to patch the audio but in the end:
"You know what, I had the solution already and did not see it because Rocky did not want to work with the el-cheapo USB sound card.
When I was home I found that WSPR just did not work properly with the in-built sound card in the MSI U100+ netbook that I got for WSPR and WSJT. I got a really cheap USB sound card and found that WSPR worked quite well with that. When I first tried Rocky the SDR prog I found that it did not like the el-cheapo USB but would only work with the in-built Realtek HD Soundcard and was stuffing around trying to get rid of all the associated drivers that did all the Dolby-surround and other tailoring on the sound - I wanted it barn-door-wide.
I also subsequently found a simpler SDR Rx prog called SDRadio by I2PHD which, strangely enough, will not work with the Realtek in-built but works fine with the el-cheapo USB - problem solved two USBs and an actaul hard cable cross-connected and Voila! Simple."
