I use an SDR-IQ with output to Virtual Audio Cable VAC. The SDR-IQ is set to produce an 2 kHz audio output from 136-138 kHz so that 136 kHz = 0 Hz audio. SL, Opera WSPR and now Wolf are connected via the VAC. With these settings a Wolf signal Tx = 137.249 kHz should produce an audio signal of 1249 kHz and I have set the Wolf centre frequency to this. I wait to see if I get any decodes! However, there may be other issues such as sample rate for the VAC. What happens when different programs using different sample rates connect to a single VAC? I have just been experimenting with the dual receive facility of the SDR-IQ and stereo processing mode of SL to feed the 19580.0 kHz signal (GBZ, MSK200) into the left channel and 136-138 KHz into the right. The SL sampling rate detector shows a "lock" and measures the SR error of the VAC. But whether this is actually of benefit I'm not sure!! 73 Terry GW0EZY -----Original Message----- From: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org] On Behalf Of Chris 4X1RF Sent: 29 January 2012 00:21 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: WD2XES WOLF Saturday Night Terry, John, In my case I've chosen 1500Hz for no particular reason, the receiver is a direct conversion front-end feeding an M-Audio board run at 48ks/s and SpectrumLab as the mixer-filter-demodulator stage. Audio is routed to Wolf with VAC. QRV now on 137294 for the night... time to get some sleep.... 73s Chris 4X1RF On 1/29/12, John Andrews wrote: > Terry, > > In receiving, I use the default center frequency of 800 Hz, and put the > receiver into CW mode.
