Many mails. I'm just answering your first one, pse QRX ;-) Can the WOLF10 program configured to generate a 8970 Hz audio output? I don't know about the WOLF10 program, but Stewart's original command-
Markus: Looks like I was locked on to your signal and almost got to the SNR for a good decode just before you stopped transmitting. Oh well, next time. Thanks for the signal. 73, Bill VE2IQ 22:13:34
After numerous brief power outages here causing problems with my GPS-monitored OCXO, I finally put everything critical on a couple of UPS's (APC-400). Noticed switching noise on 137 Khz when AC plugs
Nice work John, that's amazing! 73, Bill VE2IQ In what must have been a cruel trick by the gods of propagation, your signal was sent to me, bypassing the QTH's of W1VD and VE2IQ. 2012-02-01 03:46:40
We sure hear it in Canada: it's CFH in Halifax, Nova Scotia. I wish they'd stop. Bill VE2IQ At 05:09 PM 2/26/2012, Rob M0DTS wrote: Hi All, I'm getting a broad signal at 137KHz on evenings with gradu
Sorry Markus but no hits here overnight. Thanks for the signal. Bill VE2IQ At 03:24 AM 2/1/2012, Markus DF6NM wrote: The Wolf signal has been on air last night from 21:25 to 8:05, with no apparent pr

AFRICAM Version 4.6 has been released. A bug in the fine-resolution timing routines has been corrected. Hopefully, this will resolve a lot of erratic symptoms. I should have found it years ago :-) Do
Happy to report clean copy of CT1DRP's signal overnight on 135.9245 Khz. Signal was received in Ontario, Canada. Brian was running GPS-sync'd BPSK with an ASCII ID (no FEC) repeating every 2 minutes

Hi John and the group: I've just been looking at this MSK thing again and it doesn't look too bad. Yes, I know, you've heard that before, hi! I think I can put it into AFRICAM with some effort, as an

This is basically how the "PSKL" mode in COHERENT/AFRICA was done. Hmmm Bill, this mean I cannot patent it, being yours a "prior art" ? :-) Seriously talking, bad performance under weak signal condi

I have just uploaded AFRICAM 5.0 to my website. Essentially we have added another mode. I decided to compromise and call it FSK, not MSK :-) Since the demodulator can handle very narrow frequency shi
AFRICAM doesn't run well under Windows, even in a "DOS" box - I find it makes errors when it measures the internal CPU clock speed, and when it measures the sound card (and possibly even the Sigma-De
