Hi Stewart and all, I was also thinking that you could send wolf on the divide down CW transmitters that some folks use. By injecting the audio tone from a PC into a 13.6MHz transceiver operating SSB
Hi all, Brian CT1DRP kindly mailed me a CD-R with many recordings of Jim M0BMU's WOLF signals, some of which could be decoded and some not. In the course of playing with them, I added many diagnostic
Hi Mike, The phrase is very common in the U.S. Just for laughs, I did an altavista search and 30778 pages were found. With "+host:uk" added, the hit count went down to 1328. Results in the top 20 fro
Jim and all, Sorry that I don't have a ZIP drive, but if you can burn a CDROM, that would be a good way to transfer some big .wav files. I'm in Paris now; it won't take long to get here by post. If y
Hi Andy and all, A recent discussion with G3PLX made something click in my mind about the widespread adoption of Wolf for LF communications, and is it really the right way to go ? WOLF is far from an
Hi All, Sorry, I just discovered that my attachment size limit is only 3.8 MB. That should still be enough for 7 minutes at 8 kHz, 8 bits. 73, Stewart Hi Mike, Jim, and all, I would like to get copie
Hi Mike, Jim, and all, I would like to get copies of your recordings, when you failed to copy Larry, so I can try to improve WOLF's QRM rejection and tracking. Recordings from others are also welcome
Hi all, I've been thinking about coming to Friedrichshafen, and would probably arrive Fri. evening and leave Sun. morning. Can someone recommend a decent hotel (~ DM 150) within walking distance of t
Hi all, Although the recent amateur VLF contacts were fairly short range, I believe that DX operation is possible, perhaps even across the pond. Please don't laugh, but I think that the very high sta
Hi David and all, Jim's message, sent with Pegasus, had mime type text/enriched, and indeed had the control codes. However, it doesn't seem to be valid rtf data. I'm running OE 6 under Win XP here, a
Just for grins, I recorded a 15 sec .wav file of the 73.3 kHz RTTY signal and uploaded it at: www.qsl.net/w4dex/73khzRTTY.wav It sounds strong enough I almost believe it would print here if the stat
Hi all, It appears that the W95.Hybris.gen virus was posted here. If you accidentally opened it, see http://www.symantec.com/avcenter/venc/data/w95.hybris.gen.html The machine it was sent from is in
Hi all, 136 kHz = 17 * 8 kHz. Almost anything to do with telephony has a frame rate of 8 kHz, including T1/E1, ISDN, and xDSL. The old style carriers used multiples of 4 kHz. So what you are seeing i
Hi Rik and all, The current DFCW format is really a ternary signal. A space (interval of no signal) must be present between characters, because Morse is a variable length code. One must distinguish t
Hi Johan and all, I would think that you should be able to lock your Austron to this chain: GRI and Chain Name Station Latitude / Longitude Emission / Coding Delay Power in Kilowatts 8000 WESTERN RUS
Hi Dexter, Congratulations on receiving ZL6QH! I didn't realize that they were sending so fast. Is this a record for this speed? 73, Stewart http://www.qsl.net/w4dex/ZL6QHa1Dec01.jpg Looks like .4 Hz
Hi Dexter and all, Yes the 73.6 kHz signal is 75 Hz shift but I don't know about it rate. Can I determine this by viewing with Cool Edit? I have a one minuet .wav file, close to 1 MB, I could send yo
Hi Dexter and all, I'm presently watching 75 kHz time signal which is better than 50 db above the noise in North Carolina. Radio Clock even shows the pluses but will not lock up because of the 73.6 k
Hi Jim and all, The 1 kHz filter sounds like a good idea. If you don't have strong carriers dominating the audio, then 8 bit samples should be fine. Also, if you keep the audio frequency fairly low,
