probably i will start to T X in WOLF mode on 137.500 kHz starting from 20:00 UTC untill 21:00 UTC. '73 Valerio (IK5ZPV) Sorry, but I did not see this e-mail until Tuesday 3 April. Will you be on toni
I may be way off beam here but can we do anything with FSK? My understanding is that for voice transmissions NBFM and phase mod are differently achieved but result in roughly the same mathematics so
I can receive with good sensitivity down to 30 KHz. What European commercial could I try for and what is their transmission format? i doubt if I could hear or see you from GI without QRSS. i would be
G3YMC wrote (agreeing with GW4ALG): I appreciate the need for beacons for those doing transatlantic tests and similar, but the use of frequencies just below 136kHz is a disincentive to those with bas

Since it seems quite a few people won't be able to make it to the LF forum, perhaps now would be a good time to ask how many will be coming? I will be there. Mike, G3XDV (IO91VT) http://www.lf.thersg
Also, note that at the critical point on the error rate vs. S/N curve, when using a strong error correcting code like WOLF, 0.5dB can be the difference between no copy at all and perfect copy. Andy '
The top hat consists of eight 20 foot 1.25 inch diameter aluminum tubing mounted on two plywood disks. I have tested this antenna an it works very well. This antenna cost me about $1000.00 to build
If the voltage on the output of the coil is higher than that on the input then (for constant power) the current must be less. Nick G4WHO Ah. This is one of the great mysteries of loading coils that h
Many thanks to those who replied to my language query, both direct and via the reflector. Apologies for the off topic message but it seemed a quick way to solve a problem. I will restrict my messages
With apologies to UK readers, I am using this forum to survey non-UK amateurs about the term "on a shoestring" which the RSGB may be using in the title of a future project. I would like to know wheth

Decidedly the spectrogram-like programs are less than ideal for detecting the presence of a Wolf signal. Look at this picture : http://www.qsl.net/i2phd/argo/jimwolf.html It has been taken just a few
