Hi, I thought I'd better introduce myself to the group now that I am on the air. I am operational on 181kHz and have had resonable results considering I'm a beginner at LF! In just one evening I was

Is anybody doing any work with Kahn Envelope Elimination and Restoration technology on LF? It would be especially applicable to those of us with nonlinear LF transmitters (class C, D, E) wishing to r

Scott, If the station you mean is the FSK one on 135.92500 and 135.97500kHz, it's normally good copy here in the afternoon and evening. For what it is worth, the two tones this station transmits are

Jay, I thought by now everybody knew how to find an email address for another internet-connected Amateur! Con ZL2AFP reads this reflector, and can be emailed at: [email protected] 73, Murray ZL1B

I can now supply the updated Clicklock2 Help File and executable together as a ZIP. The file size is 690kB, and most of that is the PDF file! 73, Murray ZL1BPU

Dave, There are two issues here - first, the signal being on a non-integer frequency, and second, the signal having a non-GPS locked carrier phase. The first can be handled by setting a non-integer o

I'm about to have a play with Scott's new PhaseScope, but I can tell you that I have been getting very good results using another program based on the same technique, also using Peter's clever ideas.

Fellow LFers, Con ZL2AFP has also written a program using Peter G3PLX's Clicklock technique. Clicklock allows any stable receiver to synchronously receive LF signals, and integrate them over minutes,

For anyone interested in making GPS coherent transmissions (for use with G3PLX/VE7TIL/ZL2AFP Clicklock coherent software), the ZL1BPU LF Exciter now has the capability. The new Version D6b firmware p

Dave, Put it this way... I see a weak carrier at 20kHz that has varying day/night strength, but fairly constant phase. I've no way of verifying for sure where it's from, or whether it is keyed, as I

Uwe, It certainly looks like 2nd harmonic problems to me too, probably linearity (gain) imbalance. Another thing you will have discovered is that with the harmonic information Peter mentioned, the SW

Bryan, Let me know a suitable email address that can accept megabyte-sized attachments and I'll mail my compiler to you. The one I have is the old Microsoft Quick Basic compiler (V4.22 I think), whic

Folks, I find it difficult to understand why one would want to generate DFCW with up-down buttons, when there are plenty of ways to do it reliably with audio. It would be quite trivial to write a BAS
