201. LF: Loading coil siting (score: 1)
Author: "john sexton" <[email protected]>

Hi Guys, I moved my loading coil yesterday and the ground loss dropped from 103 ohms to 91 ohms. That is 12 ohms removed at a stroke! Previously it had stood in a corner of the patio by a wooden open

Hi Rich, If you publish a schedule especially for QRSS (with params) with times and exact frequencies for next weekend, I will certainly listen and who knows we might even make a QSO. 73, John, G4CNN

Hi All, Congrats to Bob (G8RW) and Jeff (F6BWO) on finally completing a QSO this morning. Jeff persisted in calling Bob, although Bob couldn't hear for a long time and finally they made it first with

Hi John, I have often heard the RTTY mark 73.56, space 73.64kHz, but it is not there this morning 010601 at 09.28, only the Rugby RTTY at 73.4, which is good clean RTTY at present. John, G4CNN ______

Hi Alberto, I too noticed the frequency was not spot on and it increased a little at start-up, but this is perhaps not surprising when you bear in mind the means of generation and its age. In fact I

Sorry Fabian, I had planned to listen, but some urgent QRL came up and I was unable to. So no report today. Please continue with your transmissions. Next week I expect to be able to listen regularly.

Hi John, That is it! Your picture shows exactly what I see on 73.3kHz. It is not RTTY but 100Hz wide FSK centred on 73.25. You evidently have a very good antenna for this direction. I would very much

This is really one for the record books! It certainly justifies the retention of 73kHz and even the professionals are probably learning something from it. The chances of making it from ZL to EU havin

Hi Everyone, I have heard OK1DTN regularly during this week. Is this a consequence of improved conditions or is Ruda running high power or perhaps has a better antenna than most? Otherwise the band h
