Laurie, I will definitely be listening on 71.9215 kHz on Saturday night/ Sunday morning. This will be from Maine (FN43sv), not my usual Massachusetts (FN42ch) QTH. Can't do anything tonight, however.

Hello Mal, What I have been saying all the time and I am glad you and others realize this at LAST!!!! I (and probably all the others) have been understanding this all the time. It doesn't change anyt
Hi Alberto, If an short vertical monopole is placed over perfect ground and brought to resonance with a perfect loadingcoil there are no losses, so its performance will be independent of its length.
Rik, thanks for the explanations. I would have never imagined that the gain provided by having a radiation diagram 'squeezed' in the vertical plane could more than compensate for the losses caused by
[...] A short vertical monopole has a gain of 4.77dBi / 2.62dBd because of its radiation pattern, especially the rather 'sharp' vertical pattern. This gain of 4.77dBi assumes a perfect ground, so no

[...] The gain of a short vertical is 4.77dBi or 2.62dBd. [...] Hi Rik and the group, maybe today I am denser than the usual, but, how can a short vertical monopole have a gain when compared to a di
Just caught up with the excellent work this last week - well done to Laurie and John in particular, but also the others in NA who were receiving and the guys in UK transmitting. It makes our efforts
Laurie, Well I have achieved what I set out to do,so would be happy to stop the beacon now if anyone wants to have a go. But I am aware that there are others who were looking for my signal, Dex for e
Why not use DFCW like the ZL's, that way both elements are the same short length? VE7SL / Steve Thanks John, I will go for the complete call now (dont want any criticism !) Would it not be better to

Congratulations John and Laurie. I have been watching Laurie's 72 KHz signal also. Last night I saw nothing. On previous nights several times I saw a 120 second line on 72.4014 (dash frequency) but I
Well done guys! John, G4CNN I did copy Laurie's 72.401 kHz transmission last night, with parts of and without recognizable characters. The best copy was from 0022-0052 and from 0452-0522 Z. For some
Laurie, Thanks John, I will go for the complete call now (dont want any criticism !) Would it not be better to use 90 or even 120sec Argo at your end to ensure maximum SNR.Alternately I could shorten

David, Errr, don't you need a complete call for a 'world record' ? However, that must be just a matter of a few more nights. Not a bad point. Conditions were such that a full call sign should have be

Dear John, Laurie, LF group, Congratulations on this new Transatlantic crossing - looks like your perseverance has finally paid off! Cheers, Jim Moritz 73 de M0BMU
