Dear Finbar, thanks fer QSO ur sigs were S9 then dropped to S8. When you went to short Ant. I heard you at S5- S6 equal to my noise but only readability 2 to 3.and then signal dropped again into nois
Test de GW4HXO Hi Michael, Heard you in QSO earlier with GW4UEP and I think GI3PDN. Called you but no reply guess Loop in wrong direction. You were readable at 559.
Hi Dave, NO the top load does reduce the ground resistance ,it also improves the radiation resistance as you suggest, but this is a minor improvement compared to the quite dramatic effect of top load
The problem with an erp limit as low as 0.1W is that there is no incentive to develop better antennas. We can easily develop enough power to drive even the most inefficient of antennas. Not like 136
Hi Vic, Re. Linear Amp, have a look at design by SM0VPO (Ten Watt Linear Amplifier ) just Google, should find it. I use his basic design just put a few more turns on inductors. 73 Hope see you on 500
I am very encouraged by the response to my comments on our erp limit. Regarding ground loss, the best way to reduce this is not to bury wire in the ground but to put it in the air ! 1 metre of wire i
G3UNT has been calling CQ all morning (still calling ) he has a good signal here on the south coast. I am sure he would appreciate a call. Laurie G3AQC
and I'm winding myself up to get involved. I just love the idea of keeping 500kHz alive with hand keyed CW. Will try to get a pre-amp built for the RX loop over the weekend. I suppose a first test wo
John says..............."100mW erp on 500kHz might be pushing from this remote location" Yes I agree, but it would be a challenge, so worthwhile in my opinion. Laurie G3AQC Chichester on the south co
Hi Laurence, Have set up to transmit on 136.319kHz, will be on tonight from 19:45 to 23:45 utc on 136.319 QRSS 60 all being well. Thanks for listening 73 Laurie
Hi Laurence, There is some doubt about 137.699 as a suitable frequency for West/East beacon, see recent mail from Harmut. 136.316 or 136.320 have been suggested as alternatives. Are either of these c
