Heavy rain so I have had to postpone further 73kHz antenna tests for the time being. I will be transmitting on 137.3+ tonight (Sat) and tomorrow for QRSS contacts. Regards, Peter, G3LDO Web <http://w
No. Sorry if I was unclear. I have three top wires, 18m long, running parallel and spaced 0.5m apart. The wires have always been joined at the far end, and this helps reduce the corona losses. I also
First of all congratulations to Jim and John for another 'first'. Congrats also Alberto and Vittorio for their excellent S/W and its success in this experiment. I am still plugging away at trying to
The weather in the last few days has been very wet and the lawn is saturated. The maximum antenna current is 3 amps and that is after I have adjusted to matching transformer to try and compensate fo
I had reported earlier that my antenna current varies considerably for reasons that I don't understand. Last week, during a session of 73kHz T/A tests the weather was very cold and dry with a moderat
During my first cross-band QSO with VE1ZJ in September 2000 I was unsure what to send - in the end I sent all the call signs TNX and 73s - the lot. However conditions where good and with 3 second dot
I agree with Peter, Dex's information is very useful,and certainly 73 appears very stable. However it is still dependant on solar conditions,at the moment Kp is very low but it is unlikely to remain
Dexter, your HBG plot is most interesting and shows a greater stability of signal strength over the night period than on 136kHz. This implies that a cross-band QSO/HF would be possible even with the
That was quite an exciting night. Started transmitting at 2200 on Tuesday night and later was getting reports from John and Dex through their website postings. I decided to go to bed at 0100 and went
I completed the move of my best receive loop to hopefully a quieter location. It is now about 100 meters from the house. I am still receiving QRN from a few storms about 500 km to my south east. Howe
Hi Alberto I got round to downloading Argo 131 at last but I when I start up I get the message " is not a valid integer The screen display is then shown and when a signal is input to the soundcard th
Received G3LDO with a fairly good signal, especially considering that the antenna was the dipole for 80m, absolutely untuned on 73 kHz. Screen capture attached. Thanks for the report Alberto. k inde
John's recordings show the usual after midnight fade. I have just been down to the transmitting shed and all looks OK except that the antenna current is down. I am not sure what causes the variation
Thanks to John and Dex for monitoring the signal frequency. I am shutting the transmitter down now at 0100. Will be on at around 0515 to test the enviorionment theory. Regards, Peter, G3LDO Web <http
John & Dexter My! that's quick feedback. My frequency counter says 72.40043 John's recordings show the usual after midnight fade. I have just been down to the transmitting shed and all looks OK excep
Hi John, I was a little late in starting, but I'm posting screen captures of 72.400 - 72.401 every 15 minutes, starting at 2335 UTC. There appears to be a signal at 72.4004. I have a Loran line at 72
kp index low I will switch 73kHz tx on 72.4003, QRSS120, for a couple of hours starting now 2215 Regards, Peter, G3LDO Web <http://web.ukonline.co.uk/g3ldo>
Back in business again, thanks to GI1PHF, who got the bits PDQ. Only one device had popped, ..... The fix worked well. We had a QSO at 1630 today on 71.7kHz. Ians's signal shown in the attachment (i
I have just had the shack/office redecorated and carpeted (luxury at last). During this time all the computer and ham radio gear had to be dismantled although I did manage a contact on 73kHz from the
Started sending QRSS3 at 0800 but had to close down at 0820 because I had to go out. When I came back the contractor was here to do some work in the shack/office (I had forgotten about that) so was n
