Well, it all depends on the level of audio input and will need some experimentation. The one thing I can say for certain is the 'AGC' setting is far from optimum and not advised, especially when ther
I do not believe that a two-way QSO resulted from last night's activity. However, HE3OM was visible at good strength on JA7NI's QRSS30 grabber, but with deep QSB, for five or six hours. UA4WPF was al
I shall be transmitting overnight on 136.1770 from 1900 to 0900UTC. Text is 'XDV', QRSS60, starting on each hour. Thanks in advance for grabbers, reports etc. Mike, G3XDV ==
There was no =change= from 136.318kHz to 136.177kHz. The latter frequency was suggested as an alternative to fix a problem on a particular path, and most stations went along with it. Many grabbers ar
I will be sending 'X' in QRSS120 early evening, then 'XDV' in QRSS60 overnight on the hour from 1900 to 0900UTC. Frequency is 136.17775kHz. Reports welcome as ever. Good to see that beaconing for gra
I think you are experiencing voltage leakage (the equivalent of adding resistance). An LF antenna has very high voltage on it, especially if (as I suspect) your antenna is very short, even at quite l
You may need an external pre-amp. See several books and web sites for circuits. Your insulation should not be a problem on receive. I forgot to mention that I get some advantage from driving Argo ve
Last night HE3OM put a good signal into JA7NI's grabber at JA dawn.. UA4WPF can also be seen, but much weaker than previously. See attached. Also attached is the same time on RN3AGC's grabber which s
Big audible signal transmiting 'FMT' on 137.460kHz using QRSS10 and rather wobbly frequency. Pic attached showing signal with and without my 10dB attenuator in circuit. Mike, G3XDV == The following s
Toni, Unfortunately, this will only be effective if you can get JA7NI to alter his Argo to QRSS30 as well. His current setting is '90s slow speed' which is about right for QRSS120. If you can't get t
I have been off 137kHz for a few weeks whilst playing with UHF (well, topband actually). Amazingly my antenna (12m vertical and 5 x 13m horizntal) resonated exactly on 1830kHz. Interestingly, the ear
Chris, Please see the attached three files with Argo set to QRSS3, 10 and 20. I can't hear you but a QRSS3 QSO would be easy. Incidentally, you can see from these pictures the effect on SNR of changi
I shall be running an experimental beacon on 136.17775 overnight. QRSS60, 'XDV' sent each hour starting on the hour,from 1600 to 0900UTC. Mike, G3XDV ==
I will be running my experimental beacon overnight on 136.17775kHz transmitting 'XDV' using QRSS60 from 1900 to 0900UTC, starting on each hour. Until 1830 I will be sending 'X' on QRSS120 on that fre
Yes, Stefan's sigs very good this morning (see attached). Fist time I have successfully received him. Mike, G3XDV == The following section of this message contains a file attachment prepared for tra
Receive set-up: IC706 plus pre-amp; transmit antenna (inverted-L, 12m vertical, 5x13m horizontal, tuned against earth stakes). I am also some 20% closer to Chris than you are, which helps. MIke ==
