RE: LF: LF/MF night and weekend

[Markus Vester <markusvester@aol.com>]

Terry, thanks for those detailed observations! I find the slow spectrogram very helpful.

I used Stefan's sigs as a guide but once again wasn't sure whether to go above or below 478.7. So I ended up trying both and then settled on 478.67 kHz for a while.

 

I had actually noticed that EA5HVK was watching, but apparently "not enuff milliwatts" from this end to make it there in Op-4.

 

Best 73 to all,

 

Markus

Attached my decodes and SL grab for last night.

 

First decode at 18:14 UTC (grayline at English coast). Peak S/N +4 dB. Last decode 05:00 UTC (grayline approximately at HB9). SL still showing a trace at 0700 UTC.

 

First time copy for me (on 477) of  DF6NM, DF2NV. I noticed (on SL) that Marcus changed frequency in the early evening first HF of your signal then LF.

 

I will increase the scroll rate on SL to pick up more detail. There are some interesting blips on the screen that could be other  transmissions too short to see in detail with this scroll rate.

73 Terry GW0EZY – continuing to monitor 477 Op4.

MF!

I just started my TX in OP4 mode on 477 kHz dial. Will run in until sunday evening. BTW the PA was not damaged, it was just a under-dimensioned fuse which i used for the first tests and forgot to replace it by its actual value. Now the transmission should work without interruptions, i hope.

Would be interesting to have some 24 hour monitoring data of the complete saturday, so if you like to take a part in this "study", pse run the RX during that time :-)


Tnx and 73 to all, Stefan/DK7FC
