Re: LF: Strong TA-Signals

Hi Joe, LF,

Signals were not so strong  (S/N) here. This is the best image from last night: https://dl.dropboxusercontent.com/u/19882028/LF/TA60_29.DEC_07.40UTC.jpg

BUT: I've prepared some high Q pot cores to improve my LF RX, see https://dl.dropboxusercontent.com/u/19882028/LF/LF%20RX%20pot%20cores.jpg
Q is above 500. That will help a bit. Another step is in preparation, a series configuration of band filters for LF and MF in front of the first FET. That could help even more, also on MF (due to AFN and DLF).

Hartmut, most impressive, as usual!

 

Here I got a fat signal from VO1NA again, and at least partly readable traces from WD2XGJ and WE2XEB (see "screenshots last 24 h" link at the bottom of my grabber).

 

In the µHz spectrogram, there is are also weak blue trace on 137777.58 Hz probably caused by WD2XKO, and some activity near 137779.0 likely from WD2XES's DFCW.

 

Thanks all for transmitting, it's a pleasure to be treated with such a bounty of signals!
