Dear Ed, LF Group,

I checked all the screen shots taken from 1400 - 2200utc, but unfortunately
no recognisable signals from RU6LA in the 136kHz band were detectable.
CT1DRP was visible at the beginning and end of the period, also a quite
strong but unidentified signal just above 136.318kHz appeared a couple of
times. The QRN level was quite high after about 1700 here. I was able to
copy all the HF signals from RU6LA, check the frequencies, and set the LF RX
frequency accordingly, so I'm confident if there was a signal to be seen, it
would have been on the screen. So, for the time being at least, it seems the
best way of transmitting a signal on 136k is to use an LF transmitter :-)
Thanks for running an interesting experiment,

Cheers, Jim Moritz
