Dear LF Group,

I had to give "my" cherry-picker back to it's true owner over the weekend, who needs it for work for an indefinite period. So unfortunately I am now without my high antenna support, until I can devise a suitable sky-hook that won't attract the attention of the local planning department. The extra height is worth several dB on the transmitted signal at 73k, so for this reason, I did not think it worthwhile running my 73kHz beacon signal over the weekend. However, I Hope to be QRV tomorrow morning, and the signal level I can get should be OK for the daytime noise level. I have to go to work eventually, so will start around 0700. If Rugby is operating, about 71.65 is the best frequency for aural CW, as the noise is lowest there. Assuming Rugby has shut down, I will move up the band to 72kHz or so.

As far as X-band contacts to 136kHz are concerned, I can switch between 73k and 136k receive quite quickly to listen for replies. Perhaps 137.2kHz or thereabouts would be better than 136.5, because there will probably be fewer people trying to have 136kHz QSOs on that frequency - in my experience, it can result in confusion when someone is calling on 136.5, but cannot hear a station replying on the same frequency. But that's just an idea.

Cheers, Jim Moritz
