how about a cross band QSO 73/136 in Slow CW.
73 de Toni, HB9ASB


Ho Toni.

I would love to, but I think we have a better chance later in the year for the following reasons:

1) I have been plotting the signal from HBG using ON5OO's excellent software, and it confirms what I had from casual observation. That is an 8-10dB enhancement when the path is in darkness. I will post some of these shortly on my web site. At present, either we must get up very early or battle with QRN at night.

2) There are several improvements to be made to my antenna system which will give me a greater effective height and bigger capacitance hat. Both of these will have a greater effect on 73 than 136.

3) My 73kHz erp at present is around 23mW, compared to about 140mW on 136 so we will need all the help we can get.

Suggest we take another look at a sked around late September.

By the way, I will be doing some serious 73kHz work from west Wales in October, hoping to beat the two-way record which is about 180km at present. I expect to have a really stable oscillator (wow!) and will be able to send QRSs from a portable site in GW. A one-way to you, or a two-way cross-band would really be one for the record books at 1000km+, and very difficult to beat in the few months we still have the band (ends in June 2000). I have heard you on 136 from GW so that bit is easy!!!

By the way, I failed to get my report last time we worked on 136kHz normal CW so would appreciate a call next time you hear me.
