Dear LF group,

I have been trying the 'Eclipse' data logging software in preparation 
for group CFH monitoring experiments - it seems to be working 
fine, although I can't get all parts of the eclipse window visible on 
my primitive monitor. Whilst trying it out last night, I noticed there 
seemed to be no CFH on about 137.04kHz where it has been 
transmitting a carrier lately. Conditions seemed quite strange, the 
low level of noise and lack of signals had me checking antenna 
connections, but everything seemed OK. At roughly 2215 a carrier 
appeared at about 136.95, being keyed on and off intermittently 
(CFH station cat loose again?). Eventually it came on as a 
continuous carrier, and was fading out in the usual way when I left 
for work this morning. 

I assume this actually was CFH - they seem to be altering things 
around again. G3NYK's chart on ON7YD's web site shows 
something similar. The SNR looked like a pretty impressive 30dB at 
best on Alan's chart, and this was about what I was seeing too. 
This should easily be good enough for QRSS with 1W ERP, and 
wouldn't have to improve that much for normal CW - we need to get 
some more tests going!

Since today is Friday, I intend to be QRV on 73 kHz again this 
evening, hopefully from 2000 onwards. I will mainly be listening for 
cross-band QSOs on around 137.7kHz. As always, any reports 
would be welcome.

Cheers, Jim Moritz
