Dear Andy, LF Group,

The SNR for your beacon received here is up by 3-4dB, so in line with 
expectations.

My dummy load behaves in the same way - it may be the same as you have, it 
is a Bird Tenuline model 8327. So whatever its virtues, temperature 
stability does not seem to be one of them!
