Hi all, CFH was active last night, but due to the solstice there is a fairly
narrow "window". I have not calibrated the receiver for some time and this
needs a check, but there is a distinct jump in the average noise level at
about 0700z, well after CFH faded out, which would seem to tally with
Laurie's plot of the lines appearing. I am surprised that the effect is so
small, but it may indicate that my local noises have increased substantially
over the last 2 years or so. The rx IF output (455kHz) is measured on a B&K
wideband millivoltmeter set to "average". The bandwidth of the IF filter is
300Hz.
The plot is posted to my propagation report page at
