Unfortunately my receiving was rather handicapped
last night...
Normally the brightness for the colour-DF
system is provided by a passive wire antenna, and the auxiliary directional
information is derived from a pair of loops on a second receiver
channel. Occasionally the sound system on my grabber laptop experiences a glitch
which leads to a permanent swap of the left and right stereo channels. This
is quite conspicuous on the grabber when the world of colours "turns upside
down", eg. the strip from SXV Greece at the bottom turns from amber
(southeast) to blue (northwest). Unfortunately the loops suffer
from an about 10 dB higher noise level due to coupling to underground
cables. This then affects the sensitivity of all SpecLab instances,
including the one feeding the opds-32 correlator (but not opds-8 and WSPR which
are run on a separate machine).
Anyhow during this period Joe's Op-32 was detected
at least once, plus a couple of spots from Gus who is really a strong
signal here:

Thanks Markus.

to make OP8 from 32, just divide by 4, right? (8192/4 ms pulses)

And will it be OK to stay on 137.555 as 650 seems a bit
congested?
