LF/VLF,
Very low noise today on LF and VLF.
Ossi/OE5ODL is QRV again, today on 8970.05 Hz, with the characteristic
drift. A good ID :-)
Just found some time to build a LF preamp for the ferrite antenna. Maybe
someone has fun and time to make some acty on 137.7 in a hour or so?
Would like to compare signal levels and S/N of both, the 50 Ohm preamp
and the high-Z preamp in a quiet location.
Screenshots will be posted here...
Best 73, Stefan/DK7FC
PS: Will run a QRSS-3 beacon on 137.730 kHz, using 0 V PA supply voltage
(i.e. no supply). There is a weak signal anyway, just because the FETs
gets switched! This signal is visible at DF6NM in the QRSS-60 window in
174 km distance! ;-)
