SOTA - DM/BW-078 - Römerstein

Our third SOTA activation for 2018 is done. Monika (DL6SCF), our daugther Lisa and I activated the Römerstein DM/BW-078. Beautiful weather, a little bit overcast and not too warm. The CONDX where better than last sunday.

SOTA - DM/BW-855 - Michelsberg

 Our second SOTA activation for 2018 is done. Monika (DL6SCF) and I activated the "Michelsberg" DM/BW-855. Beautiful weather - very sunny but not too warm. The CONDX where horrible. Deep QSB from S0 up to S9 from Spain und into the UK - very frustrating.

RF Powermeter - Precision V2

As described here, I've build an RF Powermeter.

After aquiring an HF signal generator, a used HP 8647A, I started to do some testing regarding the precision of the RF powermeter.
