As a logical follow on I opted for a separate Diplexer for my Arrow antenna. I've choosen the WIMO Diplexer #22030.
The HAM RADIO 2018 in Friedrichshafen brought me a new antenna - the Arrow Antennas 146/437-10BP - I plan to use it for SOTA work as well as for working some amateur radio satellites.
Here you find a list of all my SOTA activations
I've made a simple cheat sheet for my HamGadgets Ultra Picokeyer because it is hard to remember the various key sequences and abbreviations in the menu mode :-)

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. |
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.

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.

I was able to get a used 40dB power attenuator from a fellow ham. It is a 250W version in a very good condition. The attenuator should be usable up to 6GHz.
