QO-100 antenna reduce and setup upgrade...

Uninstalling the 1.5m dish (that was too big for NB) I install a brand new 80cm dish with the same POTY feed. Thanks George SV5KJO for donation.

New setup with ADALM Pluto SDR for RX-TX and an x-commercial Power Amplifier. A needed 12v to 28v step-up converter for PA and a step-down converter 12v to 5v for PLUTO and midrange preamplifier. Thanks to my good friend Tom SP5XMU for power amplifier...!!!

Testing the Band-Pass 2.4 GHz filter, power drop-down...

Tuning the step-up converter for 28v....
