Adjusting a self-build 145mhz, 600kc shift cavity filter.
For the repeater in Almere in the 2meter band and dstar on the same frequency 145.7625mhz.
Removed from the air in October 2018 due to no interest in this repeater.
Reconstructed to the design of PA0NHC.

A pre-amp is required to improve the reception.

A lot of work has been done to recreate this filter, but fun to do.

Does work perfect!
