2x frequency counters


I bought these 2x frequency counters from Nelson  VA3NRF in North Bay, to install in my MFJ radio’s for a digital readout

There don’t work right, when I tried to return them and get 2 more that work he ignored me

so if you think you can fix them this could be a great deal only $50 for the pair

they just work but not to the exact frequency  on 146.520 they read 146.5248 & 146.5252 and do not lock on the frequency
