i bought a chinese amazon autotuner. worked great till it didnt. replaced it and its all good. but back to the one that dont work.
powers up, self tests, 9.99 swr in bypass, auto will not tune. it goes into tune and just locks up. will reset. checked diodes under swr bridge and they seem ok. dont see any worser than usual solder joints. i prob fried it hooking it up backwards or lightening, who knows. had a yeasu front end diode pop around that time too. any ideas?
