RADIOVHF - IC-551 6 meter all mode: Icom IC-551 6 meter all mode in good condition physically. It works fine when used with an external power supply but the internal supply is putting out over 15 volts which the oscillator doesn’t like and won’t fire up correctly. Every other parts seems to work as designed. Output power is a bit over the rated 10 watts. Audio is great. RX is great. Being sold as-is due to the problem with the internal power supply.
More pictures available. Just ask.
