Help: Noise on SSB from Charger/Inverter
Thanks for reading this message.
Setup: Catamaran 45' ICOM M802 with AT140 tuner, professionally installed, sidestay ant portside Battery Charger/Inverter Mastervolt Dakar Sinus Combi, located in engine room s/board side. My problem, if the Battery charger/Inverter is on, which it normaly is a carrier every 20khz (+ -) with a 60hz humm is audible over the whole HF spectrum. Quite strong so that weak stations are not readable. The noise is picked up via the arial not thru the DC supply. If I disconnect the ant the noise is gone. But just having the ant tuner connected with no ant, the noise is audible. I am looking fwd to some ideas how to get rid of the interference thanks and rgds Wern |

I have the same SSB and tuner, coupled to a Pactor TNC. |
