We gave the ICOM 802 SSB a test or two on the Pacific Seafarers net 1430 and tried it with the antenna tuner off (THRU) And then on (TUNE). It id did seem to make much difference.
We disconnected the reefer and shore power plug. We were still in the marina and I did not change anything else. Perhaps if I went through the manual and tried some different settings we could hear better. We did pick up some one from Hawaii and even further away but am not sure.
Not sure about privacy issues here but there was not much said that could be private.
We will keep trying and see how it goes.
The next day we got the ICOM 802 SSB receiving the GPS data with time and location from our chart plotter.
