[ICOM] Amp tuning

[AD5VJ Bob]

That would mean that the radio is seeing a match with the amp but if you place an swr meter between the amp and the antenna what do
you read.

I would suspect you will need a tuner between the amp and the antenna to make the output of the amp happy on all bands and
frequencies.

But the tuner must now be able to handle the output wattage of the amp not the radio only.
