Hello Martin:
I have been using the Icom IC7800 on the TopBand for several years.
Performance is outstanding. True second receiver and incredible diversity
capabilities. Plenty of filtering, audio peak filtering with an extremely
quiet RX.
I worked 103 countries with the IC7800 during the CQ WorldWide CW contest
last weekend on the TopBand.
73,
Tim K3LR

I'd like to understand what makes the K3 "hear" better. What they call
roofing filters are simple 9 mhz Crystal filter know as 1st IF in older
radios. DSP filtering has been around now for years and have certainly
evolved in all radios. Can anyone quote side by side experiences with other
modern radios (like an FT-5000) where the K3 was hearing weak 160 signals
and the other radio was not.
