Topband: Diversity-capable transceivers

Hello Barry,

I have been using the 990 for over a year and use it daily on the Low Bands.  I find it an exceptional performer. The ergonomics are not quite as good as the ICOM 7800, but the receiver performance is much better. The capability of the radio is at its best on the low bands, if you look at the ARRL and Sherwood engineering receiver performance figures.

You can set both receivers to track one another, but the second receiver in the 990 is from the Kenwood 590, and is a slightly lower performer, but still very good. I do not use it on diversity. 

I have absolutely no regrets.
