I used an Icom 7800 for diversity reception and found it to be a wonderful
performer. I would listen to my vertical array on 80 while monitoring the same
signals with my second receiver connected to either a Pixel loop or a rotatable
80 dipole.
Now I am back to my trusty FT1000D with dual RX but it doesn't compare to the
7800 due to the disadvantaged 2nd RX in the 1000D. The main RX has all filters
(incl roofing) but the 2nd RX can only do so much as it introduces noise into
the mix degrading any weak signals combined from the main RX.
I hear a lot of DXers speaking highly of the Yaesu FTDX5000 series of radios.
The Sherwood reports seem to think they are among the best "knobbed" XCVRs out
there if you look past the Flex and K3 rig specs. The 5000 , the Icom 78XX
series and the 990 all seem to be great for dual diversity however there are
some real price differentials in the pack.

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.
