I'm not familiar with the problem, but I wonder if summing
the 2 audio outputs would still work. I noticed when combining music
stereo sources that the noise significantly reduces.

the only FT1000 with diversity that I
am aware off is a modified FT1000D where a modification adds a relay and
enables the source for LO on the second receiver to be switched to the first
It is bad enough having the two
diversity channels moving around in ones head, the last thing you want is the
phase of the second LO drifting when compared to the main channel

[CrossCountryWireless] SDR-4++ dual diversity SDR receiver
Previously I was looking at
transceivers that allowed receive diversity.
If I remember correctly the only
ones that phase locked the receivers were the Elecraft K3, Flex 5000 (with 2nd
RX option installed) and the Flex 6700.
The Yaesu FT1000MP (all of
them), FT2000, FT DX5000 and the TenTec Orion and Orion II allowed stereo
receive but their receivers weren't phase locked. I saw a mod for the TenTec
Orion to phase lock the receivers but since the the 2nd receiver wasn't
identical in performance to the 1st the results were not as good as it could
be. Tentec released an update to the 2nd receiver so it performance matched
the first but I never found any info on the web about having both
modifications at the same time.
I was looking for a Flex 5000
with the 2nd RX installed, but ended up getting a Flex 6300. Receive diversity
is the only feature missing that I looking for in a new transceiver. The Flex
6700 was way out my price range.
