>The problem with the QST review is that after the comment about the
multimode transciever the reviewer goes on to talk about repeater
offsets, nonstandard splits, CTCSS encode/decode, and other FM stuff,
and says not a word about the rig's weak signal VHF/UHF performance.  I
did not find anything in this review that would make me interested in it
as a VHF+ rig, but it looks like a nice HF portable.

>Bruce WW1M

The QST review discussion of the IC-7000 focused mostly on HF, as Bruce 
notes. The commentary regarding the radio's performance on VHF/UHF weak 
signal SSB/CW was cursory.  You have to dig to find the IC-7000's weak 
signal VHF/UHF performance in the "Receiver Dynamic Testing" table on page 
66.

For example with 10 dB (S+N/N) 1-kHz tone 30% mod:

50 MHz      1.0 uV preamp off     0.48 uV preamp on.

144 MHz    1.4 uV preamp off     0.45 uV preamp on.

432 MHz    1.6uV preamp off      0.5 uV preamp on.

Receiver and transmitter Dynamic Testing, IMD and power output on VHF/UHF 
are detailed in the review's tables. How these compare with other multimode 
HF + VHF/UHF radios was not discussed, but you can do your own comparison by 
using these numbers.

The original IC-706 review appeared in March 1996 QST, IC-706MII review in 
March 1998, the IC-706MII(G) in July 1999 and the IC-756PROIII in March, 
2005.
