Did you try the V7A with AIP on? I have a G707 (very similar RF
construction IIRC) & found it's performance similar: very sensitive RX but
horrible IMD performance: spur free dynamic range with AIP off is only 61
dB, which is on par with some of my HTs. Turning on AIP raises it to ~70
dB while only losing maybe 3 dB of sensitivity, which is OK but my
FT-8500's SFDR is a couple dB better than that.
It does make for a nice travel radio, since when I get out of the metro
areas I can turn AIP off & get maximum sensitivity where I need it, in the
middle of nowhere. I just wish AIP had more effect. & of course I wish it
did "split tone" (different CTCSS encode/decode tones, not Yaesu's
incorrect definition).
Speaking of which, I look with despair at Yaesu's newest offering, the
FT-1802, which STILL doesn't have split tone. We need more complaints sent
into the "big 3" about this.
