Caveat, the 870 will still experience IMD3 problems, in very crowded band
conditions with mega loud signals, even if the so called AIP ( advanced
intercept point) is enabled. However, about 6dB of attenuation always seems
to knock it out on the very rare occasions it has troubled me. I tolerate
this, because it is simply the best transceiver I have ever used. The in
band ( i.e. within filter ) IMD performance is second to none ( see ARRL
expanded review) and this is largely what makes it such a delight to
use-i.e. sounds really quiet. The choice of 2,4,6,8mS rise and fall times
for keying, makes it a really super sounding rig too. QSK works FB although
is a tad noisy, for those young enough still to have good HF audio ears
I recently got an IC7400, ostensibly for 6m and 2m, and as a back up HF rig.
This is also shaping up very well indeed as a contest rig. The DSP filtering
goes a step beyond even the 870 which is really very good, with brick wall
edges to the filters.The menu system is far superior to Yaesu and Kenwood,
which are rather impenetrable I feel. Also the twin PBT got me out of jail a
couple of times in IARU, when G9BF decided to park on my bows.I retired my
FT1000MP a while back, as I just don't see it as a CW man's rig, and I don't
need dual receivers ( use dual rigs!), one of which is pretty crummy anyway.
Please don't let on about the 870, as the price is pretty depressed, which
is where it should stay!
