My QTH is in a suburban high signal environment with powerful broadcast band
stations nearby. I have a 50 KW station on 1010 kc approximately 4 miles to my
WNW, a 10 kw station on 760 kc approximately 5 miles to my NW modulating above
100% and a 5 kw station on 910 kc approximately 2 miles to my WNW.
In this high signal operating environment I have owned an FT-101E, FT-747,
FT-757, FT-840, FT-990 and a TS-830. The FT-747 and FT-757 produced horrendous
signal overload and IMD on 160 meters, suprisingly the FT-990 produced a
moderate amount of signal overload and IMD and BUT the FT-840, FT-101E and
TS-830 produced none.
I am considering buying an FT-1000MP Mark 5 Field and recently borrowed one
to try out at this QTH. It also performed with no overload and IMD on 160. The
FT-1000MP Mark 5 Field will be my main rig, with the FT-840 used as a back up
for the next 160 DX season. It seems that preselection on the front end of a
tranceiver as well as fewer internal RF amps. is a good thing.
