Hiya....

I have both the KA-1101 and the KA 1102. I've been using both for over
four months at work to listen to medium wave AM and some short wave. I
switch from one to the other from time to time to see if I can spot any
differences. For the most part, I've found them to be fairly equal not
considering the ssb feature on the 1102. The sensitivity and the audio
quality of both of them is on par. I've found though, that they have some
interesting differences with selectivity. At first, I thought that the
KA1101 was the more selective. I've found that my KA1101 is more selective
then the KA 1102 on the 49 meter band. When I use the KA-1102 to listen to
the BBC on 5975, it gets spooked by what ever is on 5960. The KA 1101 does
not have this problem at that spot.

Today I found another difference between the two in selectivity. This time,
the KA1102 is the better.

I had the KA-1101 tuned to 1190 AM to listen to Air America for a while. It
was being spooked big time by Blumberg Radio on 1130. I could hear 1130
clearly while the KA-1101 was tuned on 1190. I tried both the narrow and
wide filter settings. I still heard 1130 coming through. I even put the
attenuator on "local" and I still heard 1130 spooking 1190

I tried the KA-1102 out on 1190 to see if it suffered from the same intermod
problem. When I tuned the KA-1102 to 1190, I didn't hear 1130 at all.

I am also near the transmitters of several MW powerhouses here in North
Jersey. It is not uncommon for WINS, WBBR, and several other stations to
bleed intermod tens of kilohertz above their actual frequency on cheap
Chinese radios. In fact, on my DE1102 if you tune to shortwave in an area
where there is no signal, you can here the audio of several local MW
transmitters down in the mud. That's why they call if "RF Hell" :-)
