I have the 1101 and the 1103. The 1103 has much richer audio, SSB
and the ability to off tune a frequency to get away from interference.
The 1101 tune SW in 5kHz steps.
The only thing I can think of that the 1101 is better at is in
battery consumption. It is very easy on batteries while the 1103 chews
thru them in short order.

Does the 1101 use 3 batteries or 4?

I solved - or at least minimized the impact of the 1103 tending to go
through batteries.

I've found a wallwart charger and two sets of NIMH batteries to be a
flexible solution. I can get about 2.5 weeks of listening about 1-2
hours a day from a charge.

John: The 1101 uses three batteries and as I mentioned they last a
long time. I have discovered, however , that the top battery seems to
run down about twice as fast as the two that lie further down. Every
time the radio quits I find that the two good batteries are only 1/2
exhausted. The third battery is dead. Generally I find a half dead
battery and pop it in and I'm good to go for a long time.
I did the same as you with regards to the 1103. I got some
Energizer 2500 ma nimh batteries and they do me for about a month of
erratic useage ( maybe an hour a day, I am not certain). I didn't
time the alkalines I used the first time but I checked them on the
multimeter before I inserted them and then checked again after about 5
hours use and found that they were down significantly.
I have used the Kaito supplied AC adapter and it works OK for
MW and some of the ham bands but introduces a hum on the 9 mHz band.
It also allows noise from the powerlines into the radio and markedly
increases background noise.
