Hi Dan and all interested parties.
I bought a KA105. I love it, but it's single conversion.
If you are referring to Walter Zhao, President of Kaito
.... I believe he meant 'it works as well as dual conversion'
That was his response to me when I asked the same
question. If someone else answered your question, they
might have mistranslated his response.
The radio had good sensitivity and so so selectivity,
but for a truly *shirt pocket* size digital tuning SW with
direct entry keypad it's awesome. I've had interference
from some minor stations "next door" to the
frequencies I was trying in the 41 M band, and imaging
3 k off the carrier on powerful broadcasters. Definitely
not as good as dual conversion.
I have had it running on two AA batteries on and off
for over 48 hours now (noting the times I listen to it),
and the low battery indicator hasn't shown up. I'll switch to
rechargeables after I finish testing battery life with 2 alkalines.
MW is good, or good enough for me... I get WOAI 1200 kHz in
San Antonio after dark... 960 miles straight line from me. Good
sound for the size, rivals or surpasses my old YB300PE.
FM stereo with the included earbuds is excellent too, with
good separation. Lots of features to like... lock slide button,
light button, sleep timer, a/c adaptor included, wire antenna included,
dual clocks (viewable only when radio is off) and don't forget
direct entry digital tuning!
Again, it is not dual conversion, and selectivity is fair.
But sensitify is excellent for the size and price. I recommend
it if you want a SW you can really carry in your shirt pocket.
P.S. I wasn't thrilled with the strap/tab thing that acts as a
"flip stand". It works... if you don't pick up the radio after
setting on the "stand". If you do, the tab thing drops out and you have to
reposition it.. I ordered the small plastic radio stand from
Universal.

It might "work as a dual conversion" if they used the 10.7 mhz FM IF
transformers as the sw if. I had a Sony once that used that scheme
and it was quite free of images. It would be worth looking into.

Living in the orient gives one a different perspective on these things.
Orientals tend to do literal translations into other languages. In this
case, 'as' most likely means 'like', that's the way it's written in a lot of
stuff over here.

It may a single IF AMP stage. You may not have asked the question
clearly enough. I.E. Not single IF or double IF, but instead ask what
the IF frequencies are. Often enough gain can be produced in a single
IF amp stage behind the RF amplifier, that you only have a mixer for
the second IF frequency, and from their it goes straight to a
detector.

It's been months since someone mentioned the stands from Universal (I've got
several and have had for 5/6 (or so) years.

You wanna give the sales pitch (I don't have the info unpacked yet)?

Thanks,

I kind of think that's what goes on inside my Grundig eTraveller VII.

They might meant "Works as well as a dual conversion radio". That's
possible, if they're compairng a poor dual conversion radio to a good
single conversion one. Dual conversion describes a circuit, not a
desirable performance specification such as adjacent channel
selectivity, image rejection or signal to noise ratio. Back in the
dinosaur radio days, they tried to improve the image rejection of single
conversion radios with more high Q RF sections. That worked but it got
much more expensive with increasing frequency. Double conversion proved
to be the cheaper way.

It seems very unlikely an inexpensive single conversion radio will have
more selectivity or a better image rejection ratio than an inexpensive
double conversion radio. It might have fewer birdies or a lower noise
floor, however.
