I have a S350 and it's my "sitting on the back porch with a beer on a nice
night radio", but it's no DX machine. The S350 is a single conversion
radio
and it suffers badly from images as a result.


Just to pick nits, there were many single conversion radios which had decent
image rejection due to additional stages of RF amplification and tuned
circuits. The dual conversion approach became cheaper way to a high
performance radio sometime around 1950. However, multiconversion radios
will have an extra image for each conversion, not to mention conversion
oscillator fundamental and harmonic and IF harmonic birdies. These should
be well supressed, but it's entirely possible some schlockmeister will come
up with a really cheap multiconversion radio that's a total nightmare.

You're right. I guess when ever I get images on my S350 I just
automatically blame it on its single-conversion design mostly because I have
a cheap Tecsun that's double-conversion and much better at fighting off
images. Perhaps some of the image problems on the S350 can also be blamed
on its filters. They are extra-crappy.
