High 1st IFs like 55.845 MHz aren't quite uncritical, particularly with
very compact receivers

That's high? ;)

My radio's first IF is 240.1 MHZ.

you easily get leakage around the 1st IF
crystal filter.

Good information. I didn't know that before.

And just the other year or so, I didn't know anything about IF frequencies or
radio image frequencies.

I still don't know much about them.

Is it still worth it to get a CW/RTTY decoder which are still advertised
in
magazines such as "Popular Communications" and "Monitoring Times"?



I don't do utility listening, and I can't offer a useful opinion on
decoders. It might be worth starting a new thread with your question.
