Hi,


I cant get it to tune into frequencies like 3412 or 3413 or stuff like
that. only stuff like 3415 and 3500 etc. you know only falls on 5's and
10's why wont it go to any 2's or 3's 4's and 6's 7's 8's etc etc?


AM shortwave broadcast stations are spaced at 5kHz intervals so the
receiver was probably designed with that in mind. For simplicity's sake,
they will have used a single loop design in the synthesiser with the
aforementioned 5kHz as the PLL reference frequency. Had the receiver been
meant for sideband/CW operation, it would then have had the ability tune
in smaller increments.

Generally you get what you pay for :-(

But some of these sets did have a 'claifier' or 'fine tune' knob that
pulled the reference rock a little to allow for off frequency stations
and SSB. For ssb you could also just move the BFO a bit too.
The RS rx in question probably doesn't have either of these controls.
