Yes, interesting schematic, I should have started with that.
If you look I forgot the bias resistor from the bfo tranny base to +v, and the 33pf load for the IF filter xtal.
I forgot to add the decoupler on the fet front end, I'll try that, hopefully it wont overload the front end.
The limiter amp distorts on am badly as one might expect, on cw though it works well, theres no audio so it doesnt seem to ruin things.
However the filter amp according to the data sheet is for audio not rf and doesnt limit, your schem shows it as a audio filter but all the gain comes from the following transistor gain stage, I've seen them with a switch for narrowing the passband for cw, I think theres a max suggested o/p voltage I think thats my distortion problem.
I ended up doing pretty much as you would, for am I now have a Ta7642 which does a good job of demodding the rf and has agc, it taps off from the o/p of the IF filter, I have a switch that selects am audio from the '7642 and cw from pin 9 of the '3361.
I've been experimenting tuning a 10.7mc IF trans to 4.43mc and switching it in place of the xtal for wide band a,m.
I'm going to see if i can use the squelch module in the '3361.
