Marcel, that is excellent work. Just a suggestion to increase the versatility of your design dramatically. As you know, the VCO frequency of the FRG 7 runs from 55 to? 85 mHz with a 55mHz 1st IF. The very common Racal R17 uses the same Wadley loop design, with slightly different VCO frequencies, this one spans 40 to 70 mHz with a 1st IF of 40 mHz.. IF you could find? a little room to program a few extra? bytes into the "megacycle" routine, a keypress perhaps to alter a pointer to a lookup table, this would increase interest enormously..... there are many Wadley loop receivers? out there.that are lacking a good readout, I think interest would be very high. I would buy two without question.

Hi Marcel,

It looks good and I am glad you got it working well. I am looking forward to buying one.

Hi Chris,

Coming back to your question concerning the MHz readout, it seems my proto is working well.

I could stay to the Arduino, but I had to squeeze everything out. I'm now at 99% of the memory.

I also switched to 7 segment characters. I've included some pictures.

Now I can start to design a new PCB. Hope to have it ready within a few months.

Regards, Marcel
