As i see, it works great. The best thing is it doesn't influence at all the RF part, not introducing spurs or other noises.

I want to ask if you used some kind of shield and special power decoupling of the module, because about every microcontroller (PIC or AVR) module I used inside a radio caused birdies and other noises at some frequencies on the bands. Once I've got noise from pulses on the LED display signals (because of digit switching). Thanks, 73!

Yes, there is some noise from the muxed display. I wired the display power supply to the dial light switch on the back of the radio, so when the dial lights are off the display is also off. Of course I also lose the freq lock function if I want to hear a weak signal in where there is some LED noise.

Just curios, why didn´t you make the counter in a separate box? that way more leds should be added for a larger display.

Great project indeed.

Hi,

I don't have a practical reason. I like the look with the display in the radio.

73 and thanks for the comment.

Do you have the schematics or will you program the pic? I would love to have this on mine. Did make the circuit board or just bread board. I could not see all that well. Could not you have just used a regular counter chip? I like the design you did a wonderful job.

Really nice job and it looks good to boot.

Thanks for the quick reply, hopefully i will solve the problems in my counter - i think it's because of layout and long connections. 73!

NOW THAT is what real ham radio is. Im not too bad on the building portion and i have a really big respect for the hams who keep the old ways.
