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.

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!

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.
