Hello all.

 

After tinkering around for some time I now have a '3 mode beacon' constructed and ready for testing. CW - QRS - PSK31 all on a PICchip.

 

I'm concerned about accidentally putting it on a frequency that is 'occupied' by a station that is operating with crystal control.

 

Is there a list of frequencies to avoid? Or if you are using a crystal perhaps you could just drop me a line and I'll avoid that spot frequency.  I'll  be mainly putting this on overnight and not in peak daytime hours.

 

Thanks
