It is amazing to believe that this design of mine is 10 years old! These days, many have gone on to FT8 instead, but there is a good following on 10m WSPR as well. This used very low cost 14.060 MHz crystals that were pulled, making this a very low cost design. It worked well.
Also, if you use a 14.040 MHz crystal pulled down a bit, this should be useful for FT8 monitoring. I have one or two of those crystals, and I might try it out.
ReplyDeleteBTW the build in the picture looks very neat.

Hi Jan - my circuit for FT8 using this circuit was in RadCom. I can confirm it really works well!
