I've been meaning to experiment with the Arduino I've had around for years. A couple of hours of dinking around and downloading libs and I've got a functional programmable keyer that I can set into "low power mode" (uA?) . Nice! The keying string is almost infinite in length if needed and given that it's programmable, it can be buried in loops in loops in loops giveing a variety of messages, etc. Cool!

Oh, the best part? Buying from banggood.com or similar outfits, the mini versions of the arduino are less than three dollars DELIVERED in the US.  Yes, I'll have to hang a single transistor on the output to key a transmitter but that's not any sort of problem.

I'm hearing a slow dasher on 7.98Mhz. Dunno if it's new or an old reactivated. Short dash, long quiet interval.

Anyone else hr it?

Hearing faint dasher on 7997.6 .... did the one just above this one drift down?

Stronger now. This one has very slow rep rate...about once every 4 seconds.

copying QRP on 8.000.2 quite nicely (22:36) on a rotary dipole pointed in the right direction.  Nice copy still.
