Another Kit for 80m QRSS

Maybe the color burst frequency is really the one to go for. Not only cheap crystals, but also kits are available. And here comes the latest thought: Using the "Warbler" with an audio source, e.g. Eddie's XORgan or some software.

Bonus here, when not in transmit, the Warbler can serve as a grabber receiver.
I would however, for QRSS purposes, pull the local oscillator below the crystal filter. The latter should be slightly differently loaded in order to bring the response somewhat to lower frequencies.
