A discussion with Joachim today made me go buy some more kit stuff.
The Rock-mite kits look very suitable for a simple QRSS modification , as seen on Joachim's blog.
I ordered the 80 and 30m versions, one of each.
The best thing is that it is useful as both a grabber receiver and a QRSS MEPT - and the price of $32 a piece to have it sent here should not discourage anyone from doing QRSS.
The Rock-mite is a simple crystal controlled CW transceiver and can be used as such. It is a single frequency device with a crystal as the input filter and another one as (VXO) local oscillator/TX oscillator.
