I left the 10m TX for a while and got started building a simple 30m direct conversion QRSS reveiver.
Discussions with Joachim resulted in two receivers one already built by Joachim and the one I am building now, with a local oscillator at half the RX frequency and using a RA3AAE type mixer
For this RX I am generally following this concept found at PA2OHH, the difference is that I - like Joachim - use a canned oscillator at 5.0688 MHz
The Oscillator/mixer and the AF circuit is ready for an initial test (tomorrow), and the RF input circuit is yet missing.
Lesotho in the log on 28 MHz CW - 27th March 2024

I managed to work the *7P8EI* in Lesotho today on 28 MHz CW, my first DX
contact in about 12-months!
I have no idea if it's a new country or not on 28 MH...
