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.
QRP-LABS 5Watt PA - I am still struggling to make a "simple" 5Watt PA for the 1.8 - 50MHz range The QRP-LABS 5W PA could not deliver more then 1W at 28MHz using the original...
