The first preamplifier is a K2AH type and the second stage a
single MGF1302, with this combination I reach a .25dB NF.
At the moment, I have 30W at the feed, but a four 2C39 tube power
amplifier (air cooled) is close to be ready.
The measured sun noise is always close to 20 dB and I hear my
own echoes on CW and SSB, running 30W.
