First succsess on 23cm
Posted: Sat Jun 12, 2021 2:26 pm
Today I had the first success with the Langstone TRX on 23cm.
Some time ago I bought two amplifiers for 23 + 13cm from SG-Lab. The interesting thing is that you can switch an optional RX output there and thus have separate outputs for TX and RX. In addition, the amplifier has a 16dB LNA with a band pass filter in front of it.
However, the 16dB is not enough for the Pluto. You have to amplify a little with a broadband LNA in front of Pluto.
In any case, I can work a few 23cm FM repeaters here and the modulation of the Langstone sounds very great.
I have attached my current concept here.
To everyone a nice weekend
