[hpsdr] 50 Volt 300 watt PA from Russia with IMD3 >= 40 dB

[Sid Boyce]

I have the BPF board and Hermes in the ANAN-10 enclosure occupying the 
bottom half and front panel of the larger case.
The 300W PA/LPF board occupies the top half of the case and backpanel 
which has the power inputs, exhaust fan and the antenna connector.

Everything works with cuSDR64 (TX excepted of course). Both the BPF and 
LPF switching work - they work as a clone of ALEX.
I have tried ghpsdr3-alex but it does not support filter switching which 
means no RX signals or LPF connected for TX.

I am waiting for Linux support with cuSDR TX and ghpsdr3-alex filter 
switching.

73 ... Sid.
