I use a Windows10 PC (6-core 3.4GHz AMD 3 + 16GB RAM + CUDA video card). 

The used software is SDRconsole. I like this software for Windows, but find it confusing to learn.

My Hermes Lite2 and this PC are connected to the local area network using a TL-SG105 Gigabit switch.

About 1W output from the HL2 drives the PA to clean 400W SSB. When whistling, a max. output power of 600W peak could be noted.

To prevent damaging to the PA, and an optimal working VSWR indicator in the HL2, a 6dB/5W attenuator and 4 to 5W drive should be used.

Three cheap cylindrical 2W SMA attenuators connected in series can do the job. The first will then dissipate abt. 2W, the other two less, and both HL2 output and PA input will see more resistive 50 Ohms impedance.


The complete 400W radio system :
50V 25A Power Supply, and on top of the PA : HL2 + Gigabit switch.
Two network cables to router and PC.

My actual screen in SDR-console.

The buttons at the top of the SDR-radio site spectrum pictures do not exist on my SDRconsole screen. I cannot activate Pure Signal.

At this moment (202103), Pure Signal seems not to be working in SDRconsole.
