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

[Arno Imig]

Hi all,

I built the 300 watt PA of "rb.104" with Hermes. It works as promised. The IMD3 is 40dB at 300 watts !!

The PA works very well with Hermes. I am very happy with the PA and can highly recommend it.
I have made the IMD measurement with the Hermes (DUP) and a SDR-1000 at the same time.
On QRZ.Com (DL5AI) some images are intended to measure.

Have fun :-)
