Hello
I will 5W output from sunsdr2 pr0 into eb104.ru VHF PA without attenuator 10 dB >>>>>see file
answer from eb104.ru
Hans, hello!
You should understand that the amplifier in the SunSDR2 has power surges. Need to be careful, these power surges can burn a transistor very easily.
You can remove the attenuator yourself, this is very easy to do. But it will be your risk and your responsibility.

There is no such thing as power surges in SunSDR2 PRO anymore, it was fixed last December - a year ago.
Mic AGC in PROC menu must be always ON and Max amplitude -3 dB, if you use the radio with external PA, use Tune mode for adjusting max PA output power.
