Hello everyone.
Today I turned on my SunSdr2 pro and I no longer have rx reception on A2?
I tried on A3 and the same no reception? I changed transceiver by plugging in my FT1000 MP and it works so it doesn't come from the antenna.
Do you have any idea of ​​this failure?
And it repairable?
I have not touched the setting of the software that I have been using for 2 years.
We had a thunderstorm 3 days ago in the night, the device turned off, antenna connected to the amplifier and Sunsdr2 Pro connected to the amplifier.
Thank you for your answers.

Maybe a relays-

But you mentioned antennas connected and radio connected during a thunderstorm
My initial gut response is: the FRONT END of the radio has been damaged or blown due to static discharge,

What about VHF?

I try very hard to always disconnect antennas in shack If the radio isn't on it is disconnected, even a close nearby discharge without ant connected have taken out rigs and equip before coming through power connectors

Its also why I need to get off my ass and finish building the automatic disconnect for power/ant - that is tied to the weather station lighting detector- for controlling the relays to disconnect upon detection.

You're probably going to have to have it serviced

Hello Rick, thank you for your comment. I just tested this morning, I also have the Sunsdr2 DX and I plugged it in instead of the Sunsdr2 pro and I have the same result.
So I figured there was something wrong.
I changed the mini din cord and indeed it works, yessss. :yahoo:
The original cord has dropped. :shock:
So everything is back to normal. 8-)
Looking forward to contacting you on 20 m because I am very active.
Best 73 Patrick F8BNU.
