Hello Andy2,

as I dont know the circuit, it could be possible.
Is this a known problem, when getting DC to the Input?
I remember, the RSP1a was running about 10 minutes without any problem.
Maybe I have touched the BiasT button.
This would be easy to discover, when knowing the coil, unsolder it, and receive would maybe back. If there is not more broken.
But I dont know where it is.
Do you have an idea?

I did a support ticket, but they dont answer. Nevertheless, a service-repair would’nt make sense, because shipping EU <> US is too expensive.
Only way is to repair it myself, but without idea of the circuit, difficult. Will look at the PCB again…
Thank you, sdrx
