Angelia SDR and PA rx/tx relay

Postby qst » Sat Aug 12, 2017 7:03 pm

?Hello all,
My Angelia is already working with a hilberling amplifier. But i have problem connecting rx signal to SDR. Herme / Angelia have no tx / rx relay on board. How to make a connection from an external amplifier to the rx socket in the SDR to bring the signal? Do I need to perform an external tx / tx switch?

That is correct, Slawomir, you need to provision a TX/RX switch.

Hi Scott,
Thank you for your answer. Do you know the ready-made factory that will work with my amplifier? I think the switch must be built at the end of the chain and move the full power that the amplifier gives to the antenna. The power output of my PA limits the available solutions.

My apologies, Slawomir, I do not have a good suggestion for you. Perhaps someone else might know?

Hi Scott,
I understand you perfectly. But probably among many of the Hermes SDR users are those who use factory-built external PA ?
