Power/swr meter with "openhpsdr transceiver" frmwr

Beitrag von f6itu » Do Jan 03, 2019 6:06 pm


Hi

Amongst the many way PowerSDR mRX manages the forward and reflected power display, one consists using 2 analog input (plugged to a so called "commodity ADC on HPSDR hardware), those two lines comming from the FWD and REV power voltages delivered by a simple VSWR tandem bridge.
I'd like to know if such a possibility has been considered in Pavel's firmware (using for example analog inputs available on E2 connector)

Cheers

Thank you, Siegfried and Yevgueni

I was just remembering something like that, but couldn't retreive this info.

I'll try to add some buffering or limitation (Zener ? ) to avoid killing the gpio. Thanks again to both of you, you make my day :- DD

I've probably read more than 100 times Pavel's notes... how could I have missed this. Or, worst, refuse to see it.
"slow analog inputs can be used for the forward (Analog input 0) and reverse (Analog input 1) power measurement"

I really feel ashame not Reading The Fucking Manual

Really
Marc
