[hpsdr] Getting PowerSDR to display SWR

[Phil Harman]

Hi John,

Your correct, we did look at this before.  From memory the issues is that there is a delay between the FWD and REV samples that means for  other than a steady carrier the SWR reading is meaningless.  I think this was a problem with the Flex hardware but not sure if we will have the same problem.

The solution may be to calculate the SWR in the FPGA on Penny(Lane) since that will have the least sample delays.

HPSDR, 

I am sure this has been discussed before - but I can't seem to find it in the archives.

Is there a way to get PowerSDR to display SWR on the TX Meter?  In the configuration settings there is a box to pick for this - but when you run there is not a way to select SWR.  
Reflected Power is there - but not SWR.

Thanks in Advance.

73's,
