Adjusting S Readings

Post by NA4DX »

How do you adjust the vertical S readings on the right side of the panadapter in PowerSDR. Currently mine show a top reading of S8 which causes a number of signals to peak above the top portion of the panadapter. I would like the S readings to peak in the 20db to 30db over S9 region.

Thanks. de Larry, NA4DX

2 ways:

1) setup->Display->Spectrum Grid->Max = -19, Min=-136 (but it will auto adjust if you check the "auto" wtr/pan checkbox, step = 6

2) move your mouse over the left side dBm scale of the Panadater, LEFT Click (and hold) now drag up/down to adjust the Min. RIGHT Click (and hold) to adjust the Max

remember the S-meter scale on the right side is just for reference because unless you close down your receiver bandpass to 50hz, the SIG S-Meter and the scale will not match. I have a video explanation in my webpage just above the Revision history listing.
