You are not reading this correctly.
The power displayed on the meter is integrated power in the receive
filter, just as it should be. The computation is accurate to much more
than 0.1 dB irrespective of what the display is doing. But as in all

Paul,
I do not have the D44 and SDR-1000 setup any more since I am using the
FLEX-5000 and the FLEX-3000 primarily in the shack.
I have setup just about every digital mode software package with PowerSDR and I
can say that hands down, WSJT is the most "fickled" and frustrating program of

Hi ALL
This is a test triggered by the S-Meter discussion. I noticed the S-Meter
changes, as should, by changing Bandwidth (BW), assuming white noise.
Predicted amplitude change in dB = 10xlog(BW2/BW1)
e.g. white noise to RX 1 Ant1 RX1 Tap (F5KC, PowerSDR v1.16.1) 10130 KHz CWU
1KHz/100Hz PreAmp
Clay,
I think the code you are looking for is in DttSP/sdr.c in a function called
do_rx_meter. I believe it is already doing what you're wanting though (i.e.
calculating total power within the filter). This is pretty easy to verify
with a two-tone signal generator setup. In my experience, the D
Andy,
I think you'll find the theoretical matches pretty closely with the measured
if you use a stronger input signal. You can even do this within the console
using the Setup Form -> Test Tab set the RX to Noise and vary the filter
width. Use Sig Avg to to take out some of the variance in the me

Actually, it will. There is an option for this in the Setup Form -> Display
Tab called "Show Decimal".

What radio and how do you have the input and output channels configured in the

I have PSDR (1.16.2) talking to DXLab Commander and Winwarbler. WW receives
just fine.
However I am unable to vary the RF level. If I set the drive in PSDR to 100
watts and drop the TX gain to -40 the FWD PWR meter go to about 190 watts out.
And if I set the drive to 35 watts and have the
Somewhat off topic for this list, but we realize many on this list are
also subscribed to the HPSDR list too...
Our website for HPSDR can currently be found at http://hpsdr.info
instead of the usual spot.
The wiki is also there at the hpsdr.info domain.
There may be some links within the web
I figured it out. I had the wrong VAC picked in WW for TX for PSK & RTTY (DUH!)
Works great now.
Thanks!

Since the very first C language version of the sdr, we integrated the
received power in the filter (by summing the bins of the filter and
relying on parseval's relation). This is indeed in do_rx_meter in

Hi Bob,
It's certainly possible that I'm doing this wrong, so let me explain my
procedure and then you can tell me if I'm making a mistake. All of the
following is performed on 6M at 50.200 MHz with a 50 ohm termination
connected to antenna port 1 and the bandwidth set to 500 Hz (mode CWU).
