You can easily get a notch if you have the RX Equalizer engaged without
intending to have it engaged. Click on the equalizer tab and make sure
they are NOT checked.

Hi Bob Eric.
OK. Here is what I did, just now to verify the reduced power with
Preview 8. I was really careful about making sure nothing was different
between the two setups.
Using a database from Preview 7, I did a Reset All to reset the DB
back to defaults. I re-ran the PA calibration.

This will likely be the last release of the year. It has been an
exciting year and we look forward to more excitement in the year to
come. On behalf of everyone here at FlexRadio Systems,
Eric, what a wonderful gift for the holidays! Thank you very much.
Wishing everyone a very Merry Christmas and a Happy Hanukkah.

Eric,
With Preview 9 in SSB mode, as soon as I modulate the signal in SSB
(upper and lower) and DigiU modes I immediately get a white box outlined
with a red line and a red cross in the middle. I also get an unhandled
exception:

Same here. I was going to run this version without importing a previous
database but I could not get the calibration routine to get past 160
meters. I imported the database from preview 8 so I could run more
tests. I only get the white screen with the red X in the DigU and DigL
modes. In
To Eric, Bob and all those working hard to
bring us the SDR1000.
Thanks for Preview 9 I have it working well on Digi
modes with Mixw and now VAC 3.11, I'll see how that goes.
Thanks for all your efforts to bring us the radio

Loaded P9 here. Installed OK, but when I went to setup in immediately
locked up. I imported DB from P8. I tried running FFTW_WISDOM again in
P9 directory. The program comes up, but if you click on anything,
including the Standby button, it locks up.

I was able to resolve my problem by:
1.) Deleting the database and allowing PowerSDR to create a new one.
2.) Run the Freq. Calibration, RX Image Rejection (from a freq.
Generator) and Level Calibration
3.) Run the PA Gain calibration.
Go figure?
The only anomaly I saw was that the RX Image

Starting with a clean DB and running all of the calibration routines
seemed to do the trick.

Ooops. That is a problem. I suspect that is a floating/double

Thanks Eric for your reply. Would be very nice to control the SDR1k via
touchscreen so I'll wait and for future power-sdr releases.
Leon,
I own sdr1k for 6 month now and I never had unwanted keydown or something
strange happening. My Pc and sdr are running 24h a day and even when

Hello,
I started with a new database and beta 9 works fine here until I switched
the transmit-equalizer on: Error message appears with overflow error and I
got red cross on white ground in the scope window. Then I have to restart
power-sdr and switch transmit equalizer off. Then everything works
Sigh. This is not an overnight fix. The IIR filters were right on the
hairy edge, barely working right before. Moving from double
precision to single pushed it over the edge into instability. I HATE IIR.
Okay, sans choice, it will have to be done right.
