We have posted an on-line video showing the advantages and operation of
the new RF Tracking Notch Filter (TNF) available in PowerSDR 2.2.3 along
with a white paper describing how TNF was implemented for the more
technical user.
You can access both here:

Enjoy.
Great tutorial, Tim! I have been using TNF for some time (and am blown away by
it) but the video white paper taught me a few new tricks. Amazing feature
which as far as I know no other radio can come close to touching. Nice work,
and nice presentation. Keep up the good work, you guys are
Not sure I fully understand what you're encountering, and you don't say if
you're running F5K with R2?
If the latter, it is best (IMHO) to set the R1 volume pan to 100% left
channel and R2 volume 100% pan to right channel.
Then, in the Multi-RX window, set both audio gain sliders (the
Hi Scott,
A few weeks ago I noticed something unusual when stopping PowerSDR and
shutting it down that might be related. Because I recently installed a
different computer to handle Flex duties in my station I have been
watching DPC latency fairly closely on the new system to see how it
The short answer is that, it shouldn't matter if there is a long wait
(several thousand microseconds) for a DPC to complete while PowerSDR is
shutting down. The OS is what controls that. During the DPC, things
are waiting gracefully. After the audio stream is stopped, the
in-memory DB is
The FlexRadio Global form (Firewire control panel) is the incorrect
place to change sampling rates. PowerSDR syncs the sampling rate with
the Firewire driver. The reverse of that is not true, as it is a
master/slave relationship and PowerSDR is the master controller of the
process.
There
Set the DRIVE control to 0. No RF will be transmitted.

When I do this, after less than a minute of keying, the temp
(CTRL+SHIFT+I) shoots up over 100 C. Fans set to go on at 40C. Will this
harm the Flex3000?
Thanks.

Ive observed a view things with the FM Mic level control and wanted to
verify if the behaviors are as designed or there is an anomaly (or I screwed
something up !).
- The FM Mic gain (the Mic gain slider present on the powerSDR Main form
when FM mode is selected) operates independently of the
Tim:
True, but don't set power to 0 and expect to monitor digital transmissions.
I did this and got nothing but a continuous carrier on the other receiver.
When I increased power only slighly, the modualtion tones began.
I mentioned this to Greg Jurrens, K5GJ, at a hamfest a few weeks ago
Dave,
You are very observant. I'll have to confer with the code Gurus to
determine if this is a by design or an software defect. I'll get back
to you on it.

Tim,And while you're at it, please ask the code gurus if it was their intention
to blow us out of our chair with FM audio levels? Where I have the non-FM
audio set at maybe 45-50, if I happen to click into a band that had FM set, I
must jump to drop the audio control for FM to perhaps 2. I
What version of PowerSDR are you using?

Hi all,
Just upgraded from PSDR v.2.0.22 to 2.2.3 and now I can't set my VAC sample
rate above 48K in PSDR. The pan display seemed smoother before, probably due
to this setting?
Am using a 5000A with Win7 (32 bit), VAC 4.09 and Com0Com. My notes show that
I had set the sample rate at 96K
The max VAC sampling rate you can set in PowerSDR is 48K. Has been
since VAC was first introduced as a feature in PowerSDR.
