Eric,
random DSB occurred with Delta44 and FIREBOX
as well. The effect is not related to consumer cards.

The old download URL

Can not download the Source code for Preview 13.

Yes. I have seen this problem. Mine has been corrected by
hitting the push-to-talk several times.

Well, I have sort of a variation of the power glitch described. I though it
was just me or my hardware, but perhaps it is related to a version of
software. For me it has not always done it, but at for version 12 and
perhaps one before. This I would need to test as it has crept in over the

One thing that is very different in the SDR-1000/PowerSDR from Leiff's
excellent article is that our final brick wall filter is AFTER all speech
processing, including ALC. This means that it filters out most of the
splatter before it ever gets amplified. I verified this on a spectrum
analyzer
Lee,
Nice and simple. In fact, there is really no reason for an OFF state.
I find turning on the crosshair just one more thing to do when
powering up the radio.

We do have something like this on our SetupForm - Test Tab. But don't let
this stop you from trying your own version. :)

The reworked ALC is awesome and totally transparant. It's the first time in
the history of rice boxes that an alc has actually worked without massive
distortion! Also, the peak power distortion on the 1 watt predriver is cleaned
up.
The peak power meter shows around 125 for ssb and 200 for am
We have this very thing on our list: To come up with a list of tests
that we could run internally and that customers could use for regression
testing of new Beta releases.

Shouldn't peak power for AM be exactly the same as SSB?In other words, if I cannot transmit more than 125 watts, peak, with SSB (to prevent amplifier distortion), then I'd think that I shouldn't be able to transmit more than 125 watts, peak, with AM (andthe AM carrier power should be 1/4 of
There is a phenomena in linear amps that are used to transmit AM: The AM
carrier causes a flywheel effect which fills in the missing parts of the rf
cycle. This allows operation at higher peak powers without i-m distortion
being generated.
This does NOT happen in ssb modes.
Thus you can run
Gerald and Paul,
I don't have the DUBUS article around. How exactly is the compression
done in SDR-1000? According to my understanding the compression will
increase the INBAND intermodulation distortion, unless the audio
spectrum is sliced to narrow subbands that are individually compressed
Bill,
Glad to hear that the new ALC is to your liking. The peak power meter
is still not right as far as I can tell. AM peak should not be 200W,
unless I am missing something.
The Leveler is used basically to apply a very slow AGC to the microphone
in order to keep the volume from dropping
The link was fixed this morning. Sorry about that.

I read the release notes and, yes, I experience exactly what was described:

You've got sample WAV files for things like SSB and AM signals off the air,
but it would be quite handy if you would post some sample WAV files with
things like single tones or two tones, and tell us what they are (i.e.
where is the center frequency: 11.025 or what).
That way, we can
Gary,
After I got this message, I went back and took my measurements again
using a scope. I am seeing peak power up to ~140W with the AVG power
around 45W depending on voice characteristics. This is what we were
targeting with the new ALC.
Why should you be happy with this? Because it is an
PowerSDR Beta v1.4.5 Preview 14
has been Released.
This release has quite a few bug fixes
including the TXEQ which was broken in the last release. It also introduces W5SXD's CWX form for
more CW sending options. Please
read the release notes for more information.

Hi,
There's an item that I noticed in preview 12 and also in preview
13. When in Setup under the Transmit tab, you have the ability to
define your own profile and save it. But when you restart Power
Console, the saved profile is not there any more.

I would like a description of each receiver sample IF file that is already posted on the site. It is not clear to me where to set the receiver when playing them.---You've got sample WAV files for things like SSB and AM signals off the air, but it would be quite handy if you
The CPU utilization on my system went from 3% with Preview 13 to 30%
with Preview 14. All I did was import the database from 13 to 14 and
started listening to 41 meter shortwave. I did re-run fftw_wisdom.exe
for Preview 14 as I do with all versions and it made no difference in
CPU utilization.
Just installed Pre-14 and have found my CPU
utilization has increased more than double than with
Pre-13. No other changes in software or background
programs.
