Here is the skinny:
Running MixW with VAC 3.11 with Preview 13 runs fine.
Using the same settings as Preview 13, when I start MixW when running
Preview 14, I get:
Application error MixW2.exe
The exception Floating-point overflow
(0xc091) occurred in the application at location 0x004c869a
OK, it may not be a problem after all. I rebooted my computer (shuts
down VAC) and now all seems to be working OK. Windows. Go figure.
There is a 3.12 version of VAC. Anyone know what was fixed between
versions 3.11 and 3.12?

Yes, Duane same here, but still a difference
between Preview 12 and 14.
In Preview 14 hiding the panadapter display with
the Windoze Task Manager drops the CPU to 5-10%
from 15-20% when it is exposed.
But in Preview 12 hiding the panadapter display with
the Windoze Task Manager drops the CPU to
With 1.4.4 8%
Beta 8 14%
Beta 12 19%
Beta 14 19%

not see the same behavior with 12 here. Here's my more
detailed results for the CPU usage range for PowerSDR.exe as
seen in Task Manager (Panadapter Display Mode):
12 covered 2-5% (~avg. 4).
12 exposed 3-6% (~avg. 5).

About double or triple the utilization of release 12 as measured by
task manager. Disabling panadapter reduces both versions
significantly, but the same ratio increase applies.

Golly, maybe one of the C# programmers out there can grab
the source and run a profiler to see where the cycles are
going? is there such a utility in the Visual Studio 2003/2005?

In version 13 as you reduce the power on the console the AM carrier reduces
and by turning up the audio you can obtain full peak output, allowing reduced
carrier dsb operation. This IS desirable.
In version 14 when you reduce the power on the console the entire AM signal
is reduced- carrier

What soundcard are you using? I had this happen when using a Delta 44
and the issue was that some other windows program changed the variable
signal levels to a value that the SDR didn't like. P14 does an auto set
of the signal levels for the Firebox and Delta 44.

Bob,
When you're ready, perhaps you could post it somewhere where it's available
to more people, say the download section of the hamsdr site? I think, with
all the mods going on some of us have started to lose track of what happens
where in the chain (I know I have).
Thanks,

It will be a replacement for the DttSP thing already started, with the
formatting improved, and more features.

Hi all,
I noticed that there is no output power indication on
CW if the PA is not installed or the VHF+ bands are
used. This happens with the latest previews as well as
preview 12. It is a problem that will not be noticed
by those using the PA.
I'd like to confirm if other have experienced the
Hi
I find the ANF (Automatic Notch Filter) not working anymore. Neither did it work
in Preview 12. Do others expierience this?
The ALC is a great improvement to the radio!
Here I don't remark a CPU increase, it is around 8 to 12% but from time to time
it jumps to more than 50% for a few
ANF works on Prev. 12 just fine here. Make sure the BIN is OFF.

Chris,
I had a problem with it in Pre 13 because once I needed it. I just
tried it in Pre 14 and it knocks a carrier down about 20 dB. Seems
it could do better.

That is an oversight in the release notes, I forgot that I modified the
gain settings to make the thing actually work!
If you have the Block LMS enable for automatic notch filter, you will
notice an immediate improvement over version 13.0. About all that
happened in the earlier releases is
I only have one word to say, OUTSTANDING!

I find in particular, the noise reduction filter is
really nice.
This is great, Bob, it is now even fast enough to cancel CW signals effectivly,
hi, and it works indeed with BIN on. I have forgotten the Block LMS keys: the
radio gets better and better even if we are not aware of it at once! The
discription is also up to date in the manual 1.5.15. By the way,
Bill:
Unfortunately Bill this is not what was happening in versions 13 and
earlier.
Take version 13 and put it into scope mode on the display. You will
see the negative peaks of the modulation going below zero. This is
straightforward overmodulation and will induce a phase inversion and

You are correct, Jim. The thing we are trying to determine, however,
is why the cpu loading increased from preview 13 to 14 and only on
certain folks systems. The behaviour relative to covering the window
has been present in earlier versions.

Bob,
I engaged Block LMS and what an improvement in NR and ANF. Big
improvement in ALC too in pre 14. I kept cranking up the mike gain,
as I didn't see that I had nearly 100 watts output. Finally hooked
up my Autec computing watt meter which reads true peak, and had to
back the mike gain
Jim,
I am one of the first to report the CPU increase issue. I am using a
NVIDIA GeForce 6200 (latest drivers DirectX).
Turning off write combing made little difference. Eliminating hardware
acceleration made CPU utilization go higher.
