Bill,
You get a kind of stereo impression with BIN enabled when receiving AM
with
USB, LSB or DSB mode. However you have to tune carefully to zero beat to
suppress the carrier in order to avoid a beat note.

Seems that the MON button works on SSB but not on AM. It would be very
useful to have it active in AM.

It will be in the same folder as powersdr.exe. This will be either ..
\bin\debug or .\.bin\release depending on how you compiled. I always
use debug and never to a complete release.

Richard,
I should have known better than to make even a simple code change, and
not test it. The code was correctly limiting the upload length to 40MB,
but the server was limiting it to approx. 16MB. That has been corrected
- although I still haven't attempted to upload a 40 MB file because it
takes a while with my lousy bandwidth. I will try it though.
So, please try uploading your file again when you have a chance, and let
me know if it worked.
Thanks!

Folks,
The maximum filesize limit for uploads, has been increased from 10 MB to
40 MB.
When uploading .wav and other media files, please consider compressing
them first with a 'zip' utility. This will typically reduce a .wav
file's size by about 30%. More importantly though, it will present the
file as a 'compressed' file and NOT as a media file. Transfer problems
may occur when attempting to transfer a media file with a .wav or .mp3
extension because media players will frequently attempt to play the
files - rather than download them. This will not occur if the file
extension is ".zip".
Also, please use the "Note" field associated with each uploaded file, to
provide any useful information about the content of your file.
As always, we welcome and encourage suggestions about ways to enable
HamSDR to better serve the SDR community. If you have ideas for new
functionality, or suggestions for improvements to existing
functionality, please let us know! (Click on the 'Contact' link at the
lower right corner of every page).
And - please consider uploading photos of your projects, shack,
antennas, four-legged op's, two-legged op's, etc., to your HamSDR
profile pages.
Thanks!

To follow up, the mdb file is created dynamically the first time the
program
is run. So the file does not exist before that point.

Bill,
The fact that we have never enabled a transmit monitor for AM stems from
our
heritage. Using a soundcard with a single stereo in/out connection, you
only have one output to work with. Since we do AM at an IF, this made
monitoring impossible.
Along comes cards with multiple stereo in/out connections like the Delta
44
and FireBox. This could enable us to output the demodulated AM on the
monitor while continuing to output great AM audio to the radio at an IF.
This has been discussed, but not yet implemented as this will require
significant changes on both the interface and DSP sides. Considering that
we have already discussed this, you can imagine that it is fairly high in
the queue of features to be implemented.

Chas,
These settings will vary with voice/microphone/soundcard setup. Also, you
may use different settings when operating in different modes or
environments
(hence the Transmit Profiles). Please see the control descriptions for
the
Compander/Compressor/TXEQ in Chapter 7 of the Operating Manual. Further
reading may be found on our download page in the document about setting up
your audio written by W5GI.

GM,
Now that I have everything on my Power Console, pre 12 working with
the Firebox except some CAT issues (previously reported), I want to
set up the finer points. What are the proper settings for Compand,
Compression and the transmit equalizer? How do you know, and how do
you test it? Tnx.

Subject: [Flexradio] Proof-of-concept successful!
To: <[email protected]>, "Xylo-SDR Discussion"
<[EMAIL PROTECTED]>
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset="iso-8859-1"
This weekend Bill, KD5TFD, completed his integration of our Wolfson A/D +
Xylo FPGA + USB interface into PowerSDR.
This proof-of-concepth has been completely successful and we are eagerly
pushing forward to the next phase of the project.
The screen shot below is of our 48k 16 bit full duplex sound card running
in PowerSDR using an SDR1000 on 20m
http://www.hamsdr.com/dnld.aspx?id=126
The noise floor of the Wolfson A/D in this configuration is -140dBm in a
500z bandwidth. The next steps are to increase the sampling rate to
192kHz and 24 bits.
Bill is also going to implement his system to overcome the frequency error
and drift of the 200MHz Valpey Fisher oscillator. He is using a GPS 1Hz or
10kHz clock to measure the frequency of the DDS output and pass this back
over the same USB signal that carries the digital audio. A software
routine in PowerSDR will then compare the actual DDS frequency to the
desired frequency and make the necessary correction in software. If this
works OK then he will look at counting the 200MHz oscillator directly,
although picking this off the SDR1000 hardware is bit more involved than
the DDS output hence the reason for starting with the DDS output.
We are looking at deriving an LVDS signal from the 200MHz oscillator and
if anyone has any suggestions as to suitable connectors to use with a
single LVDS signal then we would appreciate the information.
There is still plenty of room for more C++ and FPGA developers if you are
interested in assisting with the project - those willing to lay out PCB's
will be especially welcome!

I assume you're actually talking about a differential pair LVDS signal.
IEEE 1394/Firewire uses multiple pairs of LVDS signals at those kinds of
rates.
SATA (Serial ATA) uses a 7 pin connector to carry a pair of LVDS signals:
Gnd, pair A, gnd, pair B, gnd.
We use 9 pin Micro-D connectors for 100 Mbps+ SpaceWire signals (4 LVDS
pairs). But, they're fragile and expensive.
A good quality 100 Mbps ethernet jack and cat5 cable can also do it.
The real key is in board layout behind the connector.

you're a quarter of a Megahertz off? Out of what frequency?
Actually, no matter what, that's a huge error. I'd say you have a bad
oscillator.

I'd made some measurements on my radio a few weeks ago and came up with a
Freq vs. Temp variation of roughly 0.2 ppm/degree F. At 5 MHz (where I'd
made the measurement), this works out to roughly a 40 Hz shift for a 40
degree change in temperature. (Only the temperature of the radio itself
was
changed; the PC was kept at a constant ambient temperature.)
I didn't try it from a cold start, though.
