I have been doing some evaluations of Linsim and I have
identified a couple of minor issues.?
In my early tests, I selected 1 path and a spread of 1Hz and
and AWGN with SNR=25dB.?
I did one set of tests at a sample rate of 8kbs and another
set at 48kbs. I repeated the tests?
with path 1 selected, a spread of 1Hz, and an offset of +5Hz.?
?
I am using Windows 11+Dell G10 laptop.
?
Observations
?
1. I intercomapared Linsim v2.0.4 and and Moe Wheatley's
Pathsim v1.0. I generated a 1kHz sinewave
with a 60 sec duration at a sample rate of 8kbs. In this case
the time domain wave forms exhibited
very similar envelope fluctuations. When I performed an FFT on
the records the resulting spectra
exhibited a Gaussian shape with the same width. When I applied
an offset of +5.0Hz, the spectrum
shifted up by 5.0Hz with Pathsim. With Linsim, the Gaussian
spectrum shifted down by -5.0 Hz. So there?
is a potential sign error with the offset in the Linsim code.
?
2. I performed an additional set of tests with a 1kHz
sinewave with a 60sec duration and a sample
rate of 48kbs. In this case I did not use Pathsim since it
only works with a sample rate of 8kbs.
I first applied the 1kHz sinewave to Linsim with Path 1
selected, a spread of 1 Hz, and 0 offset.
The resulting output waveform exhibited much faster envelope
fluctuations. This was confirmed?
with the FFT, which showed markedly wider Gaussian
spectrum-the width increased approximately 6x.
?
3. I suspected that this spread issue has something to do
with the different data rates since is 6x
larger than the 8kbs case. I then repeated the test with a
spread of 1/6 = 0.166, that?
corresponds to the ratio of the data rates 8kbs/48kbs. The
resulting spectrum using an FFT showed?
the correct shape and frequency spread.
?
4. I think this spreading issue can be corrected in Linsim
by applying a scale factor to the
?spread that accounts for the ratio: 8kbs/(the selected date
rate kbs)--My best guess :-)
?
5. When I applied a +5.0 Hz offset with the 48kbs sinewave the
resulting spectrum shifted down
-5.0 Hz. So this Offset sign error is the same at the higher
sample rates.?
?
Summary
?
1. Linsim is a robust and much needed update to Pathsim
that enables processing of .wav files?
for a variety of data rates in the range 8kbs to 48 kbs.
?
2. When using Linsim at data rates other than 8kbs, adjust
the spread using a scale factor of
8kbs/(the selected data rate kbs).
?
3. There is a sign error in the offset. So simply switch
the sign of the desired frequency offset.
?
4. I have applied pulse trains generated with Matlab to
Linsim and I will report on my findings?
soon.
?

Bob:? thanks for your post.? This
should provide a solution for playing our ARES (or any other) net
control script.? It's always a canned script and it's embarrassing
to fall asleep due to boredom during the script.? Especially when
you're the Net Control? ;o)

Hi Will
I believe separate. <AUDIO:filename> within a macro is
about playing a WAV file as TX audio, whereas the File|Playback
etc is about a creating/using a wav file at a utility or decode
level.
Creating a wav file is useful if that is then passed through a
path simulator, so it can be degraded to test modem performance
played back through fldigi. A recorded remote SDR wav can also
be used in a similar way using a "real" RF path.
Hope this clarifies.

Might also be worth utilising fllog if a separate adif file needs
to be open//viewed, concurrently with fldigi. Also possible to
export>CSV, modify/sort to remove dupes etc in a spreadsheet,
then import from CSV. Lots of options.

affects of tone shaping on a THOR signal on SSB
The ALPHA FLDIGI (4.2.06.19)?? as of Jan 05
2025
The? THOR? alpha (test) modes now have the?? OPTION ? to
include "signal shaping" from 0-8 milliseconds.
This is the rise/fall time of each tone
change.
It should operate in a similar way that the CW
carrier shaping limits the CW bandwidth and reduces "key
clicks" (older rigs).
Can we "see" or hear the changes when?? THOR?
signal shaping is turned ON or OFF?
Here is THOR? TX tone rise/fall times? signal
shaping set to a? 0 ms rise time? (no signal shaping at all)
in the Fldigi MENU
?? 
Here are the? OSCILLOSCOPE? trace (on Fldigi
WF)? and the ? RF Spectra ? captured when I was sending a?
THOR25 signal without signal shaping.
I can't hear the difference (in headphones) but
the RF Spectra? trace does show a cleaner skirt on the RF
signal.
The OSCILLOSCOPE trace has obvious differences
in the tone change amplitudes.
No signal shaping Oscilloscope Trace of THOR25
?? (signal amplitude vs. time)
THOR 25 RF Spectra reveals an??? 800 Hz BW???
at? -30 dB below the peaks.
Now with an? 8 millisecond signal
shaping turned? ON? (TX tone rise time (milliseconds)
Note:? using THOR 25? (25 tones/second)? EACH?
tone ? DURATION? is? 1/25? or? 40
milliseconds.
Oscilloscope Trace:? each tone is about? 40
milliseconds? with an? 8 ms? rise/fall time
The ? RF bandwidth ? of THOR 25? is
reduced by about? 100 Hz? (@ -30dB down)? from 800 Hz to 700
Hz? due to the tone "shaping"

THOR32 signal as seen on HF SSB
THOR 32? on HF? SSB
I was on the NY NBEMS net today (Jan 04 at 8 AM
EST) on? 3583.0 kHz (vfo) and caught the oscilloscope view
(signal vs. time) on FLDIGI
when an op was sending traffic? with? THOR 32?
mode.
Note the signal is not a constant amplitude, at
least not as received by me near Philly.
THOR32? (32 baud or 32 tones/second) results in
a signal duration of? 1/32? or? 0.03125 seconds? (31
milliseconds).
A "tone shaping"? (0 to 8 millisec)? now
available as an option in the "alpha" (test) Fldigi?
4.2.06.16? will alter the rise/fall times of each tone.
????
Here is the AUDIO spectrum of THOR32? as copied
at k3eui on? 3583.0 kHz
Note the BW is about 600 Hz. ? Scale: 200 Hz
per vertical bar
THOR32? usually works well for traffic on 80m
and 40m SSB? - much easier to tune in properly than MFSK32
18 tones, sent one at a time

Re: Run 2 flrigs at the same time.
Hi Tim
The short answer is that a different config file is specified on
the fldigi command line or launcher. eg (from the --help screen)
? --home-dir DIRECTORY
??? Set the home directory to full pathname of DIRECTORY
??? fldigi will put the file stores
????? .fldigi.files, and .nbems.files
??? in this directory
? --config-dir DIRECTORY
??? Look for configuration files in DIRECTORY
Easy way is to create one, copy to another, then alter the copy
for the 2nd rig
Running concurrently will also need port reassignment for sub
pgms like flamp/flmsg. They in turn may also need multiple config
directories.
Also possible to setup symlinks and references to common usage
locations. eg the images directory, cty.dat location and macros
files. (but not the log/adif one)

Re: Run 2 flrigs at the same time.
Have you tried using the command line options to point to a second config file?
Like "--config-dir "C:\Users....."
Clone the original one to a new directory and then use that to start the second instance and then when you change the config it would be saved to its own files.
