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"

Hi All,
I use the Fldigi log when I'm net control. I have several duplicates of calls. I was wondering if there's an easy way to edit the .adi file
that Fldigi creates so I can delete the duplicates and maybe change information or add information.
If I use a text editor it just too hard to edit.

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)
Cheers Bob VK2YQA

Don,
?
In the Shack, I use a M1 Mac, and in my mobile setup Linux. ?
?
The problem is that the radios are different and use fldigi
different HFs for RTTY and and VHF Nbems. ?
?
I wish the mac version Had a config file to load for each
radio that would help. ?

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.

Re: Run 2 flrigs at the same time.
I would use Omnirig for HF. I forgot you are?using Linux. For your dual-band radio, I use memory. I've run across that in using an HT. Back to the drawing board.?

Hi Don,
?
I wish I could use Flrig but unfortunaly my VHF /UHF radio does not have any rig control. ?its a FTM-500.? My HF radio has a custom hamlib script since the Elecraft K4 is not supported by flrig. ?
?
I need to find a way to have seperate profiles for fldigi and that would work.? Too many errors switching between both. ?

I create two folders. In the folder, I'd have Flrig setup for a radio you use.

Jason,

My two radios cannot use FLRIG. The first is the FTM-500 and it does not have rig control.? The Second is the elecraft K4 and it does not use FLRIG for rig control. How can FLDigi have two profiles in Linux or OSX. ?

Thank you David and Happy New Year to you and continued work on
the FLdigi suite of tools. It is a wonderful program. I'm learning
something new all the time about the program's and how they work.
Many Thanks

Thanks Dave,
I thought it was an update for all of the Thor modes when I saw the
General tab.
