Some help needed

Michael Mitchell <mitchellwm4mm@...>
 

I run fldigi with cat control. It works well but one small problem. When I start a macro to transmit a message it takes 10 to 15 seconds to key the xmitter. (FLRIG USED) Also when I change frequency on the radio it takes several seconds to show up on the digi main screen.
Thanks
Mike


Re: New feature for FLDIGI or N1MM

A few years ago I used Microsoft speech to text to convert my voice to text in FLdigi. It worked great especially when someone asks a question that needs a qick answer. In operation you had to click in the text window of FLdigi and just speak into the microphone. I did have to manually click on the on screen xmit but to start and end the transmit.
I quit using because I got a new PC and just didnt bother to redo the program. If you are interested let me know and I will set it up again and send you the settings I used.

If you are feeling especially brave, lucky and reckless you can edit the macro definition file using a text editor.  The mdf files are in fldigi.files\macros\

You should not be executing fldigi when editing the macro file with a text editor.

For instance if you want to swap two macros positions then Select All and Cut from the first one then go to the second one and paste at the end of that one. Now select only the older part of the second macro and right click and select cut. Now go back to the first one and right click and paste in the now empty first location. Of course edit the button descriptions.

John,

You can create macros for other stations without changing your default configuration.

<WX:xxxx> = get weather data for station.

You would have to know the 4 digit code for the other stations.

Re: Cw help

 

In most new rigs, the dial frequency is the actual frequency on transmit if you are using either CW-L or CW-U – the rig takes care of the audio tone and mode when calculating dial frequency. If you are using USB or USB-D with MCW (keyed audio) then the actual frequency is dial frequency plus your audio frequency.

Re: Cw help

CW is an amplitude modulated signal with sidebands that extend out below and above the carrier.  The shape and power density of the sidebands is a function of keying speed and keying waveshape.  This is what the spectrum of a 20 WPM CW signal with a 4 msec rise and fall time looks like:



To insure that no lower sideband energy greater than 30 dB below the carrier was outside of the band edge you would have to put the carrier about 100 Hertz about the band edge, 14000.100.

Re: FLDIGI 4.1.18 watefall fft different from previous versions

Dave
 

There are some small differences in waterfall processing between 4.1.14 and the current alpha 4.1.18.40.  The changes were made specifically to improve CPU performance and to make the waterfall appearance independent of modem sampling rate.  You can expect that the waterfall appearance at FAST drop down will not be as distinct as NORMAL, and NORMAL not distinct as SLOW.  This is a result of latency reduction.  The waterfall is a time/amplitude representation of the audio spectrum computed using a Fast Fourier Transform.  The sample set size for the SLOW, NORMAL and FAST drop rates vary by 4x, 2x and 1x respectively and the computation cycle changes by 1x, 2x, 4x.  The latency is selected to give a quality view in the NORMAL drop rate.



SLOW drop rate
WF expanded to 4x


NORMAL drop rate
WF expanded to 4x


FAST drop rate
WF expanded to 4x

Image is an Rx capture of a generated transmit wav file, CQ CQ CQ DE W1HKJ K, psk31 mode.

The purpose of the waterfall is to provide s visual assist to signal mode identification and acquisition.  It is not an analytical tool.  fldigi does have a signal analysis tool available, menu item "View/Spectrum scope"



Shown above for the same signal.

I can assist you with where in the code to make changes If you are interested in testing your display and cpu usage for various amount of FFT latency.  You will have to compile fldigi for your testing.  The fldigi wiki provide information on how to build from code on various operating systems and computer platforms.

I have also fldigi 4.1.18 and tried a little bit.

What is working: <WX> without additional parameter. I tried KMDQ  (default) and EDDK (near to my location). Has to be set in the WX-Configuration part.

Not working is, if I try  <WX:KMDQ> or <WX:EDDK>. Equal if the same or another value is set in the WX-configuration part.

Seems giving the parameter do not working ?

Older versiions and grasping at straws ... neither will solve the problem.

Send me a copy of this file "fldigi_def.xml".  Find it easily by using the fldigi menu item "File/Folders/Fldigi config ...".  Send it to my bellsouth.net address.

 A few comments on sending/receiving CW  with FLDIGI

1)  The waterfall display settings  (-25, 70) only affect what you see on the FLDIGI waterfall.
    They do NOT alter what the sound card hears for CW decoding.
   The waterfall is only a visual aid.

2) Try turning OFF  the  AFC  option  (lower right) and see if that helps put proper print on screen.
   I notice AFC on some other digital modes often keeps "searching" for the center, wanders off the sender's frequency, and can't find its way back.  That reminds me of when I search for my car in a parking lot and I can't remember where I parked!  What is my search algorithm?

3) Try copying W1AW  CW bulletins at night.
    When I tune in to  3581.5 at night (over S9) FLDIGI copies nearly 100% at all speeds.

Experiment with changing the radio's  IF filter bandwidth. Don't make it too narrow.
Let FLDGI sound card do the "filtering".

I also find that FLDIGI copies just as well when my radio is in USB mode, not CW.
Of course, FLDIGI is in CW mode.
The pitch may change a bit compared to the CW offset pitch of 400-700 Hz.
So just move your VFO up/down a bit to "center the audio" where you want it.
When I operate CW but with radio in USB mode, I try to keep the pitch set to about 1000 Hz on the FLDIGI wterfall
Surprisingly, if I keep the ALC to zero when I transmit, I can send perfect CW by keying the AUDIO in the sound card with my keyboard, and with my rig in USB mode.  The receiving station of course does not know this, nor cares HOW I generate the dits/dahs.

Writing software to decode CW must be difficult, since the noise comes in pulses, especially on 80m.
Does setting the "noise reduction" digital filter to ON help any with CW?

I've had no problems with CW on any of my Icom rigs with rig in CW or USB.
I also set the sound level input to around  -20dB

I don't know Dave, my setting were very close to yours (tried also exactly the same ones) but a difference with waterfall of 4.1.14 is clearly visibile.
I attach a screenshot with fft averaging disabled in both versions, the issue is noticeable in the same way.+
I'm using Win7 64 bit with discrete Nvidia GeForce210.

Since your screenshot shows "normal" waterfall speed, I have tested setting speed to "normal" in both versions instead of "fast", and the waterfall are much more similar, very very close. But using fast speed situation looks different.

I attach also a couple of screenshots taken with normal and fast speed setting, where the different appearance of the waterfall could be more easy to visualize.

I attach a screenshot with a comparison 4.1.18.40 (left) and 4.1.14 (right) even it's not so clear the difference as it's seeing the waterfall moving.

One thing I see is that the squelch function seems not to be turned on.  It filters the gibberish that your fldigi is otherwise required to 'interpret'.

Set sql  to ON  and set the level such that only the Sent Code that you want to hear,  is interpreted by fldigi as Heard Code.  Anything below the level you set will be ignored.  It's a bit of a dance!

That may blow away much of the "chaff".

I am having this problem but now it is June of 2021 and I am on the latest version of Windows.  The Flex works OK otherwise.  I have not tried FLDigi for many months.  I have checked Privacy and all are enabled there OK.  What now?
