Re: Transmit audio level for FM VHF?

Steve Bellner
 

Neil, W0NRP,

I may be answering the wrong question but this has been my experience with HF sound card and VHF sound card settings using a signalink.

On HF you put the radio power on 100 % and adjust the power level with the signalink TX pot. You can adjust it down to 1 or 2 watts. I usually set mine to about 25 to 35 watts depending on the band and conditions.

While observing the waterfall on FLdigi, adjust the RX pot until you have about 50% yellow and 50% blue. This will bring out the weak signals but not too weak.


For VHF you can hit the tune button in the program and listen on your HT. Adjust theTX volume up until it is distorted then adjust it down until it is undistorted.

This also works for VHF using other sound card modes.

73,

Steve / W8TER

On my Windows 10 PC, I am unable to execute fldigi-4.1.15.05_setup.exe

Ok, got AndFlmsg up and running again.  For what it is worth, it took adding the "FTP plug in" to "Total Commander," the phone's file manager. The Google file manager seemed stymied.  Why this worked, don't know.  But was able to reopen the latest AndFlmsg version and get it going.  Hope info useful, 73, KI7MBR Ole

Hi John,

Whatever the Android OS update yesterday did to my phone appears to have blocked; 
  • AndFlmsg settings for location (thus not allowing the app to open),
  • connecting to the desktop to reload AndFlmsg and
  • not allowing either of two file managers to show downloaded files (I delted AndFlmsg and downloaded latest version directly into phone) 
Rats.

Thus the best I can do re the image in the preceding message is to say that the header and footer sure look similar to what appeared on my phone. Apologies.....

Hi John,

Apologies for the late reply.  The above looks familiar.  However, my phone updated its Android operating system and a number of things now do not work, including AndFlmsg.  The phone refuses to take the location permission.  I just deleted the app, will reload and report.  Might be another day or two.

Hi Dave,

 

could you pls take a look to signlal browser in CW?
It still present running QSOs on wrong frequeny.

This Example a QSO on 3530, correctly shown in waterfall as 3529+1000  but in signal browser as 3529+500

Re: Transmit audio level for FM VHF?

Dave
 

Every signal generated by fldigi will have a peak-to-peak audio signal that is equal to or less than the "Tune" signal.  If you follow the advice of Harry or John using the tune signal then all others will be OK.

To adjust audio-levels for FM you can listen to your own voice-signal through a scanner and adjust your digital-Tx-audio to be slightly quieter than voice (to prevent overdriving).
Better to have a too-quiet signal than a too-loud one.

The modes in Fldigi, even the 8PSK modes, are designed to be adjusted by ear without a deviation meter needed.
This is very handy in an emergency situation, hihi.

Since people are using Fldigi more for FM, the manual should have some kind of FM adjustment procedure or info added.

Re: Transmit audio level for FM VHF?

You're right...it's been a while since I've done NBEMS on VHF/UHF FM.  Slightly lower audio level than voice is indeed the best.  And a deviation meter is just not needed.

Re: Transmit audio level for FM VHF?

Randy Allen
 

A member  of one of our local digital training nets did have the proper equipment to measure on air signals.  We spent one net with him monitoring each of our signals (using FLDIGI) and providing feed back.

Maybe check around your area and see if someone (say someone that works in Land Mobile Radio and has access to the equipment) could do that during a net?

One of our local clubs has a person that works in one of the local radios shops with access to a service monitor.  They held a special club meeting where folks could bring their gear in and have it spec'ed out.

Just a couple of ideas
