proposed changes in 8psk modes

The following changes are proposed for inclusion in the next public 
release of fldigi

     8PSK FEC CPU reduction
      * NOTE: 8PSK 125F and 250F are not compatible with previous versions!
        - all other 8PSK modes retain backwards compatability

      * Lowered CPU requirements to allow for use on Android/Netbook 
        - Lowered 8PSK 125F and 250F to constraint length 13 FEC
        - Adjusted maximum traceback memory for viterbi decoder
        - Set traceback to an optimally-high value in viterbi.cxx 
        - 8PSK - 500F 1000F & 1200F now use only 1 viterbi decoder 
without voting

These changes are specifically to reduce cpu usage on AndFlmsg (Android 
flmsg/fldigi application).  Please respond to both John Phelps, KL4YFD, 
and myself if these changes will adversely effect your current operation 
or seriously impact your code base.

Thank you.

Dave, W1HKJ

Andy's Ham Radio Linux V18 has been released!

Hi everybody,

I have just released version 18 of Andy's Ham Radio Linux.  32-bit and 64-bit versions are available.  This distribution is based on Ubuntu 14.04.3 LTS with customizations for amateur radio users.

There are a lot of upgraded versions, and the addition of KiCad (schematic capture) and dream (digital radio mondiale).  All of the "Fl family" of software (W1HJK and associates) is at the most recent revisions.  The entire list of changes is available at the link shown below.

For more information:

Have a lot of fun, an d 73,

RE: Fldgi No Freq shows

Hi Dave:

I think perhaps I have a problem.  Currently, I'm still using the 
3.21.38 version on my Mint 13
OS.  Everything seems to work OK except that I cannot get a frequency 
readout in the upper
left-hand corner.  It is blank all the time and I have to put in a 
frequency manually although it
seems to have no effect  with the FT-991.  Also, HamLib will not 
communicate with
the FT-991...(error no I/O)...but with RIG CAT, I have no problem.  
Communicates OK but as
above, no frequency is displayed.  Sound card is the card that is 
installed internally in theFT-991.

I have also installed the new version of Fldigi and the sound card 
window is all grayed out
except for I/O line.  Cannot access any sound card.  Any suggestions, Dave??

Until recently, ver. 3.21.38 worked without any problems in Mint l3.  
Since everything else
seems to work properly in Mint 13, found no reason to upgrade to a more 
current version
of Mint.

Thank you much for your input.  Have a nice day!

Best regards and 73,

Hank 7J9AAD

Having USB/Serial issues with El Capitan?

I just recently upgraded my OS to El Capitan and my USB to Serial adapter stopped working with FLRig and with WSJT-X.

I found the solution if anyone else experiences this. Just follow these instructions to get your rig connected again:

Could not check for updates

You should disable the automatic check for updates until the www.w1hkj.com site is restored to full function.  That may not be before the first of November.

For more than a  year the Source Forge site has been used by the developers and users who want to build the bleeding edge versions from source.  The only thing that has changed is the addition of installation files at that site.

Hello Dave,

By start Fldigi I become the error message "Could not check for updates ect...."

I know that you have moved your website to http://sourceforge.net/projects/fldigi/files/

and I hope that the "check for Updates" will be alive for the Sourgeforge site.

Also to for the Online Documentation in the Help Menu of Fldigi and the Check for updates in the same Help Menu

I use the Fldigi on Win10

Thanks again for the UFB program

Re: [NBEMSham] NBEMS / fl_xxx files [3 Attachments]

[Attachment(s) from w1hkj included below]

You have three ways to retrieve the source files::

Either use the "Download Snapshot" link.  It will be a zip file.  Or open a terminal window on linux and execute the "git clone ... " exactly as shown.

Or use the http interface to create the clone

The only git member not visible from this interface is flrig.  But it can be obtained using the git terminal interface

$ git clone git://git.code.sf.net/p/fldigi/flrig flrig.src.git  (name the italic to suit)

The tarball is also available for download from the SF files area

Let me know if you are still having problems.

73, Dave

NBEMS / fl_xxx files

All of the source, setup.exe, and dmg files can be downloaded from 
Source Forge.  Please use that source for all downloads.  If you need 
the source then you can use the git clone process.

Success Story Using Raspberry Pi, APRStt and Dire Wolf

During the recent Simulated Emergency Test (SET) exersize conducted across the county, Kansas City Northland ARES successfully used APRStt to provide position information for each participant to Net Control. This was accomplished by each member checing into the net using a short APRStt Touch Tone pad entry. 

The entire operation was made possible by the use of the Dire Wolf TNC software running on a Raspberry Pi. Dire Wolf, if you are unfamiliar with it is a soft ware modem and APRS encoder/decoder. The Raspberry Pi used two inputs, one for each of the two primary repeaters being used during the SET. Each ARES member was given a two digit number, 13 for example. Each of these numbers was also assigned to the home location of the member by using latitude and longitude.

Dire Wolf has a built in macro system allowing a shortcut method of programming. By setting a TTPOINT macro variable for each ARES member they were able to show their location in just three button pushes. 13# which translates to: WA0TJT at 39.202 , -94.602. 

Additional macro variables were set up for each of the other location of importance in our coverage area. For example each hospital was identified by a TTPOINT, each Shelter, each fire station and a variety of others important locations. A station could then report his/her positon at one of these by simply sending 1398#. The 13 representing the callsign, the 98 the hospital (for example) and the # to complete the APRStt entry.

Using the Dire Wolf macro facility additional capabilities were built using the APRSt t basic concepts. For example it became possible for a station to identify their location by an abbreviated gridsquare. They were also able to add an APRS status code to any of the APRStt messages they wished. 

Using these methods 100% of our stations (about 21) were able to give there location via APRStt and because Dire Wolf can also act as an iGate it allowed them to be posted on aprs.fi.

I want to publicly thank John, WB2OSZ for his most excellent Dire Wolf application, and Bob, WB4APR for APRStt, combined they made for a very successful SET.

HELP ----> flrig & ic7100 & USB-D only operation


     I utilize fldigi extensively in a mixed mode nets.  I use USB for voice comms and then USB-D for the MT63 types modes.  Using fldigi stand alone is fine.  The issue I have is that flrig must also be active in order to transmit.  As soon as flrig is executed the IC-7100 goes into USB-D mode and will not allow manual change.  This limits the usability of the combination of both flrig and fldigi.  

      Previous versions did not have this problem.  I really do not remember which previous version combination worked as there were so many updates and I had been off the air for a few months.  

     Has there been changes in the IC- 7100 portion of flrig that forces the radio into USB-D only mode?  No matter which mode is selected it remains only until the next poll and then automatically reverts back to USB-D.  I do not believe this is the intended way it should operate.

      I have brought this up several times before and it has not been fixed yet.  Hopefully something can be done to fix flrig that will allow the IC-7100 to be placed into any mode not just USB-D.
