Success Story using Raspberry Pi, APRStt, and Dire Wolf

You've probably seen our postings on Dire Wolf with the Raspberry Pi.  Keith Kaiser from Kansas City Northland ARES had the following report to post on linuxham group on their SET exercise.  Very encouraging!

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 software 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 APRStt 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.

Many changes including a new modem type, IFKP. Please use this help
version with the 3.22.14 beta release.

* IFKP help: http://www.w1hkj.com/alpha/fldigi/beta-help/ifkp_page.html

I suggest using these calling frequencies when testing IFKP

* 30 meters, 10.143, +1500 Hz on waterfall
* 20 meters, 14.068, + 1500 Hz on waterfall

Change Log from 3.22.13:

Version 3.22.14 beta

ifkp modem
* Incremental Frequency Keyed + modem
- wide band, moderate speed differential MFSK signal
with offset +1.
- sample rate 16000
- symbol length 4096
- 33 tones spaced 3xSR/symlen apart approximately 398 Hz
bandwidth.
- multiple image transfer formats similar to FSQ
. Avatar (57x74 WxH pixel) image transfers
- tunable modem subcarrier (center freq)
. may be configured fixed at 1500 Hz or
. set to Psk sweet spot
- raw data received written to audit log - if enabled
- heard list entries written to heard log - if enbled

Macros
* Added @WAIT macro
* Added disable macro timer when changing modems

WEFAX hang on INFO
* WEFAX rx becomes unresponsive when writing to INFO log

MXE update
* code changes for update to mxe suite (Windows build)

QSO rec
* Changed qsorec data store to an arrary of string pointers
vice an array of strings.
- new mxe implementation string handler changes from standard
gnu string template

MS Read logbook
* change to "rb" for correct reading of logbook file
- do not allow M$ to make changes to CR/LF counts

Nu opBW combos

LSB modes
* Add recognition of flrig LSB modes
- adjust waterfall for LSB
- correct logging frequency for LSB

Doxygen help
* Update to doxgen to 1.8.10
- Corrected various doxygen parse errors

FSQ updates
* Fix copy all on heard list
* change default color scheme as requested by ZL1BPU
- added user configuration items for RX text colors
* remove "MONITOR" text from RX panel as requested by ZL1BPU
* added fsq tx text queue to handle case when user
tries to force a second transmit sequence when modem
is already in TX state.
* last_command updated to include both queued and transmitted
text string.
- allows recall of queued command even if transmit timed out
* last_command changed to a stack of commands
- allows recall of up to last 10 commands
- each press of F2 recalls one deeper in stack
- rotates back to beginning after recall of most ancient
* add call to logbook using right click on heard entry
* Fix erroneous date in audit log when fsq is default
modem during program start
- change format of date entry to make it easier to
find when reviewing the log.
* Added video text at beginning of transmit
- also adds ability to transmit pretone
for amplifier carrier detect
for FM repeater operation
* Add code to force center frequency to 1500
when switching from another modem
* Fix to avoid time out errors
