Important changes to local APRS digipeater infrastructure


Recently we made some changes to the APRS digipeater infrastructure on the all of the digipeaters managed by the Saskatoon Amateur Radio Club.  Due to some recent changes in our digipeater equipment we have had to drop support for all old style paths including RELAY, WIDE and TRACE on all of our digipeaters.  We currently only support WIDEn-n up to WIDE3-3.  WIDEn-n paths higher than WIDE3-3 will still be digipeated but will be truncated.  All other legacy paths including RELAY will no longer be digipeated.  For more information on the "New N Paradigm" or WIDEn-n please visit http://www.aprs.org/fix14439.html .

 

VE5RHF

In the fall of 2001 the Saskatoon Amateur Radio Club commissioned a permanent APRS digipeater for the Saskatoon area.  Operating under the VE5RHF call sign and perched high atop Luther Tower, it provides coverage in approximately a 50-75 km radius around Saskatoon.

Local APRS traffic is passed to the internet via the VE5BNC-3 gateway.

The digipeater consists of an Azden PCS-6000 radio, MFJ-1274 TNC and a 10 amp power supply.  The antenna is a simple J-pole, that's side mounted to one of the existing antenna structures.

VE5YR-4

On October 10, 2003 the Davidson digipeater, VE5DPR-4, was installed installed on the Saskatchewan Wheat Pool elevator just south of the town of Davidson.  Located near the midpoint between Saskatoon and Regina, it provides additional coverage for travelers along this route.  In 2004, the call sign of this digipeater was changed to VE5YR-4.  At this time the temporary antenna and feedline were replaced with Heliax and a Ringo Ranger.

The Digipeater is housed in an old freezer that was hoisted to the top of the elevator.  It provides some limited protection from the extremely dusty environment and insulates it from the -40 degree temperatures in winter.  The freezer is also home to VE5YR-7 packet digipeater.  The antenna is located at near the top of the superstructure.

The digipeater was assembled from equipment donated by several club members and noted below:

MFJ-1270B TNC - VE5LPP
Motorola MCX90 VHF radio  - VE5BNC
Heliax feedline - Saskatoon Amateur Radio Club
Ringo Ranger II - Saskatoon Amateur Radio Club

VE5HAN-4

On October 22, 2005 the Hanley digipeater, VE5HAN-4, was installed about 5 km east of the town of Hanley.  It coexists with the VE5HAN-3 packet digipeater.  This digipeater closes the gap in the coverage between VE5RHF and VE5YR-4.  It's also provides some additional coverage on Highway 16 east of Saskatoon and unexpectedly also on Highway 7 south west of Saskatoon.

The digipeater was assembled from equipment donated by club members and noted below:

MFJ-1274 TNC - VE5BNC
