    MAPS - Update!

    Here is updated map information for the upcoming Cochrane Winter Rally!

    There are only minor revisions, with one exception. Please note the new location for the Banquet. The GPS coordinates for the Banquet are approximate, based on construction in the area at the time the underlying map tiles were published. The marked location in the linked map file should get you pretty close.

    The Stump Tavern
    50 Fireside Gate, unit 4151
    Cochrane, AB

    The file linked here is in .kml format:

    Radio Configuration Guide

    Here is a link to the Radio Configuration and Operation Guide for the rally. This document has the operating frequencies for the event as well as recommendations for effective communication practices. Please take careful note of the guidance for minimizing interference, especially as it pertains to cross-band configurations. An extra channel is added this year due to reliability concerns with some of the repeaters. This provides options in case of system problems.

    There is one amateur looking for a ride to and from the event. (out of Elliston Park).   We have a couple of roles we can put him in if we can get him there.

    If anyone is able to help with this -

    Here is map information for the upcoming Cochrane Winter Rally!

    The file linked to here is in .kml format:


    In the past, the .gpx version of this information has been requested, as it loads more readily into GPS units and APRS software. This is easy to do using any online converter. I use the one at the link below. (Note: I do have to manually change the file type to .gpx after I download the file from this site.)


    The placemark labels begin with "CWR" which stands for "Cochrane Winter Rally". Using this prefix enables electronic tools, such as APRS, to collate all of this event's objects when they are sorted and reduce object name collisions with other users. It also makes it easier to differentiate this event's objects from others that may appear on the map.

    Blocker and Control Point locations start with "CWRL" meaning "CWR Location". This allows us to differentiate a location from the operator(s) who may, or may not, be there at any given time. That is, a location exists on its own, regardless of whether or not anyone is there at the time. Again, this can be important for tools such as APRS. So, the location assigned to Blocker 310 is labelled as CWRL310. CWRLA is location Alpha. These examples should help you to understand the labelling scheme.

    Please note the use of the new three digit blocker location numbering format. An explanation of how this works is provided in the updated "Radio Operations at Rallysport Events '101'" guide posted earlier in this forum.

    Another new map feature is the set of CWRCTN?? placemarks. These refer to "CWR Caution" locations, near which drivers should exercise additional care due to road conditions or other hazards. Bear in mind that drivers should always be prepared for such things when at a rally venue, and these placemarks should not be considered an exhaustive list of all hazardous conditions. Nonetheless, these are some specific locations and stretches that warrant special attention. 

    Finally, here are instructions about how to open a .kml file in Google Maps, in case you want to create your own detailed views.


    Stay tuned to this forum as more material will be posted over the next few days.

    An email was just sent (2020-02-26 ~23:25) to everybody who has, so far, registered at the site and indicated a Radio role.

    If you have signed up, and did not see an email - please contact me, and we will straighten it out.

    We will be assigning positions over the next few days, and are still looking to fill some roles.  Please sign up if haven't yet and you'd like to participate, or contact me if you'd prefer to discuss the event first before signing up.

    Assignments will be posted here once they're completed next week.

    Radio Operators Meeting will be at the Calgary Sports Car Club (4215 80th Ave NE Calgary)    Friday 6 March from 19:00 to 20:00,  and event day for most of the radio roles is Sunday 8 March.

    Radio Operations at Rallysport Events '101'

    To ensure that our radio operators are comfortable with common rally terminology, I ask that everyone take a few minutes to review the '101' guide, linked below.

    This document is intended to provide rally radio operators with a foundational understanding of what happens at a rally, who is involved, and where to find more information. Key terms are explained, roles are described, and some important practices are presented.

    Please take the time to download a copy and read it prior to the pre-op briefing. While this guide is oriented at people who have had little exposure to rally events, experienced operators may also benefit from a refresher. In any case, the briefing will assume that everyone is familiar with the contents of this guide. While specific questions about the '101' material will be addressed, we will not be presenting these basics during the pre-op briefing.

    WIlson has a great point and even if you don't have a cross band radio there is something to learn here.  If someone around your location is using cross band there is the opportunity to use that set up if you have a hand held radio.  Knowing how cross band works will aid you in using someones set up if needed.  There are subtle nuances to using cross band like pausing before speaking and not clipping your transmission.  Much to learn at this session and very timely for the rally.

    Come out to the CARA VHF interest group on Feb 18 @ 7:30 PM @ Denny's on 19 ST NE for demonstrations of cross band repeater set up on a variety of radios - Kenwood, Yaesu, Icom, etc. We'll be demonstrating menu settings and talking about operating practices.

    Many radio operators at rallies use cross band repeating functions to allow movement freedom away from their mobile radios in vehicles. So, we are providing this opportunity before the 2020 Cochrane Rally.
