In Search of the Great Channel Debate

YRARC has had a standardized VHF/UHF channel list for about 2 years now. It was mostly driven and developed through the efforts of Don, VE3IXJ and has made public service and EmComm operations simpler by allowing us to select repeater and simplex channels without having to memorize frequencies, CTCSS tones and the like, or figure out how to program someone else's radio when the main task is to actually communicate.

Many of us thought it would be a good idea to have some common frequencies so that clubs could also communicate with each other, especially in an emergency, but it has been difficult for clubs to even begin discussing the issue, much less come up with a plan that everyone is willing to implement.

Why is this so difficult? Let us not underestimate the challenges. I see a number of realities and possibilities.
  1. Clubs in the area don't talk to each other all that much. Maybe that's because we don't have a common channel list! Seriously though, while clubs do compete for members and hamfest vendors and attendees to a certain extent, and there is no wider organization other than RAC that represents radio clubs, other than through ARES there are no formal channels for clubs to coordinate activities or share ideas.
  2. ARES/EmComm groups in the region do talk to each other as RAC has district managers and emergency coordinators but reports so far indicate there is little agreement on the topic.
  3. "NIH" (not invented here) is also a possibility. I know we at YRARC like our list (although I wish our D-STAR repeater channels were a little closer to our analogue repeater channels - there's a lot of knob twisting to go from one to the other). It's natural that we all think our own ideas are the best - at least initially. Also our club radios are suited to this list - no cross-band capability but lots of channels available.


But the questions we should really be asking ourselves are:
  1. Why do we want a common channel list? How do we think that will benefit us?
  2. If we had common channels, how would we coordinate their use? In a major disaster, for instance, how would we organize ourselves with nothing but radio, possibly just simplex radio, to do it with? Once organized, how would participants develop situational awareness and be able to brief each other and potentially other agencies, especially NGOs which don't necessarily have access to the communications facilities that we do.
  3. What are the issues that each club has in developing a channel list, and how do we get this issues on the table for discussion?
  4. What are the compatibility problems we face? Clearly not every region has D-STAR repeaters like YRARC does, but likewise YRARC has no System Fusion or DMR repeaters. Many radios available to EmComm members, like the ones we have in club inventory, lack cross-band capabilities. Other regions may be VHF-only. 
  5. What are the coverage issues? Our EmComm group wants to know the coverage of our repeaters, but coverage means different things to different people. Are we looking for full quieting 100% of the time? Is communication with vehicles sufficient or do we need to understand coverage to hand held radios with a rubber duck? At what power level? Our club handhelds have 4 levels from 100mw to 5 watts, and at the highest power level battery life isn't good and the radio gets hot when you talk.
  6. How do we facilitate the discussion that can fully account for each clubs' needs, understand the issues, and drive toward a solution that everyone can live with?
We might even need to ask ourselves more fundamental questions than these before we can get this resolved, about how we are called out in emergencies and by whom, or whether we need to self organize. Do we see ourselves as a "guard network" for official communications or do we need to assist other agencies like St. John Ambulance, the Canadian Red Cross, the Salvation Army, and others, and when do we show up at their door to help?

As you can see I have lots of questions. I can't wait for the debate! I'm hopeful that the August 23rd GTA ARES/EmComm meeting will move the ball forward in a meaningful way.

YRARC Supports the Newmarket Jazz Festival

From Don VE3IXJ

I would like to take a moment and thank all the radio club members who volunteered to help make the Newmarket Jazz Fest another success this year.

I know those who were present Sunday evening were challenged by the weather events and it was handled very professionally and no one was injured.





The list of volunteers below are the ones that made this event extra safe and special.  They are in no particular order.
  • Alf VA3BLE
  • Don VE3IXJ
  • Rob VE3RQB
  • Barry VA3LLT
  • David VA3DCY
  • Bonnie Stone
  • Robert VA3BXG
  • Mary Fischer
  • Carlos VE3CAZ
  • Geoff VA3GS
  • Ron – KG4CVL
  • Eric VE3EB
From left to right David VA3DCY, Barry VA3LLT, and Rob VE3RQB.



It is also noted that YRP were very happy with the use of the radios on channel 10 as it made communications much simpler for them.

St. John Ambulance did not have any of their radios, and once again, the GMRS radios were particularly useful and SJA could communicate directly with us and YRP.  I was only aware of 3 minor medical emergencies that SJA were able to respond to very quickly having good communications.  It worked very well having their setup next to our trailer as well.

We were also able to successfully use channel 90 prior to the storm where I could observe the King City radar from home and communicate details to the trailer.  Channel 90 is presently on at the REOC radio room on Yonge Street.

Thanks Again,
Don Matthews – VE3IXJ

Repeater Report - Steve VE3UT

In the past, I headed up our club's repeater committee and now, once again, the Board of Directors has given me this task. Our club has a very good collection of machines but we have a number of challenges ahead. The departure of Bruce VE3BV, who has moved North to the Parry Sound area, has left a void to fill. The club has relied on Bruce's technical expertise and “connections” for the past 30+ years and we need to assemble a team of people with various skills to fill that void and keep us on the air. The challenge of keeping our sites or gaining access to new sites will also be an issue in the coming years.

The VE3YRC (147.225+ PL 103.5) site is not likely to remain available and coming up with ideas to keep it on the air from another location is a priority. YRC is the club's flagship repeater. The relocation of VE3YRA (145.350- PL 103.5) to its current temporary home has kept it on the air but ultimately it would be good to see us back at the original site with its superb coverage.

An idea that is just starting to be discussed is the possibility of have YRA and YRC permanently linked with one machine in the West end of York Region (the original YRA site) and another in the East end (actually North East). This would provide seamless VHF coverage of York Region and beyond with some overlapping coverage in places. Gaining a site in Georgina for YRC would solve the problem of spotty coverage there and other eastern locations.

With a link permanently on, users in the southern, western, and central areas of York Region would be able to select YRA or YRC depending on the coverage at their respective locations. For example, Bob WY and Brynn VOD could operate on YRA and talk to me UT and Barry LLT in the East on YRC. I mention these names because we all live or travel through noisy locations.

The club owns four repeater controllers, two 7330 units (on YRC and YRA) and a ACC RC85 (on YRC UHF) and a ACC RC96 (in the club trailer). The 7330 controllers are newer than the obsolete ACC units. The first 7330 was programmed and installed on YRC by Bruce BV and one was installed a couple of years ago on YRA when its ACC unit malfunctioned. Bruce was the only expert in the club on programming these controllers with me having a limited knowledge. But with Bruce's move, I have stepped up to the plate and am getting fairly proficient at programming them.

At this time, YRC is doing a fair bit of chatting at us. Some of the messages are regular daily messages and some are temporary for special club activities. They all serve the same purpose, to keep membership informed of upcoming activities. Please support our club and volunteer to help out at some of the events. Message schedule on YRC:
  • :00 Time and chimes
  • :10 Hamfest message, last week of October only
  • :15 Month long Hamfest message commencing October 1
  • :17 Tuesday club meeting message, last week of the month only
  • :20 Wildcard message – currently Run for the Cure event
  • :25 Wildcard message – currently Emcomm event at Markham Fair
  • :30 Time and ``this is VE3YRC repeater home of the YRARC``
  • :40 Same as:10
  • :45 same as :15
  • :47 same as :17
  • :50 same as :20
  • :55 same as 25
Last but not least...VE3YRK B and VE3YRK C, our D Star repeaters, great coverage and connect to international gateways. Check them out! borrow a club radio and get on the air!! These radios have FM and can also be used with YRA and YRC. [Note from Chris VE3NRT: Some members have already requested club radios which will be fulfilled at the next meeting]

Links of the Month - March 2014

The following links were submitted by club members in March.
Here is a waterfall snapshot of the suspected OTH signal on the 30 metre band on March 23rd. Bandwidth is about 20KHz, right over the digital segment of the band.
