Recommended Repeater Operating Procedures


  1. Use simplex wherever possible freeing the repeater for necessary uses.
  2. Monitor the repeater (listen) to see if its use before transmitting. Then, if all OK, proceed.
  3. Don’t break into a contact unless you have something to add. Interrupting is no more polite on the air than it is in person. Interruption without identification constitutes malicious (and illegal) interference. The correct trem is “contact” but many use “break”
  4. Use the minimum power to key up the repeater. To make contact, simply indicate that you are on frequency . For example “W1AW monitoring”. Do not kerchunk.
  5. Remember amateur radio transmissions are being monitored by many non-hams with scanners. Watch your language and your manners.
  6. Repeaters are intended to facilitate mobile and portable operation. During rush hours, base stations should relinquish the repeater to commuting mobiles.
  7. Keep transmissions short and thoughtful. Do not monopolize the repeater. Pause between transmissions to allow other amateurs to identify themselves if they wish to use the repeater. Pausing also allows the timer to reset, avoiding a “time-out”
  8. Identify legally. In Canada that means at the beginning and end of a contact and every thirty minutes of operation.
  9. Repeaters are installed and maintained at considerable expense. Regular users of a repeater should financially support the individual or club owner in their efforts to keep the repeater working properly.


Lots of repeaters at LAX


York Region ARC Foxhunt 2017-1 Results


York Region Amateur Radio Club FoxHunt 2017-1 Report


Another great day for Foxhunt training and to the lessons learned from the last one.

We had a great pre hunt social session with breakfast and as soon as the VHARC club members showed up we were ready to roll.


York Region has a lot of hills and valleys which can play havoc with signals as well as the Aurora ridge blocking signals as well.


I was located on Bombay Court in Aurora and offered some interesting terrain. First off I was not visibly from Yonge Street due to the wooden fencing. I was not visible from the side street as I was behind a huge snow pile. So you needed sharps eyes on the s-meter to catch a good bearing.

The Fox box started at 5 watts and then we did a ramp down in power as we progressed during the hunt duration.


The winners are VE3VSR Len and VA3KXP Stephen (visiting from the Victoria – Haliburton ARC) with a time of 10 minutes


VA3GS Geoff and VE3IBW Brian at 120 mins


Participants that were close but no luck within the time frame:



VE3RQX Matthew


Mike and Matthew were within 500 yards after I blurted out my location as we wrapped it up


Lessons Learned:


  1. Attenuation is important as one nears the fox as well as getting a good bearing
  2. Quads may be preferred to yagis due to the antenna lobe pattern to ensure a good bearing up front
  3. A radio with a proper or expanded S-meter is highly useful….3 segment s meters are useless



The behind the scenes Doppler System Proof of Concept (BSEU)  nailed it very quickly which demonstrates the capability of an automated system. Enhancements are being made to a GPS interface integrated with Google Maps and Canada Topo. This will help reduce the amount of noise and interference complaints.


Stay tuned for a February Date

We need your Help – please check your inputs and get a bearing on these Pesky Jammers

Getting close to actual locations but need help on the last mile

One is mobile and jams with his GF or wife in the car and another is a regular on the 401

Another jams from one location during the week and another on weekends

One poor idiot is actually jamming himself in order to raise pity from his community and complaining how he is getting jammed by his haters when in fact he is doing it to himself

Jamming activity is also from the Tim Hortons at two key Toronto locations East of the DVP and south of the 400

Don’t forget the York Region FoxHunt on January 21 9am

Kerchunk ID pattern for the jammer known as the Masterbator69



First of all we need to understand these jammers. That’s not too difficult a task, they are quite simply brain dead morons with very sad lives. Simple, isn’t it? Let’s face it. If the most exciting thing in your life was to sit there and jam a radio repeater, then you would consider yourself a very sad person, wouldn’t you?.This feeling of self low esteem doesn’t seem to bother jammers though, as they aren’t bright enough to understand how sad they look to others. They are little more than unintelligent morons with nothing of interest to say and nothing to contribute to a community, so they make their presence known anonymously. This need for anonymity displays another common trait of a jammer’s character, the cowardice. Jamming is just a cowardly form of bullying.

The kerchunk jammer
This jammer likes to kerchunk the repeater over and over again until the thumb gets tired. He likes to hear the courtesy tone go beep and the repeater go kerchunk. It’s almost like the dripping water torture system.

The digital jammer

This jammer likes to send digital information, like packet or DTMF tones on repeaters.

The good citizen jammer

This jammer masquerades as an upstanding pillar of the community most of the time but makes his disgruntlement with different repeater users or the repeater operator known by disrupting communications. If he can’t operate the system the way he wants, when he wants, then no one gets to use it. He may be part of your group and may even be one of the ones complaining the most about “the jamming”. These are the manipulative type of jammers who try to recruit weaker minded people into their sad cause.

The sound effects jammer

This jammer feeds on indignation and disgust. Sound effects are “his bag” and even a disgusting word or two in a disguised voice. He also likes to play music and often uses a particular recording as his signature tune. His favourite pastime is waiting until someone he dislikes enters into a QSO and then unload his best stuff.

The rabid jammer

These are very sick jammers who have a need to do what they do in order to have some effect to the world around them. Everything else they do is a big zero and the ability to affect a large number of people, even in a negative manner, is just to good an opportunity to pass up.

The brazen jammer

These jammers are usually the ones that have already been caught, or are already known to others, and nobody wants to talk to them anymore. They know nobody wants to talk to them but they continuously call CQ without getting any replies. They see this as a legal way of jamming. What’s even sadder, and funnier, is “who calls CQ through a repeater anyway?”.

Well, not a lot really. You can’t reason with people of low intelligence. On the other hand you can minimise the annoyance factor by the way you react to them. Nothing you can do or say will stop them so simply remove yourself from the loop.

The answer is simply “don’t get stressed, give stress”. The worst insult you can throw at a jammer is to ignore him. Act like he isn’t there. Act like he is of no importance, which of course, he isn’t. It’s hard, but responding in any form means he’s won and you’ve lost. Instead, take satisfaction in the knowledge that by ignoring him you are also annoying him.

Jammers have a need for recognition, so don’t recognise them. Even a one word response like “prat” is enough to boost their ego enormously. If you respond, he’s won and you’ve lost.

If he’s a weak signal and is not effecting your QSO, then carry on as if he wasn’t there. Even if you go back with something like “you’re not making it so why don’t you give up” is enough to boost his ego. He’s won and you’ve lost.

Kerchunk jammers can only do it on a repeater that isn’t in use at the time. If it was being used then the kerchunk method wouldn’t work. The answer is as simple as the mind of the jammer, switch your radio off for five minutes. If he’s still there after five minutes, switch off for half an hour. If he wants to destroy his equipment by continuously keying it up, then let him.

It doesn’t really matter what type of jammer he is, the solution is always the same. Either ignore him or switch off. Don’t respond, don’t get into any sort of conversation with him, don’t be a weak minded moron yourself and get manipulated into his games. Just ignore him. If you do anything else, he’s won and you’ve lost.

You’ve spent a lot of time and money on this hobby, don’t let somebody else spoil it for you. You only become a victim if you allow yourself to become one. Don’t be a victim.

“Give a jammer enough rope and he will hang himself”.

North American Talkgroup has Returned to Full-Time Usage, not Just a Calling Channel

The biggest nonsense with DMR was that you could not have QSOs on the North America Talk Group and there were several repeater cops out of Florida trying to maintain order.

Now that is not an issue and with the ability to now have a QSO maybe the Talk Group will get more traffic as its been very quite lately.

The repeater cops may move their patrol radios over to the world of BrandMeister

North American Talkgroup has Returned to Full-Time Usage, not Just a Calling Channel


      DMR-MARC Network Users,


      Effectively immediately, the North America talkgroup (TG3) will return to its original purpose as a wide-area talkgroup available to all North American hams for general QSO at any time. We believe that the North America talkgroup is more effective as a meeting place for all hams, rather than only as a calling channel. Accordingly, we encourage all hams to use this talkgroup for general QSOs spanning across multiple North American repeaters as a way to bridge the distance between us. In addition, we kindly ask that hams respect the fact that this talkgroup is widely distributed and that they keep conversations to a reasonable length and take regular pauses to accommodate others that might want to join the QSO. Remember, User Accessible English 1 (TG113) and User Accessible English 2 (TG123) are available on many systems as talkgroups to continue your conversation if you feel that it is going to be lengthy in nature.


      Hope to hear you all on North America soon! Best regards & 73’s!


    The DMR-MARC Administrative Team
