RE: [Repeater-Builder] Repeater Kerchunk
If you’re getting “washed out” by your repeater ID, you definitely bought the wrong controller or have it programmed wrong. :-) It shouldn’t be ID’ing as soon as it comes on the air, it should ID on the UNKEY event after the kerchunk.

RE: [Repeater-Builder] Repeater Kerchunk
We've successfully used the S-COM variant of this for years, here. anti-kerchunk set up correctly, works fine. (That is, it's NOT active until the repeater has been IN-active for quite a while.) The reality though is that it just trains the kerchunkers to do longer kerchunks. The problem doesn't really go away, but at least you know it's a valid signal (with CTCSS decode on at the repeater site), and it gives you a longer transmission to DF, if you're really interested and care. most of the time, no one does. Mixing the activation of the anti-kerchunk with a voice ID from the repeater at least gives the kerchunkers something to listen to, since the majority of them are licensed hams looking to see if they can "hear the repeater". This seems to minimize CONTINUOUS kerchunking. they do it once, get a very long voice ID back, and they're "satisfied". Some people are just morons who can't be bothered to take a moment to say their callsign once or even more politely, saying their callsign and "testing", instead of just kerchunking illegally. You can't fix stupid. All you can do is set up your repeater controller to make being stupid, really annoying for the stupid guy. As someone else pointed out, if you build the repeater to act more like a commercial system with CTCSS only transmitted on real user input, no one hears the transmitter "tail" and kerchunks are really boring for anyone running CTCSS decode. you hear a click, and that's it. Kerchunkers are just a part of life when you run repeaters, basically.

Re: [Repeater-Builder] Repeater Kerchunk
When I make a transmission on a repeater that hasn't been used for a while, I state my intent and call sign, and the repeater ids after I let go of the PTT. I have made a legal transmission, I gain the information that the repeater has been dormant, AND I know that my transmission held the COR/CTCSS for the entire duration of my transmission. That tells me more that just hearing the hang time of a maybe partial reception of my signal. New hams learn by the example of existing hams. If you are making unidentified transmissions, they will make unidentified transmissions. whensle...@comcast.net wrote: > > > My thoughts would be... let it be.

Re: [Repeater-Builder] Repeater Kerchunk
Anyone listened to the latest Gordon West, WB6NOA audio CDs for the tech class license? Happened to sit it on a tech licensing class a couple months ago... If I recall correctly, the verbiage he (WB6NOA) used while demonstrating repeaters was "first, we'll key it up to see if it's on"... I'll have to grab that particular CD and listen to it over again - the 90+ minutes on just repeater operation tends to make me glaze over... If Gordo is teaching that kerchunking is OK :) And from a legal standpoint, 97.119(a) states "... at the end of each communication, and at least every ten minutes during a communication...". While a "communication" is not clearly defined in 97.3(a), it could be surmised that it would be in the course of a conversation in which two Amateurs exchange information for as long as the "communication" continues until that "communication" comes to a close. Reading very loosely between the lines, if one kerchunks the repeater 7 minutes before a net starts, and subsequently properly identifies during the net check in prior to the elapsed 10 minutes, they *could* be fulfilling the identification requirements set forth in 97.119(a). HOWEVER... It is likely not good amateur practice or etiquette to do so. On the flip side of it, I'm not going to send a FSD-213 for someone that occasionally kerchunks the repeater prior to making a contact or verifying their radio is programmed correctly. I will, however, continue to treat malicious interference as a prohibited act as defined (loosely) in 97.101(d). 73s, AJ, K6LOR/R On Mon, Mar 16, 2009 at 8:39 AM, Joe wrote: > Legally, you should be identifying by giving your call.

Re: [Repeater-Builder] Repeater Kerchunk
Legally, you should be identifying by giving your call. But, that is inviting a conversation with whoever hears you. One of the repeaters here has a ham who hangs around constantly. Sometimes I chose not to talk to him, but just want to check and see if the repeater is on the air and OK. (I help maintain the repeater). Yes, I am guilty of illegal kerchunking. An antikerchunk filter that shortens the repeater tail time can make things worse. The kerchunker does not hear the tail come back to him/her, so they keep on trying. All the other users hear many short bursts of carrier. Much more annoying than a single kerchunk. I actually like to hear kerchuncks. That means that there are users out there tuned to my repeaters. With so much dead air time on repeaters lately, it's nice to know there is "someone home" out there.
