Re: [Repeater-Builder] Re: Circular polarization for VHF repeaters?
HI to all, I guess that I do not have much to contribute on this thread but to me it is very interesting reading. Gary has my sympathy, his problem is duplicated here. Much of my repeater work relates to a low power portable repeater on 141 MHz. We live near a medium sized mountain range which has plenty of deer and wild pigs. Hunters go looking for them and perhaps get lost, or fall and break a leg. Also, there are recreational trampers who just get lost . Several times a year we have to go find, and rescue them. The last time was two days ago at 6.30 am. For once, it was not raining! Our repeater runs 5 watts output, needs to run three or four days off a gelcell, and most importantly has to fit into a backpack to be carried to a convenient hilltop. Fortunately, the split is 3 MHz so that the duplexer is of a reasonable size. The problem is getting reasonable coverage. Sure the search areas are fairly small but usually encompass several ridges and deep valleys. We use vertical polarisation with a 5/8 whip on the repeater and the search teams have flexible dipoles that fit into their backpacks. Sharp ridges and steep slopes contribute to coverage problems. Would circular polarization help?? I think not. Gordon ZL1KL Tauranga N.Z.

Re: [Repeater-Builder] Adding capacitors to lower electric bill
Another quirk. Sixty plus years ago in England, power factor was not the main concern. Many of the domestic radio receivers were transformerless and used half-wave rectification to obtain D.C. for the tubes. A consequence was a fair dose of D.C. flowing in the street power mains.

[Repeater-Builder] Re : Astron Power Supplies
Hi Jim, I have following this conversation thread over the past few days and note your comments about overcharging. I have been through this situation and settled on a solar panel charge controller. The unit I am using uses a MOSFET to do the switching and a hefty Schotty diode to isolate the battery. The 'charged' voltage is adjustable - in my case it is 14.4 volts on a bank of SLA's. The hysteresis can be preset so that the charger is not turning on/off every few seconds. Gordon ZL1KL Tauranga N.Z.

Re: [Repeater-Builder] Re: Repeater Kerchunk
I agree with this - example being that there's a repeater that's fairly distant to me (easily managable from the house, but quite difficult from a car until I'm about 10 miles closer to it than I am at home). There's also 2 repeaters that are really distant and can vary depending on conditions. All 3 of these repeaters operate as mentioned here - If I key up and let go, there's a tiny bit of carrier as I unkey. If the carrier's too badly broken, I don't give my call, as it wouldn't make it in anyway and would just be plain annoying. One of these repeaters needs a fairly long over before it actually opens fully and IDs itself. New users (including myself at one point) find this annoying, thinking that it's not working. I still forget occasionally to length my call by giving it in phonetics, and have to re-do it to make it long enough to open the repeater. The local UHF repeater opens fully at any 1750Hz tone or CTCSS on the input, which means someone kerchunking it, or not making it in fully, results in 10-15 seconds silent carrier and the full ID every time (It's nearly 2KHz off frequency too, but that's just it's age!). By comparison, the last repeater round here to not have CTCSS is a complete pig to open - deliberate or otherwise - and this results in virtually zero use. Geert Jan de Groot wrote: We have some on our repeater frequency, that just like to kerchunk the repeater to hear it come back or ID. Is there any way we can eliminate this annoying situation? I suspect that we may have an unlicensed individual with a 2meter radio. This actually isn't technology, it's psychology. Consider this: A guy, either licensed or unlicensed, got himself a radio but doesn't have lots of reasons to get active, either because he does't know the crowd, is new, perhaps not licensed (yet!) or just because he wants to test access to the repeater. You and I, each with more than 20 years of experience, know what to expect; for someone new, this is cause of concern and something to explore. Asking for a report may be difficult - perhaps because he doesn't know the group of people that all seem to know eachother for years, perhaps he looks up to the user community, perhaps the license thing sits in the way. The easiest way to get what he wants, is just to kerchunk the repeater. So that's what he does. There are 4 things to do: 1. Make the kerchunk event as non-disruptive as possible. Make sure the repeater's response is there, but as non-intrusive as possible. My machines just have a 500 ms hangtime; if people kerchunk, they just hear the plop when they unkey, know that the repeater still works, and be done with it. Certainly, no roger beeps, bloops, ID's or significant hangtime. Just enough response to allow for testing and be done with it. (Dutch regulations allow me to periodically ID; hence, I don't need to make this dependent on user activity and, as you'd guessed, the ID thing is completely independent of activity, be it kerchunkers or regular users). 2. Believe it or not, make kerchunking easy. One of the machines I manage, used to have a speech detector. Kerchunkers, instead of quietly keying the microphone, were supposed to ID. They were supposed to, but what happened was that people would whistle, rub the grill of the microphone or do something else to circumvent the speech detector. When the machine got renovated, I removed this misfeature, allowing just plain carrier, and the user community picked it up quickly, supposedly because the other machines work like this. Again: kerchunking is going to happen. Make it easy, minimize it's impact, and make it a non-event and be done with it. 3. Don't talk about abuse issues. Never, ever, mention the kerchunker. This, and the rationale behind it, should be known to members of this group; check the abuse files for the reasons behind it. 4. Create a friendly, inviting environment where newcomers feel themselves welcome. With luck, the kerchunker(s) will join the community and become a valuable addition to your user group. I know this has happened several times on my machines, and I do consider this a feature. 73, Geert Jan PE1HZG janitor, PI3EHV, PI2EHV, PI6EHN, PI8EHV No virus found in this incoming message.

This is to be expected from a country that managed to vote George W bush into power twice really.

Anyway, From the quick skim I've had here, Here's what I've read: The TV channel named Channel 7 is/was on VHF channel 7. It's also now on UHF channel (30?) So it's not long ON channel 7, altough it's CALLED Channel 7.

I hope nobody goes to a lot of expense to optimize an antenna system for these interim channels.

Each state is just like it's own country anyway - it's own laws, taxes, etc. Don't see why organising some radio transmitters seems like such a big deal - apart from that the US never made the jump to UHF, and buy the sounds of it, hasn't given itself proper preparation for Digital TV either. Don't see why someone who knows about radios should find it so difficult to understand that the channel number displayed isn't always the channel matching the frequency the transmission is actually on.

[Repeater-Builder] Micor Repeater
It has been suggested that before one adds a controller to the repeater it is best to have it repeat in it's original configuration. This unit was part of the VHF Provincial Mobile Telephone system and in its present form I can get it to repeat only after dialing the code that puts the transmitter on continuously. Eventually after being quiet for a time (no COS) the transmitter times out and you have to dial up to get it to operate again. Presently it has the following cards installed, left to right, Decoder filter STLN89HDT, TC Logic, Logic Module STLN932, Squelch Gate TLN4662A, Jackfield Module, Time Out Timer TRN8684A, Tel. Interface, Station control module TLN4635B, Line Driver Module. I am sure there is a reader to tell me that most of this stuff can be pulled out and a jumper changed here or there will get it going in a normal fashion. I hate to put a quick and dirty COS gate and relay on the Back Plane when a simple change to a plug in module will get it going. Receiver and Transmitter tuned up on the 144/145 band perfectly. Lots of good reading on this site, thanks for this opportunity, 73, Gordon.
