Re: [Repeater-Builder] missing posts
I posted one message to the group Friday morning. I never got my copy as a subscriber. It IS there in the group's messages. In fact, on Friday, I never got a single message after 7am for the rest of the day. I got a few on Saturday and a few more on Sunday. Things seem to be back to normal this morning, but who knows. Even my regular e-mail was rather quiet. I wonder if it had something to do with Cinco de Mayo??? I'm sure that complaining to Yahoo will get the usual automated reply. I don't think messages were delayed; they were just never sent out. They seem to have that problem a lot.

Re: [Repeater-Builder] Portable Repeaters
Re: Crossband/Portable repeaters - Here in Colorado, we have two 2 Meter pairs designated for statewide use for portable/emergency/special event repeaters. These pairs get used to fill in the dead spots when emergencies occur. A number of clubs and ARES groups have portable repeaters set up on these pairs. (Good band planning by whoever put these in place years ago.) - Some of the emcomm folks use dualband transceivers with crossband repeat as a inexpensive way to extend radio range (often used to extend HT range from inside a building or other bad spot). These radios don't meet the letter of the law (FCC regs) with regard to identification (my opinion, you mileage may vary.) - We do not have any designated frequencies for crossbanding to 440 MHz in the bandplan.

To my knowledge there is no cut and dried FCC mandated coordination group for ham bands other then good practice.

Re: [Repeater-Builder] Portable Repeaters
Steve et al: The various amateur repeater coordinating groups have no official FCC authority or mandate to control spectrum or issue repeater pairs. As a practical matter, however, the FCC will almost always support a coordinated repeater over a non-coordinated one in matters of interference. This is in keeping with the FCC's mandate to prevent interference. Fortunately, the vast majority of hams are a cooperative lot and generally work with their local coordination group to keep repeaters from causing interference to each other. I have a portable UHF repeater on GMRS and one in the ham band and have used them where I live. So far, so good and no problems. By and large, the system works quite well. 73, Dick W1NMZ WPVY245 - Original Message - From: Stephen Rice [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: 08 May, 2006 08:04 Subject: Re: [Repeater-Builder] Portable Repeaters To my knowledge there is no cut and dried FCC mandated coordination group for ham bands other then good practice.

These radios don't meet the letter of the law (FCC regs) with regard to identification (my opinion, you mileage may vary.) I have one set up in my vehicle to help me get into our UHF system from inside a building. It uses a 420.something input and a 443.something output. I have a extra memory position set up on the handheld that listens to the system output and talks on the 420 channel. We are coordinated on that 420 channel as a link frequency and the receiver that hears that frequency is over 100 miles away and is on a directional antenna pointed at the mountaintop that the repeater is on, so it's not going to hear my HT inside a building. I'm the only one who is going to use that mobile extender and I am sure to ID it with through the WA6ILQ mobile repeater as needed. However Kevin has banned rules and regs discussions on this list for good reason - they generate a lot of heat and fire and discontent and nothing gets resolved - and this is getting close to that area so I'm going to drop the regs topic with this posting. Any regs followups to personal mail, or technical followups to the list. - We do not have any designated frequencies for crossbanding to 440 MHz in the bandplan. Most people just find some lightly used uhf simplex frequency. I've been known to use a repeater input frequency from some out-of-the-area system (with permission from the system owner) and use a different PL tone on top of that. For a long time I had a roll-around Pelican case (think of a Samsonite rollaround suitcase that's the width of a rack panel and a foot thick) with a 25w Micor mobile (switchable between the two local test pairs) with a duplexer, a Scom 7K and a Optima sealed battery in it. Roll it into a convention hotel room, stand it in a corner opened up for ventilation, hook up an antenna to the duplexer (a 6 mag mount stuck to the bottom of a metal trash can lid and hanging upside down from a top floor room balcony gets out a lot better than you would think). - If conventional transceivers are used, the power needs to be reduced or additional cooling supplied due to 100% duty cycle operation. A forgotten fact is that 25w Micor mobiles are continuous duty. - I constructed a crossband repeater using two transceivers and an NHRC-6 controller that knows how to handle the ID of two transmitters appropriately (most repeater controllers do not). http://www.nhrc.net/nhrc-6 A good tip - I'd forgotten that. BTW the -7 will also. - One issue with a vhf/uhf crossband repeat set up working into a repeaterthe repeater transmitter must drop before the crossband repeater can turn the link around. Shortening the hang time on the conventional repeater (or using CTCSS that drops with the received signal) helps this issue. We ran into that problem in one of the 1980s Rose Parades... I forget which year... the floats are built at over 15 locations and have to convoy in (some from 40 miles away) and arrive at the formation area in the proper sequence. Formation is on a city street and one float passing another is difficult - ever try and parallel park a 5-ton float that's 50 feet long and has a 300-degree blind spot? My assignment was at one of the float construction areas and could not get into the main parade control 147.27 repeater from there... I had a 440-to-2m crossband repeater in my car (at that time it was two HT-200s) and the guys at Parade Control had to wait for the system to completely drop out before I could answer a call. A while later another ham showed up with a 10w mobile and a gellcell in a backpack complete with an 18 spike antenna on a microphone gooseneck strapped to one of the shoulder straps. A few years later an outbound CTCSS encoder slaved to inbound COR was added to the repeater to support the crossbanders I wish that more repeater owners would add that. 73, Bob K0NR [EMAIL PROTECTED] Mike WA6ILQ Yahoo!

Re: [Repeater-Builder] Portable Repeaters
Ronny, It does not seem like a good idea to me to pop up on an untested channel(s) during an emergency. It would make sense to me to find a usable pair before the s**t hits the fan. Things are stressful enough in an emergency without trying to move both the repeater and then get all users to move without a large hole in connectivity. There is a good reason amateur emergency response groups practice _before_ they are really needed. Paul, One problem with the cross band approach is users with 440 HTs will need to wait for the two meter repeater drop delay to run out before they transmit. This also can be stressful in an emergency. You can get around this if you have the two meter repeater talkback encode PL only when the receiver squelch is open and then make the crossband box decode on two meters.

There are, of course, coordination problems with portable duplex repeaters and there is no apparent interest in agreeing on a wide- split pair of odd frequencies to avoid the conventional-frequency pairs. What experience has there been with the use of portable cross-band repeaters to enable hand-held units using a 440 MHz simplex channel to reach the portable repeater that will relay the message through to a two-meter fixed repeater?

RE: [Repeater-Builder] Portable Repeaters
Paul, When you push for a wide-spaced portable repeater pair on 2m, suggest a separation of at least 3 MHz. The reason is that you can buy compact base station duplexers that are specified for 3.0 MHz spacing, but the performance rapidly deteriorates as the spacing is reduced below that point. I bought a Celwave 5085-1 duplexer that was factory tuned to a 2.655 MHz split, and it works okay with a 10 watt R1225 repeater, but it took some tweaking. The entire repeater fits into a rugged fiberglass case that is less than a cubic foot in volume. I hope to complete the final version shortly. It will be a challenge to create a 3 MHz pair in only 4 MHz of spectrum, but it can be done. Let's not forget that the purpose is to support *temporary* communications of an emergency nature. While it would be nice to have a pair permanently set aside for this purpose, I'll bet that a true emergency will trump any other claim to existing frequencies. If the PL encode and decode tones are intelligently selected, any interference to established repeaters should be minimal to nonexistent. If the portable repeater is positioned in the area where radio comm is needed, low power works wonders! 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Paul Yonge Sent: Monday, May 08, 2006 4:59 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Portable Repeaters Mike - What a batch of good ideas!

Re: [Repeater-Builder] Portable Repeaters
Eric - Thanks for the comments on duplexers. When I started this in January, I remember reading some comments about some duplexers getting out-of- tune from bouncing around (mainly in shipping) and that's what got me thinking about simplex repeaters and, now, about cross-band repeaters. Is subjecting the duplexer to vibration and shocks in a truck on a rough road really something about which to worry? One of the comments I received when I proposed using simplex repeaters was that, if a fixed-repeater went off the air because of power failures, it would be possible (with the permission of the repeater owner/trustee) to tune the simplex repeater to the fixed- repeater frequencies as a temporary measure until the fixed-repeater could be returned to service.

Re: [Repeater-Builder] Portable Repeaters
Nate - You did a great job of answering the question I posed to Eric before I read this. Parking a standby itinerant repeater on a pair of frequencies that are temporarily down due to the emergency does make a lot of sense. Hopefully this discussion will spark some inter- association cooperation and exercises. In an emergency, hams in the area may have serious problems of their own that demand attention and the solution to communication problems will be resolved by hams from neighboring areas who move their time, talent, and equipment in just as volunteer firemen move up to man vacant fire stations while the local firefighters are busy elsewhere. Your comments about preparedness are right on the mark. I took the trouble to become a certified planner in connection with my NYSDOT career but I know a lot of other planners who ought to be certified (and not with the AICP designation). A week or so ago, I had almost decided to forget about providing a standby repeater of some sort in my Sprinter ARK but this discussion has revived my plans and I'm very appreciative of the response from all you experts. My telecommunications background goes back over fifty years in the telephone business where I worked on a lot of magneto crank phones and step-by-step dial systems and I've only been a ham since January when some other hams scoffed at my idea of furnishing a GMRS repeater that volunteers who were not hams but had access to some bubble-pack hand-helds could use. You folks have come up with a lot of great ideas that I plan to discuss with the repeater coordinators and I need all the help I can get. Thank you all!

RE: [Repeater-Builder] Portable Repeaters
Paul, Full-size BpBr cavity duplexers can easily be detuned with rough handling, especially when the box is dropped on its side- which puts sideways shock loads on the center tuning element. Notch-only duplexers of the mobile type are, by design, far more resistant to vibration and rough handling. The Celwave 5085-1 duplexer I cited is a notch-only duplexer that is about 50% larger in all dimensions than a typical mobile duplexer, but it should be nearly as rugged. I don't expect this portable repeater to be bouncing around in the bed of a pickup; it will likely be strapped to a shock-mounted storage shelf in my RAV4, along with magnetic mount antennas and a telescoping mast. A simplex repeater on an existing repeater pair is an excellent idea. I already have one in service, being tested on a coordinated pair assigned to me. It is a Motorola SM50 VHF radio connected to a Zetron 19B Simplexor simplex repeater controller. It listens on the repeater input frequency and plays back on the repeater output frequency. A Comm-Spec ID-8 performs the identification functions while the repeater is in use. It gets used a lot by Hams who want to hear how their radio sounds. I will be the first to admit that a simplex repeater (isn't that an oxymoron?) gets to be tiresome to use real fast, and some users get annoyed by hearing everything twice. But, hey, in an emergency it works. One of the posters commented that it would be chaos while everyone tried to reprogram their radios to the special wide-split portable repeater frequency. Not! The majority of the Hams who will use this portable repeater are fully-trained ARES members who test their equipment on a weekly basis on several nets, and all of their personal radios are pre-programmed. One of the local ARES groups has a cache of Motorola HT750 portable radios which are already programmed with every local repeater, including the wide-spaced portable. We take emergency preparedness seriously in my neck of the woods, and we don't expect or need to have a sudden influx of clueless people who don't know how to program their own equipment. It is a requirement that each ARES member have in his or her possession a valid Disaster Services Worker identification badge issued by the County Office of Emergency Services. Mandatory refresher training, including CPR, is routine. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Paul Yonge Sent: Monday, May 08, 2006 6:20 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Portable Repeaters Eric - Thanks for the comments on duplexers.

Re: [Repeater-Builder] Portable Repeaters
Eric - Thanks for the education on duplexers. I had planned to stow the repeater in a Pelican case but some of our New York roads are a little rough especially if we're looking for a high point in the vicinity of an incident. Your comments on preparedness are well- presented. If we want to do a job right, we need to plan and train and practice Well, you've gotten me all fired up again on the simplex repeater idea. Hearing everything twice isn't a bad idea. In the telephone business, we solved a lot of operator problems by service observing that consisted of recording a sample of each operator's calls and then calling them in and asking them if they'd like to hear what they sounded like before we erased the tape. We didn't need to say a word and the look on each operator's face as they said Oh, no! or Is that what I sound like?' or Did I say that? showed it was the best training they could ever get.
