[Repeater-Builder] question for commercial radio shops
If a person whom you knew and is involved in a number of church youth camps activities asked you to program FRS frequencies into a 4w UHF HT type accepted for LMR would you do so ? It would only be for extended range at camp. My gut is to tell him no... Sorry for the slightly off topic postI just need a little extra thought on the subject... Bad thing is the person asking is the captain of my Volunteer FD. 73, Jon
Re: [Repeater-Builder] Opening Salvo
'retuned as receiver'..may be that it is tuned elsewhere and it was just a radio laying around to be used as a inexpensive receiver...by no means does it imply it is being used on FRS frequencies.

Re: Poor Mans Repeater Project anyone? Would some of you group members be interested in a Poor Mans Repeater Project as described below? The project goal would be to construct a simple repeater using various/mixed radio parts. We as a group would talk about various portions of the repeater during actual construction of a project by at least one or two (probably more) group members. The project would more likely be surplus two-way conversion and/or ki-built related radio equipment as anyone can buy a pre-made repeater system. We'd toss around a few ideas first and then try to aquire equipment and make it work as best possible. Converted mobile radios..? Converted base or commercial repeaters? Junk bought off ebay... yadda yadda. Duplexer... no duplexer, high power, low-power. You get the idea... Might be fun and a way to get good information and various opinions out to the group. A lot of you don't have the money for some of these bells and whistles we talk about. So why not go back to our roots and build a repeater from scratch. Anyone interested? cheers, skipp Yahoo!

Re: [Repeater-Builder] Hand Held radios as repeaters
I did something of the sort using FRS radios on a hunting lease
where terrain did not allow everyone to communicate with
each other. I tied the audio out put of one to the mic input
of the other and vice versa.
They were set in VOX mode and each radio was set to a different
channel. One group set their radios on one channel and the other
used the other channel.
The repeater was seperated by about
3' vertically. It was simple and cheesy but it worked.

Thanks Eric,
It will be for experimental purposes mainly with a fairly low duty cycle. I
was looking at the UHF 470Mhz band because I can get radios cheap for those
freqs. I am not sure about the seperation I am not interested in large
power outputs, I am looking at 5w max.

Greg,
Is this going to be used for commercial or Amateur purposes? What frequency
band? What separation between TX and RX? Is the repeater intended for
casual, low-duty-cycle purposes such as a family reunion or for
high-duty-cycle purposes such as emergency support? The answers to these
question will be helpful in guiding you to a solution.

Subject: [Repeater-Builder] Hand Held radios as repeaters
Hi!
I want to build my first repeater using 2 hand held radios mounted in
a Pelican case with a gel cell for power.
I have no idea where to start or what is required to build the
repeater. Can anyone give me some ideas on connecting the radios? So
far I think I have to get 2 radios, case, battery. Do I need 2
antennas or should I use a duplexer. I want this setup to be as basic
as possible.
Thanks in advance

Why so dumb and so-backwards? Consider thisMy car with ham call letter license plates was stolen. Thru QRZ.com as an example, the thief can figure out where I live and get a good idea of my other interests just by looking inside the vehicle and truck. They had master keys for the door and ignition so opening the trunk would not be a problem. He now knows where he can get lots more goodies for free. And with Pretrial Intervention and Plea bargaining he knows he will not be duffely punished if caught. So put your ham gear inside your car with your tools, other hobby interests and your call letter license plates on the bumpers and announce to the world here is a sample, stop by my house for more free stuff. Gary K2UQ You misread my comment. Please read it again. I said the number of cars WITHOUT call plates and antennas could be counted on both hands. I thought this was NEAT! As far as cars and rigs: Theives can steal anything they want out of a car. Cars aren't secure in the slightest. (I've had my Jeep broken into three times, trust me.) I've known hams who've had call plates and radios in all their vehicles for over 40 years who have never had a problem, and I know hams who've hidden everything in their cars and had rigs ripped off. It's not predictable that call plates mean anything in how thieves pick their targets. In fact, it probably has a lot more to do with WHERE you park your vehicle than anything else. All of my breakins were within three blocks of a bus station and a homeless shelter. Outside of my time working in that area of town, I've never had a problem. The opportunity costs lost to paying for rig insurance must be worth the convenience of getting it replaced anytime to you, or you run your risks and take your chances, just like everything else in life. And the standard financial/fiscal rule applies: Buy assets, not liabilities, whenever possible. Anyway, this isn't repeater related anymore... The FCC posts all of our addresses publically -- one of the risks we take of being hams. The FAA long ago allowed pilots to remove their public information -- The FCC doesn't appear to want to do it.

Re: [Repeater-Builder] Dual Band Handie Talkie
The AT-600 was programable in the 2m/440 range as well as commercial and gmrs bands. It could be opened up well beyond that...of course then type acceptance probably goes outthe window. The HTX-204 was based on the AT-600 but only has a subset of the menu functionality that the AT-600 has. The case is similar and batteries are interchangable although the differences in the case make the batteries look mismatched. The HTX-204 also could be opened way up and that is why it was pulled from sale a couple of weeks after it hit the shelves.

I co-moderate a group whose subject is just that hamgrounding It is currently a small group with low to moderate traffic. Please feel free to join and keep discussions on topic. http://groups.yahoo.com/group/hamgrounding I know there are people in this group(repeater-builder) that have lots of knowledge and experience in this area. I would like to especially ask them to join the hamgrounding group in order to help share their experience. 73, Jon KD5SFA Thanks Bill for letting me post this Yahoo!

Re: [Repeater-Builder] Ho! Ho! Ho!
Wouldn't that be Yo! Yo! Yo! G Anyhow back on the topic of repeaters.. I lurk quite a bit here and over on the AR902 group and I am in the process of gathering the pieces and parts to put up a 900Mhz amateur repeater. I am trying to locate a relatively inexpensive 900 Mhz continous duty amp to be driven by a Maxtrac exciter as well as a source for a duplexer. I already have the maxtracs for use and the filters. I just need to do the VCO mods , replace the filters, and build my interface between the units. I have access to heliax and a 900mhz commercial repeater antenna for use...maybe even two. Any recommendations on where to find the amp and duplexer on a budget ? 73, Jon KD5SFA -Original Message- From: Ken Arck [EMAIL PROTECTED] Sent: Dec 3, 2004 11:31 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Ho!

Re: [Repeater-Builder] [OT] Current draw of 2 meter rigs?
If you use an HT you can use a speaker mike and an external antenna. A good external antenna with 5 watts is going to do more than a good duck with 5 watts. Secondly a 7AH gel cell will run it all day long at full power. If you have to have more poer just carry a second 7ah gell cell and run a 35 watt brick amp. That still keeps a fairly small package that is not too heavy. Also the HT could be mounted with a cell phone type of pedistal mount. A mobile may draw as much as 12 amps or more at full power (50 watts). If you only run at 5 watts you are having to carry more weight/bulk unless you have a FT-1500m which is small. Just a few things to think about. 73, Jon KD5SFA -Original Message- From: [EMAIL PROTECTED] Sent: Nov 17, 2004 9:21 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] [OT] Current draw of 2 meter rigs? I have a notion to put a VHF radio on a bicycle for public service work, and am wondering if anyone on the list has any better current draw numbers than those at http://www.arrl.org so I can pick the radio that will require the lightest batteries. The problem with a radio on a bicycle is there is no way to top off the batteries en route except with a solar panel or with an unregulated fork-mounted dynamo normally intended to drive a 3- to 6-Watt bulb. A solar panel big enough to be useful (especially here) would be big enough to make a dangerous sail if the wind blew and the dynamo, in addition to creating whine in use, would not deliver enough charge current to keep the battery up when in use. I do have a pair of 12 AH AGM cells on hand that could be pressed into service; with that as a given, I want to maximize the length of time I can operate from one or both cells or, alternately, use a smaller battery or pair of batteries for the same run time. I suppose I could use a HT for this purpose, but they do have certain limitations I would like to avoid if possible. The biggest limitation is the antenna mount; the second biggest is the low gain of the stock rubber duckie and its replacements. Since strictly speaking this is off topic, please E-mail me any responses at [EMAIL PROTECTED] or my callsign at the same ISP. de kg7yy Yahoo! Groups Links Yahoo!

Re: [Repeater-Builder] wild band opening
Probably due to some good tropospheric ducting in that region Check out this website...This guy seems to have it figured out and is usually correct with his predictions. http://home.cogeco.ca/~dxinfo/tropo.html 73, Jon KD5SFA -Original Message- From: Q [EMAIL PROTECTED] Sent: Oct 12, 2004 10:43 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] wild band opening From Erie Pa I am hearing repeaters from Michigan,Ohio and Ontario I dont usually hear on 2 and 440. I also noticed while looking at NWS radar images that they all have a huge ,colorful flare that appears to rotatae around the radar site.Anyone know if they correlate? Look at Cleveland,Detroit and Buffalo images...wow! Maybe its a lake duct type opening,its different than the normal band opening. What is it? Yahoo! Groups Links Yahoo!

Re: [Repeater-Builder] Re: 6M duplexers using C02 bottles ?
They use steel tanks for scuba...although most everyone has converted to aluminum for various reasons. The point here is that on the steel tanks, if there was rust and/or pitting you would have to have them rolled. This is where you fill it with gravel of a specific type and roll the tank on it's side so the gravel wears away the pits and rust leaving a clean surface. I believe the procedure is used with the scba tanks the firefighters use as well. 73, Jon KD5SFA NAUI certified 1983 -Original Message- From: ka0ies [EMAIL PROTECTED] Sent: Mar 15, 2004 1:04 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: 6M duplexers using C02 bottles ? I would recommend going at this rather carefully. Where I used to work we had CO2 piped in around the plant in liquid form and they did it in steel pipe. Whenever someone would make a new connection to the valves in the system it was normal to blow out the crud from the lines before making the connection. It turns out that in the liquid form the CO2 is somewhat corrosive to the inside of the pipes and the valves being the low points in the system would collect all kinds of rust and other debris that was traveling in the system. I guess what I am saying is open up one of the tanks and see what condition the inside surface of it is. It might be rough and rusty and not feasible to clean up and silver plate. Yahoo!
