[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: [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. -Original Message- >From: Greg <[EMAIL PROTECTED]> >Sent: Jan 30, 2007 7:26 AM >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] Hand Held radios as repeaters > >Thanks Eric, >It will be for experimental purposes mainly with a fairly low duty cycle.

Re: [Repeater-Builder] Radio Shack store closings
Yes it does help to direct comments and suggestions to the corporate masses. Being that I work there it is hard to get with the people that make the decisions. Just as a note, the below mentioned email address doesn't conform to the normal coporate standards so I do not know if it will bounce or not. Just bashing the shack doesn't help eitherit's a two way street. Hams stopped buying parts so they had to scale back because there was no longer any profit in them. Then the hams started bashing them for not carrying them. Then you need to include the overall change in technology...more things are available without the overhead of a store...so everyone is going to the internet. Thus you can't just blame Radioshack.

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.

Re: [Repeater-Builder] Ho! Ho! Ho!
Wouldn't that be Yo! Yo! Yo! 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.

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.

RE: [Repeater-Builder] Lightning Protection
Wouldn't a stranded copper wire do better in the event of a strike ? If I recall correctly, lightning has a fairly large AC component and likes to travel on the surface of the wire (Skin effect). Thus by having stranded wire, it could carry a larger current to the ground because you would have more surface area for it to run along. A number of people I know run 2/0 and 4/0 stranded copper from their tower legs to their grounding systems for that reason. 73, Jon KD5SFA -Original Message- From: "Daron J.

Thanks, that is a good idea. Just to clarify though, exothermic requirements refer to cadweld type connections, the other requirements are 'irreversible crimp' which refer to the sleeve or tube that is crimped and cannot be taken off.

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!
