Re: [Repeater-Builder] 2 Meter VHF Preamp
Mathew, The choice is usually between bipolar and GaAsfet, and depends primarily upon the noise level at your repeater site. Sometimes, reception can be improved more by using a higher-gain antenna and/or a lower-loss feedline, than by adding a preamp. In any case, the best results are achieved by adding a sharply-tuned bandpass cavity filter between the duplexer and the preamp. Otherwise, the preamp will amplify a lot of noise along with the desired signal, and is very vulnerable to overload. An excellent tutorial on preamps is at: http://www.anglelinear.com/repeaters/repeaters.html 73, Eric Lemmon WB6FLY w9mwq wrote: What type of preamps are available for VHF to enhance the receive of a repeater?

Re: [Repeater-Builder] Station master antennas
Western PA, and Stationmasters, Superstationmasters, and clones made by several other companies. The best built was made by Telewave, but still had the same problem after some time. All were top mounted, so supporting the top of the antenna was not an option. I've seen it on several dozens of them. There is a 'small' multinational tower company in my area who uses nothing but dipole antennas for the same reliability reasons. Yes, stationmasters are more numerous than the others, but how many are on repeaters? In my area, most PS systems are not full duplex. This is duplex noise, so it won't show on half duplex or simplex systems. It also won't show on UHF. Apparently, they give more in the wind. I can't say I've seen the same problem on a single UHF stationmaster. Of all the stationmasters used in my area, probably less than 2% are on VHF repeaters. In fact, in one county near me, EVERY VHF repeater in the entire county with a stationmaster has had this problem (all were top mounted, FYI). If you replace it with another, they are problem free for 6 months to a year, then develop the same problem again. Of course, just because something is popular doesn't make it the best. Joe M.

Re: [Repeater-Builder] Station master antennas
Yes - even after the ice thaws. Granted, it's much easier to see a fiberglass antenna after the ice, but that's because they are frequently on the ground if they get too much ice - especially when accompanied by wind. It's not THAT bad, but dipole type antennas do survive the elements much better than fiberglass antennas. And if it's for a VHF repeater, stay away from the fiberglass antennas. They develop cracks that create a ton of duplex noise. The elements are too long to flex in the wind, and they create cracks at the solder joints. Joe M.

Re: [Repeater-Builder] Re: 802.11b wireless
Nate is correct in that the frequencies listed were the center freq of each channel. There are 14 channels. And yes, I forgot the decimal. Oh well I am old as well as tired. The channels overlap each other in that they are 22 MHz wide ( NO decimal) One can do the math and see which channels edge falls outside the Amateur band if you wish but if you do not run an amplifier, who cares. If my memory serves me 802.11 concept began in the late 80's and there were two forms approved by the FCC. One was DSSS (Direct Sequenced Spread Spectrum) that is used today and the other was FHSS (Frequency Hopping Spread Spectrum) that consisted of 75 channels spaced 1 MHz apart and traffic jumped between those channels. In 1999 the industry selected 802.11b as the standard with its max 11 Mbps. Of course we now have everyone pushing the 802.11g that have a maximum of 54 Mbps but we seem to forget that many access points use 10 base T Ethernet connections so you are limited to 10 Mbps anyway. Remember as the signal gets noise due to low signal strength the speed is decreased. I use 802.11g but often have only Mbps speed due to low signal strength. Still pretty fast as I have seen T1 that was only slightly higher is speed. With a good antenna it possible to get amazing distance. I have sent video with p1 picture to my brother Jim,KA8HAK over in Akron 16 miles from me. I was using 1 watt into 140 feet of 7/8 hard line to a 3 foot dish at 85 feet. He was using a home brew 44 element linier yagi on a tripod 7 feet in the air fed with LMR400! Until last year I had an FM repeater (2.411200 out / 2.431200 GHz in) on the air. It also ran 1 watt and had a 20 meg split. Worked pretty good but there were only three of us that could transmit. Jim KZ5AW, my brother Jim KA8HAK, and myself. Perhaps one day I will put it back on if equipment become more reasonable and others become interested. Oh well - enough of the rambling and at least I said something about repeaters.. 73 P.S. Nate, I am glad I gave you a laugh at the no decimal. One of my goals is to make someone laugh each day even if they are only laughing at me! It was a good day as is most of them..

That channelization map only shows the CENTER frequency of the direct-sequence spread-spectrum channel you're using. I believe Mr. Reese is incorrect in his statement that channels 7 and 8 are in the ham band. Each channel overlaps the channels around it -- they're wide. (Our old pal Nyquist's pesky theorem might point out that there's not enough bandwidth between from say, 2417 to 2427 to do a 11Mb/s data stream on Channel 3, and that's assuming you would run right up against channels 2 and 4. But, I sure as hell can't do the math without having had any coffee yet today!) The access points just deal with the interference they cause each other. When you're laying them out for use in an office building, you pick patterns that use 1, 6 and 11 to keep all the AP's out of each other's hair. Channels 1, 6, and 11 are the only channels that don't overlap each other in the U.S., so channel 1 extends up through Channel 3 (and below channel 1 down to just above 2400 MHz), and Channel 6 extends downward to Channel 4 and upward to channel 8. So the highest usable channel if you want to operate as a Part 97 station is Channel 6 if I didn't screw up my math. Or the top portion of your signal will be out of the ham allocation. ;-) I got a kick out of the 24XX GHz label too... that's pretty high! (GRIN) Nate WY0X JOHN MACKEY wrote: It should be noted, also, that the channels are overlapping on each other. The only channel setup that would NOT be overlaping it using channels 1,6, 11.

I can't say I've seen the same problem on a single UHF stationmaster. I have. In fact, a defective UHF Stationmaster generated noise that re-radiated into a VHF antenna next to it. The VHF antenna was a Hustler G7. Both antennas were receive-only. Once the Stationmaster was replaced, the noise on the VHF system went away. Bob NO6B Yahoo!

--- Yahoo! Groups Survey --~-- Please help us to improve Yahoo! Groups.

The antennas are a simple J pole, a Hustler G7 ---144 and a small triband vertical. I know that none of these have much to offer and I am now in the market for a proper commercial repeater antenna but just the same, what is my problem?-only the J pole works acceptably. VSWR on all antennas using the repeater signal reads unity or very close to it between duplexer and antenna feed line, distant transmitt signal strength measurement sees the Hustler a bit stronger and they all receive a distant weak signal (repeater transmitter off) about the same (maybe the Hustler is a bit better). What I'm saying here is that all three antennas seem to work about right for what they are except that I get serious desense on two of them---30 watt transmitter, a two stage isolator in place, 6 can P-D duplexer and about 20 watts into the antennas no duplexer tuning between antenna changes.

Re: [Repeater-Builder] Remote Receiver's Dumb Question
What you should do is have the remote reciever have a VHF transmitter into the VHF sides RX. What you do then is run the remote RX on the opposite offset to the repeater. For example when the user wants to come in on the remote, he switches to the + offset instead of -. You would need to build a VHF repeater with a 1.2 MHz split, allowing you to use commonly avalible commercial duplexers meant for 1.5 MHz splits with a little less attenuation. Or run the transmitter into a beam aimed back at the repeater and the RX on a Omni. Although the Federales don't like auxilliary use on 2M, so you will either need to call it a remote base, or transmit into your UHF side instead and keep the VHF rx still on the opposite offset, On Fri, 10 Dec 2004 11:16:22 -0800, Mathew Quaife [EMAIL PROTECTED] wrote: I'm thinking the echo thing will come into effect.

Well as for priority, you mean between the 2 meter and 440 repeater on the controller. Not sure if the Cat 1000 has the option, if the 2 meter is keyed up, so is the 440. The 2 meter will be the primary in the system. The remote receiver/transmitter will be about 15 miles away. Mathew Mathew Quaife wrote: I'm thinking the echo thing will come into effect.

The CAT 1000 SHOULD have a programming parameter that allows one to over-ride the other. Which one you pick is up to you. I would say that the one that hears the most people the best should take priority. -- Jim Barbour WD8CHL Yahoo!

Re: [Repeater-Builder] Remote Receiver's Dumb Question
Ok, now I understand what your getting at. That should make it easy. Will give that a shot and see what it does.

DCFluX wrote: What you should do is have the remote reciever have a VHF transmitter into the VHF sides RX. What you do then is run the remote RX on the opposite offset to the repeater. For example when the user wants to come in on the remote, he switches to the + offset instead of -. You would need to build a VHF repeater with a 1.2 MHz split, allowing you to use commonly avalible commercial duplexers meant for 1.5 MHz splits with a little less attenuation. Or run the transmitter into a beam aimed back at the repeater and the RX on a Omni. Although the Federales don't like auxilliary use on 2M, so you will either need to call it a remote base, or transmit into your UHF side instead and keep the VHF rx still on the opposite offset, Generally not a good idea-you wind up with a repeater input on a simplex frequency, or another repeater output, or possibly in the satellite band (145.80-146.00). A few wind up on other repeater inputs (145.41-145.49 give you 146.01-146.09). -- Jim Barbour WD8CHL Yahoo!

[Repeater-Builder] duplex through lmr-400
Duplex Operation through LMR400 type coax should not be considered the cause of a problem. Many of the reported foil shielded coax problems can and do happen in base station (simplex) operation. cheers, skipp www.radiowrench.com Scott [EMAIL PROTECTED] wrote: ...

Here goes: I have a two meter repeater that has a 440 repeater tied to it. What I want to do is take a vhr receiver and a uhf transmitter going in on 2 and out on 440 from a remote site that will have a beam on 440 back to the repeater. Trying to avoid using different PL's, and escape the expense of a Voter system, how would the repeater act if the user was getting into both the remote 2 meter receiver as well as the one tied to the repeater? Would the receiver with the strongest signal override the weaker one, or would there just be plain havack on there. What are some of the thoughts. Mathew Depends on how your controller is setup. If 2M has priority over UHF, then you will hear that signal. If UHF has priority, you'll hear UHF. If they mix, (I think the LinkComm controllers can be set that way) you'll hear both combined, which means if someone is full quieiting in to one and noisy in the other, he'll be noisy. There may also be some weird problems with propagation delays, since it will take the audio from the remote rx longer to get to the controller, and mixing the two could give a slight echo effeect. Maybe. In other words, make sure one has priority over the other! -- Jim Barbour WD8CHL Yahoo!

Re: [Repeater-Builder] Desense Problems
How does the repeater act into a dummy load or service monitor?? something that u know how a good or proper 50ohm load.. Brent - Original Message - From: Scott [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Cc: Scott [EMAIL PROTECTED] Sent: Friday, December 10, 2004 12:51 PM Subject: [Repeater-Builder] Desense Problems Hi AllI've got an installation here where I have three 2 meter antennas and a 2 meter repeater that will only operate on one of them without serious desense. The antennas are a simple J pole, a Hustler G7 ---144 and a small triband vertical. I know that none of these have much to offer and I am now in the market for a proper commercial repeater antenna but just the same, what is my problem?-only the J pole works acceptably. VSWR on all antennas using the repeater signal reads unity or very close to it between duplexer and antenna feed line, distant transmitt signal strength measurement sees the Hustler a bit stronger and they all receive a distant weak signal (repeater transmitter off) about the same (maybe the Hustler is a bit better). What I'm saying here is that all three antennas seem to work about right for what they are except that I get serious desense on two of them---30 watt transmitter, a two stage isolator in place, 6 can P-D duplexer and about 20 watts into the antennas no duplexer tuning between antenna changes.
