Re: [Repeater-Builder] Re: W1GAN and square duplexers aka homebrew duplexer
As I recall, an early ARRL VHF manual had a brief chapter on repeaters, and I believe there were two articles that were of interest. One was the duplexer and another was a four bay folded dipole antenna for repeater use. If you know where the four vertical bay antenna article is located, you may find the duplexer article also. I think it also was a QST article. I remember one fellow who built the duplexer complained that when it was hit by lightning, it disassembled itself. He had made the outside tube out of individual sheets of copper soldered together, and the solder joints let go when it took the strike. 73 - Jim W5ZIT --- On Tue, 4/28/09, cruizzer77 atlant...@gmx.ch wrote: From: cruizzer77 atlant...@gmx.ch Subject: [Repeater-Builder] Re: W1GAN and square duplexers aka homebrew duplexer To: Repeater-Builder@yahoogroups.com Date: Tuesday, April 28, 2009, 5:18 AM It's interesting to hear about your projects!

[Repeater-Builder] Linking and interference problem
I was hoping you can help our club with a repeater link problem. What we have are all GE master 2 stuff. Here is what we have going on. we have had for years a 147.270 + repeater that works great. Last year we added a link into a central state repeater system using a link radio on one of our ports. It transmits on 442.025 and receives on 443.2. For six months we have used the link fine without problems. Last week we installed on another port a uhf repeater to be used as a hub for the north central part of our state to also link to us and the central state system. The UHF Repeater receives on 449.750 and transmits on 444.750. We can link the 270 to either the link to central state or the UHF repeater hub with no problems, but when we link the 270 to both or just link the UHF repeater to the link radio, once the UHF repeater is keyed up, the input on the link radio is hearing it so we have an awful squeal and intermod back into the 270. There is also a pager at the location that I can hear when this happens but not any other time. Again they work fine as long as both UHF machines are not in use at the same time. When the 270 is linked into Central state, even if the UHF repeater is not linked in, if you key the UHF repeater you here the squeal on the 270. I can see how as the link input goes out over the 270 when they are linked. I am not sure why I can also here it on the UHF repeater when I unkey it, even if it isn't linked in. Other than the last part of that it would make since to ne that I have the two 440 antennas to close. We have them about 10 feet apart, but the one can't go higher and the other can't go lower and still serve the purpose needed. I am thinking I need some kind of filter, that I can put on the link radio, that will protect it from the transmit of the UHF repeater. In other words the 444.750 is coming in my receive on the 443.2. Changing freq is not an option due to several reasons. If I had a filter of some sort, that would either allow say 442-443.5 to pass and attenuate everything else that would be great. Or something that would pass 442-443.5 and attenuate everything above 443.5, then that would work. Guys, what am I looking for and where might I find it. Must I build something that is this custom, or can I buy it. If I must build it, where should I start. If I can buy it,, where from and what would they call it. If my thoughts are off base, please help me to know what other questions I need to answer to solve such a problem as this. I thought maybe the pager was just interfering, but why would the 270 work fine when linked to the link radio, or linked to the UHF repeater, and the only time we have the problem is when the 270 is linked to the link radio and the UHF repeater is keyed up, regardless of whether the UHF repeater is linked in or not. I know my question is long, but m hope was to explain the problem with enough detail that you might have an answer for me. Your help would be greatly appreciated by our Club. 73 de John Godfrey KE5NZY BARC Pres. DISTRICT B ADEC ASTEN NM
[Repeater-Builder] Astron Rack Power Supplies or Motorola for new project
Hi everyone, I just picked up a MSR2000 and MSF5000 recently. I'm wondering what the group thinks about using an Astron PS in place of the Moto back-breaker (sorry, mine still hurts) that came with these units? I've never seen a Moto fail, but for consolidating these two into a taller cabinet, would it make sense? I know it depends on the current consumption, but for a 40W station and a remote receiver application I'd hate to add 80lbs or more. What about how old is too old for a Moto PS (specifically the MSR2K unit)? Thanks, Tony

I have several lengths that are in very good shape that were donated to a repeater group that I am part of including a couple of 300 footers and need a ballpark value as we can't use all of it---some local hams are showing interest.

Re: [Repeater-Builder] Astron Rack Power Supplies or Motorola for new project
Tony, I am not sure about the MSF-5000 but the MSR-2000 requires well filtered and regulated 9 and 12 volt supplies for the RF deck and control shelf while the PA has its own high current 14 volt supply. Some MSF-5000 models require 24-28 volts for the PA depending on power output. You would be hard pressed to fulfill the various supply voltages with the Astron. The cabinet and frame of both stations are similar and are designed for stacking through the use of the two auxiliary bolts that fasten the bottom plate of one cabinet to the top plate of the other.

Bill, Obviously the place to start is the appropriate section of the Rules which apply to the service where you are licensed .

Re: [Repeater-Builder] Rule Question
Control stations are designated as FX1 for the station class on the FCC license. Under the 6.1 meter rule their location may also be designated as operating XX kilometers around a specific geographic location or county wide or state wide etc. Antennas mounted higher than 6.1 meters require specific geographic coordinates for the location of each station.
