[Repeater-Builder] 222 duplexers

Re: [Repeater-Builder] 222 duplexers
Bill, One of the few sources for a 222 MHz duplexer at a reasonable price is Telewave. Licensed Amateurs get 30% off the regular price, which means you can get a TPRD-2254 duplexer for about $786. I have one of these duplexers in service now, and am completely satisfied with its performance. My standard financial nonaffiliation disclaimer applies. 73, Eric Lemmon WB6FLY pmci1 wrote: Hello.

I have an equivalent 224 MHz Wacomm duplexer in excellent condition, which I'll sell for less than half the below amount. Email me direct if you're interested. skipp025 at yahoo.com Eric Lemmon [EMAIL PROTECTED] wrote: Bill, One of the few sources for a 222 MHz duplexer at a reasonable price is Telewave.

[Repeater-Builder] Re: Duplexer Configuration Question
--- In Repeater-Builder@yahoogroups.com, Bob A [EMAIL PROTECTED] wrote: Thanks Skipp and Paul for input so far- I suspected that this would be a bit marginal. However, we're only running 40 watts, and the rx selectivity seems pretty good. It's an older Motorola, and it has 4 small cavity filters at the input of the rx inside the box. Running 600 kHz split with 2 antennas now, and I can find spots for the rx antenna in which the system works OK for local communications. To Skipp's question, the old cavities have tee connectors attached direct to the ports, and they are all SO-239. With cascaded hybrid ring pass filters on the rx, and just a notch can teed into the tx side set to rx frequency, maybe it'll go. Paul, when you say capping the other port, do you mean shorting it or leaving open, or with stub or what? Capping, in this case, normally means removing the loop and put a covering over the opening. Also, to get the deepest, sharpest notch use the lowest insertion loss setting on the can. This will make a great Notch cavity. By the way, the can in this cinfiguration is a tunable open quarter wave stub. By coaxial theory, that means, what ever frequency that the stub is tuned for looks to be a short at that frequency...oh the same stub, if shorted, would appear to be open at the same frequency. And, if these old cans are single port, no shunt Ls or Cs, does this mean they will notch as-is or will they need external help? -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Paul Kelley Sent: Friday, August 12, 2005 7:28 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Duplexer Configuration Question No piston trimmer that I can see, unless it's inside the can across the loop. I was thinking of cracking one open to find out. Anyway, though, it would have to be adjustable to peak up the cavity, so why would they hide it in there? No, they wouldn't be hidden inside. Just checking. On the ring duplexer, it supposedly just inverts the notch of the can into an equally sharp bandpassby making a steep cut away from the rx frequency, it should hold off the tx to some extentright? Well, it'll keep the transmitter carrier out of the receiver, at least to a degree. But you also need to knock down the noise generated by the transmitter on the receive frequency. If this is to be a 600 kHz split system, you probably need to attenuate that noise 60 dB or so... perhaps less, probably more, depending on the particular transmitter, receiver, etc. With cavities only on the RX side you'll have no protection from the noise and a LOT of desense. As I said, I have one additional can now, with two ports in/out, so I'll throw that one in the tx lead to make a 3-can setup. If this sounds all wet, please let me in on the right answer. If you mean just inserting a pass cavity into the TX lead, it won't give you nearly enough protection from the noise on your RX freq. I'd suggest making another hybrid ring for the TX side with this cavity used as a notch cavity. Most pass cavities work fine as a notch by capping one connector and just using the other. A hybrid ring duplexer with two cavities on the RX and one on the TX just might do it, although it'll be a bit marginal on the TX side. As I understand it, you'll need to construct 3 rings, one for each cavity. Hopefully someone with real experience with the hybrid ring will jump in here and help you out! Paul, N1BUG Yahoo!

[Repeater-Builder] Re: FIxed audio and carrier detect - Midland 70-1630B
First, try and get a service manual this will go a long way twords getting you where you want to be. Look for the buffered detecter signal.

[Repeater-Builder] REPEATER INTERMOD
HELLO ALL I need a little help on a project,we have 2UhfRitron repeaters,one is2.5 watt (461.2125)and#2is about 6 watts (461.4125)and oneyeasu 25 watt 464.4625.The 2.5 watthas degraded over the years(15 year old repeater)I can not convince thesupervisor that there is a problem with the repeater (drifting slightly off freq and intermod from the co located repeaters). Anyway these are in close quarters within 3 feet of each other on the wall and the antennas are within a 25 foot radius of each other.I am planning to use 2 maxtracs, a rick box, and a cellwave flat pack (mobile duplexer) as a replacement for the ritron 2.5 watt radio to show them that the repeater needs replacement. Now with the .4125 6- watt ritronrepeater using the same pl tone 200 khzaway from whereI will place the maxtrac repeater dose anyone see any intermod, front end overload, or signal rejection problems that the maxtrac's ? thanks .bob YAHOO!

Re: [Repeater-Builder] REPEATER INTERMOD
Bob, Use different PL tones on those repeaters. A lot of problems can occur when tones are the same on co-located radios, even when they operate on different bands. Preselectors might help solve the interference problem. Been there... 73, Eric Lemmon WB6FLY [EMAIL PROTECTED] wrote: HELLO ALL I need a little help on a project, we have 2 Uhf Ritron repeaters, one is 2.5 watt (461.2125) and #2 is about 6 watts (461.4125) and one yeasu 25 watt 464.4625.

they all are licenced2 watt channels andwereoriginally15kof3e, possibly 12kof3e now with the last renewal.I dont know what the vendor did when they installed the yaesu repeaterbutI want tocheck it.

[Repeater-Builder] MASTR II Repeater NHRC 2 and TS-64 installation
Hey gang, I have a MASTR II UHF repeater (not a converted mobile or a station) We am going to use it for a Hub/Link repeater for our Linked 220 system. I have built an NHRC II controler from a kit(less than $60.00). I have the controller wired to the station, programmed and all my audio levels set and it's working just fine. I have a ComSpec TS-64DS CTCSS board. And the Made for GE MASTR II TS- 64DS MII. I need to intergrate one of these into the repeater. I need it to TX Tone only when COR is present. This is so the CW ID of the controller (Hub repeater)want go out over our 6 220 repeaters. Anyone have a neat way of wireing the TS-64 into my mix?
