Re: [Repeater-Builder] Want to add VHF cross band link for my portable UHF repeater
At 08:42 PM 05/30/07, you wrote: I have a portable UHF repeater being put together and I'd like to include either a simplex or duplex VHF system to link in/out to existing VHF repeaters or VHF simplex users. The UHF side would be the local master repeater with the duplexer. I have that already. I have not picked a controller yet. What would work well on this and also draw as little current at 12vdc as possible? DTMF control would be fine. Thanks! Ronny K4RJJ Any of the two port (or more) controllers should do that. The Scom 7K (two ports plus a control receiver), the ICS Linker II, any of the several NHRC ones, some of the Link RLC line, and more. Most have a command that shuts off the front panel LEDs to conserve current. In your shoes I'd wait a few months - Scom just announced their three-port controller (the 7330) as being in beta test and I think that as soon as it's available for ordering/purchase there will be some 7Ks available ... If you can't wait, I'd look at the NHRC comparison matrix at http://www.nhrc.net/comparison.php and take a close look at the NHRC 4 and 5. The 4 is available as a $40 partial kit. However it does not offer much in the way of remote control of a remote base radio. On the other hand, Arcom has a 3-port controller kit (the RC210) that DOES have the ability to control a frequency agile remote base radio. On the other end of the cost spectrum a local ham has an NHRC-10 on a UHF repeater controlling a Icom 706 HF/VHF radio giving him a frequency agile remote base that covers 160m through 2m. It's located at an FM broadcast station site and he uses several sets of the tower guy wires as inverted V antennas... the higher the guy wire level on the tower the longer the guy wires...

Re: [Repeater-Builder] Do Anyone Use Their Repeater For This
We do that on our VHF and UHF systems- We have a two-tone page sequence in a macro and users with moto, kenwood, etc radios, and I suppose if you had a pager, can program the QuickCall into their radios. We use it for alerting when skywarn activity takes place. I leave a GP-300 on the counter at home set to a channel with that programmed so the wife does not have to listen to regular chitter-chatter, but when we start spotting activities the tone sequence makes the radio beep and opens up the reciever for her to hear what's going on. When it's over she pushes the little gray button and it resets the radio back to standby until the next page. I would assume the right pager can be programmed that way too. We use S-com 7K controllers and its simple to set up- pick two frequencies and durations and program away!

Re: [Repeater-Builder] Do Anyone Use Their Repeater For This
Hi Chris, We are interested in having such a setup, but need to know if anyone else is doing it? If so, how are you sending the tones for the pager and such. (A disclosure: My company used to make the 7K controller that several folks mentioned in their responses. Its replacement, the 7330, also supports tone paging.) Generating paging tones is usually the job of the repeater controller. Not all controllers do it, and many folks don't care. Tone paging isn't all that popular any more, having first been replaced by digital paging and then by cell phones. The controller needs to increase the tone amplitude when paging. If the controller has only one tone level pot, you'll probably want to set it so the CW identifications and courtesy beeps loud enough to be understood but low enough to not override a conversation. On the other hand, a paging tone needs to be fairly loud (about 3.3 kHz of deviation) because the paging receiver is expecting that level. The tones also need to be fairly free of distortion and close to the format's specifications. That includes the accuracy of the tone frequencies and the durations of the tones and gaps. And, it's handy to be able to pre-store the pages in memory so it's easy to call them up with a DTMF sequence. Hope that helps - 73, Bob, WA9FBO S-COM, LLC PO Box 1546 LaPorte, CO 80535-1546 970-416-6505 voice 970-419-3222 fax www.scomcontrollers.com AOL now offers free email to everyone.

A pass freq plus a reject freq indicates the unit is doing both pass and notch. Still fine for one half of a duplexer. Well, it IS a notch only duplexer no matter how you look at it. Don't get hung up on a silly sticker. The thing has been retuned, simply, so the sticker does not apply to the tuning. I know quite well what a duplexer is, and it is certainly not a requirement to label both frequencies on every label. Often you find a label on each port (transmit and receive) with the respective pass (or notch) or both frequencies. As you can see by the cavities, there is only one port in use. One connection, with a coupling loop, and a coax T is a NOTCH. If ANY of the cans were bandpass, there would be TWO connections (coupling loops) and the coax would go in to one port and out the other. Please keep in mind that one can build a 'duplexer' out of 'cavities' and those cavities can be 'pass' or 'notch' or 'bandpass/bandreject'.

Does anyone know of a software program that will take discriminator audio and display the DCS (or, optionally, CTCSS) being used? If not, can someone point me to the technical specification for DCS?

Re: [Repeater-Builder] DCS decoder software?
There's some info on DPL/DCS on Mike Blenderman's web site. The code is basically 23 bits, 9 of which are the 3-digit octal DPL code, 3 bits are always the value 100, and the rest are parity/check bits to insure against false decoding. It is usually sent as frequency-shift-keying of the carrier, with the same amount of deviation as PL would be. That's about all I remember. More to read on the web if you look for it.

[Repeater-Builder] Duplexer tuning - sanity check
I'm tuning up a cavity-type duplexer for a 70cm repeater, and in the process, I showed my results to a fellow ham. He asked a couple questions that cause me to think; so I decided to ask the experts... FIRST QUESTION TOPIC: For reference, my primary cavities were made by Tx-Rx Systems, and have both bandpass and band-reject tuning controls on each cavity. When tuning them (either singularly or as pairs in-series), I see and can adjust the band-pass and notch for the desired Tx and Rx frequencies. However, in the broad-band sweep, I can also see a bunch of other signals passing through the cavities; all of which are well away from my Tx/Rx frequencies. I suspect that these are normal, and are a side effect of how the can-type resonant cavities work. Am I correct in this assumption? As a sanity check, I combined this set of cavities with another (Phelps-Dodge) set I have, and tuned these supplemental cavities for band-pass only (one cavity for my Tx frequency, and one cavity for my Rx frequency). Sure enough when I put these in series with my primary set, I can eliminate nearly all of the other signals from the broad-band sweep. This observation seems to reinforce my initial assumption about the Tx-Rx cavities. Do you agree? SECOND QUESTION TOPIC: The other ham thought that I should end up with a band-pass that is narrow enough to eliminate adjacent repeaters (at 16kHz spacing, as per the current SCRRBA band-plan separation). I tried but I cannot get either set of cavities to have that narrow of a band-pass; at least not without sacraficing most of the signal in the process. I suspect that the receiver and transmitter need to actually inforce these much narrower bandwidth requirements within the broader protection provided by the cavity-duplexer. I suspect that I should focus my duplexer tuning on passing the desired frequency, notching the alternate repeater frequency, and trying to do so with the least amount of signal attenuation. Am I correct in these understandings? For both of these question topics, feel free to point out anything that I might be missing or misunderstanding. I'm by no means sensative about this stuff, and still consider myself on the learning curve about duplexers and repeaters in general. Thank-you (in advance) for your time, thought, and opinions. vern

Re: [Repeater-Builder] Duplexer tuning - sanity check
Some duplexers pass the desired frequency, lose something on each side, but then pass stuff from DC to over 1GHz as if it's not even in the circuit. My Celwave 526 operates that way. The bandpass tuning is rather broad and serves to match the impedance more than effect the bandpass of the signal. The notch tuning is very deep (40dB per section). It will keep the transmit signal out of the receiver very nicely. If you take an isolated bandpass can and sweep it, you'll probably see low loss at one frequency and high loss everywhere else. Duplexers don't always respond this way. Your mileage will vary depending on the design. The duplexers on UHF are typically set for 5 MHz spacing, although closer spacing is often available. The purpose of the duplexer is to allow the receiver and transmitter to share one antenna. They offer very little filtering of other nearby signals. You need a good, selective receiver front end to handle that. The transmitter can often be cleaned up by adding an isolator to the output; some units may already have that feature, especially commercial base stations. You always tune your duplexer to your two frequencies; other nearby repeaters are not a concern when tuning the duplexer. It's just there to allow your TX and RX signals to share the coax/antenna. If you have nearby stations that you need to filter out, you must add your own very narrow filters external to the duplexer. Usually these will be notch filters or even shorted stubs. A bandpass filter is rarely narrow enough to reduce interference from signals less than several hundred kiloHertz away. It will have no effect on the signals from a repeater 16kHz away. The tuning of the duplexer just isn't that tight, and in fact even the best duplexer will allow a lot more leeway in the TX and RX frequencies without requiring retuning.

RE: [Repeater-Builder] Duplexer tuning - sanity check
To add to what Bob said; Band pass/reject type duplexers are basically notch type duplexers with the loop tuned to form a little bit of band pass effect. The cavity itself tunes the notch and the tuned loop forms the pass band part. Most of the pass band rejection will fall between the two frequencies of the duplexer. Part of the pass band rejection comes from the wide skirt of the notch of each set of cavities i.e. the overlap of the high and low notch skirts. Above and below those frequencies there is little rejection, sometimes only 10 or 15 db. Think of the pass band above or below the notch frequencies as what you would get by using a tuned coax stub for a pass band filter, it will be pretty broad. On UHF with 5 MHz spacing you can make a duplexer using all pass cavities, although it will take more cavities than using notch cavities, but it will give you a superb duplexer with a nice narrow receive window and you will get very little response above and below the duplex frequencies. Pass cavities do have some spurious responses out away from their pass frequency but they are usually pretty far down. A pass cavity duplexer will have a little more insertion loss than a notch type duplexer too. You can learn a lot about how much rejection and how wide a pass or notch really is by looking at the curves of cavities or duplexers on the web sites of the various manufacturers. Look at the frequency verses loss and you will see just how much, or how little, the rejection is as you move away from the tuned frequency. With a pass cavity they will usually show the curve with 3 different insertion losses set so you can see the difference. Some will also show the result of 2 and 3 cavities in series. 73 Gary K4FMX -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:Repeater- [EMAIL PROTECTED] On Behalf Of Bob M.

It decodes PL, DPL, DTMF, from the discr. and stores the 'hits' for later printing. I use it most every day for trouble shooting interference, ect. It can also generate the PL, DTMF and DPL codes. ..

An enhancement to the DPL / tone PL display function would be a storage feature so I could park it and a receiver (i.e. a 18ah gell cell, a Maxtrac or a scanner, an antenna and this box) on a hilltop and a week later it would tell me what tones/codes are in use on a particular channel.

Re: [Repeater-Builder] slightly OT: securing feedline to the side of a tower
Jay, My local tower guy told me 5 foot max between supports. If the coax moves in big winds, it'll make noise. I'd avoid the EMT clamps. Use real coax stainless clamps. the EMT clamps hold the coax against the 2 rails of the uni-strut. Those 2 edges are a little sharp if you get the clamps too tight and will distort the feedline. Gerald Pelnar WD0FYF McPherson, Ks Hi Folks, This weekend I will be un jury rigging a lame feed line install at my repeater site. The tower is a 300' four sided guyed monster. I am planning on using uni-strut on the side facing the building and using butterfly clamps or EMT clamps to hold my feed line. I am open to suggestions on the vertical spacing of my unistrut brackets. At what interval should 1/2 - 7/8 and 1-1/4 heliax be secured? Any suggestions? -- Jay Urish W5GM ARRL Life Member Denton County ARRL VEC N5ERS VP/Trustee Monitoring 444.850 PL-88.5
