NEW TO REPEATER BUILDING
My name is Jonathan (KE4UTT) and along with Mike (KE4WIN), we are going to be
building a UHF Ham Repeater. We have a wonderful site that will put us up about 700 feet on a broadcast tower. My Question(s) are as follows: 1. What type of radios does anyone suggest using (i'd like to use a high power radio, ie something with 100watts out, if possible)? 2. What type of controller will allow me to have decode of PL tone as well as an autopatch and multiple users..etc..? 3. How do I go about hooking them all together and getting them to work. (I've never really done a project like this before) 4. What does "COR" mean? I've seen it in different articles and am unsure what it stands for/what it does... 5. Would I be better off building an antenna? or buy one. I'd like to get something with the MOST Gain possible (seeing as I will loose quite a bit with the long run of Coax. (can't aford Hardline). Thanks for everyone's time in advance..and from "watching" the list for a while you all are very intresting and very helpfull. I look forward to learning everything I can from everyone.

Dayton etc.
Richard D. Reese
Well I am finally home after two and one half
weeks. Went to Dayton then Vegas, California, Oregon, then Washington. (Thanks to the 146.88 Green Mtn machine) I have 26 rolls of film to process. Will post some of the pictures to the site soon. (Fred, I received the pictures you took at Dayton. Thanks) Have lots of mail to go through. Those of you that sent messages requesting information etc. please be patient, I will get back with you soon. If it is urgent, please resend it and mark it priority. I have several hundred messages to sort through. Thanks in advance. -- Richard D. Reese WA8DBW |

Re: Link Controller @ Vertex Repeater
"" ""
Hello all,
Jeff here, Just bought a UHF VERTEX 5000 from yaesu. I have the RC1000V controller to interface with. Have any one done this kind of setup before. Any heads up of how to interface the controller to the VERTEX unit will me much appreciated. 73, _______________________________________________________________ Get Free Email and Do More On The Web.

Advanced Receiver Research makes the absolute best receiver pre-amps knownand easy to repair...I have repaired several after a bout with lightning...yeah the rptr and ps got it too. I have seen one incident where rf blowed the gas ass fet(ha)..not enough isolation between tx and rx.....thats the only non lightning failure I have had experience with. Ed |

Re: Digital Audio Delays

where it is inserted at the exciter and activate the relay with COS thereforethe time as a back up.I have something similar here except a little more versatile...If the main port is in Monitor to port 2 or 3, OR if they are connected (transceive) the tone is continouslly transmitted....drop the main rptr courtesy tone too since the other system courtesy tone is what you need to hear. IF the autopatch is accessed, the tone is on..no courtesy tone..the inital id is encoded so the time / temp / wind speed at the rptr shack is heard..the signal quality test and all voice mail (both private and public) are encoded so they will be heard. I found that about .6 to .8 seconds is the best hang time for the encoder output and at that same exact time the courtesy tone is sent (has to be short !) the dtmf decoder mute timers are set at .8 seconds (enough for anyone unless you got riggamortis). And the digital audio delay is at 100 milliseconds.I also modified the "hang time" on the ts32 enc/dec bd so that the controller will see a shorter "on pl" time, it worked out to be about 300 milliseconds...so I tried to make sure there was a minimum of "falsing" on the cor/dec. The controller is RLC 2 a by Link Comm. Ed |

Let's see.... you attach -12v to the ground pin, +12v to the voltage in feed through. I used a separate 2.5 Amp regulated power supply. Ah, tell me if I'm wrong, but isn't the current flow dictated more by what's IN the box than what's outside it? If a 100W light bulb pulls 25 amps, do I blame to power company for giving me too much current? By the way, this was a RX only voting receiver site. No other transmitters at this site, so I was pretty sure I wasn't blowing it with RF. I may have just caught them on a bad couple of months.

I have take another approach I inserted a reed relay in the CTCSS line where

it is inserted at the exciter and activate the relay with COS therefore CTCSS is only transmitted when there is COS. This is only a problem with marginal signals. You never hear IDs or even the courtesy tone, no squelch tail only users talking. I am now designing a small delay to keep the CTCSS up for about .1 second to help marginal signals. I like it. I also put a second relay across the first to defeat the first and transmit CTCSS all the time as a back up. __ Paul L.

I've used several of their pre amps, some ham and some commercialAdvanced Receiver Research (ARR) preamps the best you can get forI know every other ham in the world loves them, but I don't. I purchased applications. I've had the usual lightning problems that happen, no other failures. If your frying the inductor, you have to be putting some serious current thru the thing. I've never had this problem, nor can imagine what can cause that situation. Maybe a current loop thru your equipment? Are you using a piece of commercial equipment that has an isolated ground, and your pulling the current for the radio thru the preamp? I like to fuse everything with an appropriate size fuse. Their tech support really had a feeling of a small operation.Yup, you are correct. I have stopped at their operation here in Connecticut several times, and it is small. But, I still think you get a quality product for a good price. Some of the help seems to be part time. This time when I sent it back, they said they never got it. They won. IThey have done about 8 preamps for me, some were repairs and others were frequency change modifications (75Mhz units to 52Mhz units). All came back OK and the repair price was very reasonable. They have an interesting assembly process. An 8.5x11" binder contains drawings and parts lists for each model of the preamps they sell. The assemblers turn to the page and stuff the parts on the board and solder it up. The tech then tests and aligns the preamps. 73, Joe, K1ike |

I would say Angle Linear Preamps is the beat. Been running them for years on
both VHF and UHF. Chip Angle's preamps are very respected in the business. Randy AH6GR HQ54@... wrote: From: HQ54@...-- See Randy's ("The Guru") Personal Homepage at |

I'm using S*COM boards on several controller brands (ACC, CAT, Hamtronics, and soon CSI) and have had great success with them. The Micor squelch is great, but still leaves the squelch click, does not get rid of touch-tone blips, and costs more than the delay board. One application note - if you want to remove the touch-tones completely, insert the delay after the breakout point that goes to the touch-tone decoder, or run a line to the decoder and cut the original audio path. Try to leave in as much of the filtering as possible before the decoder. By the way, the S*COM audio delay is virtually a direct plug-in to the CAT 300DX. The pinouts are the same. I have a problem with kerchunkers (averaging dozens per hour - 24 hours a day). Now, I rarely notice the activity. The repeaters are a zillion times more pleasant to listen to. The muted squelch tails combined with the 'CTCSS tail' means I only hear 'real' conversations. I have my CTCSS set to drop about one second after the COS, so the only part I hear of the ID is one second of the initial ID (I.E. "Welcome to the"). Adding a few initial speech 'pauses' would even remove that! I have the 'CTCSS tail' to make it easy for mobile repeater users to confirm that they are hitting the repeater - hearing a one second response tail instead of the full tail and pending IDs. They can also reply faster during conversations. It words great! I hope I've given you and perhaps others some useful tips. 73, Joe, KR3P |
