[Repeater-Builder] Re: GE MVS VHF Repeater?

2007-04-27 Thread jstechnicalservice
I have been using a MVS repeater in a commercial setting for several years and to date have had no problems. I'm using it consistantly at about 40% duty cycle. It does require 2 radios which are easily connected to each other. --- In Repeater-Builder@yahoogroups.com, "dakaratcaptiveree

I believe the program you are speaking of is called Comm Shop. I'm pretty sure I still have that if you want it. Jeff S.

When you read the unit, it changes nothing. It will ask you if you want to communicate with the unit to read but unless you make a change in the program, it will stay the same. No jumpers to change ever once the unit is set up and installed.

[Repeater-Builder] Best coax for short jumpers in repeater cabinet?

2008-05-08 Thread jstechnicalservice
I was hoping to get some opinions on the best coax to make jumpers for internal connections on a 152 Mhz public safety repeater. I'm currently using LMR400 and we can hit the repeater consistantly with a 5 watt handheld at 14 miles. The problem is we sometimes need around 15 to 16. I was hoping

[Repeater-Builder] Scanner as repeater receiver?

2008-08-12 Thread jstechnicalservice
Has anyone used a good quality scanner as a receiver for a repeater and if so, how well did it work? I'm contemplating a Radio Shack PRO-2055 as it seems to have good receive capability and picks up signal better than some of our mobile radios. Jeff Skaggs Concord-Greene FD

If it would be of any help, I have a low split maratrac that I would sell for $50 plus shipping. It was retired from one of our fire trucks and we no longer use low band, all done on 800mhz now-a-days. If you want any more info on it, let me know. I was going to list it on ebay. Jeff Skaggs Con

[Repeater-Builder] Maratrac CTCSS injection point

2009-03-20 Thread jstechnicalservice
Can someone tell me where I would need to inject the subtone from a tone panel to the modulator of a maratrac. I'm attempting to build a backup repeater for our dept and have all the connections figured out except that one. I'm not planning to use a control head just the radio itself for transmi
