What cables between the CDM1250 and the second CDM1250 and duplexer ? How long is the LMR400 ? What is the Watt meter show on the antenna side ? Where do you hear the white noise ? On the RX radio ?

If its the early CM300 its Commercial Series PPS. It can still be purchased and downloaded from motorola. You will need a programming cable in addition. If its the new CM300d then same applies but uses Trbo Software.

Most likely desence. Just because you hear the tail does not mean the signal is good enough to pass audio. Who tuned the duplexer ? You need to give us more info on the setup. Repeater Model Feedline type Antenna Type Antenna Height ?

It is done in DOS as said if its truly the X9000. It requires a special cable to the RIB. Its been many years since I did one. Which head is on it ? Most X9000 came with the W9 Head with a plug from the harness. The plug on the harness should have a Orange and Green Wire along with 2 for speaker. Some were black with a stripe and should have a molex plug on it. Alot of good info HERE

Correct. Public Safety and LMR frequencies have specific frequencies for mobile repeaters, ie: DVRS, Vehicle Repeater.

How long have you waited. The FCC imports weekly or daily but can't remember which. IF you jsut got the license its proabbly not here yet.

Most all new gear can move around without programming. The GTR800, MTR 3000 and SLR will work in the entire band with no issues.

No pics of my first. It was a 4 channel Uniden crystal radio. One of these 2 are my grab and go radios....

IF your GMRS radio is UHF only , you can only add 444.4 and 444.825

LDF4-50A is standard 1/2" Hardline LDF4-50A AVA-50 is the 7/8" Hardline. Anything over 100' I run that. To be honest all my repeaters have 7/8" and some are only 50' up the tower. AVA-50

Few other options although you get what you pay for. Klein BT Mic Otto BT Mic

Antennafarm normally ships pretty quick. Don't think anything I have ordered took longer than a week.

You need a watt meter. They are like radios. Cheap China box to a good quality box. I prefer a Bird 43 but not everyone has one. There is a huge page on this HERE Read the linked post.

All depends on design. TXRX makes some great systems for filters and combiners. As said the frequencies were close enough but just far enough apart. And one frequency was out of the GMRS section. There are many places as TXRX and Filtronics that build this stuff but its costly to do right.

Your Motorola radio is using "Talkback Scan" In programming you define how long it will sit on that channel before it goes back to scan. Public Safety uses Priority Scan. Priority Scan goes to the Selected Channel regardless of the last transmission.

I can't answer the Bridgecomm info, but can answer on other devices. 1 - If the unit is advertised 450-470 it should allow programming anyplace in that band. Some repeaters need to have TX and RX in the close area. IE 462/467 works good but 451/456 may not. All about the tuning of the box. But yes you should be able to get a 450-470 repeater and get it on 462.467 2 - Lead time - That sometimes refers to how long before they can ship it. If they show it in stock it should ship soon. If it has a longer lead time they may stock a base model with no duplexer or something and need to get that in before shipping. 3 - Dont have one so no idea. I have found the LMR (Motorola, Kenwood, Vertex, ICOM to be solid units. I thought someone on the forum had one in the past. Do a search on the site.

I did a similar design in NY. All 3 repeaters were the same output, however all three used a different input PL. I called it a poor mans voting system. There are similar systems in public safety. Actually our SAR system started the same. Same TX/RX all over the area with different input PL tones. All TX was the same PL. Really need more info as said.

In 20+ years of GMRS we never had chatter of nets. It wasn't until the ham lite crown came over to GMRS. Remember GMRS used to be a service for a family and was never used in the ways it is now. Its not a bad thing just different than why I got into GMRS and many did in the early years. Been in public safety for 20+ years and have never heard a net on any public safety system either. It may happen but in the NE you wont hear it unless you scan the ham bands. I guess I look at the linking thing as a change also to GMRS thats not always good. HAM did alot of this and I know of repeaters that are now usesless as all you hear is ragchewing all day from half way across the US. Kinda killed some repeaters for local use.

From Post here - HERE @Flameout said - "The cablelowering it and all of a sudden I could pick up the repeater. I just had lots of noise, especially compared to the mag mount Nagoya about 3' off the ground. I really wouldn't mind buying another antenna if I knew it would work. Too bad there isn't a store that rents them is 50' of ABR Industries RG 8/U and the SWR is great (but then again, it is also great using a dummy load) I had the antenna up about 20' but experimenting one day, I was" @WROZ250 gave you some good info. For a base radio I'd use the best you can find. You said you are using 50'. Do you really need that much cable ? I would use the least amount as possible. I'll be honest I would not even entertain 50' of LMR myself but know not everyone can afford LDF cable. I would say if you can get down to 25' of cable you may find a much better experience. I will also suggest watching ebay for LDF. I have seen 50' chunks for around $100. You need to search and it may take some time but LDF is online and can be had reasonable.

Guys lets move this to another thread ? Think its a good discussion.

The ICOM 4008 base was the design of the soldier inter-comm for the US Army. We sold many of those when I was at a ICOM shop.

Nope. Sorry Im not a fan of nets. They should be on Ham radio in my opinion. A national net just ties up repeaters when no one is listening to them.

What are you using for Cable ? Although I consider the comet/tram a hobby antenna you should be able to hear the repeater unless the repeater isn't a quality unit, or something crazy wrong with your setup. The Laird 4603 is a solid antenna. But I'd be curious to know why yours is not working.
