Went with the 213 no foil. Got our newer set of radios cdm 750's and an ID-O-MATIC voice version installed. Now just have to get the new feedline installed and the antenna mast higher. Thanks everyone for your input. She's coming along!

My repeater is programmed to ID via every 15 minutes via Morse code and it does so without the PL tone. Mainly just to ensure it's still working without having to key it up. But you are correct there is no requirement for the repeater to identify as long as each individual user does.

If that LMR-400 cable is brand-new, it will work great for about a year, then it will start playing havoc with your receive signal.  The foil and the braid will start to oxidize in some areas, and loosen-up in other areas of the cable, causing white noise to be generated by the feedline itself by the transmitted signal.  You will then experience terrible de-sense in your receiver due to the white noise.
 
LMR-400 is great for two-way communications, but only one way at a time.  When you are using a coaxial cable in a repeater installation, where it has to send a transmit signal, and still receive at the same time... that's where you run into trouble with LMR series cables, or any other brand of foil-plus-braid cables.
 
RG-213 with full-braid shield and no foil overlay would be better for this application.  The BEST solution for a 50 or 75 foot run would be 1/2" Heliax.  For longer runs at UHF frequencies, I'd go with 7/8" Heliax or larger for best results.

As for IDs, Ham station operators and repeaters are required to ID at the beginning of a contact, then end of the contact, and every 10 minutes during an ongoing contact.  For GMRS users, it is the same, only 15 minute intervals.  GMRS repeaters MAY send an ID using voice or modulated Morse code, (not CW), but are not required to ID at all.  However, GMRS USERS must ID themselves using the 15 minute rule, whether using a repeater or not.
 
That's my interpretation of the rules, and I have read them all very carefully.

This link gives a side by side comparison and seems to be fairly accurate, based upon other such sites that I have seen in the past.
 
For temporary runs, our Chaplain Responder equipment trailer contains a 75 foot section of Belden 8267 (RG-213). Never had any issues with it on our licensed VHF frequencies or GMRS.

John, thanks. I got it up and she gets a usable max of about a 10 mile radius. It's full quieting in many areas within our city limits.  I do have it ID at 20 min intervals. Your comment put me at ease and encouraged me to get it up there. I'm even more encouraged to invest into a better system down the road. This system allows me to get my feet wet.

What do you have for antenna height? Obstructions? In most applications the height of antenna is most important. using a ground plane I assume a Mag mount? Although not ideal, it could get you started. Tell us more about your site.

no ID is necessary. my machines ID system name not my call once an hour.
just put it up no approval needed unless you exceed certain height limits near an airport.
are you going into a site or at your house?
