Hi,

 

I have programed a Motorola Radius GR500 (40 Watt), and am getting ready to run some back yard tests before I put it up on the hill. I'll be using a hand built ground plane antenna on top of a pretty high point (not the highest) in town, should give good coverage, just wondering if there are any tips that anyone has before I go live with this thing.  

 

RX 467.550, and TX 462.550, a PL code will be set, and given out when I figure out what exact one I want to use. This will be a club/emergency repeater.

From previous experience, don't publish the CTCSS or DCS codes here at MyGMRS or locally in your area.  It may be wise to split the input and output tones or codes to help keep unauthorized users from getting in.  I always ued to use a DCS to activate my systems and a CTCSS on the output side. This isn't foolproof because some scanners as well as some radios have the capability to determine DCS or CTCSS - however, unless they are physically near a base station or mobile while that is transmitting into your repeater, they will not be able to catch the repeater input code.

 

Good luck with the system.

Thank you!

 

I wasn't planning on posting the codes as I'd like it to be for club use only at this time, and the area is small enough that I don't think there'll be any trouble with the tone in and out being the same--but I think that we may wind up using separate tones in order to buffer out the riff-raff.

 

With any luck, I'll have this up and running within a couple weeks :)

Please keep in mind that as a "club" repeater, each user or user-family must be licensed individually.

 

You can refer to 47CFR95.3 >

§95.3   License required.

Before any station transmits on any channel authorized in the GMRS from any point (a geographical location) within or over the territorial limits of any area where radio services are regulated by the FCC, the responsible party must obtain a license (a written authorization from the FCC for a GMRS system).

Thank you :) I've got a Facebook page that I'm editing, and I'll post that information. Also looking at a website as well :) All the folks that I know that will be using this system are licensed properly.

 

I appreciate the page you guys run!

 

TTFN :)

CCR's aren't capable of some of the more prevailing signaling methods…

This is why I decided to not list tones, instead a person can contact us via myGMRS or part of the local GMRS community that have repeaters up in the area.

 

I am seriously toying with doing MDC1200 as the way to access the repeater if it ever becomes a problem, or just go Part 90, I have a Non-profit I own/run that would qualify if need be.

Apologies for my limited knowledge on this, What is a CCR?

I have a for profit that qualifies me. (Zapped Communications)

CCRs are cheap Chinese radios.

LOL! CCR... That makes sense, and pretty funny. I have a yaesu rig in my truck, and the hand helds are the Baofeng uv-5r.

I will be setting a RX tone for the repeated, and probably a different pl for the TX of the repeater as mentioned above. I've also toyed with the repeater TXing in the clear with a pl for RX... Probably do that with the next repeater install that I have planned... I've just have to secure another site on top of the mountains to the east now.

My future plans for the area include remote areas for hunters, hikers, and other recreational stuff. Just need funding to get things set up.

There's no GMRS radio provider in the area at all, so for me, starting a for-profit club is not an issue.

Makes sense. I though about "talking" my way onto the tower Custer County SO uses for a QRP repeater. Site has LOS to Monarch pass, Pikes Peak, most of the Wet Mountain valley, Pueblo, the Springs, and possibly Walsenburg. Think I had a design for it at one point that only required a 7W setup on a DB413.

Repeater is going to its final home this weekend! I'm building a more robust antenna tomorrow, tuning it, and then enclosing it in PVC. The rig will go on a 15' poll that will be on a 20' tower ~550' above the city on the south side ov the Valley. Just have to get the output PL tone set fully, and the install will be complete.

The repeater didn't make it fully up, went online for a bit, then had some issues with the power in the shack. I'll update when it's online again :)

One of the Grand Junction Area Repeaters is online :) It's only 38' off of the ground, but will serve the area it's in really well. 

 

I have two or three more repeaters planned for the area, Just need to gain interest in the area for more users.

Update: I'm moving the repeater to Black Ridge tomorrow. This should provide a lot more coverage for the area as the radio will be 2,847 feet above the average terrain.

 

I'll keep this thread updated.

After having the repeater on Black Ridge for a couple days, we realized that we needed a Notch Filter in order to communicate further than 5 miles from the repeater location. All the Broadcast equipment on the site was numbing the receiver really bad. So today I was able to get the repeater 100' above the average terrain, and it is now online and running.

So the repeater was moved off the mountain? The antenna is at 100' AGL now? That will give about 15 miles LOS average.

It's up higher, I put the wrong calculation in.... It's more like 250 AAT. Still testing distance, but it's shooting way over 15 miles. I'm able to hit Mile Marker 64 on I-70 from its location on the map. The repeater is WCG1.

Will follow up with real world test results in the coming weeks.
