Greetings Forum,

I am contemplating purchasing the Motorola GR1225 UHF Repeater as my very first GMRS repeater. I want to purchase this to provide my subdivision with better quality GMRS communication abilities, while at the same time, learning about repeaters and antennas.

 

Does anyone have any current or past experience with this repeater? What is your opinion of this repeater for a beginner? Thanks in advance for your comments.

Oh, okay. That is good information. I'd hate to make a fumble with it, in my learning, only to find I couldn't fix it. Thanks.

WOW! I just learned that even though you may get a good deal on a Motorola radio or repeater, it may not be a really good deal. $300 for the software to program these things! That's at least two times more than what you can get the radios for! WOW! I guess ICOM has spoiled me.

 

That's a shame. I really like the Motorola product. What a lesson.

A radio shop won't charge a fortune to program it for you.

From personal experience in my primary area, once a piece of Motorola equipment no longer has factory support, the local dealers will not even do programming.  Sounds like Motorola is taking a lesson from Microsoft with planned obsolescence to sell new products where profits are substantial, while thumbing their nose at customers who won't play their games.  :angry:    The local Kenwood dealer's business expands every year because they add old Motorola customers to their client list.

when I bought my Kenwoods my boss asked why not Motorola's, simple answer is they don't do what I need them to do.

I agree, they have played that game forever. Everyone's mileage will vary, usually you can find a shop that will still do them, since the shops are not owned by M. If not, there is always some good ol' boy that has a copy of the s/w he downloaded from a foreign website. LOL.

Former GMRS WQGK720,Ham W2ERD. My GMRS repeater was and still is a Motorola Desktrac UHF, the nice thing about these repeaters is that they have thier own power supply and fan and in my case it run 24/7. They can be purchased off Ebay for about $350 to $500  and if you know a Ham operator he may have the software to program it . You can use a mobile duplexer which you can be purchase from China for about $50 or less , they even will tune it to your, or you can us two UHF antennas  one TX and the other for RX. With any radio system you need a good UHF antenna,and a short run of LMR-400 coax with N-connectors if possible and you need to get in up high. My system when it was on line would cover about 25 or more miles at 28 watts . When it come time to renew my GMRS licenses it would have cost me $200 and because my repeater got very little use I let go.

 

Because of the narrow banding a lot of good Motorola radios are up for sale. I have four 900Mhz repeaters running 24/7 now all using Motorola radios.

 

If you need programming and are willing tp pay the postage both ways I can help you.

If any one is looking for a good cheap GMRS HT check out the Baofeng Dual Frequency UV-5R on ebay for about $60, it will cover all the GMRS frequencies as well as the 5 MURS VHF open to the public.... I have 3 of them and they are outstanding buys for that money...and they program easy...

I stand corrected on the fee to renew the GMRS license, $85 for five years.. Back to the Baofeng UV-5R HT it also makes a great scanner..and it also receives FM radio....

I've got two gr1225's in service.  the only problem ive ever had was a cold solder connection.  All of them do it a one time in their life.  it didnt cost much to fix, and the shop charged me 85 for programming and tuning diplexer.  The shop i use has a lot of these inservice as community repeaters.  mine work great, keep it around 25-33 watts.

I have one of these in service now and I love it. From what I understand the low power setting is 25 watts and the high is 45 watts. If I wanted to dial the high down to 33 watts as mentioned in the previous post, that can be done through the RSS correct? I'm assuming I'll also need a watt meter for this as well. I might even only dial it down to 40 watts high since the repeater is not very active.

if you want the PA deck to last a long time keep it at 25 watts at this power level the repeater is 100% duty cycle at 45 watts it only 50% duty cycle we have one that had a bad PA and I put a 10 watt gm300 PA deck on it set it to 6 watts and put a 10 db Attenuator on it now has a 1/4 watt out driving a msr2000 PA set to 50 watts and it dont get hot only warm plus we have 2 cooliing fans on the PA deck the best thing to do with a 1225 repeater is set it to 10 watts and get a TPL amp that takes 10 watts to drive it and you'll never have to worry about the PA deck by the way I got the 1225 with bad PA for $5.00 one hell of a buy

this is the same way I run my 650.

have a Kenwood TKR850 running 3W into a Johnson 1010 PA that can do 110w/15in. the amp was rated 100% duty cycle at 100W and could be pushed to 125, never went beyond that though. as a side note if tuned properly will only pull 17A of current.

this set up will run all day & night as long as the power supply keeps up.
