The FCC does make non-itinerant frequencies nationwide, looking through the advanced license search I came across this license that has multiple non-itinerant frequencies for nationwide use.

Quick and easy question that I can't seem to find the answer to...

I know that the CDM1550 can decode MDC1200, is it possible for it to decode DTMF on a system that uses DTMF ANI and display it on the screen as well?

I'm considering setting one up to do that so I can listen to my company and see ...

601

This is the mic you would need for a GM300. The black ones meant for a CDM will work ust as a mic, but as stated, will not create DTMF tones

601

Depends on terrain as to whether VHF or UHF would perform better in your application. That being said GMRS might be the only choice of the two you mention as VHF repeater pairs are seldom granted to Business applicants. The Grandfathering of the business use of GMRS channels never expires ?

Not really a hassle if you're experimenting and learning. Just saying... That's how I know what I know today, by trial and error and teaching myself.

While I myself don't know how to, these are excellent radios. I have a few that I still use. Good luck with it!

601

Yeah, I kinda didn't want to blow anything up lol. I need to read up on duplexers and how they work and tuning...etc.... Last thing I'd want to happen. But hey, we all learn from our mistakes... especially the expensive ones like that!

601

That's what I thought, but wasn't 100% sure. Thank you so much!

It is labeled at TX and RX... that's where the confusion came in.

601

I had someone ask me a question today about a duplexer and I after a lot of research, I came up with nothing, maybe my terminology is off?

I have someone who purchased a VHF duplexer on ebay. The repeater they intend on attatching the duplexer to is on 151rx and 158tx requencies. They, however ...

601

Browsing on ebay I came across this radio, I bid on it, just for the sheer curiosity of seeing what it is, does anyone know anything about this? Is it a special model of the HT90 series? I've never seen or heard of it before.

601

I'd agree with the post above, all my SP50's do the same thing with a dying battery... Sounds like your issue.

601

I still maintain a few P50's on that frequency, if you're willing to part with it, I would take it off your hands. I personally like these radios, not worth fixing when they break though. Definitely a disposable radio at this point!

601

VHF antenna length varies on the frequency split that it operates on. With the GP300's, if it is a OEM Motorola antenna, there may be a small dot of paint on the screw base of the antenna. The color shows the split. If it is after market, it may not have this. I have used a high split antenna on a ...

601

I know that the XTN series, the frequencies do repeat on them, I believe mostly the itinerant color dot ones, I'm not 100% sure, but maybe that would apply to the SP21 as well. Not really other much info on the web, I tried looking as well. Hopefully someone who has personally worked with these can ...

601

I think I figured out, seems to be a microphonic issue. When the radio is receiving, you can tap on the front and hear the "echo". I tapped it a few more times and it stopped, and the problem seems to be resolved. It's an intermittent problem, I'm going to take the front faceplate off and give it a ...

601

I'm having a weird problem with my GM300. On 1 repeater channel, I have it set up to send the MDC ID pre, the rest of the channels are post-id. For some reason, the tone that is being generated by the radio (the long boop-beep) is being transmitted over the air. I've tried switching out the mic, the ...

601

Sounds like a dead or defective battery.

601

Yeah, I'm having the same issues with the knobs also. Especially on my MT1000s.I'm probably going to take off the ones that are still intact treat them before they get any worse. The new antennas I purchased were made by Tuff Duck. Anyone ever use this brand? I'm slowly going to replace the genuine ...

601

Well if that's the case, I'm guessing the supplier recently, for lack of a better term, sucks. I know it's a disposable world, but wrapping electrical tape around isn't an option, it's just a personal thing. It just looks absolutely horrible to me. I'm gonna try some of the protectant on the newer ...

601

Ok, so I've noticed a very irritating problem recently, it only happens with my Motorola antennas, a lot of them have began getting brittle and cracking apart. It seems to happen a lot more than before, and it seems to affect the Helical antennas more than the older style ones. Is anyone else ...

601

Ok, as stated before, this is an outside setup. Its going up on a trailer that is a stage and connected to a gas generator. I have an extra 1/4 mount mag antenna, I will definitely try to make that work, hopefully!

601

Not as impressive, but it's an orange P50

601

Ok, here's the deal. I'm setting up a temporary (one day) repeater system for an upcoming event this weekend. I have all my portables and repeater ready to go, but i'm contemplating a solution to the main control area for the event. I'd rather set up a temporary base station for the main control ...

601

I'm really not thinking its oxidation, it's a nice smooth gold surface. I was just wondering if it was anything special, like non-sparking or something like that (explosive atmospheres, I know a long shot) I guess the mystery will live on, just like the huge rock ball that's chasing me now :lol ...

601

Here it is, and I think that huge rock ball is after me now since I moved it off the shelf! lol

601

Ok, I have a silly question that's been bugging me for some time. I have a few GP300's and GP350's, but one keeps on attracting my attention. For some reason, this one has a very shiny gold back underneath the battery, as opposed to silver. Does this mean anything at all, or is it just one of the ...

601

Yeah, apparently the bandsplit was programmed incorrectly, it's supposed to be a 136-150MHz but programmed to a wideband. Guess i'll be doing some editing to get it up to 154. Thanks for the input!

601

Ok, so i'm trying to program a few sabers I purchased from a fellow batlab member, but i'm running into somewhat of a problem. The radio seems to be locking me out of certain channels and I can't figure out why. I've never really dealt with sabers before, the RSS is a lot different than newer stuff ...

601

Welcome to the radio world!

First off, if I were you, i'd stay away from the alligator clips for programming these radios. I speak from experience. One wrong move while the radio is programming and you'll end up with a brick. I had this happen to me. Your best bet is to get an actual programming ...

601

kc7gr - I found this picture online, it was a huge thing at some point for kids to reprogram the signs that were unlocked and had the keyboards still in them. do a google search on "hacked construction signs" for a good laugh. Trust me, I'd have a little fun too if I could, but I don't want to risk ...

601

I just flew from Philadelphia to New Mexico last week. Had a scanner, 2 UHF spirit radios, 1 VHF Kenwood radio, GPS unit, and acell phone in my carry on bag.... Nobody questioned me. I did get questioned, however, about the pack of 4 extra lithium ion AA rechargeable batteries I had for my digital ...

601

Most older 2 channel mobiles are not capable of any type of signalling. I have 2 Radius M130's that do have MDC1200 capability, and they are only 2 ch. I have another that has an added board to give it rapidcall DTMF.

I have a 16 channel mobile that does not do signalling. It was expanded from an ...

601

If you decide to use MURS, go with the lower three 151MHz channels with the narrow banding. Those channels are usually less used, i've used the upper 2 and you get everything from wal-marts to McDonalds drive thrus. A lot of business users are ignorant and think that those are "their" frequencies ...

601

I would highly suggest utilizing the lower 3 MURS channels 151.820, 151.880, and 151.940. The upper 2 are usually full of activity, i've learned this from personal experience. A lot of businesses think that their radios on 154.570 and 154.600 are private channels and they will try to get you to stop ...

601

I think it's been solved, the tessco antenna that FireCpt809 pointed out looks very much like the one I need.

Thanks to everyone for taking the time and pointing me in the right direction, it is greatly appreciated.

601

I need help figuring out what type of antenna connector this is. It's on a GE KRD103 radio. I've done numerous searches online and have not found anything, or a source for this type of antenna. The radio is VHF, but it came with a UHF antenna.

http://i30.photobucket.com/albums/c325/mikeyex626/100 ...

601

Depends on if your unit came with cables.

I used a pair of M120's with a rick with good results. You just have to remember, cooling is an issue, I'd put it with some sort of fan or other cooling measures on the TX radio. I have a big old computer fan hooked up to my repeater, and it works fine ...

601

I was thinking the same thing. We have no idea where it came from, it was sitting in the basement of a fire house.

It says HT RF link, but only has 1 HT440 board in it, with 1 antenna jack. It seems to be a heavy duty outdoor box, minus a cover.

The other thing I didn't catch before was that it ...

601

A friend of mine acquired this unit, I have a general idea of what it is, it has an HT90 board in it, but i'm looking for a little more info on it. Is this unit an actual low power repeater in itself, or is there something missing from it? Does anyone have any experience with these things? It's a ...

601

I've seen the P50's in yellow, and orange (or red, never could tell

).

Once a few years ago I even saw a clear one on ebay, I wondered what that was for.

601

I thought there was an add-on board to give the SP50 MDC capability?

And I have 2 of them that do DTMF PTT ID without a front keypad.

601

I have an HT600 on 500MHz

They did come in T-band.

Not too sure of the MT's

601

Thanks everyone for the replies.

I'm probably going the broadband route. Now, can I use a 1/4 wave antenna with one of those ground plane mounts? I've seen the conversion kits made by antenex. ANyone have any luck with one of those?

601

I'm in the process of setting up a portable vhf repeater system and I have a question about the antenna system. The repeater will TX in the 158MHz range and RX in the 151's, where should the antenna be tuned to for maximum TX and RX performance? Should it tune to the TX freq exactly or in the middle ...

601

Just a side question, are these basically the same as those new cheap M pointed antennas?

As stated before, I use these on my visars, but the range on them is not nearly as good as my GP300's. If that's the case, I may want to change mine out also.

601

Yep, looks just like the VHF antennas I have on my visars. Also tried them on the XTS, they fit fine.

Never heard of them not being bad for any other radio, maybe someone else has an answer on that.

601

I'm not 100% sure, but on newer mobiles aren't you able to change the alert tones? I was able to play with a CDM1550LS+ and in the menu/utilities/tones it had MDC call tone option, with about 5 or 6 different tones. Can those be assigned for QC alerting as well?

601

As long as they're using Quick Call, you should just have to reprogram the radio to RX QCII tones instead of PL or CSQ.

You just have to know what Hz tones they're using and you should be set.

601

If you're using HT1000's or the like, try this. Another member came up with an interesting way to do just what you're looking for.
