GP300 radios will operate either radio-to-radio or in conjunction with a repeater. If your radio no longer works through a repeater, you might check to see if it will work in talk-around mode (radio-to-radio). Check with your repeater service provider to see if the repeater is in working order. One other item which might occur with a repeater would be if your radio is no longer recognized by serial number by the repeater. This is also something the service provider could help you with.

The P110 is a construction grade 2-way radio. It was considered one of the best on the market during the 1990s. It came in several versions, including (but not limited to) VHF & UHF; 2 to 8 channels, 2 watt or 4/5 watt models. If your radios are in good working condition, they would be worth keeping. The only consumable would be the battery pack which needs replaced every 2-3 years. (Sidenote: You can check the battery age by looking for a 3 digit number on the battery. The first number is the year and the next two digits are the week of the year the battery was produced. ie. 945 would be either 2009 or 1999 the 45th week.)

Here is a link to the operator's guide for the P110: http://www.qsl.net/bg4aaf/user/motorola/p110S.pdf

The frequency range and operatngmode of the two radios are compatible. To get the Radius operating on a GMRS channel you'll need a Motorola programming cable and software, OR a trip to a Motorola dealer for frequency programming. Considering the cost involved, the 2-watt output of the Radius, and the 1-watt output of the Talkabout, you would be better off performance and cost wise buying a pair of 5-watt GMRS portables.

There a a few things which could cause this:

1) You have the radio set to an unprogrammed channel.

2) You have a bad, low or defective battery. (Try switching batteries with the other unit and see if the problem goes away.)

3) Your radio needs repair.

4) Your radio has busy-channel-lock-out activated and you are trying to transmit on a frequency which has activity in your area.

Here is what you would need: RIB (radio interface box), HKN9857 programming cable and HVN9128 programming software. You are correct the software is only capable of running on a DOS box, such as a 286 or 386. The software mentioned is Motorola proprietary and is available to Authorized Motorola dealers by subscription only.

The book also shows a cloning cable HKN9755 as being available. Don't know anymore details on it.

Lastly, the cost of programming to your FCC assigned frequencies would be approx. $15 per radio, and less for cloning like models. It might be less expensive to have the radio programmed by a dealer. Just an FYI.

If you are referring to a flashing yellow light on the charging base, this is an error code. Either the 1) battery is bad, 2) not making good contact in the charger, or 3) very very low on charge. The solution for this set of problems is as follows: 1) have the company you purchased them from replace them, 2) clean your contacts with a pencil eraser, 3) leave the battery on the charger with the yellow light flashing for an hour or two. If the battery is just very low on a charge, it will come back to life and the light will change to be constant. If the battery is bad or shorted out, the light will continue to flash and you will need to get with the vendor you purchased the batteries from.

Other things which come to mind are compatibility issues such as you are using a different battery chemistry than you had before. NiCd batteries can charge on either of the two chargers available for the P110 (slow rate or fast rate). However, NiMH and Li-Ion batteries require a fast rate charger.

If you are referring to a yellow blinking light on the radio while it is in the charger. You need to shut your radio off. Radios should always be turned off when charging. If the radio is left on you will never have a full charge. Also, if you inadvertently press the PTT while the radio is turned on, while on a charger, you can cause damage to the radio.

FYI: There is no light to show "out of range" on the radio, unless you are possibly using a trunking or repeater system. A blinking light on your radio indicates the radio is turned on and/or there is traffic on your frequency. Your charger base light can be red, yellow or green. This indicates the charge cycle status. Flashing most always means some type of error.

The GM300 is dealer programmable using Motorola proprietary software, a programming cable and radio interface box (rib). (Or on some models a ribless cable). I will continue to look for a user guide pdf. If I locate one I will post it.

You have to have it programmed by a Motorola dealer. The alternative is to build your own radio interface box (RIB) and interface cable to hook it up to your computer. Plus, you must have the programming software to program frequencies into it. More information can be found here.

If you're intuitive enough, you can find the software online, but for legal reasons I can't tell you where.

Sorry about taking so long to respond. These radios have worked properly in the past. They have increasingly become worse to the point they will not Tx. I have tried to com-cate with a good radio but unsucc. I'm thinking the Tx freq has been altered? Can one freq (Tx) be altered and not the other (Rx) or will both become altered?
