We have used this radio system for 8 years for our taxis. For the last 4 days we have had a great deal of interference. So much so that on many occasions all we hear is a crackling noise and cannot hear the operator speak. There is an orange light coming on which was previously green when the operator spoke and red when the driver spoke. Can you please help us solve the problem. Thank you

Re: interference using maxon pm100 2 way radio
Hello susannebrown. There is a problem with the base station or repeater station. If your mobiles can communicate ok, you have problem with the base, check the antenna & coax connections. #2 Swap out a mobile with the base & test operation. If you can do this & found the culprate care it to the repair shop(less cost). #3 Swap has no effect or you can't, you have a repeater problem. Sorry, call a repair shop.

What you have been using are consumer grade walkie talkies. The rechargeable battery packs in them should last a full business day, unless you are in a high use area. This being said, it is also possible you might need to replace the rechargeable battery pack as they usually have just a one year life expectancy. As they start to fail they will go less and less time in a day.
To answer your question about a radio which will go a full business day, any of the business division Motorola handheld radios would work. Radios such as the CP110, BPR40, CP185, and CP200 are all make to go a full day and sometimes more. Their battery packs depending on chemistry would also need to be replaced every 18-24 months.
Mike the only suggestion I can giv you is to contact Maxon or a local dealer asn ask for replacement parts. The radio shop I work for does not carry maxon or Altronics parts. I only have Motorola and Kenwood commercial radio parts.
THE SP100G is essentially the same radio as the SP100U UHF business band unit that Maxon made at the same time, just pre-programmed for GMRS. I believe there is a programming kit for this radio (Model number: SPK400C) which may still be available for purchase from Maxon directly. Otherwise, your best bet is going to be contacting your local Maxon dealer to see if they have the capability to program he radio.
The Maxon SL100 can be programmed but doing so requires a programming kit including software and a specialized cable. Unless you are going to be reprogramming a lot of units regularly, you are going to be best served by taking the unit into your local Maxon dealer and paying them to reprogram it for you.
I'm not sure about your particular model but many CB radios use the microphone push-to-talk switch to kill the speaker while the radio is transmitting. If you don't have the correct microphone or if the cord has a broken wire it can cause the radio to have no sound. Another possibility is that the speaker is bad. There is probably an external speaker jack on the back of the radio. You could try plugging a different speaker or even an earphone in the jack to see if you get sound there.
