May be the problem is the ROM the radio will need reflashing, remove the eeprom memory then tray again if the problem persist, the ROM will need to be replaced and reflashed by a motorola depot

If you need to re-program the GP340's here is a link to some software on Ebay. You would need to buy a cable to connect the radio to the pc, but these cables can be found on Ebay also.

What kind Motorola radio is it? and I assumed that you mean main unit and control head. If you don't see an internal speaker in the control head then you need a external speaker hooks up to the back of it.

If your GP340 is a UHF model, YES, you can have it programmed to match your TalkAbout radios. And yes, the GP340 has programmable privacy code capability.
If you do not know if your GP340 is VHF or UHF, you can tell by looking the model number, it will contain the following pattern: __H25RCC4AN3__. UHF models will have the letter R after the "25". VHF models will have the letter K.
When you have your GP340 programmed, the power setting will need to be turned down to the appropriate level to match the TalkAbout radios. Both for legal reasons, and also to protect your TalkAbout radios. You will not want the powerful GP340 to overpower the PA (power amp) in your TalkAbout radios.

Radio off, use moni & menu toghether, start radio keeping the 2 pushed for some time until SELF apears on display. Then insert magic code 5858. There are now 2 values on screen like 136 174 first is lower limit, second is higher limit, after moding ude Enter and restart radio. Remember that at extreme ends pll may not lock on tx or rx or both, this is phisycal limitation of the radio board.
