SOURCE: my customer has 6 motorola max trac vhf radios.

If this is a new install, it is likely noise from the vehicles electrical system scrambling the processor of the radio. Put a filter on the power leads and check your install.

SOURCE: 18 miles max range but actual it can transmit and

The reason for this is due to various possible conditions. The first being obstacles in the operation range of the unit. IE> hills buildings trees ect. This can greatly reduce the actual distance the unit will work in. The 18mile max is probably a rating that would apply in the best opt. scenario. You would have to be on a flat terrain with no hills or valleys,no trees or buildings for the unit to reach the max distance. In dense areas of trees,buildings or uneven terrian you wont even come close to these distances. Second: any unit RF unit that is held in your hand or close to your body does cause the antenna to detune to various degrees the amount that it does depends on how well the unit has been designed. The more it detunes the less resonated frequence is recieved and amplified making for a weaker signal. In conclusion for the best long range reception be clear of as much surronding interference as possible and as high a possible above any elevated terrian

SOURCE: my motorola MH230R radios won't

Try to clean the contact point of the antenna of both the transceiver. There might be a foreign object which clog the signal to be fed...if the problem still exist. The possible reason is one of the transceiver has a defective amplifier circuit...
Call a technician to locate the repair the problem
