I recently purchased the FTM - 7250DR dual band mobile and i love the radio. However, I am having problems with the memories not maintaining the information programmed into them. Specifically, memory channels 1-6 work fine, so I know I am doing it correctly. Channels 7 and above all lose the SQUELCH TYPE information once the channel is changed. Example - i set a channel with a SQUELCH TYPE of "TQSL" and a TONE FREQUENCY of "100HZ". As long as I do not change the channel, I can talk through that specific repeater with no problem. If I move to another channel and then come back, the SQUELCH TYPE reverts to "off". The TONE FREQUENCY information is still there, but obviously it doesn't make it to the repeater so I have to reprogram the SQUELCH TYPE again. When scanning and operating mobile, this is not a tolerable situation. Anyone have any insight into what might be causing this? TIA.
