I have a refurbished VHF HT1250 Full Keypad with stored voice board installed. The equipment is out of warranty.
1. It apparently needs a new volume pot installed due to variable volume levels inconsistent to volume knob position. I have the replacement volume pot, but don't know the best way to replace it. Should I take it to a computer repair store or does anyone have other recommendations? I have some soldering experience and would probably be comfortable doing the repair with guidance.
2. I also need to update the firmware from R05.12.02 so that I will have all of the newer stored voice options. I have access to CPS, but no current subscription for firmware updates or the necessary cable.
3. I recently attached two different speaker mics and a surveillance earpiece to this radio and found that audio still comes out of the speaker on the portable. I can't seem to find a fix for this on CPS or the radio menu. Ideas please?
Thanks in advance,
