I have had a couple of BTech GMRS V1 HT's for a year and they seemed OK and work well with our Midland MXT 115's and MXT 400's. Just before the warranty ran out I noticed that one of the units had a dead battery, even though the power switch had been off. I charged it back up and noticed that over a three day period it drained the battery with the switch off. Thinking the battery was defective, I put in a warranty RMS and was just about to send it back when I got to thinking that maybe it wasn't the battery, but maybe it was somehow drawing current when off. So I set up a current flow test between the batter and rig and sure enough there was a continuous 15 ma. discharge. So I got another RMS and sent both the unit and the battery to BTech. They replaced both in short order.
Then I discovered that the replacement unit did not have the FM radio receive function. I actually find this useful as another use for the radio. Upon contacting BTech, they indicated that I needed to enable the function with CHIRP. I ordered the cable and it turns out that the FM function is enabled, so something else is defective. I wrote to them several times but they are not very good about responding but finally asked me to request another RMA. I tried that but by then the warranty period had run out and the system would not let me request an RMA due to being out of warranty. So I again asked them about this and they said to "edit the date on the RMA."
It costs around $7 or so to mail these units to BTech and I am considering just living with the disabled FM function. Hopefully no other problems exist that I have not noticed, but it has been disappointing.
I am thinking that it is possible that this replacement unit may have a physical issue with the button not engaging the internal switch that switches the FM function but I am hesitant to disassemble it.
Has anyone else had a problem like this? And/or has anyone tried taking one of these units apart?
Thanks for any help.
