Hello, I have the?barometer board installed in my VX-7R and the radio sets, in off condition, for several months before I turn it on again with no battery drain problem. First check to see if the timer feature of the VX-7R is off. The VX-7R has the ability to turn its self on or off at a preset time. Refer to the attached photocopy of VX-7R Reference Manual. if that is not the case,?You could use a different fully charged battery, check the level, install it in the radio, with the radio OFF, let it set for a week, then remove the battery and recheck the battery level.? If there is no real level change, then your problem may be, the first battery is bad and needs rebuilt or disposed of. If there is a drainage on the battery then your radio is in question and needs trouble shooting. You could also check the battery in question by fully charge the discharged battery, then set it aside for a week or so then after that time, check the battery level. If the level changes significantly then the battery is in question. Without hands on to troubleshoot the radio, it is hard to come up with an answer. Clyde KC7BJE?
