[aprssig] Thd72a power

[Leonard Revelle]

Not unusual these days. I quickly found that, if I failed to power down during charge cycle, the radio fails sometime during the day. Though I may not deliberately  transmit, the radio will send position packets every 30-min. (if it sees GPS sats) so it will transmit at least 24 times during my normal time with it on a charger. Given normal charge time using 12V. I suspect the internal charge rate is held well below the 1C standard for Lithium batteries given the several hours that charge method takes.
