BG105418471 Aftermore than 2 months of usage I have some more facts to notice:
- best mod is adding a On/Off switch on battery circuit. Otherwise battery is drained in less than 1 week ))
Of course will be empty when you try to tune for a exotic DX, according Murphy law.
- without charging indicator let battery to charge more than 10 hours.
