Currently I'm only powering a 2 Meter mobile rig transmitting at 5 watts. I hooked the meter directly to the interior pos and neg posts of the Astron. I'm not sure how accurate the meter is, it's a 'red' meter from China. The drop from initial turn on to the 13.64 reading occurs over approx 20 mins.
This is no big deal. I'm not 'itching' to adjust the output voltage, I was just curious if this was normal and would have any performance interactions with any connected equipment. Picture link is below..http://i932.photobucket.com/albums/ad165/lfeissner/0806102335.jpg
