My 6300 runs from my 12V (13.5V) battery backup system, and I'm wondering whether the 6300 draws a small amount of current when it's "off." If so, how much?
If current is drawn, I'm also wondering whether part of this is the TXCO drawing current to keep the crystal at a stable temperature? Or does the TXCO start off "cold" upon turn-on.
The 6700 has an OCXO (oven controlled crystal oscillator) which has a small oven that keeps the crystal at a specific temperature when the rig is shut off, as long as you keep 13.8V applied.
There was some confusion/misinformation about the OXCO being powered when the radio is off. But according to Steve H. it is not. See the discussion at this thread.
