DR-135 3.5mm plug polarity
I have a DR-135 (MkI I think) that I just put a T2-135 board into. I
had the Alinco TNC installed before.
I have discovered that the 3.5mm front panel data jack has pwr and gnd
reversed (i.e. Ring = gnd, Sleeve = +5V).
I reset the radio to the initial settings (power up with FUNC button
depressed). No change in data jack polarity.
Is there a more thorough DR-135 reset or another trick to get the jack
Thanks - Erik / N7EQ
