MFJ-1278B question - PTT of power off
I have an MFJ-1278B interface that works fine but when the power is removed
from it, it keys the transmitters PTT line. I'm using it with a Kenwood 2000 which I don't think matters what radio it would be used with since it is going to ground on removal of power. I don't have a manual for it since I bought it off Ebay but it did come with the standard 1278 (not B) manual which appears to be a good bit different. Anyone have any idea what might be going on?? Tnx and 73, Ken, WS4V See QRZ.com for email address if replying directly. |

I'll then scan it in and email it to you. 73s Mark MFJ has many of their manuals on line in pdf for free downloading. |
