    I dragged my unfinished Johnson Viking II modification project out of the cobwebs and thought I would finally finish it up and start using it again on 10-meters. I had everything done except for solving the 6146 grid bias supply issue. I want it to use grid leak bias, but also retain the fixed saftey bias. That's all I had left to do along with adding the negative peak limiter.

    I also have another unmodified NC-303 receiver I thought I might pair up with it for a while on the other side of the shack.
