Well, I'm telling a story on myself. I had looked at your page before and added it to a folder with Ranger related info from several places on the web and BAMA, etc. I've been fixing various things as I go through this rig. The latest item I was concerned with was the modulator current (way too high). So I was looking to see what other people had done and looked over the grid biasing for the modulator but missed the variable screen voltage power control (a future project).
It used to be routine to try to get 120% positive modulation in broadcast AM service. Still not a bad goal. Thanks!

Here's some more info: http://www.w3am.com/ranger.html You don't have to do anything other than the screen mod if you don't want to. This is just one option for you. g Patrick Thompson wrote: > Thanks to all who replied. > > If I go the route of lowering screen voltage is it enough to lower just the > screen on the 6146?
