[Johnson] more Ranger adventures

[Glen Zook]

Unfortunately, if the Ranger was factory built, a lot of the ground lugs, all the tube sockets, etc., are held in place by rivets which do work loose and/or become corroded over the decades.  Those that were "kit built" have machine screws.

One problem with the Rangers is that the VFO is on the operating freq for 40m.  They are prone to getting RF feedback when doing that, which will cause symptoms like yours.  You need to be mechanically tight, loosen & retighten all screws, particularly those for ground lugs and shields, including those at tube sockets.  I'm sure there's some info back in the archives of this list that speak to that, it you can't find anything easily, let me know, I'll dig in my stuff. I had the problem badly in a Valiant, and ended up making a sliding ground for one tuning shaft that went thru the panel & wasn't well grounded. You can read abt that at <http://www.boatanchors.org/valiant.htm>  The Ranger may not have that particular cause of problem.
