My ASAC (Am-Comm) controller acted/worked like yours.  My Screwdriver
antenna is mounted rear driver side of a GMC pickup.  Originally I run a
hefty ground to the frame to the ant. base ground point.
After a ground strap was added from the base to the closes sheet metal
(about 6 inches long) and all the problems went away.
To make it short as possible I opened the tale light assembly.  Removed
paint inside, used 3 machine screws with double star lock anti-ox and
mounted  2 inch copper strap.  At the antenna end, disassembled the feed
point and attached the ground there.  Mine uses a cone arrangement with a
screw washer and nylon washer.  The ground strap was punched with a large
hole and mounted (not using the manufactures ground point provided) but
between the nylon washer and ground side at the feed point screw.  The strap
was run between the joining edge of the fender and plastic tale light assy.
My 706 and ASAC are mounted under the seat where I also ran a short ground
lead (-12 V side) unit to unit about 6 inches.
I'm not a great writer but hope you understand the above.  Before I got me
ground problems fixed I would have given my ASAC away to someone I disliked
for revenge.  I have been using it this way for three years now with no
problems on any band.
