[TenTec] Re: Help with Scout 555

[Tracy, Michael, KC1SX]

Don,

I bought a used 555 from Ten-Tec early last year and found the tuning to be stiff indeed, even for a PTO design.  Bravely (foolishly?), I took the thing completely apart (this took some doing) and found that the PTO was spring loaded, with three small plastic spacers to give the spring extra compression.  I took out two of the spacers and reassembled the rig, only to be greeted with no audio output because I had forgotten to plug one of the cables back in (and I had to take the rig mostly apart again to get to it).  I was mostly satisifed with the resulting tuning tension.  

Some months later at a hamfest, I picked up a mil surplus knob that was a *perfect* fit for the Scout and has a finger indent, further aiding tuning ease.  I found it was hard to locate a small enough knob with an indent, but they are out there.
