[TowerTalk] HDR-300 INFO

[k3hx at juno.com]

Had the HDR-300 some years ago.  

The "brake" (a grey thing, supposedly held in place with a setscrew) fell off and allowed the antenna mast to windmill.  Had to change out 7 lines in the winter at the top of a 60' tower. I was not amused. 

I'd recommend putting in a stainless steel setscrew to replace the original and after it has been tightened, running another stainless steel setscrew down on top of it to act as a "jam-screw."

Also had fierce QRN coming from the display.  Fixed it by wrapping the 
flat cable that goes to the display from the circuit board in aluminum foil.
