[TowerTalk] Hy-Gain HDR300 Rotator - Brake Release Solenoid

[Bryan Swadener]

Thanks Patrick, 
However, the solenoid coil is encapsulated. I've rewound stuff before but, this is tiny (about 3/4" diameter x 1" long). At 32 Ohms DCR, that's REALLY tiny wire that I don't have. I have since identified four possible solenoids from Guardian Electric that *may* retrofit. And then, a TT person has offered to supply the OE solenoid. Thanks Doug! 
And in all this, Craig (Rotor Doc) has been most helpful with historical information about the HDR300. 
tnx es vy 73, Bryan WA7PRC

Maybe a PITA but perhaps you could unwind the coil while counting turns 
and rewind after fixing any breaks in the wire or use new wire.
