I had two HDR-300's in the 90's. The keys went bad every year. I even
tried making my own shaft out of heat treated tool steel. The key still
failed and I eventually sold both rotors.

Thanks to everyone who passed along helpful advice on the HDR-300 - sorry to
not follow up individually.
I swapped in my "backup" HDR-300 on Saturday - will complete the autopsy on
the original one shortly.

Subject: [TowerTalk] HDR-300 question
I installed a well-used HDR-300 last summer to turn a 5 el 20m Yagi (40ft
boom) and miscellaneous other smaller antennas on the same mast. The HDR-300
moves the stuff around quite well but there's 10-20 degrees of "play" in
direction when the brake is engaged. Even in fairly light winds the
antennas always seem to be wiggling around. Not a big deal on 20m but it's
a bit of a hassle with the 9WL 432 beam at the top of the mast... Is this
"normal" for the HDR-300? Any way to fix/improve it?
Thanks,
Fred, N9FH
