[TowerTalk] HDR3-00 on the AS455G shelf?

[Doug Renwick]

The keyways (2) are the Achilles heel of the HDR-300.  I haven't seen
the new redesigned shaft but I redesigned my keyways and it has solved
the problem.

I'll run the race and I will never be the same again.

I am curious as to what antenna configuration wore out the keyway. I
have 3
HDR-300's (one with a control box issue that needs to be resolved) but
have
never had one in service. I have a KT-34XA (with some M-Squared
upgrades)
that may go on one '300 and at least a long-boom (40+ foot) six meter
yagi
and a 3.2-wavelength 2-meter yagi on the other. Are either of those
configurations too much for the '300?

Yes, I am in a wind-prone area of northern Nevada where 30-40 mph winds,
with gusting above 50 mph, are not uncommon.

73,
