Yes you are right about it making the HamAm accessible Pat. I
too have gone over to wire and vertical antennas, and have no
idea to whom I gave my old HamAm indicator. Guess I'll just go
howl at the moon, if and when I can find the direction where it
is. I don't even know the current phase. Hmmh, I'm a bad dog
bad dog! Jim WA6EKS

Subject: Re: Audible rotor direction indicator
jim,
Handihams provided a very similar indicator. I used one on a
Ham-m
rotor for many years. i put mine away after we moved and i moved
in
to the wire antenna age; promised the indicator to someone on the
list and darned if I can find it again!! i found it on a shelf
one
week and when I went back for it again, it had vanished!! I'm
guessing it was the man in the moon took it! But it sure made
the
Ham-m accessible.

I don't think I have commented on this thread, but back in 1975,
I had a HamAm rotor that turned my HighGain TH6DXX 6 element
beam. There was no way for a blind person to know the direction
the antenna was pointing because the rotor meter was of course
under glass and probably had a very small needle. A friend at
the time, built a small device, seems it was a voltage controled
oscillator with a pointer knob on top that rotated freely 360
degrees. I would set the pointer in the direction I wanted to
point the beam and hit the keys on the rotor. When the tone in
the speaker inside the attached box nulled out, I knew I was
pointing northwest or where ever I needed to point. I am not
aware of any similar audible rotor indicators out there today.
