Paul, Roy,Thanks the replies.? In the past I have always heard myself.? So
there must be something gone wrong with my system.? I will have to check out
everything.
Thanks again for the suggestions.73s, Jim, Ke4kol

In case you haven't already tried it, try your lowest power setting too.

Shouldn?t matter, I?ve run my 910 at 50W+ without a hint of desense on
SO-50. N8HM is right, the 910 has superb filtering so I would definitely
break out the analyzer and check out what?s going on with the antennas and
feed line.

Is the Alfa-Spid stepper motor based? Certainly the feedback is digital.
But I could certainly imagine a bunch of fast steps sounds like a beep.
My G5500 actually makes a slightly odd noise too. I sounds almost like a
clock being wound. I'm guessing it has something to do with the brake??
Does the A-S have one?
Maybe sound insulation is going to be your best bet.

If it is the ramp-up PWM modulation, then I guess worst case is to somehow
put a muffler box around the motor to keep the neighbors happy. But the
vibrations are probbbly well couipled to the shafts and antenna system, so
just muffling the motor might be not as effective. Wrap a towel around
the motor for a quick test and see how much that attenuates the noise.

I contacted Jeff at Green Heron Engineering this morning. He suggested I
set the Min Speed of both the AZ and EL in the motor control to 10. This
stopped the buzzing noise(that only I can't hear). I then had my Wife take
position under the antenna system as I adjusted the Min Speed slider to get
it as low as possible. It was set to a 3 on both when I started and now I'm
at a 8 AZ, and a full scale 10 on EL. This fixed the noise problem, but now
the rotor doesn't point as precisely as before, it will over shoot around 2
degrees or so. This is fine with my M2 Leo pack. Thanks Kevin. And Burns,
you just reminded me how much nosier the 5500 is, much louder the AlphaSpid.
All is once again well in KB2M land ?

Glad to hear GH was helpful and that you found a solution. Luckily, my
G5500 is not close to anyone, so I'm the only one that hears it if I happen
to be outside :-) We certainly need to pay attention to our neighbor's
sensitivities, especially now the we are all home more!
Thanks for the update!

I?m setting up a Kenwood TM-D700A for use on the FM birds.
I?m having issues to getting it to work full duplex. Could someone post or
send me a copy of the settings they are using for their working setup?
Thank you, 73,
