I was frustrated because I could not receive the list.
I pursued Comcast at least five or six times and held for ten to fifteen minutes
until I finally got some one that knew what they thought was going on. It
was a supervisor's supervisor. He told me there was something with Matronics that
did not agree with their format. I switched to G-mail and it has worked great.
I e-mailed Matt the info. Then about a week ago I started getting it again
from Comcast. So I guess the problem has been fixed.

Is this a vhf only ELT? If it
includes 406MHz capability, then
you're advised to use the stock,
dual band antenna recommended for
the ELT.

This would be too close to expect
insignificant interaction.
Recommend you consider the built in
antenna for the VHF Comm and a
ground plane vertical whip for the
ELT.
Much more likely to achieve optimum
performance.

And with the dipole in the tail, the ELT ant could be fit farther
forward inside the fuselage (for separation) with its own 1/4 wave
ground plane.

| Subject: | Diagnosing generator problems |
I have a friend with a 1946 Swift that is having generator issues. It isnt charging
the battery. Are there some easy checks that can be done to try and narrow
down the search for the issue ie: voltage regulator vs generator etc?
Any feedback would be appreciated.
Randy
