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. ________________________________ Message 2 _____________________________________ Time: 12:46:51 PM PST US From: "Robert L.

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.

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.
