I emailed Bob and asked him if it was ok to encase the transmitter in silicon to weatherize it. He said no problem so the transmitter is weatherized now and works great. I think I am going to attach it and the antennae to a parachute cord. I can sew the antennae up and down the cord with the transmitter located in the middle. This should keep the dipoles separated well and upon landing keep them off the ground.
I'm also going to build a 555 timer in order to delay the DF transmitter power up. I want the signal to initiate upon landing in order to minimize interference with the aprs tracking signals.
