if anything is listening on that frequency in Seattle. My results with
an RTrak with a rubber duck or quarter wave right on the RTrak, with or
without an additional ground plane were abysmal. However, as soon as I
went to a half wave mag mount, performance (at least where I live) was
as good as a tracker using an OT1x and an FT-1500 running 10W connected
to a 5/8.
I know you have verified that your RTrak is transmitting, but having
another TNC and radio for testing would be really useful. If you don't
have a TNC, are there any other APRS users close to your location?

flash a double-red while the GPS is acquiring and a single green after
it has a fix. It be red when it transmits.
