Hello, I'm Greg Albrecht, W2GMD.
My contact information is as follows:
I operate several APRS stations, some personal and some experimental.
A Digipeater/IGate & Weather Station in the Outer Sunset, San Francisco, California, USA, with a 6.5 dBi gain VHF antenna at 56 MAMSL.
This station is strategically placed to pick up all western San Francisco and near-shore Pacific Ocean APRS traffic. Because of it's clear view west to north-west, it's been known to pickup trans-Pacific balloons as well.
My primary vehicle (Black 2016 Toyota RAV4 Hybrid).
Other systems I operate (amateur and otherwise):
