Hello, I'm Greg Albrecht, W2GMD.

My contact information is as follows:

APRS Stations

I operate several APRS stations, some personal and some experimental.

SUNSET

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.

  3. Alinco DR-1200T
  4. Comet GP-6 Dual-Band 6.5/9 dBi Antenna
