Pending Tracker2 install

The Tracker2 arrived in VK6 a couple weeks ago but there were delays getting it into my hands. Thanks to VK6LD Rob for managing the shared order and Danny VK6ZUK for transporting from Denmark (the township, not the country :-)
Installation of the Tracker2 is this Saturday, 9/10/2010. We are having a general APRS workshop where club members can get involved with the install, see a selection of various other APRS gadgets and ask questions about APRS, what it's for, how it works etc.

We've also started on the installation of the Ultimeter 2100 weather station which has stalled due to cable routing issues. An extension ladder and impact drill will be needed.

It has been discovered that the PSU currently powering the APRS transceiver is generating noise on HF. This is not good since the shack is set up primarily for working HF. There are squeals every 40 KHz or so under no load and the whole HF band is pretty much splattered out when it's under load. I suspect that the reclaimed regulator board in the PSU might be a switch-mode although it didn't look like one. There is no HF noise when the APRS is running from battery. Bugger. I'm working on a replacement. Managing 4.5 amps with my current supply of transformers and components is tricky. I'd rather we didn't have to spend more money.
