These might be for sale soon.

I may have too many radios… These two may be for sale soon.
Nothing fancy, certainly not new. Not heavily used or abused;
these are well-suited to become first rigs for new licensees, or as a backup or dedicated mobile/portable equipment to augment existing stations.


Kenwood TS-440S w/AT, PS-30, SP430, 12 VDC cable, mobile bracket . . .


Yaesu FT50-R dual-band HT, AC charger, DC charger, MH34 spkr-mic, belt clip

More detail available of course.

Digital Satellite Ops reference

It has not been recently that I have posted anything particularly relevant to ham radio. I don’t find as much time lately to play with the radios either.
I do however, try to follow several special-interest groups that have internet email distribution lists. Overnight I received an email item from VE6MVP, referencing a research project I have not heard of : Shadow-beacon. In particular, Tony was looking for additional reference on digital operations via satellite. The Shadow-beacon project intends to utilize the APRS infrastructure that is already in place and operational on the International Space Station (as well all over the planet surface via the Internet).

With this in mind I thought I would create a simple page, that provides linkage to several resources that I use on a regular basis. There are surely lots of additional pages that are just as relevant, perhaps you will post some of your favorites in the comment section below. Aside from having equipment setup to operate APRS digital, we need to know what satellites are available, and when and where to listen. Hopefully these links will help answer some questions you may have.

Hidden Treasure

When I first heard of this place, I thought Mike (N4OFA) had been in a closed room with his paint fumes for too long… An old spy-satellite station up in the mountains ? Huge radio telescope dishes ? And they let him pull cables and work on stuff ? Had to be the paint fumes. Over the years tho, I have come to learn more of the history of the old Rosman Tracking Station.
And more importantly, some of what is going on up there these days.
Visit PARI.EDU on-line to find more detail….

So – I introduced myself to PARI and some of the folks there, and have been to visit a few times. On this most recent trip I became an official volunteer, and will be helping to establish more functionality into their Information System Infrastructure management activites, and to further document the networks and the systems that support the PARI mission & operations.

Recently PARI has installed the upgraded feedboxes for both of the 26m dish antennas, and expect to be testing, calibrating, and all that other magic stuff to integrate this into a world-class interferometer. These are certainly exciting times up on the hilltop in Western North Carolina. Hidden Treasure indeed.

I’ll be back to this blog from time to time, with more pictures and stories to tell.
Thanks  /;^)

MakersLocal256 OpenHouse

In celebration of November 11, 2011 (20111111) – the fine folks at Makers Local 256 in Huntsville decided to have an Open House. My good friend Scott was to be cooking gumbo for this event, and invited me to come visit. This is a collaborative learning workspace, and has become quite active. I had been meaning to check it out for some time now, so I could not pass this opportunity. I took my camera and have now finally posted this gallery . . .
Thanks for the GUMBO /;^)
