VHF Contest Award

Another surprise in the mailbox.
On the heels of the 2015 January VHF contest, arrives an award certificate for last year. Seems that with only 13 contacts and 5 grids, I was the band winner in the Alabama Section, Single Op, Low Power category for 222 MHz.

222 MHz Award

This is not the first time I have received an award, for a fairly minimal contribution. I also received this award in 2010, for the 2009 June VHF contest – again on 222 MHz. That time I had 3 contacts in that band, 2 grids. This time I only had one 222 contact, W4ZRZ… Thanks Jimmy..

These VHF contests may not seem like much to many, but I look at them as a mini Field Day. I set up my (mostly) portable antennas and listen a lot as I do other things. This year for the January event I have 17 contacts across 4 bands (3 on 222 this time). I appreciate these little contests, as I get to check in with a few folks I don’t hear much from thru the year. There is always someone new to the VHF contest world, or VHF SSB for that matter… Oh, BTW, these 222 contacts have all been with a HT on FM, but using a small 4 element beam.

50 MHz Squalo and 432 MHz Texas Eggbeater

If you haven’t done such a regional contest yet, try one. Sometimes 50 MHz will surprise you – those are exciting contests when the ‘magic band‘ comes to life.
In the Huntsville area, there are plenty of stations to work, even with just a vertical. Do what you can with what you’ve got.
Get some soon, try a VHF contest.!.

What?_Another blog?_

Almost as though I had too much stuff for just one blog . . .

NetSysHax blog with Wireshark header image

NetSysHax is a blog that was established to offer technical stories and solutions that seem relevant. Alex & I work together during our day jobs, but we both like to offer consulting services when those opportunities arrive. We like to share technical insight and solutions, especially when most problems only need the right tools to become a success story.
Self Promotion needs to be a success story too.

I need to post more stuff on the NetSysHax blog, as well as on this one, my RadioActive site. So bear with me as I work on both in parallel (with appropriate cross-links).
Thanks.. Please visit often for new stuff
(or – you can subscribe, and receive email notification of new posts…)

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.

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.
