The Santa Barbara Amateur Radio Club (SBARC) will be featuring Jim
Knight and Jim Woolaway as our speakers for the October 15th meeting. As
two of the founders of Indigo Systems, they are both very familiar with
infrared technology and will be sharing some of that knowledge at our
meeting to be followed by a Q&A session. The meetings are open to the
public.
Our meeting will be held on Friday, October 15th at the Goleta Union
Schools Admin. Board Room, 401 N. Fairview Ave., Goleta, CA starting at
7:30 PM. More information about SBARC can be found on our web site at:

Imaging in the 1 to 10 Micrometer Band
By Jim Knight WA6RNV and Jim Woolaway AE6AC
We are all pretty familiar with radiation at wavelengths of 160 meters
to 70centimeters. Some of us have worked shorter wavelengths but how
many of us have an understanding of what radiated signals are like at
the 1 to 10 micrometers wavelengths? Jim Knight and Jim Woolaway, both
SBARC members and HAMs since 1970, have spent the majority of their
professional careers working in the field of Infrared technology. They
have seen the state-of-the-art in infrared cameras move from what once
was the size of a VW bus to the size of a small saltshaker today.
Knight and Woolaway will talk about radiation in the 1 to 10um band, how
infrared technology works, and demonstrate the imaging of this
radiation. Did you know you are already radiating in this band? Come see
what your signal looks like at 5um.
I hope to have fixed the following:
- no more double ID announcements
- shortened the ID announcement a tad
- revert to CW ID if voice ID is keyed-over
- issue forced ID as CW, not voice
- ensured no ID is sent out IRLP
With respect to the last problem, I was told that folks got complaints from remote IRLP sites that our controller was transmitting IDs on IRLP. This should definitely not occur! I could not reproduce the problem nor really tell how it could occur, so please let me know if anyone gets further complaints.

One .. small .. step .. at .. a .. time ..
We finally have a Winlink TelPac node up at La Vigia Hill on 145.05. This is software that gateways between the RF side of the Winlink system and the Internet side. Unfortunately Bill and I discovered that the old packet hardware that was there had deteriorated badly, in particular the 438.950 9600baud radio seems to no longer function. So for now all we have is the single 1200baud 145.05 radio operational.
If you want to try things out you need to install Paclink on your computer and set it up to connect to K6TZ-1 on 145.050. The best step-by-step instructions I have seen are at <http://www.ki5dr.com/images/wc-ares.ppt>. Let me know if you run into difficulties.
The K6TZ-1 node sends out a beacon every minute to USERS, so bring up a monitor window as soon as you dial the frequency and you should be greeted with "K6TZ-1 Santa Barbara La Vigia Hill Winlink 2000 Telpac node".

Hi,
I'm finally finding a little time to work on my backlog of radio projects.
What this means is that I am getting motivated to get an inexpensive
spectrum analyzer. My budget is very low, but I've seen a few on eBay that I
can probably afford. I know there's a lot of knowledge and experience out
there, so hope you can give me some good advice. What should I consider and
what should I stay away from? Are there any good deals you're aware of?
Obviously, I want everything for almost nothing, but these are my
requirements:
1. Coverage of ham bands from 2 Meters through 10 GHz
2. Usable frequency display, digital desired but not required (OSD or
not, either is ok)
3. Stable and fully functional but not necessarily absolutely
calibrated (I'm willing to use fudge factors for calibration errors as long
as they're minor and predictable)
4. Display quality not noticeably degraded
5. Some type of computer/printer output desired, but not required
6. Tracking generator desired, but not required
7. Popular make and model so parts and information are readily
available, newer is better
8. Capabilities and functionality are more important than cosmetics
9. Portability is desired, but not required
10. Price below $1000, preferably below $500
All help is appreciated,
Rod, wb9kmo(a)sbarc.org
The packet node at La Vigia is currently down (since yesterday noon), this affects the 145.610, 223.680, and 438.950 frequencies there. Bill and I replaced the old PC controlling things by a Win98 box that will run TelPac (for Winlink). Unfortunately getting it to work with an old dual-TNC ISA card that has no documentation and an MFJ-1270+MFJ-9600 TNC for which I can't find much documentation either and whose RS-232 appears to be acting up is a little "interesting". I'll get there, but if anyone wonders why it down, this is it...

Note that the new system will use 145.050 instead of 145.610.
I still have one of those boxes. They are a little bigger than that cubic
foot and weigh in at ~70Lbs. also They are fetching $5000 and up depending on
the plug ins. To do what Rod wants to do you would need a display frame an IF
plug in and probably 2 RF plug ins. It would go from HF to 18GHz. To get the
most from them you need some additional boxes, like tracking oscillators or noise
generators. There are now several do it all boxes from HP and Tek and
probabaly some much less expensive stuff for the communications serviceman from
outfits like Sencore. Good Luck Rod, but don't expect much for $500. There are
now a lot of kits for many good devices around, it's just finding them that's
hard.
