Subject: Don Lucas, W0OMI, In Memory of
Message-ID: <v01530504af1503a16d71@[]>

This is a sad message.  Don Lucas, w0omi, died on 15 January.  Don was
responsible for development of the CAPMAN HF propagation program used by
many contesters (and DXers).  CAPMAN a 'ham-friendly' desendant of IONCAP,
I believe to be the base for the QST HF predictions.  Don was an early and
continuing worker in applying digital computers to radiowave propagation
and was an author of many Institute for Telecommunication Sciences
publications. In recent years he was associated with LUCAS Consulting.  He
was a former Navy Radioman and a long time active Ham with emphasis on 160
meters.  It was my privledge to work with Don for many years on HF radar
performance modeling.  Don will be missed.

Subject: antenna-free CQ WW 160
Message-ID: <199701291535.KAA20570 at web.gmpvt.com>

Yo to everybody!

In the CQWW 160 contest my tuner settings were all wrong and
the band seemed kind of dead, so I decided to run 100W and try to 
work someone.  I figured the ice and snow must have goofed my antenna.

I made about 100 qso's, including a couple of DX, but it 
was rough going with lots of repeats and no answer to my CQ's.

Then I pushed the meter back-light button on the tuner and got 
nothing.  Just my luck, the bulb was burned out.  Then it hit me,
duuhhh, that maybe there was no power to the tuner, which means 
no power to the antenna relay box out on the side of the garage, 
which means no antennas.  Wiggle the 12V cable.  No lights.  Change
the 12V cable for another one.  Lights on, loud signals, lots of 
answers to my CQ's.

So, I worked the CQWW 160 with 90' of RG-8X, unterminated, laying
on the ground.  But, it's a great location.

Remember if I get any scores with only Single Op or no class on it I will
put you in Single Op High Power.

I realize there is not such class as MultiOP/LP. It is only for the guys
who want to see how they placed against each other.

Thanks to everyone who pointed me to Richard, K5NA, as the
source of the original work -- too many responses to thank everyone
individually.   I am somewhat embarrassed that I didn't remember 
it was him, since I had planned to visit him in Austin at New Years 
but was forced to postpone the trip.

I received a number of requests to post any information that I
might learn so I have included a compilation of the exchanges
with K5NA--who still has some of the units left for sale.

I also received some responses about networking with Ethernet
and these responses were beyond the scope of my inquiry.  
The current logging programs do not support ethernet and
my main goal was to eliminate the electrical connection
between the different computers, which is only possible with
fiber optics.

Hope the info is useful--73  John W0UN


>A few years ago, at Dayton, I believe, someone talked about networking

Hi John. That was me. I had been having trouble with near-field RF from the
80M and 160M antennas locking up computers running CT while doing multi-op
efforts. I determined that the RF was getting into the systems from the null
modem cables between the operating position computers and/or the
PacketCluster computer. I even tried null modem cables with separate
shielded wires to no avail. So I started looking at fiber optics and

The results were terrific. We operated the 1991 CQWW CW contest as a
multi-single using four stations/computers networked together with the
PacketCluster and all our computer problems seemed solved. We even won the
M/S category that year.

>Does anyone know:
>1)  Who was responsible for the design and marketing?

I think there are a lot of comparable units out there. What I used was
Thomas & Betts multiplexers that are about the size of a DB25 connector.
They plug directly into the back of the computer into the COM port. If your
COM port was 9 pin, a 9 to 25 pin adapter could be used.

>2)  If they are still available?

I think you can stll buy them through Allied, Newark, or some of the big
electronic supply places. I sold them for a couple of years while I was
living in New York,  but I have since quit trying. My mark-up was low and
amateur radio operators hate to spend money so it wasn't a worthwhile thing
for me to continue to do. I still have a bunch of them as a result of
over-enthusiast stocking. I occasionally sell a link to old customers or a
friend, but I am really not in business anymore.
>3)  How they have performed?

Just terrific. It took care of almost all my computer hangs due to RF

>Any information--especially technical details-- would be appreciated.

Let's see. They operate at DC to 19.2 KB/Sec. Full duplex using duplex
plastic fiber optic cable. The plastic fiber is 1mm in diameter and the
connectors are easier to align than the glass fibers. It was fairly easy for
me to cut a length to order and attach the connectors. Downside is that the
plastic is limited to 200 feet maximum length, while the glass is good to
5000 meters. 

The multiplexers requires 9 to 12.5V DC, both plus and minus (I also sold a
little wall transformer that took care of this). But you could wire the
power requirements to the COM port pins from the computer's PS if you were
so inclined to do so. I also sold a mini-din, if you wanted to use your own
external PS for it.

The units multiplexed TX data, RX data, RTS, CTS, DSR, DTR, and a couple of
others that I can't remember. The light source was an LED.

If you have any other questions, just ask. I have the data sheets for the
multiplexers out in the storage shed and I will dig one out if necessary. 

Expect to pay about $50 to $70 per unit for the multiplexers and $0.40 to
$1.00 per foot for fiber optic cable from a retailer. The price range is
dependant on whether you are buying plastic or glass fiber and the speed of
the multiplexers. My guess at prices is based on my research of products
from 3 or 4 years ago.  (I think the fiber optic cable may be somewhat 
cheaper now.   ---  W0UN)

I forgot to mention cable connectors above (usually ST-type). They can be
from $5 to $10 apiece. If you are using a duplex cable system as I am, four
connectors are required for each cable.

>Richard--one more thing.  Your system was designed to support 
>the first CT interface where two serial ports were used on each 
>computer, I believe?  And they were rigged in a single line.

I didn't design the system to support CT. I just found the multiplexer
devices and applied them for use with the program. Originally for CT, each
single computer link required a serial port connection at both ends. The
first and last computers could have only one port (being at the ends of the
string) but all the computers in between had to have two. Another way was to
have some computers with four port COM boards and you could "star" out the
links from there to computers with one COM port. But I think you know what I
mean. Standard CT networking setup.

>Later CT was able to use one serial port with RX of one computer's
>serial port was hooked to TX of the next computer's port until the
>system was in a daisy-chained complete loop.

Yes, this was added later by K1EA. I believe it was called "loop" mode. I
know it can be done with the stuff I sold because I sold a number of links
to Paul Young (K1XM) of the YCCC for his DXpeditions (J39A, etc). He ran
loop mode and I believe he built a junction box to jumper the TX Data lines
to the RX data lines while running three or more computers that had only one
COM port each.

The plastic cable is duplex cable with separate connectors on each end (4
total connectors) and there is no reason you can't peal the duplex cables
apart and run the single cable from TX Data port of one computer to the RX
data port of the next computer. That way you could loop any number of
computers using only one COM port, with one multplexer per computer, and
about half as many cables as the other configuration. The only problem would
be that all your duplex cables would be split if you wanted to use them
later in the conventional way.

>Is it true then that yur system requires two of T&B units per computer?
>So the price per system might run from $100-$140 plus fiber and use
>up two ports?  Any thoughts on implementing the newer system
>that only uses one serial and needs seperate Tx and RX fiber?

I think I kinda answered that above. If you are only using two computers,
you only need one complete link (one cable and two multiplexers). If you use
three computers in the original fashion, you need two complete links (two
cables and 4 multiplexers). However, If you use the loop mode with three
computers, then I suppose you would only need three multiplexers and 1.5
cables (three halves of dulpex cable). I have never tried that configuration
myself, but I think it should work.

I have been selling my stuff at cost lately. That means I would sell a 20
foot link of duplex cable with four installed connectors, two multiplexers,
and two wall PS units for about $125. I usually got $172 for that package.

BTW there are two types of the multiplexer available. One for
computer/terminal connection (DTE type) and another for modem/tnc connection
(DCE type). I don't know if you are familar with these communications terms
but it simply means that the TX Data and RX Data are on different pins
depending on the type of computer equipment you are connecting to. They are
functionally the same and by using a Radio Shack null modem adapter, you can
use any type of the multiplexers anywhere.

Someone told me the DSP is not in the AGC loop. Therefore the notch is
also not in the AGC loop even though it is at IF.

Subject: Inverted-L, feeding from top?
Message-ID: < at marel.is>

My short/low horizontal wire didn=B4t do a great job
during the CQ 160/CW last weekend.  My next plan was
to put up a half wave horizontal wire at 15m/50ft
for the upcoming topband/SSB and the ARRL DX contests.

Several of you guys have advised me against a
horizontal-only antenna for 160 and suggested an
inverted-L.  Now, the only practical way for me to
feed the inverted-L from my attic shack location
is into the horizontal part (the very end or
somewhere off the end).  I would appreciate any
comments on this, including the questions:

1. Has anyone you know done this?

2. What do I do with the bottom end of the vertical
   part?  I would think it should be connected
   directly to the radial wires I would bury in the
   ground.  An alternative is leaving the wire just
   suspended a little above the ground, but I suspect
   this will give me low current in the vertical
   section - and correspondingly low radiation there.

3. Any comments on how to feed the horizontal part?
   Tuning out reactances, etc.

4. Any comments on the desired length of each
   section?  I guess most would say "the longer the
   vertical part, the better".  I would be stuck with
   about 15m/50ft vertical and approx. 25m/82ft
   horizontal to my shack window.

5. I have space to add another top section of almost
   any length, resulting in a "T" rather than the
   inverted "L".  Both US/VE and EU would be broadside
   to this "T" (or the horizontal part of the "L").
   Any opinions on the performance of "T" vs. "L"?
   Again, any length suggestions for that one?

6. And finally there is one thing that concerns me a lot.
   Is there an RF hazard with the inverted-L?  I can=B4t
   see the vertical leg from my shack and there is no
   way to guarantee that kids won=B4t be curious and tug
   the wire.  I would assume that if I can guarantee that
   the part of the wire that is within reach is at
   maximum current, the voltage will be minimal and
   probably harmless.  I could also insulate the wire
   and hope it holds during wet weather conditions, etc.

Now, I hope I=B4m still within the purpose of the reflectors
with this (both words TOPBAND and CONTEST are used)!
I will summarize the answers to the lists if there is

Thanks and appreciations - 73 de Kristinn, TF3KX

Subject: Any Contest Stations in Panama?
Message-ID: <19970129160006.AAA1038 at LOCALNAME>

I find I have to be in Panama City by February 23, and am planning on going
down a week early just to knock around and see what can be seen.  Looking at
the calendar, though, I realize that if I leave just a few days earlier I
can be there in time to operate the ARRL DX contest.  Does anybody know of
any friendly station owners anywhere in Panama who might be willing to
share?  Any leads would be very much appreciated.  I'll have my own rig
along, since I'm taking off /MM on the 23rd.  Even a dinky tribander already
installed would be a big leg up over a wire dangling out a hotel room
window.  Is there maybe a MARS station down there I could wiggle into?

Thanks in advance for any info.

Bruce, N6NT
