Hello,
Last week I have uploaded the latest version Graph Packet (GP) to ucsd.edu.
It can be used in combination with a tnc/2 or a baycom modem with tfpcx.
I will upload the latest version of tfpcx 2.1 which allows you to use multiports
and SCC cards like the PA0HZP card of the BAYCOM USCC card.
Although it is HAM-public domain software, please read the notes in the
documentation.

Hello Keith,I can probably help you out.There is a company called
communications specialist that can provide a ctcss encoder board
that is universal.Check with one of the radio shops up in your
area or the local radio club folks may be able to help.Worst case
call me and Ill see if I cant find some one to help out.Im at 602
-840-7810.The cost of the board is about $30.Good luck.

There are several companies that make what is commonly refered to as
"disguise" antennas.These are made to take the place of the regular
broadcast antenna,and when combined with a coupler,will also function
as a broadcast antenna.One of the companies is Antenna Specialist Co.
at 216-349-8400.Another,which I would reccommend,is STI-CO Industries
at 716-662-2680.Both of these companies will sell direct or send you
to a local distributor.One additional piece of info is that Barker
-Williamson use to make a tuner for your purpose.I dont know if they
are still in business.I should warn you that "disguise" antennas are
very expensive but work fairly good.I use an antenna specialist model
for 6 meters on my chevy and have had no problems.Good luck!

Well Greg it finally comes out. You obviously have some prejudices of your
own. You just did the very thing your are berating everyone else for. I
just happen to be from the south and I am offended that you mock our speech
patterns and imply that we are all just a bunch of ignorant hillbillies.
You posted the mail from the gentleman who is half-Asian and was teased as
a child for it. We moved out of the south for a period when I was growing
up and I was teased and mocked for my southern drawl and the way I talked.
The other kids imitated my southern accent just the way you are doing. I bet
it does chap your PC ass to know you are no better than those you criticize.
But you know what? It doesn't really bother me, I am just putting you on.
I really did grow up in the south and I was teased as a kid but I don't take
such things personally. I can laugh at the Beverley Hillbillies, and Green
Acres, and even the Ernest movies without feeling personally attacked. As
others have tried to point out it is the intent that is important. I seriously
doubt that there is a single participant in this thread who would condone
blatant and vicious racism or prejudice. That wasn't the intent of the person
who originally posted the article and probably wasn't the intent of the author
either but I have no way of knowing so I personally choose to give him the
benefit of the doubt.
It has gotten to the point where you can't do or say anything in this country
without offending someone for something and they're going to get in your
face about it. Lighten up! Yuh know whut ah meen, Vern?

Subject : Re: hypochondriac scared of cancer!
Here is another angle on the field strength calculation.
I think we are all converging on the same method of calculation,
but we have differences in our math for some reason.
The Problem: Calculate the power density at a point near the ground that is
100ft away from the top of a 70ft antenna tower. The antenna is outputing
3000 Watts at 104MHz.
Constants: 100ft = 30.8m = 3080cm
70ft = 21.5m = 2150cm
Zo of air = 377 Ohms
Wavelength of 104MHz = 2.88m
Assumptions:
1. The antenna is a simple vertical half dipole (l=.72m).
2. Since the distances we are dealing with are many wavelengths
away from the antenna, and the antenna is small compared
with these distances (0.72m vs 21.5m), we can assume the
radiation pattern is approx. spherical.
3. Ground wave reflections add in phase with the incident wave.
As soon as the wave travels 70ft or so we will have ground
wave reflections and standing waves.
These are definetly worst case assumptions, except for possible antenna
gain in the direction of the dorm window.
Formulas:
1. Surface area of sphere = SA = 4*pi*r^2
2. Incident wave power = PI = Power at Antenna
-----------------------
Surface Area of Sphere
(calculated at a distance r from the antenna)
3. Total power density PD = PI + PR(reflected power) = 2*PI
4. Field Strength = E = sqrt(Zo*PD)
Calculations:
1. SA = 4*3.14*3080cm^2 = 119e6 cm^2
2. PI = 3000/119e6 = 25.2uW/cm^2
3. PD = 2*25.2uW/cm^2 = 50.4uW/cm^2
4. E = sqrt(377*50.4e-6) = 138mv/cm = 13.8v/m
A power density of 50uW/cm^2 is about 20 times lower than the ANSI specified
safe power limit of 1mW/cm^2 (at 104MHz). Several things are likely to make
the actual power density lower.
1. Power actually drops of as 1/r^3 for several wavelengths around
the antenna, not the 1/r^2 that was assumed here.
2. The dorm building will probably have a metalic structure that will
tend to attenuate the power (though not nearly as much as it will
attenuate HF power).
3. Reflected power may not add to incident power it may subtract.
If there is antenna gain in the direction of the dorm, this would tend to
offset 1 and 2 above, but I would be surprised to see a field strength as
high as 13.8v/m in the dorm room.
If the origional poster is still concerned, you may be able to borrow a
field strength meter from your campus Engineering dept, or from the nearby
radio station (if you state why you want to borrow it). You would have to be
at 61.4v/m to be at the ANSI limit of 1mW/cm^2.
Cheers,
Eric
