We have made a minor error when we "improved" our new mail information
server. When we installed DESQview so we could have our net software
running more easily along with a very busy mail server program, we did not
allocate enough memory in one of the windows to be able to call the
mailer program to actually mail the responses. For about an hour and
a half, all outgoing mail from our server machine was tossed into the 
bit bucket. If you sent a request and did not receive an answer, please
accept my apology and re-send. Besides, I just added a whole bunch of
new files (something that will happen a lot over the next two weeks or
so), so you will get even more for your troubles.

One other "error" was noted -- our server program calls DOS to actually
send the mail. DOS recognizes = as a parse character and truncates any
addresses that contain an equal sign. We are working on a fix, but if
you have an = in your address, contact ehare@arrl.org and I can put
you in our server's alias file so you will get a response -- a band-aid,
but it works. :-).

Please report any additional errors, or comments, suggestions, praise or
gripes to ehare@arrl.org.

If anyone missed our posting on this new mail-server service, send email

The vote was strongly against auto-cancelling those two users.

It would have been interesting if I'd gotten a majority vote to cancel
them: with a majority vote I probably could have gotten away with it, and
it would have changed Usenet policy. We still need some kind of

A differential-mode AC-line filter, commonly called a "brute-force" AC-line
filter will probably take care of the problem. You may want to experiment
with its placement, trying it at the radio and/or at the dimmer.

It may also be necessary to add a common-mode choke, made with about 10-20
turns of the AC-line cord or AC wiring (the house wiring should only be
modified by a licensed electrician) wound on an FT-240. 73-, 75-, 77-, J-
or 43-type cores will probably all work.

Here is some information from the ARRL RFI Tips package. A paper copy
of the entire package is available for an 8X12 SASE and 98 cents postage

Organization: University Of Kentucky, Dept. of Math Sciences

I am just getting started and am very quickly appreciating the tower that was  
installed 20 years ago for televsion use.  However now I would like to put up  
a 144/440Mhz vertical antenna and was wondering if I should take down the old  
UHF yagi that is up there now and put the vertical on top of the tower, or if  
I should leave the yagi up there and attach the vertical to the side of the  
tower.

If the yagi could ever be used for anything then I guess I will leave it up  
there.  I guess my question is what uses do UHF television yagis have?

Thanks for all your help!

Most of the "quality" and accuracy calculations I have seen with respect
to GPS concern the number of satellites in view and their orientation
relative to the observer.  The same calculations are made (and displayed)
with "spoofing" enabled or disabled.

Mike (and all others)...

Censorship is when one person forbids another to express certain opinions.
Filtering net-traffic doesn't forbid them any expression, rather it simply
selects which material the station-owner is willing to foot the bill for!
                           ^^^^^^^^^^^^^
Freedom of Speach does *not* apply to the filtering of amateur net-traffic,
since no one's *RIGHTS* are being infringed upon...  You can still *say*
whatever you like (on your own time, with your own transmitter, paying for
it out of your own wallet).  The re-transmission of net-traffic however,
payed for by private citizens, is a *PRIVELIDGE* granted at the discretion
of the one(s) bearing the *cost* of it.

IT IS   * N E V E R *   YOUR "RIGHT" TO SPEND *OTHER* PEOPLE'S MONEY!!!

Hi,

I have an ICOM IC P2AT 2 metre Handheld.

I can enter frequencies from 0 to 1310.

I can only transmit between 144 and 148, thats Ok
BUT when it comes to receive I have a problem.

I can go as high as 161 and as low as 118.
hen I go down to the Airways freqs it changes to AM.

Does this model receive above 161 or below 118 ?

I cant see the point of scanning between 0 and 1310 if
it wont receive these. There must be something wrong.

Checking specific gravity is probably the easiest if you have lead-acid cells
or open nicads.  Otherwise the test is to discharge them and plot the curve.

Trimble navigation (San Jose, CA area) has a better unit.  Unlike the
Sony unit, the GPSS antenna is part of the case making it more of a true
portable.  This is the unit (or perhaps a miltary version) which was used
in the Gulf War.  It is about the same price as the Sony Unit. I have
seen it mail order from a least one place, you could also call Trimble and
ask them where to get it.

If the filters are designed to have a high output impedance out of band 
you can just tie the outputs together and not suffer an extra 3dB loss 
from a combiner.

The high pass needs about 60 db of isolation for Channel 3 to get a really 
good picture.  The low pass didn't need to be so good in my case as the
output of the cable box only went up about a 1 1/2 channels.  Both
filters were around 7 pole jobs.

I did the above when my cable company have trash channels below ch 13 and
I didn't really care if I needed the Cable box to get them.  It worked fine.
Now if I can only find the schematic.  I built the thing years ago.

Last year I had an address for a Telnet site that would give out information
on a person by callsign.  Howeever, I have misplaced the address and need
it again.  Please E-Mail me with the info...

   I'm looking for HAMS working with 10Gig gunnplexers in the Bay Area.
If any one know of someone that could help a newcomer to the technology,
please drop me email.

                       Thanks...

Interesting exercise.  Since the OD of the pin on a male UHF connector
runs around .15 inches, I doubt you could get much less than .2 inches
OD on the center conductor of a female connector.  In other words, it
is impossible to make a 50-ohm male-female connection with UHF 
connectors using common dielectric materials.  (Although air might work.)

Of course, below UHF frequencies, the length of the non-50-ohm section
is so small (compared to a wavelength) that the mismatch is insignificant
(as I showed in a previous posting).
