When I get to a tight spot where I need the overhead clearance (eg. a

Subject: Grid Squares & Lat/Long
To: info-hams@ucsd.edu
Hello!
I recently borrowed a GPS device to calculate my Latitude & Longitude. I
found a couple of basic programs on Compuserve to calculate my grid square
from this info. Either something is wrong with the program, or something is
wrong with the ARRL map in one of their books. Here is my lat/long:
Lattitude: 39' 39.303 N
Longatude: 89' 10.550 W
When I feed these numbers into the programs, I get EM59JP. When I look on the
map, EM59 is in Illinois and I live in Indianapolis, IN. Is the map wrong, or
is the basic program wrong?
Thanks
Jay

Absolutely you bet! If you've ever seen a tree struck, you know that
it can explode from the rapid formation of steam in the trunk. The
ground can explode as well, but it's less likely. The volume intimately
connected to the rod is rather large, so the heating is spread out over
a greater volume, and thus generates lower point pressures.

Remember that you can get something in the Congressional Record just by
convincing a congressman to read it. And we know about their record for
veracity, don't we?
I suspect (no documentation, but then neither has anybody else :-)...) that
the term far predates radio, and may have something to do with ham-fisted
telegraph operators.

I didn't mean that the Congressman would read the origin of the word HAM into
the record, but whatever he =did= read into the record would contain vocabulary
that would illuminate the question.

I'm resending this message as I neglected to give my email address:
HELP...
Any Extra Class hams out there who can help me complete some endorsements
for the 75M WAS (aka GERATOL) net? Out of over two dozen various endorsements
available, I have whittled my list down to only a state or two for certain
ones; that is, if I can work stations having the call sign formats following
for the states listed, I can finish off these endorsements. The call sign
formats and states needed are:
Callsign #
Format Example Needed States
N 1x2 N2KK (2) AR, WV
A 2x1 AB3C (2) HI, ND
K 2x1 KC8X (1) WV
W 2x1 WA4X (3) AL, ID, UT
If any of you Extras out there having a call sign with the above format
and state can schedule a quick contact with me (shouldn't take any more then
a minute or so) in the 75M Extra Subband before it gets too noisy, pls send
an email reply direct to me, and we'll work something out. Thanks in advance
to anyone out there who can help me out!

Call the FCC at 717-337-1212. This is an automated information service which
gives all the latest (as of first of month) info on all processing. It also
gives the calls issued in each class as of the first of each month. Just
listen to the announcements and press buttons accordingly. It recently
changed, so I don't remember the sequence - I have the old one,but it is now
different. One option tells you what the turnaround time is and if you back
up, another will tell you what calls are issued.
In 9land, as of March 1, it is AA9KI for Extra, KF9UM for Advanced, N9WHC
for Tech/General, and KB9IXF for Novice. Turnaround was reported as being
10-12 weeks.
I have not seen any postings recently on turnaround actual time. A few months
ago, there were many notes on here giving actual times. Some were much sooner
than reported by the FCC. I guess they were being conservative in the
recorded message.

This is not strictly correct; SSL are the company who are contracted to

If it is anything like a standard Navy buoy, it broadcasts VHF-FM on one
of 99 channels, ranging in frequency from 136.00 - 173.5 MHz.
If you can supply the channel number (it might be printed on the buoy, or
selectable by a little switch on it), I can give you the frequency.
Hope this helps,

There was a feature article on this in one of the Ham magazines, I think
it was _Ham Radio_. The US government uses meteor scatter to gather information
on snow pack thickness in the Rockies for hydrological forecasting. I don't
recall whether it was the Corps of Engineers, NOAA, or some other branch
of government doing it. But I do recall that they were using frequencies
near 6 meters, 100 watts, and 3 element yagis to connect the reporting
stations to receivers in Washington. Meteor scatter has also been used
in Alaska to relay communications between villages, and has also been
the basis of some military communications systems.
We're talking about the constant rain of micrometeoroids here, not the
big visible ones. Individual "pings" are short, but there's a constant
source of them. Hams who work meteor scatter tend to wait for the big
meteor storms and use the longer, and rarer, pings off the larger trails,
but that's not necessary. Only if you use analog voice or hand keyed
Morse are the longer pings needed. If you use digital burst communications,
and good FEC, you can take advantage of the constant supply of short pings
available from micrometeoriods.

QST had a couple of articles in the 80's and 90's - I don't have exact
references which provide some basic info.
There have been sessions on Meteor Burst Communications (MBC) at the last
few IEEE Military Communications Conferences with a number of papers.
There have been several papers on MBC published in IEEE Transactions on
Communications Theory and AGU Radio Science over the last few years which
get more theoretical.
There is a new book out, edited by Schilling, entitled Meteor Burst
Communications: Theory and Practice, John Wiley & Sons publisher, ISBN
0-471-52212-0
And finally, a list of recent references is in:
Ralston, W. T., 1993, Application of spread-spectrum multiple access to
high-density fixed and mobile meteor-burst communications networks,
doctoral
dissertation, University of Massachusetts Lowell.
which may be ordered from University Microfilms Inc. (check with your
library, they probably have ordering info).

Subject: YAESU FT101 TUNING
To: info-hams@ucsd.edu
Can anyone help me? I've recently acquired a Yaesu Ft101E xcvr
and sometimes have difficulty zero-beating another station. Tuning
to voice pitch on sideband gives me varying degrees of accuracy,
and sometimes causes me to be 1-2 Khz low. This happens more often
on 80 M than on 20, and usually with weaker stations when I can't
use the S-meter as a tuning indicator. This is an older, analog-tuning
radio and I'm sure the new rigs are so selective that sometimes
a kHz or two makes the difference...but it's all I've got! Any
advice to my Email address would be much appreciated.
