- 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

- 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

- 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.

- 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

-
- 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).

- 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.
