Use your D7 to find each other at Dayton, anytime, anywhere, including indoor. No GPS dongle needed.
The D7 and APRS is not just GPS! The only people who need GPS are those that are lost or moving. Use your D7. Put something useful in it. It can hold three posits as is, and it only takes a tweak of 2 digits to put yourself anywhere within the HAMvention complex or Dayton area...
Just take a note card with your favorite locations in and around Dayton where you will be hanging out and manually enter your posit when you sit down for a while. Your favorite bar, restaurant, motel, meeting, etc. Here are some examples on the grounds of the Hamvention:
Basic HARA posit is 3949.yyN and 08415.xxW Then tweak the X and Y digits whenever you hang out in one of these rooms. This list proceeds diagonally from the front Traffic light to the extreme NW corner of the Hamvention fleamarket/parking area. In fact, cut this out and tape on the back of your HT:
3949.yyN/08415.xxW yy/xx Location ----- ---------- 19,24 Traffic light 23,28 East Hall 23,33 Ballarena 26,33 Food court 26,37 Forum rooms 27,32 North Hall 29,38 Arena 36,62 Extreme NW corner of the Flea Market/parking lot area 3946.87N/8406.60W TAPR/AMSAT meeting at AF museum
Anywhere in between is trival to estimate using the above figures assuming you have even a basic sense of direction.. Each hundredths digit is 60 feet.
Trying to find someone? Just enter your estimated posit above, and then your D7 will show you the distance and range to them (if they are updating). Don't just leave some stupid old posit in your D7 that has nothing to do with reality.
If nothing else, enter 3949.2-N and 08415.3-W and set position ambiguity to 1 digit, and this will show the world that you are basically inside the building complex.
See ya there. On the road enroute Thursday afternoon.
