PropNetPSK Frequently Asked Questions
What is a Grid
Square and how do I find mine? Each sub-square is designated by the addition of two
letters after the grid square, as FN44IG. These more precise locators
are used as part of the exchange in the 10-GHz contest. They measure 2.5 minutes
latitude by 5 minutes longitude, roughly corresponding to 3 × 4 miles in the
continental US. PropNetPSK requires the 6 character
grid square.
A Grid
Square is an instrument of the Maidenhead Locator System (named
after the town outside London where it was first conceived by a meeting of
European VHF managers in 1980), a grid square measures 1° latitude by 2°
longitude and measures approximately 70 × 100 miles in the continental US. A
grid square is indicated by two letters (the field) and two numbers (the
square), as in FN31, the grid square within which W1AW, ARRL's
Maxim Memorial Station, resides.
There are a number of ways to find
your specific grid square. If you know your exact latitude and
longitude, you can compute the grid square directly in the program by double
clicking on the entry box. A new window will appear and allow you to enter
your latitude and longitude and return you grid square. If you do not know
you latitude and longitude, there are a couple of things you can try. If
you are close to an airport, go to AirNav, type in the airport name and
you can get a latitude and longitude for there. Enter you callsign at QRZ or Buckmaster and the extended information
may reveal a usable latitude/longitude or even a grid square that is
accurate.
What is a PHG code and how do I compute
mine?
This code is basically
an APRS Data
Extension specifying Power, Effective Antenna Height/Gain/Directivity. For
Propnet we have added a couple of additional fields to this code for our
use. To compute this, double click the entry field and a pop-up calculator
will appear. Fill in the requisite information and your code will be
computed. Since this is a variable length code, it MUST end
with the slash character ( / ). If you are a Short Wave Listener or
just a lurker, then you must enter a 0 for the power and a 0 for the TX
interval.
Why do I get this message about an
external API socket error with a error code similar to
100049
API socket error messages can be very
difficult to troubleshoot. Basically these message indicate there was a
problem with the internet connection, either during the connection to a server
or during the attempted transmission of data to a server. There are a
number of safeguard in the software to catch a number of these, but occasionally
one may appear. First thing to do is make sure you have a solid connection
between the computer and your internet gateway. Try checking your email or
bring up a web page. If these do not work, then the problem is between you and
the ISP. Check the cabling between the computer and the router or
modem. Make sure the router has not locked up. Check your modem for
proper operation. If these appear to be good, try to establish a telnet
connection to Livex.rochesterny.org:2032. If this fails, then either the server
is down or there is a problem between your ISP and the server and you can do
nothing until that problem has been eliminated. If you have a firewall
installed, then you will need to make sure the firewall will allow TCP packets
on port 8911. Please refer to your firewall's operations
manual.
After I configure
everything under the tabs on Program Setup I get a time error. It says '6::PM'
is not a valid time.
This usually
happens when the computers time is not properly set to display 24 hour
time. Windows normaly defautls to the AM/PM convention. You can change
this under the Regional Settings in Comtrol Panel. You should set the time
to display as HH:nn:ss and this will elimiante the AM/PM indicator and allow the
comptuer to display time in the 24 hour
format.
