Have you measured the signal strengths from a few stations of known
locations, power levels, and antenna gains, and compared them with your
program's predictions?

- this apparently simple program computes path loss in dB between
transmitter and receiver, field strength at the receiving site, and
receiver S-meter readings. Transmitter power output can be varied
between 10 KW and 1 milliwatt.

It is educational for newcomers and of assistance to DX and
line-of-sight experimenters. It illustates how S-meters OUGHT to work.

Download program PROPGATE from website below in a few seconds and run
immediately. Its at the bottom of the list.
