For either line-of-sight or multi-hop propagation through the ionosphere -
- 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.
