- EME2 - Simple EME Link Budget Calculator
-
-
- I've found that the old EME.BAS eme link budget calculator found on some
- of the ham-related BBS's either doesn't work right or I haven't been able to
- figure out how to use it. In this program, I've simply computerized the link
- budget calculation method outlined in the 1991 ARRL Handbook. This program
- requires input for eight of the nine following variables:
-
- Transmit Station Power (watts)
- Transmit Feedline Loss (db)
- Transmit Antenna Gain (dbi)
- Path Loss (251.5 db to 253.5 db)
- Receive Antenna Gain (dbi)
- Receive Feedline Loss (db)
- Receiver Noise Figure (db)
- Receiver Bandwidth (Hz)
- Signal to Noise Ratio (db)
-
- Plug in known values for eight of the variables, -1 for the unknown variable
- and the program calculates the actual value of the unknown. Please - only
- one unknown per run! Try this program for estimating the effect of changes
- on your EME system. If you can achieve 0 db Signal to Noise Ratio, by all
- means have at it!! I've managed to work KB8RQ with 150 watts to a 15.0 dbi
- 3.0 wavelength yagi and a 0.5 db noise figure receiver. I make no guarantees
- as to the accuracy of results given by this program, but believe it to be
- reasonably useful for estimating EME capabilities. I you want the source code
