VISUAL DISTANCE. A rough rule of thumb is to take the square root of the height in feet and that will give the miles from the antenna to the ground.  Repeat for the other antenna and add the number of miles. This can be multiplied by about 1.2 to 1.3 for radio waves.  For example if the transmitter antenna is 625 feet high and the receiving antenna is 16 feet high,  square root of 625 = 25 miles, square root 16 = 4 miles.  Add 25+4 = 29 miles for the visual distance.  Then multiply this by 1.3 to get  37.7 miles of radio range. This gives the visual distance. And of course, transmitter power and antenna gain, receiver noise figure and antenna gain enter into it, see links above.

FROM THE INTERNET
The basic equation for path attenuation is Attn. = 36.6 + 20 log F(MHz) + 20 log d (miles) (in dB).* The log function dilutes the effect of frequency change, so tripling the frequency from 147 MHz to 441 MHz increases the loss by  20 log 3 ~ 10 dB.
* ITT Handbook, Chapter 28 in most recent editions.

Clarification from Larry W9QR:

With reference to 144 MHz and 440 etc. Path loss in free space is independent of frequency. The free space loss equation has a frequency quantity in it to offset the loss of signal received by an isotropic antenna. An isotropic antenna or a dipole for that matter intercepts 6dB less wavefront energy when the frequency is doubled. There was no increase in path loss. (In free space). Since by definition, all isotropic antennas radiate equally well at all frequencies, there is no need to "crank in" another 6dB to adjust for the transmit antenna when we double the transmit frequency. I have seen that equation referred to as Path Loss between isotropics. That describes it quite well. Most of my work is in the GHz range so I use 96.6+ 20logF (GHz) +20 LogD (Miles).    73,    Larry Wheeler

Another rule of thumb is doubling antenna elevation at VHF produces about 6 dB gain.

Simplex --http://perso.club-internet.fr/f1orl/program/simplex.zip  This software is intended to replace the hardware logic of repeaters. With SIMPLEX, repeaters may be quickly implemented with a few connections between the computer sound card and the audio receiver output and microphone transmitter input.It handles simplex repeater, duplex repeater, transponder and mixed mode. It supports classical 1750 Hz tone detection or CCTSS detection to open. It plays any audio service message (beacon, welcome, goodbye, transmit, timerout messages).It repeats communications either on audio detection (vox mode) or carrier detection (if a squelch signal is available).It detects DTMF codes for remote control.It works also as a simple parrot or voice recorder. It runs under Win95/98/NT/2000/XP.

OFFSETS AND TONES

The standard offsets for HF/VHF/UHF/SHF are:

29 MHz     100 kHz   (-)

147 MHz   600 kHz    (+)

1.2 GHz   12 MHz   (-)

50 MHz     500 kHz   (-)

222 MHz   1.6 MHz    (-)

2.4 GHz  20 MHz    (-)

145 MHz   600 kHz   (-)

440 MHz   5.0 MHz    (-) **

 

146 MHz   600 kHz   (+ or -)

900 MHz   25.0 MHz  (-)

 

** Plus Offset In Some areas - notably Northern California.

When a repeater receives below the transmit frequency it is termed a minus offset. A repeater that transmits on 147.13 MHz and receives on 147.73 has a plus offset. Repeater input frequencies are given as either + or - signs to indicate whether the user's transmit frequency is above or below the repeater transmit frequency. Repeaters that have outputs in the lower part of the 146 MHz portion are often plus offsets while those operating in the upper portion of 146 MHz are minus offsets. See your repeater guides. Most of the new rigs default to the accepted offsets.
