- COMB6 - USER MANUAL
- -------------------
-
-
-
- When you run the program, you'll be asked for link parameters; in particular,
- COMB6 will ask:
-
- TRANSMITTER NAME: <The name of the Transmitter Site, only for your information>
- RECEIVER NAME: < " " " Receiving Site " " " " >
-
- ENTER TX LATITUDE, IN DEGREES.MINUTES (N +, S -)
- <You must enter the geographical latitude of the TRANSMITTER; for the
- northern emisphere, the sign is positive; for the southern emisphere, the
- sign is negative>
- ENTER TX LONGITUDE,IN DEGREES.MINUTES (W +, E -)
- <You must enter the geographical longitude of the TRANSMITTER; longitudes
- west of Greenwich (UK) have a positive sign (e.g. Usa); east of Greenwich
- the sign if negative (e.g. USSR)>
-
- ENTER RX LATITUDE, IN DEGREES.MINUTES (N +, S -)
- <You must enter the geographical latitude of the RECEIVER; for the
- northern emisphere, the sign is positive; for the southern emisphere, the
- sign is negative>
- ENTER RX LONGITUDE,IN DEGREES.MINUTES (W +, E -)
- <You must enter the geographical longitude of the RECEIVER; longitudes
- west of Greenwich (UK) have a positive sign (e.g. Usa); east of Greenwich
- the sign if negative (e.g. USSR)>
-
-
- After this, COMB6 will calculate and display on the screen the DISTANCE between
- transmitter and receiver and the BEARING (angle from the North) with respect to
- the TRANSMITTER.
- Afterwards you'll be asked for:
-
- ENTER MONTH (1-12): <This is the month you want the predictions for>
- ENTER SUNSPOT NUMBER: <The mean montly sunspot number, CRITIC for predictions>
-
- COMB6 will evaluate the lowest order F-Layer mode (the minimum number of
- "jumps" on the F-Layer requested to connect the two sites) and the angle of
- elevation (from the horizont) for the transmitting and receiving antennas.
- After, it will ask:
-
- TRANSMITTER POWER IN KW : <The power of the transmitter, in Kw >
-
- The unabsorbed field strenght at the receiving site will then be displayed;
- this is the theoretical maximum signal you'll experience at your site, in the
- hypothesis there is no attenuation from the E and D layers.
-
- To go on with calculations, you'll have to type C (& Return) and then you
- can choose if you want to:
-
- ENTER UNIVERSAL TIME IN HOURS <Prediction for a sigle hour of day>
- FOR EVERY EVEN HOUR TYPE 25 <Predictions for all even hours: 0, 2, 4, etc.)
- FOR EVERY ODD HOUR TYPE 26 <Predictions for all odd hours 1, 3, 5, etc.)
- To EXIT TYPE 27 <Quit COMB6 and return to BASIC>
-
-
- Please note: you'll NOT be asked for frequency, since COMB6 makes predictions
- for ALL broadcasting bands, from 75 up to 11 Meters Band. You can easily
- modify this, anyway.
-
- ---- END OF HANDBOOK ---
-
- Note: COMB6.EXE uses NO graphics, so no matter what kind of display you have.
- You MUST HAVE A PRINTER, since the propagation predictions are routed to it.
