OK, so I have borrowed a CB rig that definitely worked in and around the year of 1991.
Is it still potentially useful today or has the CB world moved on to new frequencies or gone digital etc...?
Everything is exactly as it was in 1991 - the aerial is the same length and all of it is in great condition. It has 40 channels a power/volume dial and presumably a squelch dial (makes the static noise go away and come back!).
I have moved the aerial around my house to get the best signal. When listening the meter reads 1.5 power, 5 signal. When transmitting (with the switch on the back set to "LO") the meter shifts up to 3.5 power, 8 signal.
Presumably, "power" is for transmitting and "signal" is for receiving. If so, my signal is 5 and my transmitting power is 3.5.
So... what is my range and if someone transmits with a modern CB within my range, will I have a hope in hell of hearing it? I'm listening on channel 19, of course, and no - there isn't a scan function!
