Good night Gary.

3db, 6db etc refers to the aerials gain, which basically means it's transmit/recieve pattern. See the image below, it explains it a lot better than I can.

40 channel UHF radios have their channels evenly spaced within a certain frequency range. The newer 80 channel units operate within the same frequency range but have the extra 40 channels in between the original 40 channels, I hope that makes sense.
As a user it means you have a much better chance of finding a clear channel.

Just to confuse you even more, on the current 40 channel UHF band channels 1 - 8 are repeater channels, so you only use these when you want to access a repeater. A repeater is a base station that picks up your signal, amplifies it and retransmits it to increase the range of transmission. BUT, when you use a repeater you utilize the duplex feature on your UHF, where it automatically transmits on say channel 1, but recieves on channel 31. 2 & 32, 3 & 33 etc. So you should NEVER choose channels 30 - 38 for general transmission.
So now your 40 channel UHF only actually has 24 general transmission (or simplex) channels. Of those 24 channels building sites, trucking companies, traffic controllers etc all have their chosen channels and it starts to get a bit crowded. The benefits of an extra 40 channels is obvious. The second pic should help explain how duplex and repeaters work. If you click on the attached thumbnails it will enlarge them.

Have I thoroughly confused you yet?

Welcome Gary from the apparent oldest member (although some might not be telling their Age).
Have not taken up Lawn Bowls yet as I believe it is a dangerous Sport. Something to do with having the highest death rate whilst participating. LOL
All jokes aside congrats on your intro and enjoy

Iknew what it did, but not having my set in front of me I couldn't instantly recall Duplex/simplex as I hardly use it anymore.
Nice discussion and I have saved your attachments too.You're a natural at explaining this easily. I know this stuff and still couldn't say it as well as you. (but I didn't know out on 1 in on 30 stuff)
