On the VHF/UHF bands depending on your area there are a fair number of people on the radio.There is a good number of repeaters in my area and some of them are pretty busy,others are pretty quiet depending on the time of the day.
There are the regular people that get on a certain frequency or repeater and chat away the day,some are morning people and some are evening people
HF bands I find people pretty well 24/7 depending on the time of the day and the band,since some bands are active during the day and some are active at night...this is where I spend most of my time when on the radio. There are a few people that I hear on a regular basis when the bands are open and do talk to them when mother nature allows me to make the contact
For me personally I made the choice to go to ham radio because I was seeing CB starting to lean towards people using poor operating practices ...ie: misstuned radio or running insane amounts of power, cussing,interfering with others conversations,noise toys,just to mention a few.....Now I do still find people on the ham radio bands that will chew out a person for whatever reason, cause interference ,but on the bands I run this does not happen very often .....so for me the choice was easy...personally I run a very basic station at home,a 2 meter radio ( 75 watts of power,and a groundplane antenna) and my HF radio( 100 watts of power with a basic dipole antenna ) and I make plenty of contacts...and have met some great people on the air ,not to mention just simply have alot of fun trying to make contacts all over the world or around my general area
I will say there are good and bad operators in both CB and ham radio, but for me personally I found ham radio to be more fun and I have alot more things that I can get into as far as types of comms to do,amateur TV,digital modes,bouncing a signal off the moon..aka moon bounce... just to name a few...I have even made a couple of contacts to the international space station...
As I said in the other thread you have going take your time and do your homework.....
...oh yea,you have found a good place to ask all the questions you can come up with.the people here have a wealth of information they are more than happy to share that is based on their personal experiences ...not alot of hype....what you might find out may not be what you want to hear but it is what you will need to hear for the subject in question...
and once again welcome to the board !!
