A few comments and replies. ....
Keep in mind that "kickers" are illegal for use on the CB band. Maximun wattage allowed is 4watts AM and 12 watts PEP on SSB.I have a CB in my vehicle. It has it's benefits in several ways. Even with the 100 watt kicker, range is limited but still useful.
The bands open up regularly. Ten meters had had some great openings lately. OF course, CB is meant for local comms and is not supposed to get you very far down the road. Not much better than line of sight.I have had Cbs for over 40 years, but currently have none, I think with the peak of the sun spots and solar flares they are almost useless right now. These flares run in 11 year cycles and right now is the worst.
Have you been on the repeaters lately. I don'tknow of any repeaters in the BR area which still have phone patches. The clubs all removed them after cellphones became popular. Not enough use to justify the phone bill for the hookup. I'm not even sure the SELARC club has any repeaters still hooked to a phonepatch.Many repeaters have phone patches that allow telephone calls to be made from your mobile or HT. It's handy for calling 911.
CB isn't for DX. FCC rules limit it to 151 miles max. Anything over that and you are violating. CB is meant for local comms only. If you want to go C2C or international, get your ham ticket.I enjoy the CB and when skip is rolling I can talk from coast to coast but being able to get out of country would be nice.
Could the high SWRs have something to do with the "tweaks" that someone made to your radio? CBs come pretty much ready to go out of the box. There is little to gain by "tweaking" them except the possibility of screwing something up inside.I am not running a stock radio and still have some tweaks to make. For some reason I can not seam to get my SWR down to a reasonable level and am concerned about damage to rig.
480Volts for CB? You realize that just about all CB radios run on 12 volts and probably won't pull more than 5 amps right? Even the ones with built in power supplies for desk use are going to plug into a regular 120volt outlet and work as reccommended. It's a CB radio. Not an arc welder.I love my cb, just wish I could get the power company to put a 480v service in my house !
What kind of disaster are you expecting where the government falls and the FCC magically vanishes? Comet impact? Buying the gear without knowing how to use it and practicing with it regularly will do you little good in a disaster. It's like the people who buy any other survival gear and think that when the time comes they will somehow know what to do with it. Get your ticket and upgrades. Get the gear and USE IT. Get involved with your local clubs and public service agencies BEFORE shtf so they know you and you know them. Quit dreaming of a time when the FCC/FEMA/Highway Patrol disappear and everyone is riding around sporting mowhawks and wearing assless chaps. Ani't gonna happen and if it does you won't be playing radio.But if all you can do is get the tech license, it's good. Buy the equipment for all the bands. A multi band mobile set up would be great. If shtf, the FCC will not be around. And if you already know the protocol and have a callsign that people can recognize, better chance people may talk with you after SHTF.
Being active with your local clubs and fellow hams helps too. When a peice of gear comes up for sale you are on the email list that is used to announce the sale or you get a call from someone telling you to check into it. Thats how I got my Yaesu FT-100D HF radio. A local ham knew the club was about to sell it and heard me on the radio and told me to contact the club and make an offer for it. My power supply came from another club member who had it in his truck at a club meeting. I offered to buy it if he would follow me home after the meeting so I could get the cash for him. My Amateur Television transmitter was GIVEN to me by a ham who wasn't using it anymore. So was the Yagi antenna I use with it. I was just offered the use of a packet interface this week while having breakfast with several hams in Baton Rouge. This is a regular, weekly breakfast meetup we have and a good way to find out what everyone is using and get in on any deals. I've seen plenty of For Sale items listed in club newsletters. Pay your dues. Go to the meetings. Participate in the events and GET ON THE AIR. You will meet lots of interesting people and learn that there's more to the hobby than the PTT button on the side of an HT....like mentioned there are lots of gear out there that is fairly inexpensive. Go to QTH.com or even e-bay. Sometimes you can find good deals on Craigslist too.
