I just purchased a power supply from ebay. The item was a: Radio Shack Regulated 3 amp / 13.8 VDC Power Supply (model 22-504)
Just wanting to get some feedback on this. Did I get a good deal? Should it be enough for my needs with my cb radio? I paid 18.00 dollars for it and priced a new one with radio shack for 41 dollars. Just a side question about this.
I know this will help my TX alot but will it also help my reception of other radios.
Thanks. |

Cnmcake,
A 3 amp power supply will be good for most Stock AM CB Radios.
You may want to check out my Article for more helpful advice on what size you need for different radios and uses.

Cnmcake,
That'll at least allow the radio to tx now, but your TX/RX is still going to still be a bit of a disappointment to you if you are still using the mobile antenna you mentioned before. It will work for local talking ok though. A constructed or purchased dipole would probably perform better and if you are on a tight budget (with todays gas prices who isn't) is a good choice. You can build one just as easy and less expensive than buying one. Just a suggestion. I built one with some coax I salvaged from a surplus warehouse of ours and was pretty pleased with the results, and I had it mounted at ground level and in a vertical positon and could still talk about 30 miles out to one station. I never did put that antenna to any kind of height though and have been thinking about taking it down and remounting it on the house in a inverted V configuration. I might add, it is also fun to construct and "tinker" with the different mounting configurations to see which works best for you. |

Cnmcake,
Your radio has no idea what kind of power supply you are running and the Power supply will not help on Receive as it has nothing to do with the Receive in your radio or your antenna.
If you are running too small of a power supply for a radio then Yes, it will effect your transmit power and can limit your Output signal.
Your Coax, Antenna, and Output Power of your Radio and Conditions and correct setup will determine what you hear on your radio and how far you will be able to talk.
As for a good deal? if you are happy with what you paid for it then Yes it is a good deal.

And to think I've given away several 3 amp. power supplies or scrapped them for parts over the years. |

It may help with your reception if your previous power supply wasn't filtered and produced a lot of noise. You won't really be able to tell until you use it.
It should allow you to transmit on a stock AM rig.
For folks new to CB I suggest this book:
http://www.copperelectronics.com/cgi-bin/checkitout/checkitout.cgi?catalogSTORE:CKIE:prodBKS-00020+
It'll answer most of the questions you'll ever have about CB radio, and if you read it cover to cover you'll know more than 99% of CBers. |
