First off - no legal CB radio produces more then 5 watts AM and 12 watts Peak Envelope Power ( PEP ).. Note I said 5 watts - back in the day of tubes, a brand new transceiver with brand new tubes would put out about 5 watts AM for maybe a couple of hours until the tubes broke in. Once the tubes settled, about the best you could do - minus the peak n tune was about 4 watts. Allowing a power factor - loss - this produced about a maximum of about 3 watts AM with mismatched components - since you wouldn't throw away all the tubes when one tube became weak or died. Even with 3 watts and a VSWR of 1:1 - with a piece of coax 60' long to a beam antenna, you would have to deduct what the loss rate was of the coax before multiplying what ever the gain factor was of the beam antenna. Hence you couldn't stick 3 watts in one end and have 3 watts come out the other end. If PEP is 4 times the carrier, there is no way that you could get 10 watts AM and only 20 watts on SSB.... If it put out 10 AM it might show as much as 40 PEP on SSB depending upon the mode... The carrier is a power hog, robs the transceiver of almost 60% of the produced power. That leaves 40% to be divided between the two side bands. 60% of 10 = 6 40% of 10 = 4 Half of that would equal 2 4+2 = 6 watts minus the carrier.. Or a 50% increase in transmit power...

There is nothing special about a cheap CB radio.. It is only worth what the market will support. It doesn't do anything especially well... A old tube type Johnson Viking Valient will do about 275 watts AM on 11 meters and a thrifty person could probably find one at an estate sale for less then $500.00 A new Kenwood TS 2000 will do 25 watts AM or 100 watts SSB on 11 meters all day long.. Most any amateur radio equipment can be modified to operate on 11 meters - ( CB ) so why waste money on a cheap CB radio piece of crap... The only reason why someone says that it is worth anything is because they do not know any better... A CB radio lacks proper filtering to take away most of the AM noise that most people who deals with the cb radio AM crap has to put up with... A Kenwood TS 590S - is a little overkill at $1800 new, but would run circles around most anything ever made for 11 meters only!

I think *you* miss the point, Channel Jumper.
First, the Uniden HR2600 is NOT a "cheap CB radio"; it's a 10 metre amateur radio. Second, the original ad was placed in 2004, so it is most likely NOT available today. Stop pontificating and read more carefully, CJ. Quote:

The original post (offering the HR2600 for sale) was dated May 2004! That's 8 years ago, not 4. Geesh!!
Please stop pontificating and pay attention! |
