How can I tell if My Find Works AM/LSB/USB

[SD002]

I've got a Pace SideTalk 1000B 23 channel just like the one pictured.... Still works too........ What you need to do is read up some on antenna basics. You can find this information on the net.. Each frequency needs an antenna or wire if that's what you're using to be a certain length in order to receive or to transmit the magnetic wave to the best of it's ability so to speak. Otherwise the wave doesn't go off the antenna like it should and it is reflected back to the CB which will heat up transistors beyond what they can handle causing them to burn out. Different frequencies are grouped into bands. The CB band is refered to as the 11 meter band and ranges from channel 1 or (26.965 MHZ) to channel 40 (27.405 MHZ). Antennas made for the CB should be at a length that will give you the lowest SWR reading across all of these channels with channel 20 probably being the lowest. SWR is the measurment used to see how much of the wave is coming back instead of going out through your antenna. The higher the MHZ the shorter the antenna will need to be.. The lower the MHZ the longer the antenna needs to be. For a CB antenna a 1/4" difference in length either shorter or longer will make a big difference in the SWR readings. So in answer to your question about running a Short Wave receiver, a CB, and a scanner into one antenna. You can, but you will not receive as good as you could if you used the proper antenna for the scanner and the proper antenna for the short wave receiver. You can get the proper adapter fittings at Radio Shack to fit the scanner to the CB antenna.. It's probably a BCN to a PL 259 adapter that you'll need..... Most Importantly... Never transmit on the CB if anything else is plugged into the same antenna at the same time or you'll have a big puff of smoke or in your case 3 big puffs of smoke if you have everything hooked up at once... CB's need to have the proper antenna if you're going to transmit on them.. You can make an antenna that will work for your CB if you study the antenna basics for a CB.. It's not all that difficult once you understand what's happening and can follow directions to the letter. You will also need an SWR meter (if your radio does not have one but your Pace does) to adjust the antenna to lowest SWR readings. Remember the lower you can set the SWR's the stronger your signal will be resulting in reaching out a greater distance when you transmit.... Good Luck
