you do not "set" swr.you cannot set it on the radio. the radio can tell you what yourswr is. it can take an swr measurement. swr has to do with the antenna system. in order for the radio waves to radiate from the antenna properly, the physical length of the antenna must match the length of the radio waves. if the antenna is too long or too short you will have a higher swr ratio. the higher the ratio the less energy will leave the antenna. but that energy needs to go somewhere, so it goes back into the radio which causes damage and can ruin a radio.
first turn the channel to 20. then switch the meter switch to CAL. then key the radio. while keyed, turn the CAL knob up until the needle in the meter gets right to the CAL Mark. next flip the meter switch and key the radio. where ever he needle is, is what your swr is.if it is more the 1.5 that's getting high. if its over 2 you are in the danger zone. if its over 3 you are damaging your radio. you must repeat the calibration proceedure for every channel.to figure out weather your antenna is too long or short, you compare the swr readings from channel 1 and ch 40. if the swr is higher in 1 then on 40 the entenna is too short. if its higher on 40 then 1 its to long.
You appear to be aware of you antenna system with the separate meter attached so the tells me you dont punish a radio with an high swr. I am just guessing red wire/solder in mic cord at plug given that it is a side mic mic jack.
Stock mic 1- Shield (Ground) 2- Yellow (Audio) 3- Red (Transmit) 4- White (Receive)
S.W.R == Standing Wave Ratio, this is a Relative measurement of the Amount of Power Going UP the Antenna, Versus the Amount of power being "Reflected" Down, the Antenna. This ratio, is displayed, as a reading on the meter. Also Often this SWR meter is dual used as an "S" Meter, this is used ti display relative signal levels from other transmitters. and is shown, as an "S" Scale. 0 - 9 on the meter.
I'd start by checking the easy things.
1)Try a better meter
2) If your Standing Waves are high, that could be the cause.
If they are good (<1.5:1) continue to 2)
2) Try another microphone.if the second mic is just as bad it could be the alignment is off.
3) Perhaps the bias adjustment to both finals and the driver are wrong. People do go in and turn them sometimes :-(
4) Maybe the output finals are soft.
You can probably change the transistors yourself as long as you have good soldering skills, eyesight, a steady hand, the correct tools, some heat sink compound, and the ability to correctly retune the output stage.
If not, pay someone to do it correctly. You don't want to end up with an anchor (and not a very good one at that).
Well,some meters are set different than others,to see what is going on,you need a good WATT-SWR meter,but that is not a bad reading of SWR, you can get one at Radio Shack. You can not go by the meter that is on the radio,it,s probably not set right. hope this helps..
check it with an external meter to verify. if showing different.cb shop temple, tx on yahoo search. would take it to a shop to have the swr board redone. or could just be a simple pot.. even from factory they have problems.
THAT IS A VERY GOOD SIGN THAT YOUR SWR MATCH IS
OFF....I DONT KNOW IF YOU MATCHED UP YOUR RADIO WITH YOUR ANT.IF NOT
YOU CAN BUY A CHEAP SWR METER @ RADIO SHACK...CHECK THAT YOUR COAX
CABLE IS OK TRY TO REPLACE THE COAX......GOOD LUCK
