newby cb install issues

[stealth]

i have installed a cb radio myself and cannot srnd or receieve. pretty sure i have missed a step somewhere...any ideas where to start.like maye a critical earth point?

did you tune it? (assuming it is 26mhz not 477mhz)

[bob_or_jim]

Did you turn it on without the aerial plugged in? If so you may have burnt it out. Without knowing what model it is its hard to tell. Is it brand new?

Im assuming CB has power and the display is tuning. if so then aerial might have a short, check the aerail has no shorts, meaning when the aerial cable is removed from the CB, the centre wire to the antenna is not shorted to the outer, need to check with mulitmeter on ohms test. should be 0 ohms/ no circuit inner to outer.

easy to occur to short the inner to the outer with a bit of the outer braid wire touching the inter single wire at aerail or CB connection if you have striped and made these yourself

Then check aerial has circuit to aerial base both centre and outer sheild .

Unit is uniden uh-012. and it was powered up prior to installing the areial .i will get the multimeter out after work. the whole install seemed peetty straight foward. altho was not aware i had to tune it..might have to do a bit of research.

background story: got unit from my mate with no areial, truck cracked head so it sat in my shed for a year...fixed truck so i went and got arieal, cable and bracket for xmas pressie lol. (brand new not scratchbuilt)

You shouldn't power up a CB without the antenna as a rule - but that won't kill it, however, hit the TX key... quickest way to cook it for good.

Is there any way I can tell for sure if i have blown it?

[CLUMZ1]

Check your antenna hook up as described above... then find someone else with a CB to test with.

Thanks! heres hoping its something simple and not a fried unit.

Or drive down the highway next to a couple trucks, channel 11, ask for a mic check.

UHF PRS. Make sure its not switched to a repeater channel and that you don't have duplex selected. Find someone with a PRS or a handheld and try it on channels other than 1-8.
