Connex 3300 240-Channels Base CB Radio Questions & Answers
Can I tune my antenna using the meter on my radio?
yes,but you want to make sure your antenna is tuneable.If your SWR is to high or to low you want to be able to adjust the antenna to bring the match up or down.Anything under a 1.9:1 is ok but the lower the better
Connex 3300
sounds like a power amplifier failure. have the rig serviced
Cx-3300
the switch for low and high power the contacts are gone or you need to check the DC voltage to the output section and the voltage drop on TX usually the likes of the cobra 148GTLDX has a bridge board you can remove and add some LCD DVM for current monitors and setting of bias etc so perhaps a regulator has failed or a resistor or the contacts on the switch you need to trace it out using current readings
Radio want stop scanning
your keyboard membrane is needing cleaned with IPA you must have spilled coke or pepsi or somthing conductive on its membrane so i would just look to replace it you need to perhaps replace some capacitors in the controller board section {mpu for it} i think dry caps cause this esp low value ones around the mpu
No transmit signal
Does the unit work when it is not hooked up to the linear? The obvious choice is that you have blown finals in the RF output section of the radio.
Where should I have my rf gain selector hi or lo
rf gain is about local coms if you want your cb to RX far away stuff set it too high but local stuff like friends family that are local then you want too set rf gain to low then only local signal can trigger the squelch ... so the radio will ignore the static and only trigger you when needed ? see what i mean rf gain ye a DX guy will set it high or too listen to people like over 50K away
and let then break the squelch...min
NO TRANSMITT
failed driver final transistors or voltage supply to driver and final
if your RX is aok then chances are the PLL and TX mixers etc are aok leaving only the first answer or a broken mic or TX switching circuit caused prob by a bad mic cable
Power problems power stays on cant transmit or recieve
the power switch is fused shut you need to replace it and also the 5v logic supply regulator has failed perhaps this prob means there is no supply too the PLL and logic
this can all be caused by poor quality cheep power switched employed in every cb ive ever serviced rubbish and cruddy so check for all voltages and when and where you need them work from this
then youll quickly find the issue
3300hp how many watts output, what swr/ power
That style will get about 60w PEAK.. on older styles.. the newer Mosfets will do about 30-40ish..
Meters, are preference.. most are just RMS styles. and you wont see the Peak reading which is fine. there are alot of meters and brands.. Bird, Dosy, MFJ, Siltronix. they all have pros / cons.
if just want simple workman makes some lower end styles. also para dynamics..
there are some MFJ and other brands that have cross needles that show both power and swr at same time. but they will start in the $60ish range and go up from there.
I have a connex cx3300hp i need to know the vr
i have a 10k on a quad mag mount my radio is a galaxy 98vhp peaked and tuned and i talk every where i key on base stations no problem that antenna is a beast you have some issues goin on over there u need to get that tuned i have a flat 1.0 and i run around 250 true watts and my swr never goes past 1.1 you wanna be loud n talk tune that puppy right biggest thing for them is ground best thing is to run it on a huge magnet best ground there is and you have to have good coax that has alot to do with it just tiny little things you have to check make sure everything is set up correctly
