I drive a truck for a living, Ive always had a good cb. Recently I just switched trucks that already had 2 antennas set up with all the coax run in it. I put in my cb and I am not recieving any thing farther than a half mile, however I can send for at least 2 or three miles or better. Not sure what to do short of ripping out the coax and putting on new antennas. Any suggestions?

Re: Getting out, but not recieving well...
Initially pls check the grounding of both the antennas and/or their mounts. Thereafter, an SWR check/reading would also be good as it will not only tell you how efficient your antenna is in transmit but likewise in receive.
Additionally, a two (2) antenna set-up (twin tracker) is directional and therefore would have blind spots on either sides and being on a truck (especially with load/trailer) probably even at the back.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

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
hi iff you remove the mic does this squeel disapear ,if so i recomend that you open mic casing and check for any lose strands of wire that could be shortening out ive seen this happen so many times with microphones you can get some switch oil and apply sparingly to switch this will also help in the long run ,,,,,goodluck with it
Check the ground. Make sure its grounded well on bare metal. To see if the ground is bad, or not making good connection, disconnect the antenna and turn it on. if it does not power up, that means your ground is bad, and it was grounding only through the antenna.
Make sure not to key up with out the antenna connected.
I know the recieve adjustments are ( and make sure you adjust in this order )L9,L11,L12,L13,L14,L4,L3,L5,L6.Adjust them for highest recieve you may have to go through them a couple of times.And again do them in the order I gave you.VERY IMPORTANT!!! Good Luck
Are you using the factory coax. A lot of Internationals have a terrible setup from the factory, they run the coax into a junction box and run your cb coax and your fm radio out of it. You could be getting bad rf feedback through from the FM radio. I would next try a regular antenna mounting bracket setup with a good stranded center coax with at least a 95% braided shielding. You have been on the right track, most problems like this is a process of elimination. If this doesn't fix the problem, or you already have this setup, please reply on here or email me at:
Hi, You can obtain these parts at www.rfparts.com. the 1969's are around $5.50 and the 2166 is even cheaper.Good luck. If by some strange twist and you cant get them from the source I recommened , get in touch with me , I run a CB Radio Repair Shop and I do have these parts and will sell them to you but you would probably be better off ordering them from RF Parts.
A couple of switches and knobs you can check (if present in your rig):
1. auto noise/noise blanker switch - try off position;
2. dynamic squelch control - lower down setting;
3. RF gain - should be at max (clockwise); and
4. Delta Tune - normally should be centered.
Hope this works out for you and give you an idea where to start. Good luck and pls post again how things turn up. Kind regards.
