I can hear my friend but he cant hear me..... swrs on both are fine,,, both base stations, im using a homebrew dipole and hes using an upside down whip stuck to a ceiling grid


First of all, how far are you from your friend? Second, he does not hear you but does he hear anyone else on his radio? If not, he might have a receive problem with his station but it's not his antenna. If he hears other traffic, your signal does not get out. If you don't have anyone else in the area, swap antennae with your friend and this will tell you if it's antenna related or radio related. Let me know what you find out or give me more info! Good luck!

Ranger superstar 33 no recieve


If you're still getting loud squelch noise but do not receive on any channel, you must check the RF from the antenna to the audio stage(not included). There must be more than just one RF stage in this radio. Let me know what you find.

Background noise problem with motorola radius cp200 and also crackling status during transmissions


Bill,
If the crackling and static are coming from the radio, it could mean 1) Something in your environment is putting out RF (radio frequency waves). 2) You have an old battery. 3) You are at the edge of the radio's range. 4) You have a bad speaker in the radio.

Possible solutions for you could be:
1) Have the radios reprogrammed to have Private Line (PL). This would block out RF noise on your frequency. Also, within the factory if there are devices putting out RF noise, there may be some solutions for them.
2) Replace old batteries. (Try a known good battery and see if it helps.)
3) Check to see if you have the same problem when radios are within a closer range. If it is a range problem, education yourself and other users to hold the radio upright (perpendicular) to the ground. You will get the best range. Tilting the radio can reduce range as much as 2/3s. Even the bodyfluid of a person wearing the radio can absorb range.
4) See if you have the same problem with another radio, or if the crackling static is just with the one radio. It may need repaired.

Another solution for you might be a noise canceling remote speaker mic. This would put the speaker of the radio up on your lapel. And these mics also have some noise/wind canceling ability.

There are a few programming things you could have your local dealer try. They may be able to tighten up the squelch and knock out some of the noise.

Best regards.

Cant hear other radios if over 1/4 mile away


Are you using the noise blanker? Are you also finding noise on regular AM radio in vehicle? How good is the connection on the coax?

How good is the antenna ground to chassis? How good is the antenna?

If you address the various sources of general RF hash that would also aflict the AM reception in your vehicle, that would be the first thing to address. It would probably be a good idea to use some contact cleaner or LPS1 and spray down the switches and controls. I know on one of my own that the dirty contacts are enough to kill off reception.

If these things do not improve it, and you do not mind going into the radio- in the reciever stages are a number of 1N60 diodes, and they have a nasty habit of becoming leaky and noisy. Replacing them should help quite a lot if nothing up to this point has.

How do i cut a cb anntena to calabrate it?


If the antenna was designed to be used on the CB band, you should NEVER have to cut it. Calibration is a matter of moving the rod up and down in the post above the coil. There is a set screw that you loosen to accomplish this. Check the SWRs after each adjustment, and adjust until the SWRs at channel 40 and channel 1 are about the same.

If it's a 1/4-wave wip, you get what you get, there are no adjustments.

If you can't adjust it properly using this method, then you have some other problem; bad/poor ground and/or ground plane, bad coax, etc.

NEVER CUT (TRIM) AN ANTENNA THAT WAS DESIGNED FOR CB USE! Period! If it can't be tuned, you either have a faulty antenna, or some other problem. You need to find the problem and fix it, not mess with trimming the antenna...

Can not recieve properly


Mounted on the circuit board is a tiny black encased rx/tx
changeover relay. It is almost in the center of the board and one third to the left (facing the controls) and may be etched MRATA.
I would be looking at that. These sets are subject to a lot of problems as they age and can be fixed with a BIG HAMMER!!
