Flashing red light on radio where it thinks its recieving. Transmits fine but does not recieve.


Three things come to mind:
1) The radio is receiving, hence the light, but you may have a different PL code than the other radio and it is muting the transmission. Check your programming to be certain both radios are programmed alike. The red light indicates activity on your frequency.
2) Your radio may have a problem with the receive side of the radio or a bad speaker.
3) The transmitting radio may have a problem with transmit. This can be a sign of a bad battery. Swap batteries and see if the problem moves to the other radio. If so, replace the battery. (It takes more energy to transmit than to receive, so loss of transmit is common with a bad battery.)
Best regards.

Is it best to use in am mode in normal trasmitions on a cb radio dx 959 galaxy?


  • This Galaxy was built as a CB to run on AM (11 Meter). The majority of people on the CB run AM stations. Sideband (upper and lower) is where the carrier is removed and the wave being transmitted on is cut in half. You can do this just fine but mainly if you want to talk to someone and you both know your going to be on Sideband for a little privacy. 38 LSB is a great channel to catch some DX side band on world wide. But yea, AM is the best to find people to chat with.


  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Sideband carrier??


im not sure carriers are measured in pounds, but SSB is a supressed carrier mode, in SSB only one sideband is transmitted and the carrier is inserted at the other end in the receiver. In AM mode the carried and both sidebands are transmitted. with regular am there is a carried and when modulation (your voice) is added a signal appears both above and below the carrier frequency at a distance relative to the frequency of your voice. so if you have a carrier at 1000 khz and modulated it with a tone of 100 hertz the signal will contain frequencies of 900,1000, and 1100 hertz, then its changed to SSB by supressing the carrier (1000) and one sideband (1100) if you are on lower sideband and (900) if you one upper sideband, and transmits the remaining frequency.

FR60 intermittent transmission


Hello snorker,

It could be battery / power issue. Two-way radios draw much more power when transmitting then receiving. If the batteries are weak the radio might work perfectly fine on receive and then cut-out when you depress the Push-To-Talk.

Best Regards,
Ken

Cobra 148 gtl


Open the radio up and find the L22 Can/Pot. It's the one with the wire soldered on top. With both fine and coarse Claifier/Voice Locks in the 12 O'Clock positions, confirm, then listen for someone that is on the correct frequency and turn this pot (small ferrite core inside) with a small plastic preferred screwdriver, until they sound clear. Do this for USB as well except, the Can/Pot is L59. Don't adjust the VR5 (transmit) unless you need to.
