Trying to find someone to fix the night watch feature on my cobra 29 ,the local cb shop won't touch it,and I really don't want to do it myself looks like it could easily be broke. Any help would be...

its time consuming and more costly to fix unless you're doing it for yourselfyou need a multimeter and a schematic for the elec.out put of the components that run the N/W ground the meter and have at it to all the lights on the dials then go to the main IC and check may be as easy as a bulb in each dial or having to replace each dial with a new one. thats why he wouldn't touch the radio.

Fm adjustmet for the galaxy dx 29hp

Do you mean the FM Deviation or Detector Adjustment? I haven't found a schematic on the DX29HP yet but it may be the same as the DX33. NO GAURANTEE! The DX 33 has VR5 as the FM Deviation. You'll want to borrow or buy an FM Deviation Meter to adjust that. The FM Detector is L5. You'll need to Connect an AF VTVM or scope to IC2 Pin 7. In FM, Set FM RF Generator to 26.965 MHz (CB Channel 1) and at a level of .5uV deviated 3 KHz with 1KHz audio tone.
Reduce the volume as you need to. AGAIN!!! THE DX29HP MAY NOT BE ANYTHING LIKE THE DX33. If you are not sure, please pay someone to make the adjustments for you. It's a pretty nice little rig.

When the radio is powered up a a constant buzzing noise is present. This noise is at the same audible tone when the radio is set to any volume level and whether it is set to CB, or weather selection... ...

If this is a high-pitched tone it probaly is from the DC-AC inverter that provides the high voltage to light up the front panel. Normally, this is barely audible, but I've seen a few that are loud enough to be annoying. It may be possible to install a small filter in the power line to the inverter, inside the radio. I've never tried this but if the inverter is the source of the noise, this will be the most practical way to isolate ite & eliminate the problem.
This should onlty be attempted byan experienced CB technician.

For some reason, your posted DX40V is not listed among the Galaxy CB Products.

You can visit their website and check the product listing. You can also try viewing their Product Line page to compare the front panel features. You can also mail in your concern/request to

Additionally, you can post back with what features you want information on by naming them such as NB/ANL, RF Gain, RF Power, SWR Alert, etc.

Hope this be of initial help/idea to you. Pls post back as requested.

Good luck and kind regards.
