Hi Dave, Based on your posting/description, a couple of possibilities. You have to check the settings of your RF Gain control, Automatic Noise Limiter and Switchable Noise Blanker also your Squelch control. Further, pls check your RX signal, if the incoming signal is strong say S5+ but no audio, then perhaps there is an internal problem with the RX/demodulator circuitry. If fiddling with the front control(s) does not solve the problem, then perhaps you need to seek the services of a qualified service technician. Sometimes, the USB, LSB switch can also casue similar problems. Good luck and hope this be of some help to you. Kind regards and 73s.

    Hi all,
    I guess the "Guest" might be right, might just might be a simple case of bad internal speaker although the Cobra 148 GTL in my experience is not prone to such defects (now if it were a Midland or a President then....) Cheers all.

sorry to hear about your misfortune but unless you are willing to take the drill totally apart and clean the inside and reset the tracking and bushings it would probably be cheaper and easier just to purchase another one now that Christmas has come and gone you can get one at a pretty good price

try turning the wheel while turning the key you may need to put some muscle behind it. if that does not work try shift the car from park to neutral.

97 VW Golf Automatic wont start, battery fully charged


MY guess would be that it's the starter, with an automatic transmission, if the car is not in park or neutral, the car wont even attempt to start, so the clicking sound you say you hear rules that out. Now, im not an "expert" or anything just a guy with some general knowlege, so before you do anything i would recommend having it looked at, but if you feel confident enough, the starter is where i would begin, hope this helps, and good luck.

Back speaker sound


Why would you only hook up one speaker for the rear channel? in 7 channel stereo, all speakers have 100% signal sent to them as "stereo" in Dolby digital, rear speakers are for "effects" not dialog. like a plane flying past you or a car driving by, that's when you hear a rear speaker. It also needs to be placed behind you, not next to you or in front of you. Unless you are using zone 2 & 3 the receiver's surround back will work. if you only have left,right,center,sub & rear; the rear speakers should go to surround speakers not surround back. If you still have questions, post a comment and I can explain further. Hope this helps
