    HELP : Cobra 29ltd classic horrible growl like squeal

    Mic volume set too high? Frankly the side mic 29s were made starting about 1980. CB us basicallt toast anyways. Buy a front mic panel Cobra 29 year 2010 or newer for about $35 used on eBay. Heck, you may get $15 for old mic on eBay too.

    Average distance for a Bone Stock 11 Meter SSB radio.

    For a base station Flat land about 20 miles. Skip can occur but you need at least 100 watts for many contacts.

    Anybody use switching power supplies?

    Switching power supplies are reliable, but 30mv ripple is high. I prefer Astron linear power supplies with 8mv ripple. However, as a replacement in high power base CBs a switcher fits and cannot be beat.

    Galaxy DX 2517 Problem

    Sounds like a bad final amp. I think 35 watts PEP out is too high for the final. Perhaps a heavy duty replacement is available/

    Two Great CB amps

    500 watt & 1000 watt. First the Maco 200 only uses four tubes yet has 125 watt carrier and makes 500 watts peak out. Some came with 8950 tubes and other uses 6LB6. Replacing the old tubes use 6LB6 and if it has 8950, rewire each set of two tube filaments in series. If good the four 8950 are...

    Cobra 29 GTL Leaked capacitor after 2 years?

    Radio is feed pure DC, there is no ripple current. Even if an audio buffer 1/2 watt audio is loud and cap should survive any audio current. I think you bought a bad capacitor.

    Hex Beam Antenna

    Hex antenna is only 5.5dB gain and needs a rotor. Sirio SY27--4 is 13dB gain and less money.

    Cobra 29 GTL Leaked capacitor after 2 years?

    Excessive ripple current? This cap brand you used can have as low as 105ma Ripple current. I would use Panasonic part number EEU-FS1K470uF 47uF 80 VDC rated at 490ma ripple current.

    Stabilizing Frequency - what do you do?

    Only solution is a crystal heater kit. Wire it to operate when radio is turned off and keep power supply on.

    Ridiculous Amounts of Interference From Neighbors LED Lights.

    Noise is not likely thru the power wires. It is in the air with a watt or so. And, length of the LED string makes a good transmit antenna. Electric company cannot do anything about it.

    Ridiculous Amounts of Interference From Neighbors LED Lights.

    The FCC stopped enforcing noise from electronic devices over 30 years ago. The whole US is trashed by switching power supplies. S3 is now S7 if lucky and normally S9. Your only option is the MFJ-1026

    Varmint 1000 or D&A Phantom

    Old post. Go with D&A if 10 tube Phantom. Cheap 6ME6 directly replaces expensive 6LQ6. Tubes at 90% do not need replacement, produce close to full power at 65%. If 12 or 16 tube D&A go with the Varmint,
