       Cobra 29 GTL/LTD/Classic Repair Tips
       1. "Motorboating": Locate C242(.001)on pin 5 of TA7222 audio ic
       and move to pin 4 of ic.
       2. Weak mic gain: Some raios have a 2SC372 mic amp. Replace with
       a 2SC945.
       3. Receive on adjacent channel: Bad solder joint to C131 (next
       to 10.240 crystal).
       29 LTD:
       1. OVERMOD: Check D11
       2. PLL dead, no TX or RX: Shorted C112
       3. No TX/RX with Channel LED lit on RX and then goes out when
       keyed: Bad /shorted C119.
       29 LTD Classic:
       1. OVERMOD: Check D11. Missaligned VR4.
       2. Internittent audio/modulation: Bad solder joints on pins 1&2
       or 2&3 of audio ic.
       3. TUNE UP TIPS: L11 is the TVI trap. DO NOT adjust!!!
       Stretching L12 gets moe output. L14 peak is about a turn or two
       up from factory original setting.
