INDUCTOR INF0

       INDUCTOR#                  RANGE UH                     PART#

          L1                     1.4 - 2.7                   KEI106AP

          L2                     1.9 - 3.3                     LA181

          L3                     1.8 - 2.8                   KEI107AP

          L4                     2.8 - 5.1                   KEI108AP

        * L5                     2.8 - 5.1                   KEI109AP

          L6                     5.2 - 9.4                   KEI110AP



       THESE SAMPLES WERE TAKEN FROM A CHINESE/POST UNIDEN COBRA 29LTD



      * THIS INDUCTOR IS USED TO REPLACE THE OEM INDUCTOR THAT CONTROLS
      THE UPPERSIDEBAND TRANSMIT OFFSET IN THE COBRA 148-GTL, MORE OF- 
      TEN THAN NOT, A SOURCE OF SOME FRUSTRATION.  THIS COIL WILL PRO-
      VIDE THE NECESSARY ADDITIONAL INDUCTANCE REQUIRED TO PROPERLY A-
      LIGN THIS OFFSET, AND BECOMES AN ABSOLUTE MUST WHEN THIS CHASSIS
      IS CONVERTED TO 10 METER OPERATION.  (148-GTL)  ALSO, TO INCREASE
      AMPLITUDE AND STABILITY OF PLL/VCO & TRIPLER SIGNAL LEVELS, CHANGE
      THE SMT/VARACTORS IN BOTH THE 11.3258 (OR 11.4758 IN THE CASE OF
      10 METER CONVERSION) AND THE TRIPLER CIRCUITS.  A GOOD HOT-ROD
      VARACTOR SUBSTITUTE IS THE MOTOROLA MV-1404.  ANOTHER GOOD SOURCE
      THAT YOU COULD TAKE ADVANTAGE OF WOULD BE THE OLDER 40 CH. UNIDEN
      RADIOS SUCH AS THE GTL/XLR SERIES, WHICH USED THE MUCH COVETED
      "GREEN" VARACTOR DIODE.  THE SMT DEVICES CURRENTLY IN USE ARE 
      POOR IN QUALITY AND EXHIBIT WIDE-RANGING IMPEDANCE CHARACTERISTICS
      ACROSS THE CAPACITANCE RANGE OF THESE "COMPONENTS".  ALSO, TRY  
      THESE BIAS SETTINGS FOR THE DRIVER AND FINAL STAGES OF THE TRANS-
      MITTER.  2SC2166/ADJ. FOR .62 VOLTS - 2SC1969/ADJ. FOR .68 VOLTS.
      ALL READINGS ARE TAKEN FROM BASE TO GROUND OF BOTH DEVICES, WITH 
      THE TRANSMITTER IN AM MODE, W/MIC.GAIN COMPLETELY COUNTERCLOCKWISE,
      KEY MICROPHONE AND ADJUST TO SUGGESTED PARAMETERS MENTIONED ABOVE.
