       Cobra 150GTL (PFM-0089A-BB) Transmitter Alignment Procedure
       1. Set transceiver to 27.405 MHz Band: B Display: 40
       2. Test Equipment Connection: Connect RF power meter VTVM and
       oscilloscope to antenna jack
       3. Adjust: T 718, T 719, T 720, T 721, T 722, T 723 to obtain
       maximum indication on VTVM
       4. Change to frequency 26.065 MHz Band: A, Display: .1 and
       29.695 MHz , Band : D, Display: 3.5
       5. Adjust: T 721, T 722, T 723 to obtain maximum indication
       difference between 26.095 MHz and 29.695 MHz on the RF power
       meter
       6. While on AM TX mode, no modulation and Hi/Lo power switch on
       High, adjust RV 9 to obtain RF carrier power of 4 watts on power
       meter
       7. While on AM TX mode, no modulation and Lo/Hi power switch on
       High power, adjust RV 1 so that meter indicates +30
       8. While on AM TX mode, AF signal 30 mV , adjust RV 12 to obtain
       90% (negative) modulation
       9. While on FM TX mode, AF signal 30mV, adjust RV 5 to obtain
       2.5KHz deviation
