    Malaysian Cobra 148GTL tune up

    Hi Guys I wanted to tweak my 148. I found this procedure.
    AM power is VR10. if running a linear, turn this down to 2 watts. if not, no more than 5 watts.
    SSB power is VR11. turn this up to 15 watts, no more.
    modulation is VR7. turn this all the way up, and dont clip any parts.

    Is this correct?
    And not to sound dumb. I can check the watts using the wattmeter on my swr meter with a 50 ohm dummy load on it and as I adjust ,keying the mike as I turn it up correct?

    Thanks

    be careful turning modulation up too high, you might cause distortion. A little at a time.

    CBtricks.com should have what your looking for.
    The watts sound ok.
    Though as already said. Keep the modulation about 80%.
    Then run a power mic.
    I love the Astatic Mobile Max echo box. If you can find one.
