Belongs to a Cobra 29 - but one thing I do want to caution you on.
Your meter reading, you might want to double check for the existence of a tuning trap set up for 52MHz (2nd harmonic) - if it's been tweaked the wrong way - the rise in power may signal your radio may be producing a spurry - a 2nd signal - as a harmonic of the first (27MHz x 2) or 52-54MHz (TV Lo-Band).
You may need just to retweak and balance out the L11 thru L21 mess back there.
The Harmonic trap - if it's there; is L11 and C56, by the antenna connector - that's the tuning slug - it's a "notch" filter so it should not affect 27MHz - if you find it does - check the cap it series tunes with. May be it needs a value range up or down to re-center the notch frequency that filter is made for, and help you balance the power.
