This is the modification for the New Cobra 148 GTL D MMB8719 PLL.
it works perfectly full coverage from 26.815 to 28045.
a few channels you will have to slide down to but they are there.
The ones marked missing on the chart can be reached by going to the next highest channel
and sliding down. Slider goes 11 Kc down and 6 Kc up.

Parts recommended for this modification:
1. a 2 pole 6 position rotary switch
2. 2 1n914 diode
3. replace the (voice lock) with a
20K ohm 5 or 10 turn linear potentiometer
NOTE:
the hole through the chassis for the switch and voice lock are 1/4 inch
i had to drill them out to 3/8 inch
i used a 5 turn 10K ohm pot for the voice lock it works great and its rock stable
if you experiance worble on transmit mount a separate 9 volt regulator
to the chassis and use that for the hot side of the voice lock .
