My only main concern, since you couldn't check SSB, you wouldn't know readily and right away...
L50 - needs to be a Ferrite Bead, not a resistor...Look for it and change it out - any Ferrite bead will do, just not a resistor -They used a Resistor - so it will affect the ability for the PLL to stay stable in SSB load conditions.
You don't need it...change it back to a Ferrite Bead...It handles the Cap right next to it too, Supposed to filter but you'll see what I mean when you try to make it work on SSB - or if you'd like - AM you'd hear some "Warble" when you tune the Monitor radio to listen in to the audio on the AM side of the Malaysian 148 - set the Monitor radio up for USB or LSB and tune in, then start talking on the 148 - you may hear a "warble" as the carrier the 148 produces, "vibrates" on the voice peaks - makes it hard to listen to when you drive it with a power mic.
