There's been a great deal of research done into the problem by folks who have extensive experience in mobile radio work. The main thrust for Ford issuing at TSB was that the problem was so severe it

I don't know about the rant, but the technical problem seems to be the voltage rating of the ceramic disk capacitors used to bypass RF on the HV, which are located on the meter shunt board. IIRC the

In most all cases of "multi mode" amplifiers, Class AB2 is used. Class A is nearly perfectly linear, but is never more than 50% efficient, which is unacceptable at most moderate to high power levels.

Indeed, this is a well-known issue! I have found that using higher impedance headphones reduces the difference in levels, but it's still pretty noticeable. It's one of the unresolved issues on my Ori

I'm afraid it's not that simple. Looking at the schematic, identified as "566AUDIO Model (1).pdf", you can see one of the more significant differences between the Orion and the Orion II. The O2 runs
