Steve, If you use .66 for the velocity factor of RG-11 and 147 MHz then it comes out to 66.25" which is within 2.5" of the text. I've found that on these harnesses, the length is so critical that the connectors must also be included in the total. I'd bet that this accounts for the difference in

Youre confusing levels and deviation! I always strive for the deviation limiter at 5khz,use a 1khz tone at 3khz deviation in and out and CTCSS at .5khz out.They dont add up together like you think they would,so 3.6 is not what to shoot for,do them separately!You can get fancy and plot the response
