[Trlog] Using Post to update TR Master

[n6wg at comcast.net]

I'm trying to understand how to use Post to update my TR Master.
During practice, I'm seeing a lot of calls without Sprint-type info
with them.  I'd like to use my previous Sprint logs to update
TR Master, but, as someone else said, the manual is rather
cryptic.
Has anyone written anything to amplify on the manual writeup?
I have a lot of questions that just don't seem to be addressed by
the manual,.
Thanks and 73
