[TenTec] Argosy II Questions

[Bill Mellema]

I have a Argosy II  and have a few questions and would appreciate any 
insight:

1. I have a strong signal on 21.320 Mhz...is this normal? I know that it 
is generated internally. I don't see it mentioned in the manuals specs
2. I am pretty sure I need to rebuild the PTO...is it a big deal to do? 
I am handy equipment.
3. How about alignment of the PTO?

Thanks in advance..
