Yeh, EVERYTHING.
There are no shortcuts, Spencer.
The only way you can be sure that it is performing near specs is to align
everything., starting at the front end and working your way through the
radio.
It's quite easy if you have the right equipment for it.
Most often the cause of a poor sensitivity on those older rigs, especially
if it seems to different from band to band is, someone who didn't know what
they are doing (and didn't read the book) has mis-alligned the several
(all?) of the permeability tuned coils in the elevator.
To align that, you will need two signals, one at the bottom of the band and
one at the top.
You only need them one at a time, so it's even possible to use a QRP
transceiver with an A and B vfo.
Let me know if you need more info on this.

Subject: [TenTec] Corsair 560 alignment
I have a Corsair that was given to me. The rcvr sensitivity seems blah, some
sigs on 20 and 30 meters, thats it Puts out full power. I plan to check
things starting at the speaker working to the antenna. Are there any
GOTGHA's I should look out for?
I will use the rig for CW and maybe PSK in the future.
Are there any of the narrow filters available other than new?
