MT-1 Cheyenne Transmitter Questions

[Freeberg, Scott (STP)]

Hi,

I recently acquired a Cheyenne/Commanche (AM/CW) pair.  I have a few
starting questions.

1.  I am going to remove a mod.  Someone mounted a toggle switch on the rear
panel of the transmitter, below the key jack.  It basically connects pin 1
from the power supply connector to pin 1 of the receiver connector.  As best
I can say, it looks like it is bypassing the relay which must disconnect 300
v from the receiver when transmitting?  Is this correct?  Has anyone else
seen this?

2.  Is it recommended to lubricate the main frequency tuning gears?  There
are a couple of metal gears and a plastic gear.    I didn't see any
reference to lub in the manual.   I can feel every tooth when turning the
dial.  At first I thought it was a built in detent.  Now I think its just
rough meshing of gears.

I fired up the receiver and it works.  These will be fun to run on AM and
CW!

Anyone actively using these rigs?

Thanks.
