[Boatanchors] Dentron MT-3000A Tuner

[KA2PTE]

Got a good deal on this big 2KW tuner a while back and love it. Previous 
owner removed the
built in dummy load resistor and put a new SO239 connector on the back to 
feed into an external dummy load.

For some reason, they removed the factory SWR pcb rendering the meters dead. 
These tuners have a common issue with the
push buttons fouling up, so I was able to get a new set from WD8BXS and 
installed them today ok.

Also got a Russian made Tandem match swr bridge and installed it with an 
adaptor where the old one was, got some photos here with drawings:

So I will have to run some small coax from the new board to the panel 
switches and meters, but looks like this new board only has one
potentiometer for the fwd power feed, so I will have to rig up I guess a 
small pcb near the switches of some kind and mount some more potentiometers
on it for the calibration.

I like the idea of having the meters working as its a quick way to see where 
you are at with respect to F-R power without waiting for a digital meter to 
react.

I am gonna use an in line power meter to ball park the settings and reverse 
the dummy load and transmitter inputs when doing reverse power cal.
Does it look like I need anything else to get this to work? The circuits 
seem pretty identical.
