Eric..........
 
I just picked up and installed an MFJ Model 1708 RF controlled T/R switch  
from an add in Electric Radio
 
I am using it with my HB pair of  HK-54's  (triodes similar to  812's) and 
my 75A1 (about 300 watts)
 
It is a neat little box that can be controlled by PTT or RF sensing....The  
PTT and the aux contacts are  brought ought to  RCA  jacks...........Along 
with an adjustable delay..........IT WORKS GREAT
 
I have several Dow type relays but I have found that they become noisy and  
intermittent
 
New, it costs about the same as a good DOW with external contacts that you  
would find used.  About $59.00 or so.........You can see it on the MFJ  
site..... _http://www.mfjenterprises.com/_ (http://www.mfjenterprises.com/)  
 
I bought it for much less but that was lucky
