Does anyone on Greenkeys use a Mititary UGC-74A model? 

There seems to be a diffetent startup print out between  the A and B units! My unit prints all ok from a 60ma loop and terminal  but I cannot get it to transmit?

Most say the A units are not usually usable because of the degraded Rubber feed rollers but I have found a good working repair for that if anyone has an A unit they would like to operate, 

Thanks Jeff W1AEA
