I just installed the OT-11P AT in my Orion II. It works but not as the 
Manual sez; for instance, manual states, "press and release Tune button 
which will start a tuning cycle and when complete, the word "Tuned" will 
appear in the display. This does NOT happen. It also states that the 
tuning cycle will auto end in a few seconds. This also does NOT happen 
as I have to manually hit "Tune" to disengage the cycle. Finally, the 
manual sez that approx 20w will be transmitted  but it appears that I am 
getting 50w or so during the cycle. Other than that, it DOES tune the 
antenna, "40M CCD" and works pretty well, with SWRs all below 1:2 to 1. 
Better yet are the results; antenna apex 35ft with ends about 18ft. Last 
nite was first op with the CCD "Constant Currrent Distribution" and 
worked HI on 17m, 6Y, TA3 on 20m, YU, IS0 on 40m,  this morning ES on 
30m and EY on 17m. All cw contacts. Antenna exhibits good low angle 
radiation.

Anybody care to comment on the LDG tuner? I know it originally was for 
the Orion I so maybe the procedures/display have been changed...
Finally, after putting the tuner in, I have pretty much lost the cw 
sidetone volumne, "100" is pretty weak plus the volume on the radio is 
about 1/2 even when wide open. Same if I use an ext speaker; most weird 
is that using the headphones does not mute the speaker...back inside to 
check on wires and connections...
