[TenTec] Orion II tuning questions

[Henry Pfizenmayer]

Grant -I think it is interesting also - but I am tired of the smart alec 
lectures from the reflector - so from now on all my comments will be to 
individuals or to TenTec directly rather than on the reflector.  Thanks for 
the reasoned comment.

 By the way the non - changing freq with key down was found on a dead 10 
meter band whne I wanted to do a quick sweep of the swr on my KT34 to make 
sure somethimg had not changed . Lo and Behold - the SWR just sat there as I 
incremented in what I thought were 100 khz steps  Hi Hi .
