[TenTec] Omni C not for 17M?

[Curt]

Recently acquired fairly nice Omni C, a model which I have never owned.  It 
lacks crystals for 12 and 17M,  recall reading  posts stating that 17M 
wasn't useable on this rig because the mixing scheme allowed it to put out 
birdies violating spectral purity regs.  I'm recalling mention of birdies 
1-2W on 17M (?!)

Just wanting to confirm that this issue was never corrected, and that 
operation on 17M must be avoided.
