[TenTec] 546 Omni C Questions

[John T. Fleming]

Ken,

I had an Omni D, Series B, the predecessor of the C.  The RESONATE control
is a pre-selector for the front end.  You peak it for most "noise" on the
band you are operating.

The rig has a hardware noise blanker.  The switch is a pull switch which
turns on the blanker.  The ALC is a variable setting to limit output.

I hope this answers you questions.

73,
John

I have been looking at a 546. I think it might be a good rig for my XYL. 
It has no concentric dual controls, and no menu driven functions. All 
the controls are clearly labeled and visible right on the front panel, 
and there are not very many of them. I think having fewer controls, and 
all the important functions easily findable might be less intimidating, 
to a less experienced ham, than the Omni VI, Paragon, TS-50 or TS-440 
she has access to.

What is the "RESONATE" control? Is this sort of a receiver front end 
preselector tuning or antenna trim control? How about the "ALC/NB" 
control? Is this a single control that has two separate functions, 
perhaps depending on operating mode? Does it work differently in SSB 
versus CW? Is the NB function anything like in an Omni VI? What do they 
mean by ALC? Is this a receiver audio or IF limiting function ( what is 
usually called AGC ), or is it transmit ALC? Is the NB implemented in 
the IF or in AF stages?

Thanks,

DE N6KB
