Hi All,

I have a Kenwood TS-530S, but I'm sure this question applies to
most other tube rigs: Why is there even a TUNE setting on the MODE
switch? I know that with this switch engaged the "input power to the
final section is reduced to prevent tube damage during tune-up", but
why not just adjust CAR (CAR LEVEL CONTROL) downward for this step,
since CAR also controls "carrier level during CW operation". Is it
simply a matter of convenience, or do these controls actually do
somewhat different things?

And while I'm on that subject of carrier level, I need to lower my
100 watts to about 10 watts. Is the best way to do this by simply
lowering the CAR control? Does this technique give all the
advantages, such as more protection to the finals (with a high VSWR)
and generally longer tube life?

Another quick question for anyone who is familiar with the Kenwood
TS-530S with the 500Hz CW filter installed, but I noticed that unless
I move IF-SHIFT counter-clockwise, the audio output is not centered on
800 Hz, but more like 1200 Hz or so. Is this normal for Kenwoods?

Thanks for any help!

Bill,
Do you have the correct CW filter installed?
Kenwood offered the C filter and the C-1 filter.
The difference is the center frequency.

I remember on my 930, there was a pitch control.
Do you have one? If so, how is it set?
