Kenwood THD72 tone setting for satellites

Hi All

Looking for some help with setting the tone on a THD72 to access voice sats. I know the tone needs to be 67hz but should the icon on the display read T or CT?

Cheers

"CT" is "closed tone" - where

"CT" is "closed tone" - where you will TX the tone, but also not hear anything unless it also is transmitting that tone!

SO ... "T" is what you want - keep RX "open tone."

On Yaesu, TSQ is "tone SQ" - both TX and RX. NOT what we want - just a TX tone.

Personally - out here in So CA - I never program terrestrial repeaters "closed tone." Most do NOT transmit their tones
through to the output. But for those which do - what if I was closed-tone on the local machine, but there was a conversation
occurring fifty miles away on the same frequency pair? I would be guilty of unintentional interference. Keeping my "top fifty"
or so memories in my mobile rigs "open tone on receive" causes no problems whatsoever ... and it makes me a more responsible
ham ...

The four memories i DO have "closed tone" are a couple weird simplex freqs used for events. But, as we always should, monitor
even those freqs for traffic to make sure you are not interrupting anyone.

SO-50 is somewhat special

Its tone is 67.0 Hz, however, you may need a one time shot at 74.4 to turn on the repeater. If you know the sat is there but you're not getting in and don't hear any other stations, try 74.4Hz, but just once.

You should have T on the display, CT stands for CTCSS, which is not what you want in this case.
