Don,

When you enter the menus, as you turn the multi-channel knob, you'll hear a
beep.  The beep is menu 1.  Each menu will also beep, the beep being the
default setting for that particular menu.

For example, if you go into menu mode and are on the default menu 1, turn the
knob clockwise 8 clicks to menu 9.  Right arrow.  The default is speaker-mike.
Up arrow once and you are on TNC.  Up arrow again to PC interface.  Up arrow
again andyou are back on the default.

When you enter menu mode again, you enter on the menu you were last at, so a
good reference is going back to the beep for menu 1.

Ok, folks.  Here are the THF-6A menus:

Menu #:  Default;  Options.
Menu 1: Scan Resume: Time; up arrow changes to Carrier, then to Seek, back to
Time.

Menu #3:  MR Method--all bands; right arrow current band, then back to

on which band you are on.  440MHZ 410-469; 144MHZ 137-173; and for 222MHZ it
is
216-259MHz.
To Change, for example:  on 440 right-arrow highlights 410 and up-arrow will
increase this by 1 meg for each up arrow press; if you down arrow from the
410MHz you go to 469.  If you right arrow again from the 410MHz spot, you
highlight the upper limit of 469MHz and down arrowing will lower that limit.
