[WriteLog] low tones

[Ron St.Laurent ND5S]

Hi Jerry,

Have you tried the TPF Twin Peak Filter on your ProII?  It is a great tool.
It "enhances" the mark and space tones on a given frequency and I have
copied stations I would have otherwise lost.

Put your rig in RTTY mode.  On the buttons just to the left of the display
push and hold RTTY FIL, this will bring up a sub menu.  Turn Twin Peak
Filter ON.  When you look at your MTTY "histogram" display in receive you
will see how the frequencies at mark and space are enhanced.  With your RTTY
FILTER ON and exiting the menu you will see TPF on the top line of your
display showing that it is activated.  Neat toy!
