After excellent help from Darren, my problem of poor FTA reception is fixed (Batemans Bay/Moruya area is new to TiVo, and required a 'slice".This was most expeditiously done.)
Everthing is working perfectly.....
Except that channel 11 is just off tune (B&W and wormy)
Darren led me through:
a. puTTY
b. telnet connection setting (return key sends telnet a new line instead of M)
c. the bash prompt
d. palmod_config
e. thru the menus to "Fine Tune Channel"

Instead of the screen Darren expected, allowing selection of a channel to fine tune, the following screen appears:
..............
Fine tuning channel 0.
Default frequency is 46250 KHz
A value of zero will remove the entry.
Enter a new frequency[currently 2650 KHz] or 'x' when done.
...............
Have tried rebooting TiVo, saving and restarting from thr palmod_config menu, and generally trying stuff to no avail.
I am clearly not getting the correct "Fine tuning channel" menu.

Can anyone help me resolve this problem?

I am new to TiVo, but wrapped in the concept and ease of operation.

Cheers
