Ok, so I tried unplugging and replugging the antenna, just to make sure 
that femon would pick up the crudest of changes, before I tried more 
refined ones.

I got the following, but it also crashed my machine :-(

rogan@athena:~$ tzap "eTV(ETV)" > /dev/null &
[1] 5339
rogan@athena:~$ femon
using '/dev/dvb/adapter0/frontend0'

This would seem to support the notion that I am not getting a good 
enough signal, right?
