A comment from a 6m op in Cedar Rapids, IA:

I have had the pleasure of working dozens of Texas hams on 6m during the
past 3 years whenever the band has opened to my south and southwest.  There
are plenty of 6m ops in TX, and although Texas has a fairly large
population, I have run across some grid squares in which I have worked both
of the known 6m ops in those squares.  So, let's not get too casual about a
30 to 50 MHz BPL system and its potential for mayhem on a significant band.
If the system can contain itself (meaning fast rolloff above 50.0 MHz),
maybe it won't be too bad.  But, let's also not forget those doing 6m EME
and other weak signal work near the bottom end of the band.

As for those unfortunate fire and police departments who still use low VHF,
don't forget there are also some low VHF business comms mixed in there, as
well.  Gee, doesn't interfering with those guys consitute a hazard to the

"minimal RFI" presumes the following:

1.  They install everything according to spec.
2.  They maintain everything to spec.

So, in theory it is just 6M and above that is
subject to RFI ... unless there are additional
artifacts from the generation of their 30-50MHz

We shall see ... ;-)  doc
