If your radio has a narrow 250 Hz filter you can probably accomodate 4
strong signals per kHz.
If a DXpedition is going to use your RTTY sub band entirely on 20m,
say from 14080 to 14150, you have 4 signals for 70 kHz resulting a
total of 280 channels in the clear.
Now:
- wiping out an entire band theoretically gives you no more than 280
free spots while the callers are many, many more;
- the DX signal is usually much weaker than the callers, finding a
clear spot between all the strong and *wide* signals I often hear
could be very difficult;
- in my country and many other countries the SSB starts at 14101
instead of 14150 as in the USA so the DXpeditioner must be aware of
many local band plans;
- a lot of criticism is heard from those not interested in DXing when
a big DXpedition uses a large portion of the band thus preventing them
from having regular QSOs...suggesting to use the entire sub band will
make more people angry;
- sometimes you may think your frequency is clear while it is already
in use by a station that you can't hear due to the skip so you keep
calling and calling with no chance of being printed by the DXpedition;

No need for jammers to play havoc on the DX frequency, most of the
time we would find ourselves jamming each other.
BT> I think it's worth a try.
I am not sure it would be the best solution.
