the rare times they are needed.
IMO, if a system is using the internet to pass routine

Bob,
In the disaster relief agency I work for, our radio operators are 50% ham radio operators (80% of these are only techs and don't even own ham radio equipment). That probably means that perhaps 10% are general class or higher.
If QRL? in CW is too retro, we could specify a sequence of eight 1
khz tones of 250 ms duration separated by 250 ms to convey the is

waterfall display, and could easily be recognized by application
software.

It is not necessary to decode in order to sense a busy frequency; it
is only necessary to detect any of the underlying forms of
modulation in use. There are far fewer modulation schemes than
modes. The SCAMP prototype demonstrated the effectivenss of this
approach.

How about something as distinctive as RTTY's RYRYRYRYRYRYRY? We all
recognize RYs without decoding it with a terminal. Your tone idea
is good, anything that is easy to recognize with the ear would be
good. I wonder how QRLQRLQRLQRLQRLQRLQRLQRLQRL sounds in RTTY?

Yes, but If I understand it correctly Harv's product is an OS and some ham files . If I use this cd and create a bootable Linuk OS, will I be able to load other Linuk software , PSKMAIL for example ?

I have used Winlink occasionally, and have not experienced any
contention when attempting to connect. I have not tried NTS-D.
Trading absolute efficiency for dramatically reduced QRM -- and the
frustration it generates -- seems reasonable to me. If the QRL
