KISS. Keep It Single Sideband. Not many can do AM and even fewer have

And the anoying thing about nets is the ionisphere can't tell time.
That said, it is much easier to do coast to coast now with WebSDR. Go to

This would be cool. Since it'
I'd be interested in a classic computing net as well. I have 40 - 10
meters available on HF. Our area is lagging in digital repeater coverage,
so no Fusion or DMR or D*Star for me just yet.

Is there a potential problem here?
I have an 11/53 microPDP11 with a RQZX1 controller connected to a single

The autoconfigure setup in the RQZX1 puts the hard disk at DU0 and the
Floppy as DU1. OK. I boot RT11 from the disk, V5.7. Works fi
