Attractive indeed. Lets see shipping will cost $$$ and my shack can't take
the floor loading.
Darn. I have seriously wanted and at the time would have picked up the
urt23 for $1500.
Fair radio had a few and they were gone very quickly.
I worked on both in the Navy and in fact believe I was the second class
trained on the units so the Navy said. I can't imagine what a urt 23 would
do in ssb. It was easily capable of running rtty at 1 KW all day long.
I also purchased my 1051 from Fair and it was $300-400 but shipping wayyy
back was another $75 and by truck only. Makes sense.
Regards
Paul.
