The three 2100s are pretty much the same, but:
2100F (for "f"ront?) does frequency monitoring and has local front panel
control. GPIB is an option.
2100R (for "r"emote?) is equivalent to the 2100F but has no front panel;
you set the GRI with thumbwheels and it just takes off with no other
operator intervention required. I think it has GPIB standard to allow
2100T (but actually, Austron seems to just call it the 2100 without a
suffix) does frequency and timing -- it can generate PPS sync'd to the
LORAN time-of-coincidence with UTC.
The older 2000 receiver does frequency monitoring and requires manual
signal acquisition using a scope. It's quite a pain to get running, but
a great way to learn about how LORAN works!
