60mA loops.  Later, 20mA polar loops became popular, but I don't 
remember why.  Wonder what it would be like to work a RTTY contest with 
a "real teletype?"  Perhaps similar to:

Having inherited an SX-28, I decided to work an NAQP CW retro.  I found 
my last 40m ARC-5 and Heath power supply in the basement and fired up 
with a J-38.  I lasted 2 hours before I overdosing on nostalgia.  Unlike 
wine, 36 years in the basement did not mellow the ARC-5's key clicks.  I 
only got shocked from the key a couple of times.

The only reason the "good old days" are remembered as "good" is because 
we had no idea what was coming. :-))
