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.
