[RTTY] The other guy's TX is reversed

[Robert Chudek - K0RC]

When you hit the PTT when your transceiver is in FSK mode it, may transmit either a mark or a space. Then when you close the FSK input, you will shift to the opposite tone. The manufacturers can't seem to agree whether an "open FSK input" is mark or space.

P.S. I've got a Flescher TU-170 including manuals for sale. Looks like new. The WU Model 100 is long gone!

I have been on RTTY going on 35 years now.
I mean how hard can it be. I don't recall seeing so many
up side down before computers and software. I still use
a 28 machine and an Hal ST-6 with a Kenwood TS-520.

You put the rig on LSB and have at it. I really don't understand
