RC4 works down here on the Far Side, albeit upside-down.

There are not too many RC4 stations to work, yet, but enough to know it works.  

I believe I've been called several times today by 75-bit users (often on 'my' 
frequency above 2000) that I can't decode so I've been alternating between the 
standard CQ message and free-text messages along the lines of "WSJTX RC4", "77 
BITS ONLY" and "NO CPY 75 BITS" in the hope that some of the undecodables will 
understand why I seem to be so rudely ignoring them.

I will persist in using 77 bit RC4, partly so others who are just trying it out 
have someone to copy and hopefully work.  I'm not worried about duplicates, so 
please don't hesitate to call me again.  Observers on the side will see 2x77 
bit QSOs in progress and might just be persuaded to upgrade to RC4.

Tomorrow, I'll take advantage of the extra bits by calling "CQ RC4 ZL2IFB RF80" 
or "CQ 77BT ZL2IFB RF80".  

With the 2 bonus bits, I had hoped the free text messages might be a character 
or two longer, but no we're still limited to 13 characters ... and still I find 
it tricky to count characters when composing messages on the fly, in a hurry, 
to know where they will be truncated.  The lack of any user feedback on this is 
frustrating.  JTDX handles this nicely by changing background/outline colour on 
the message box when the 14th character is input.  A simple change like that 
would be very welcome in WSJT-X.  [Please don't enforce a hard limit at 13 
characters, preventing any further input: sometimes it's easiest to input 14 or 
more, then move the cursor back to delete superfluous spaces etc. until it 
comes within the 13 char limit.]
