[Dxspider-support] Re: Inconsistent user reporting on different DXCluster nodes

[Dirk Koopman]

After this conversation with Martin G0HDB, I had another look at the
PC17 handling code. I have made some changes such that, with a following
wind, a few more PC17s will be sent on than previously. 

I would appreciate it if those of you on CVS would update and restart
and then monitor the situation to see if the user map starts to bear a
better resemblance to reality than has done in the recent past.
