I see...
On another note, If I have a functioning version of the server and I want to try the new domino modes or other updated features, can I just drop the newest rflinkserver file inplace of the current one to avoid the uninstall and install procedure? If not I think you can point me in the right direction. I have had many failed attempts to upgrade my server version in the past. I know I will need the compatible version of fldigi.. 

Thanks

Hi Greg,
I have tested various multi-carrier modes for pskmail.
The outcome was, that for use in ARQ on HF channels they did not offer the 
improvements I expected, so I removed them. One of the problems
was the use of extended RSID, which gave trouble in  the ARQ timing.
I can imagine that there is a use for multi-carrier PSK on VHF/UHF where
bandwidth and QRM/multipath is less of a problem.
At the moment emphasis is on improving the susceptibilty to noise and
multipath on HF using MFSK modes (DominoEx), which looks very promising...
When that is ready we may think again about use on VHF/UHF, but there the
urgency is lower because packet radio is readily available for high speeds (76 kB/s). ...which does not mean it is forbidden to start a parallel development into 
multicarrier modes, we are open source ;-)

Hi All.
I have never heard an update of whether or not multi-psk modes were ever
implemented into recent client, server versions. There was talk of it
when the modes were first introduced in Fldigi..
