Hi Robert,
Please see my answers next to your questions below.
All normal, except the symmetric connections when it seems RSIDs are
decoded properly (see my comments below).
Best regards,
John (VK2ETA)

Please help me to understand what is the problem. Here we go below is a log
from my server. Also, version 1.5 - from I understand the only change made
was blocking PSK500 on US side, or anything else?
[The mail count = -1 means that the server cannot get that call sign's
email list. Most likely because that call sign does not have his email
records on your server. He needs to do an "update server" first]

[Yes, in the absence of reply to its polls, the server will alternatively
downgrade its TX and RX modes until it gets a reply from the client. Here
we have two successive misses hence the downgrade to MFSK32 then THOR22.
You will notice that there is a re-upgrade to MFSK32 as well after the
receipt of a good reply from the client (just before closing the
connection).
Note that the connections you had are in what we call symmetric mode
meaning that the RX and TX modes are always the same. That normally happens
when the server's Fldigi does not decode an RSID just before the connect
request. We therefore assume we have an old client that does not know about
asymmetric modes.
But in your case the server does not seem to respond to the RSID and
assumes non asymmetric mode. This is not major but we need to understand
why. This is visible by the "final connect status: asymmetric link: 0"
information from the log.
I would check that in the Fldigi preferences you have the ID settings as
per the Pskmail manual. Otherwise it could be a bug. Let's see if you have
the same issue with 1.5.
The mode down/upgrade works well otherwise.]

[In symmetric mode we need both averages to be above 85 (from memory) to
perform an upgrade. See the next exchange with re-upgrade to MFSK32.
In asymmetric mode the TX and RX modes are manages separately. ]
