Thank you for the info! I will take a closer look at this in just a bit. I’m
also interesting in Roger’s comment about calibrating the Signalink. In my
case I have two Signalinks – one on the client and one on the server. I have
some links about calibrating and setting audio levels on them. Sorting through
that trying to find something that might help me understand how to know if I
have audio levels set correctly.

OK, looks healthy. The log shows that a PSK500 connection is supported without
repeats.
The modes set in the freqs.txt file set the default mode for the relevant
minute.
So PSK500R,PSK500R,PSK500R,PSK500R,PSK500R, will set the default to
PSK500R in all 5 minutes.
The session modes are set in the CLIENT (Preferences->Edit->modes).
There you set the mode table (check PSK500 and PSK500R) and the default mode
(PSK500R).
On VHF you are allowed to use PSK500 and PSK500R.
There are new versions for client (1.5.7) and server (1.5.3) on pskmail.org,
the new client offers the possibility to change RX and TX mode for the session,
and the new server has less bugs.
I would follow the normal test path:
* send beacon
* send ping
* connect
* send email record
* set password
* disconnect
* reconnect
* get WWV data (info)
* get IAC file (info)
* disconnect
The last one (get IAC) tests if the connection really works, there should be no
repeats
on an FM link. The file is about 3kB, so should be done within 2 minutes.
After that works, you can try the email stuff....
Hope this helps,

Thanks Rein and Roger!
I'm sending this reply from a registered account, and will continue to use it
until the problem with my primary account is resolved. Please let me know if
this one is causing problems.
Roger, I have not calibrated the Signalinks. I'm not exactly sure how to do
that. Can you point me to a link? I will look as well.
Rein, I looked at Google Maps to see if I could load everything up and run over
for a visit. But, Google can't give me directions from Atlanta, GA to Spain.
I hope you're enjoying your RV-time. I'm looking forward to some of that
myself in the near future.
I'm using FM. I will try setting the client to PSK250R and PSK125R. Do I
need to do the same on the server? I tried doing that by editing freqs.txt,
but I get errors when I change that file. I'm obviously don't understand what
I'm doing with that file.
Following is from my original email (which was blocked) with more info on my
environment.
Here is my environment:
Server
Lastest stable release of Ubuntu
FLDIGI 3.21.13
pskmail_server-1.5.0
ICOM-2820H with Signalink USB
Client
Windows 7
Fldigi 3.21.38
jpskmail 1.5.5
Yaeus FT-8800 with Signalink USB
On both the client and server I have Misc/Pskmail set to 1000Hz Carrier
frequency, 10Hz Search Range, 9dB Acq S/N, 10Hz AFC range, and Reset to Carrier
and Report ARQ are both checked. Should TxID, RxID, or AFC be enabled in
fldigi?
Both Signalinks are set up with Tx about 8 o'clock and Rx at 12 o'clock.
Following output from the pskmail server while it is doing this. At this point
it attempted to send an email and failed with a "wrong password" message and
then successful sent that message with no changes to anything.

Subject: [pskmail] Re: Problem With Connection Reliability on New VHF Server
Hi Dan,
it is difficult to see what is happening from an RV on a Spanish camp site,
but am sure we can get you going.
First a few questions:
1.: which server and client versions do you use for testing
2.: Are you using FM or SSB on the VHF link?
The second question is important for the modes you are going to use.
On an FM link you should not have to use slow modes, I would try to limit the
modes
to PSK500 and PSKR500. You can set the mode table on the client, and using 2
modes is
OK when you use FM.
There could be a timing propblem with PTT on one of the rigs.
You can check if the problem is audio related by looking at the raw packets in
fldigi.
Do they show errors? Are all <SOH> and <EOT> characters being received OK?
There is a description on the nuts and bolts of the protocol in the
manual (appendices A and B).
The audio levels can be set also by looking at the small sign near the AFC
button in fldigi.
The level is OK when the indicator is green all the time.
Pse supply some more information, so we can try to help....
On the side, pse use the email account you used to subscribe, otherwise
the list moderators have to manually set the allowance for every mail...
Tnx & 73,
Rein EA/PA0R/M
Hello to everyone on the list! I'm hoping this message actually makes it to
the list. I'm having trouble sending to the list from my primary email
account, and the first two attempts have failed.
I am attempting to set up a pskmail server in the Atlanta, Georgia area for
folks in the local area to use on VHF. I have a test environment set up in
my home, with two low power radios and antennas about 80 feet apart. I have
followed the instructions in the documentation for both the client and server
(I think), and I have also tried suggestions that I have found on the mailing
list.
I am able to connect from client to server. I can send an update to the user
database on the server. I have successfully sent outbound mail. I have also
downloaded mail headers from my POP account. I have sent messages with
PSK500R, PSK250R, and PSK125R. Prior to sending messages inbound and outbound
I successfully tested sending and retrieving mail from the shell on the Ubuntu
box using telnet.
Beyond that I'm not having much luck. I don't seem to have a stable
environment. After a connection and a successful message or so the
connections starts cycling through the modes as if it is trying to establish a
more reliable connection. And, will occasionally see "wrong password"
messages on the server. Many times I end up in a condition where I can connect
but cannot send mail. It seems to just continuously search for a mode and then
disconnect.
I'm wondering if the audio levels aren't set correctly on my two Signalinks,
and that is causing it to miss parts of the messages. But, I'm confused as to
whether or not that is actually true or how to determine the proper levels for
both server and client if that is the case.
I also wonder if I could have it configured as if it is scanning (I’m using the
default freqs.txt file with the current stable release). Is it possible to
set it to a mode and have it only try that mode (or is that a bad thing)?
I apologize if I'm being so vague that it will be hard to resolve this without
more information, but I'm just sort of looking for help in starting to
troubleshoot this. I would appreciate any help anyone can give to help get
over this hump
Regards,
Dan
