Re: Staying Connected to DX Spots

John Huber

For those having the telnet disconnect issues with ACLog, but VE7CC (CC User) runs all day, you could do like I do.
I run the VE7CC “CC User” as my ONLY connection to any cluster, ever.  Why? Because of the versatility and ease of configuring filters AND because I can then use that running instance of VE7CC with all my radio software that accesses a cluster and enjoy/exploit the same filtering.
I did NOT implement this solution to solve a staying connected problem.  I hope that those experiencing the issue have not overlooked the ACLog “Enable 3 Min Keep Alive” option on the DX Spotting->Configure window.
On the VE7CC Configuration menu –> Ports/Logging Program, in the Logging Program Connection section (center area), I select “Enable Telnet” and “Use Port 7300”, and APPLY.  Feel free to adjust the “Data Sent to Logging Program” selections for your operating preferences.
Then, in ACLog, in “Settings->DX spotting->Configure”, select the Data Source “Telnet Host” (probably already selected).  Then set the “Telnet Host” to “” (the loop back address for the PC on which you are running ACLog AND VE7CC), and the “Telnet Port:” to 7300.  Enable DX Spotting and now your spots are filtered by VE7CC.  With this setup I do NOT have the ACLog “Enable 3 Min Keep Alive” checked.
I have tested on my home network with running ACLog on a separate PC from the one running VE7CC.  It works just fine.  Configuration of ACLog is the same EXCEPT for the Telnet Host.  You must supply either the IP address, or host/computer network name, of the system running VE7CC.
For reference my VE7CC and ACLog pc is running Win 7 Pro, and I tested ACLog from a laptop running Vista.
I also tested with a copy of the Michigan QSO Party program too.
I also have connected my N1MM+ to the VE7CC instance with no issues.  Even both ACLog and N1MM+ at the same time! Obviously, only one program can control the radio at a time and that’s okay. I did it mostly as a proof of concept, and to be able to reference things in my ACLog occasionally in the midst of some contest.
I hope this helps at least one those with the “not staying connected” issue.

Hi Gang,

I would also like to find out if there is a utility or a fix for this anomaly.  I have the same issue.
I’m good for approx a half hour 45 min or so before disconnect.  Running Windows 7.
If I run VE7CC by itself it will stay connected all day.

Hey Steve.  Thanks.  You don’t by any chance know of a utility that will send  a ping to VE7CC with a “-t” switch every second do you?  Also doesn't anyone think it odd that my connection has been 95% OK for the last couple of years and now it’s like do-do?

I suspect that Scott and John are on the right track to your disconnects.  Something else that will cause this problem is the “aging” of the translation table in your router/firewall.  If the firewall doesn’t see regular activity between your computer and the telnet host, it will remove the entry from the translation table.
You might be able to keep the translation table entry active (depending on the router software) by running a continuous “ping” from your computer to the telnet host.  Open a DOS Command window (run the program “CMD”), then use the ping command with the “-t” switch to ping the telnet host once per second.
Good luck!

Hi John.  Thanks for the input.  I tried that several days ago.  No luck.  But thanks for the suggestion.

Make sure you have 3min keep alive checked. If spots are 
coming slowly many spot servers will disconnect clients if 
they don't see a 'ping' or ack from the client within 3min.
