Rein/All, Thank you for the ideas on this matter... They make sense... The one especially considering that RF could be "getting" into the radio causing this to happen. This is annoying problem that I would like to fix and will consider putting ferrites on the cable. Not yet, I want to explore the settings more closely before I come to this. I anticipate trying your suggested changes soon.... Which brings me to the fact that I would like to understand a little bit more about the settings. First of all, what is the difference between RigCat and hamlib? I understand the principle behind hamlib but not sure about RigCat other then its role with rig control. What would cause it to conflict with pskmail server? Is it a matter of just using the two can cause confusion and problems? The strangest thing about RigCat is that I seem to remember it being suggested to be set for pskmail server. I dont remember where it came from... Just so I understand it correctly, running two programs with hamlib is possible and not cause any problems? Anyway, here is the second one. I just was reading some responses (WB2LMV) as was seeing that pulseaudio is being "portaudio" device in fldigi. For some other reason, I don't use pulseaudio, but straight ALSA devices. What is the difference? Is one advantageous over the other? Though, I did experiment slightly with pulseaudio on Fedora to see if it was "causing" my problem but started to work but was failing for some reason (volume levels were set accordingly but was getting no audio but just PTT and then eventually I could get the "constant" PTT). Any thoughts will be appreciated.. 73 Josh, AB9FT ________________________________ From: Rein Couperus <rein@xxxxxxxxxxxx> To: pskmail@xxxxxxxxxxxxx Sent: Thursday, June 28, 2012 2:26 AM Subject: [pskmail] Aw: PSKMail Server & IC-7200 Josh, There is one thing which comes to my mind immediately... The PSKmail server uses hamlib to control the frequency and the PTT of the rig. I expect problems when you use RIGCAT. Attached is the pic of the parameters I use on the PI4TUE server. I use VOX instead of PTT, that works very well. The lockups you see are most probably caused by RF on the USB connection. On PI4TUE I have used ferrites to kill the RF on the cable, additional to effictive grounding of the rig. We have strong indications that lockups are NOT caused by the server software. The operating system does also not play any roll, lockups happen on any... The fldigi problem is caused by the error handling of the ARQ interface in fldigi. When RF causes errors on the USB connection, the error is not handled properly in fldigi, and the ARQ routine is halted. I have meanwhile written a small scipt which will restart fldigi after 5 minutes when the ARQ interface dies. It is being tested on PI4TUE now, and it will be published soon... But the best cure is to make sure the USB connection does not produce errors... 73, Rein PA0R All, Name here is Josh, (AB9FT) from Sheboygan, Wisconsin (50mi N of Milwaukee along Lake Michigan) 30m conditions haven't been the best here past few days, if that is why some have not heard the server here. Trying out KAM+ on 30 (test propagation) and actually hearing very little as well. More one way with "packet" TX/RX then with PSKMail I have very regular copy of KB2PNM on 30m... Anyway, I have been having a problem with the server here with my IC-7200. It is a random problem that has no specific time but seems to eventually happen.. It can be either in the ID (where I have noticed it happens more often) but simply when its done transmitting, it gets "jammed" and continues to transmit until I turn the radio off. When that happens, fldigi apparently hangs and have to "kill" it. I am wondering if my problem is related to anyway to SA6BQZ's problem.... On some cases, it loses communication with the radio with a message about (Radio IO failed....). I should mention that I have it set up that it uses RigCAT with the IC-7200.xml that keys up the radio and has that special "command (can't remember, its not NO500....)" to ensure the 7200 can key up with PSKMail Server I have tried to troubleshoot as much as I can and getting nowhere with it. Started with different USB cables... Tried different linux distros (Lubuntu, Xubuntu, Slackware, Fedora, Mint, Debian) and different software combinations (newer/older versions) and get the same thing... Also, it happens whether I use frequency/scanning.. Pretty sure, its nothing I have set up for files, but send them if that will help. Beginning to wonder if its the computer, but that would be strange.... If anyone has any suggestions, please feel free to mention. Thanks. 73 Josh, AB9FT
