Repeater updates  – Kent W9KAO

Reports audio on the UHF side working well.  Kent responded to recent repeater hang as follows:  “……. It released when I restarted the system.  Most likely you heard the connection between the VHF system and the Link System.

I did hear an Echolink connection earlier in the commute.  There has been some talk on the HamVoip group that there may be a lockup interaction going on between Echolink connections and the repeater application.  They seem to think it is a stuck Echolink push to talk problem where a user leaves Echolink in transmit mode, but it has been my observation that the USB interface freezes with PTT stuck.  The only solution is to restart the PI operating system.  One suggestion is to implement Echolink on its own node, which is certainly doable, but I don’t think that is the problem, although an active Echolink connection may be involved in some way.

Stuck USB interfaces with this application has been an ongoing issue for years.  This is one of the downsides to using USB interface connections.  In the past it seemed that the longer the system ran without a reboot, the more likely a lockup would occur.  We are restarting the system on a weekly basis, but on the rare occasions, this problem still occurs.

One of the authors of this version of the software was incredulous when I suggested it wasn’t if but when a USB interface got stuck, of course it certainly couldn’t be his software, but it does happen.  There is a reason that at least two vendors provide usb interfaces that now monitor the usb device heartbeat signal and provide a logic signal if it stops flashing.  I implemented two of these usb devices on the UHF system, as there is no internet connectivity to do a restart should the system lockup.  I use the logic signal as an interrupt to automatically restart the system.  We probably should consider doing the same on the VHF system as well”.

Kent requests hardware:  Board approved $120 budget for purchase of two new interfaces.

President’s Report  –  Matt AC9IG

Reports we’re in need of avoiding consternation when there are unplanned events that conflict with planned meetings.  Several events can occur within our large membership and will sometimes overlap.  SARC_All is a public forum for club members so be careful with dialog.

We’re in need for Field Day Chair:  Rob N9MVO can assist and hopefully others will step forward to help him.

Public Service – Rob N9MVO

All Public Service events are over for the year.  Next years public service events start in April and May of 2018

Social

Roger Ryan W9RDR not present; Robert Kocourek W9RKK has stepped forward to become Social Chair.

Education: Leo N9NBH

Reported plans for a winter General Class with the Library District are in place.  September 8th through the end of October at the Hoffman Estates facility, same as last fall’s Technician class.  Publication will be ready for the August issue. Looking for some text on ‘Why do you want to become a General?” as once published.
