RPi 3 controller problem
Good day! We have recently replaced the CAT-200 controller on our repeater with a Raspberry Pi 3 running the Dial RC1 distribution. Mostly it seems to be working ok, but we are getting relatively frequent audio dropouts in the middle of conversations. At times we can go for several minutes of conversation without a dropout, and at other times, it seems like it happens a lot more frequently. Sometimes it's just for a couple of tenths of a second and sometimes it's up to a few seconds long. So far I have had no luck in trying to track down the cause of this. Any thoughts anyone might have about what might be happening or where to look next would be appreciated. Some details about our config: Raspberry Pi 3 with DIAL RAT_RC1.img Repeater Builder RB-USB Rim Lite Interface Vertex VXR-7000 Repeater Metallic case for the Pi Modular connectors and Cat-7 cable for the interface with snap-on chokes at both ends Pi is connected to the local network via Wifi (We are prepared to move this to Ethernet, but need approval of the host to do so) Pi is connected to an external server via OpenVPN for collection of mgmt. statistics via SNMP Pi also runs Apache2 and Allmon2 Echolink is enabled (Node 746074) AllStarLink of course (Node 44011) Thanks in advance for any thoughts or help you might be able to give!

since you are using a metal case for the pi, you are attenuating the wifi rx / tx sensitivity and erp output.

Bill, Thanks for a complete description of your system, that helps a lot. I did see Bryan's response about Wifi. I would say it's possible. Maybe a sustained ping to see if it's dropping packets. Do the dropouts happen on inbound network transmissions or receiver input or both? Since you are running SNMP, how is the CPU load? Which channel driver are you running? 73, Steve N4IRS On 3/16/2017 1:06 PM, William Higgins wrote:

I'm wondering about the load Allmon2 is placing on the system. I know it is more efficient than the original Allmon, but I've never entertained the idea that the Pi3 could handle that much at once. Is anyone else running Allmon2 on their Pi? N5ZUA On 3/16/2017 12:17 PM, Steve Zingman wrote:

I run AllMon2 on a test node on the bench. I have not seen any issues. Just Basic DIAL RC1 and AllMon2. Steve On 3/16/2017 1:21 PM, Steve Agee wrote:

I run my node and allmon2 on a 6 core desktop so I can't comment on running it on a pi3. I do run my allstar hub on a pi3 with 10 nodes connected in to it and as high as 12 echolink users simultaneously with no trouble. Any time we have heard dropouts it has been in the remote end. All on cat6 gigabit connections back to the router, using cable modem with 150 down and 80 up. Sent from my iPhone

Speaking of Echolink, a couple of us have noticed something. Jim, KY2D, who I think might be on this list, can comment as well, since he uses a Pi. Likely I'll be moving my node from this cantankerous old (2009 vintage) netbook at some point to a Pi. Anyway. Echonlink. Seems if there are more than a couple or three connections into a node, outbound Echolink audio begins to sound "watery", for lack of a better word. Inbound audio, i.e. audio from everywhere through the node and on the air, sounds fine. Audio going out, from the node and over the Internet, whether from an RF station or another connection, has this sound. Only on Echolink audio, All Star audio always sounds great. This has been a thing on various incarnations of my nodes for years, I brought it up once before, but I figured eventually it was just one of those things. Sort of like the occasional crashes that take ASL off the air until it's restarted, which I think someone finally tracked down to the Echolink channel driver. Anyone else heard of this? -- Buddy Brannan, KB5ELV - Erie, PA Phone: 814-860-3194 Mobile: 814-431-0962 Email: buddy@brannan.name

I'm running Allmon2, one USB radio interface, two pseudo nodes, echolink, and a Broadcastify stream on a Pi 3. Solid as a rock. I think using Wifi is your problem. Justin NV8Q On 3/16/2017 12:21 PM, Steve Agee wrote:
