Radio Control was referenced as "Auxiliary Service". Per Part 97 : Sec. 97.201 Auxiliary station ------------------------------ (a) Any amateur station licensed to a holder of a Technician, General, Advanced or Amateur Extra Class operator license may be an auxiliary station. A holder of a Technician, General, Advanced or Amateur Extra Class operator license may be the control operator of an auxiliary station, subject to the privileges of the class of operator license held. (b) An auxiliary station may transmit only on the 2 m and shorter wavelength bands, except the 144.0–144.5 MHz, 145.8–146.0 MHz, 219–220 MHz, 222.00–222.15 MHz, 431–433 MHz, and 435–438 MHz segments. So 2 meters and above now. 73, Duane KA1LM

Getting details of AllStar Node from the Node ID
by 2E0SIP 25 Apr '18

25 Apr '18

Hi All, Is there an 'API' (Either on the local node or the web) for getting info on an individual AllStar node, from the node number? E.G Call Sign / Location etc Or, a list in CSV / JSON format? There's a list here - https://allstarlink.org/nodelist.php But from experience, parsing HTML tables is a pain. Thanks Matthew 2E0SIP

RPi Gpio
by KD2NFC, Joe Puma 25 Apr '18

25 Apr '18

Greetings, I’m new to the group here and have some questions regarding All-Star link. I have a raspberry pi already set up with an HT radio (baofeng) and I was using svxlink node. I already have the radio wired up to use the GPIO on the raspberry pi for a PTT and COR. I use a USB dongle for audio and I am not sure if it is the same one that is used to modify and tap the GPIO pins, But I was trying to find a way to use the GPIO from the raspberry pi instead, since it’s already configured that way and works with SVXlink. I have been finding information on the Internet that suggests that the All-Star link software can be configured to use the RPI GPIO pins but haven’t found any solid documentation to do so. I was going to jump back in and look at the configuration files to see if there are any clues there but if someone has done this already can you please clue me in how I can use GPIO from the raspberry pi. You can check some of my radio projects here http://instagram.com/KD2NFC Best Joe KD2NFC Sent from my iPad

Can't link to AWS hosted AllStar Hub - Solved
by Bob Meyer 25 Apr '18

25 Apr '18

In short: the problem was operator error. I had tried earlier to put two servers/nodes on the same LAN, and then decided to move one of the servers and its node to a virtual PC on Amazons AWS. I neglected to properly edit the config files after the move. We have since had 4 nodes simultaneously connect to the node on AWS. Thanks to Steve Z and the others for their time and suggestions!

Many thanks to those that responded. I didn't know about the tcpdump cmd, so thanks for the tip. I am indeed receiving udp 4569 traffic on the AWS-based node. I also added the 5060 udp port, and tried tcpdump 'udp 5060' but saw no traffic on that port. I don't think SIP is enabled by default on AllStar, and had seen no recommendations in the setup info, but thought it worth a try. An additional bit of info: When the connection from a radio-based node fails, the CLI on it shows a message about "Auto-congesting call due to slow response". The same radio-based node can connect to other nodes, such as 2000, with no problem. I assume now, that the firewall/port configuration is not the issue, but something else. I see there are several wait timings in the rpt.conf file. I not sure if one of those is related to giving up too soon when the connection is attempted. Any other thoughts as to what might be going on? Has anyone been successful on another VPS?

We had a Motorola MSR-2000 lock on continuous due to a dropping-resistance 2N7000 FET PTT switch. It drifted low enough to keep the TX locked on but too high to allow the hardware TOT card to see the "keying" and drop the transmitter. The FET was on a homebrew FOB with 2N7000 PTT switch. Really glad we have a continuous-duty RFPA! 73, Duane KA1LM 42996

WinSCP root login fail

After setting PermitRootLogin to yes, and re-booting, I can login via the local keyboard, but WinSCP responds with ' access denied '. The ' Authentication stanza ' in sshd_config is: #LoginGraceTime 2m #PermitRootLogin yes #StrictModes yes #MaxAuthTries 6 #MaxSessions 10 I do see the SSH service running when I do a service --status-all If I try to install OpenSSH, it responds with ' client is already newest version Len WB2HKK

ASL Updates
by Steve Zingman 23 Apr '18

23 Apr '18

I have pushed the updates to the scripting used to support ASL on all platforms. If you are running a Raspberry Pi: sudo apt-mark hold raspberrypi-kernel-headers raspberrypi-kernel (If you have not already done this. Will not hurt to do it again.) sudo apt-get update sudo apt-get upgrade -y sudo apt-get update sudo reboot This will upgrade you to the latest AllStarLink, supporting scripts and Raspbian. All other platforms: sudo apt-get update sudo apt-get upgrade -y sudo apt-get update sudo reboot 73, Steve N4IRS
