Domain setup failure
by Tower DIVA 03 Feb '16

03 Feb '16

Have RPi setup and can SSH into and work on it. It will not ping any domains. I can ping IP's all day long, but if I try to ping yahoo.com, or register.allstarlink.org, or google.com I get unknown host. On the all node list the node is green boxed but the online list shows it as offline. help? I am pulling hair out here. Keri

Re: [App_rpt-users] Controlling radio with a knob

That depends on a number of things. Unless you are planning on just emulating pulses for the microphone up down buttons. If the radio supports some sort of remote tuning (CAT / CIV etc) then it can be addressed digitally though that port. There is an excellent open source (Ham Radio Control Libraries) called hamlib that supports a number of radios that have native remote tuning support. As for the remote knob, you'd likely want a digital(coded) rotary switch. Know that you know what the knob is called you can research how it translates its position to a digitally coded word that could easily be read in to GPIO/etc. On the other end you'd need to take that word and convert it back to a properly formatted CIV/CAT command, or series of microphone up down puleses. etc. Another possibility that is not as well documented for radio that don't support native CIV/CAT tuning is to look into how the Swedish Remote Rig intercepts and emulates TTL signaling on radios that have remote mounting. I have always admired the somewhat pricey thing and have been meaning to try and serial sniff my own radio to possibly create my own. The ARRL has an okay book sort of on this topic called "Remote Operating for Amateur Radio" While its not real technical, you'd lkely pick up a few things from it. I Hopefully this gives you a good starting place for things to further read up on. Good luck. I do believe this is an area of the hobby that needs more attention (with restrictive antenna ordinances for many), so please consider sharing anything you discover. 73 Steve, KB9MWR > Is there any way to use GPIO to tell a radio with a turning knob which > channel to switch to? > > Want to use a Kenwood TK-805D for a remote base (this is a 16 channel > radio), but the problem is that I don't have a way to simulate a knob spin. > Does anybody know how these knobs work, and without a mechanical servo how > to tell the radio to switch channels? > > 73 > Skyler KD0WHB

Incoming echolink user timeout after twenty seconds
by Larry da Ponte 02 Feb '16

02 Feb '16

On a DIAL AllStar node with EchoLink configured, an incoming Echolink user's transmit is interrupted after twenty seconds on every transmission. A local key-up resets the timer and the remote station's transmission resumes. At the time of disconnect I see this in the verbose asterisk console output every time: -- <DAHDI/pseudo-960886400> Playing 'rpt/node' (language 'en') -- <DAHDI/pseudo-960886400> Playing 'digits/4' (language 'en') -- <DAHDI/pseudo-960886400> Playing 'digits/2' (language 'en') -- <DAHDI/pseudo-960886400> Playing 'digits/2' (language 'en') -- <DAHDI/pseudo-960886400> Playing 'digits/6' (language 'en') -- <DAHDI/pseudo-960886400> Playing 'digits/9' (language 'en') -- <DAHDI/pseudo-960886400> Playing 'rpt/timeout' (language 'en') -- Hungup 'DAHDI/pseudo-960886400' We've been unable to locate the setting (if there is one) that would cause DAHDI to play rpt/timeout. Where should we be looking? Thanks Larry HB9EYQ

Controlling radio with a knob
by Skyler F 01 Feb '16

01 Feb '16

Is there any way to use GPIO to tell a radio with a turning knob which channel to switch to? Want to use a Kenwood TK-805D for a remote base (this is a 16 channel radio), but the problem is that I don't have a way to simulate a knob spin. Does anybody know how these knobs work, and without a mechanical servo how to tell the radio to switch channels? 73 Skyler KD0WHB

Audio not passed when on usbinvert?
by Skyler F 31 Jan '16

31 Jan '16

I am really confused right now. I am using a URI with some kenwood TK-941 radios for a repeater. I am using De-emphasized audio. Here is what is happening. I am using usbradio. I set the rxctcssoverride to 1 for testing. I turn the squelch off in the radio, and put carrier from to DSP. (Yes, I know, this is the wrong type of audio for DSP). I go to radio tune menu, set the squelch to zero, and I hear the white noise being repeated perfectly. Now, I set the carrier from to USB. When I turn the squelch off on the radio, the red light enables, and the transmitter transmits. However ... There is no white noise being repeated, just a plain carrier. What??? I tried this on the computer as well as the raspberry pi. My audio input is on the left channel. Even when I set the input volume to 999, I still don't hear anything, just a carrier. So I know -Speaker Audio is coming into the computer through the URI -When DSP is enabled, and the squelch is set to zero both on the computer and the radio, audio is repeated -COR is set up because the transmitter will key up when the receiver gets a signal So now I need to figure out what is preventing the audio from rebroadcast when the input is set to usbinvert. 73 Skyler KD0WHB

Garmin GPS18x no longer compatible with RTCM
by James Cizek 28 Jan '16

28 Jan '16

Hi folks, Wanted to get this out to you before anyone else bought one thinking they would work (since this model is specifically called out in the RTCM docs). When using a GPS with a Micro-node RTCM for voting, you need to find one that has a 5 volt Pulse-per-second output. The Garmin lines that is recommended (GPS 18X, 18X lvc, etc...) NO LONGER do this! This is what I got back from Garmin: Mr. Cizek, I was just told there was a design change with the GPS 18x LVC. The PPS signal voltage is now 3V. This was something we were not told until today. We will be making the changes to the online Technical Specifications to reflect this change. I do apologize for the inconvenience. This was a change we were not informed of. So this line of GPS's will *NOT* work with an RTCM any longer. Talking to Mark at Micro-node, there is a voltage divider in the RTCM dropping the 5 volt to 3.3 volt to be compatible with the CPU. With only 3 volts on the incoming line, there isn't enough making it to the CPU to trigger a state change and you will get "PPS Timeout" errors and be unable to achieve GPS lock. I am not sure what kind of timing skew a level converter would introduce, so it's probably a better bet to just get a GPS that has a 5 volt line (Trimble Thunderbolt or the similar). There may be a possibility of removing or modifying the voltage divider inside as well, but without schematics, and unless you have SMD capable gear, it's unlikely that that is a good solution. Just wanted to let folks know so they don't repeat the brain damage I just went through figuring this out :) 73 James KI0KN

Question regarding echolink setup
by Greg Mohr 26 Jan '16

26 Jan '16

I am new to Allstar and am attempting to get the echolink node ID/PSWD combination to work. It works as I can bring up Echolink in sysop mode under the profile for the repeater. I believe I configured it correctly in the setup on the Allstarlink website and in the setup on the local node as well. I am not sure where to look or what else I might need to do to get the echolink aspect up and running, any direction would be great. Thanks, 73, Greg, W2GCM
