RTCM GPS sentence
by James Cizek 04 Apr '16

04 Apr '16

HI all, Does anyone know which GPS sentence(s) the micro-node RTCM is looking for? I am working on adapting some commercial GPS units that originally provided timing for cellular sites and I suspect that my remaining issue is that it's not outputting the sentence the RTCM is looking for. If anyone knows which one (or ones) it's expecting, it would be greatly appreciated information! My unit is currently spitting out $GPGGA but even after a valid fix is achieved, the RTCM remains in the state "GPS is active, waiting for lock" Thanks James KI0KN

rxdemod=speaker not working for remote base
by Skyler F 03 Apr '16

03 Apr '16

I just set up a remote base with deemphasized audio, not discriminator. On usbradio.conf when I set up rxdemod=flat, the audio sounds very bassy coming from my remote base, so I changed it to rxdemod=speaker. I restarted asterisk, and now no audio came from the radio, just a dead carrier, even when I turned the rx level to 999 in usbradio.conf. 73 Skyler _____________________________________ Here is my usbradio.conf file: [general] [usb] hdwtype=0 rxboost=1 txboost=0 rxctcssrelax=1 txctcssdefault=250.3 ;rxctcssfreqs=100 ;txctcssfreqs=100 ;rxctcssoverride=1 carrierfrom=usb ctcssfrom=usb rxdemod=speaker !!!I get audio when this is set to flat, but nothing on speaker!!! txprelim=no txlimonly=no txtoctype=phase txmixa=composite txmixb=no invertptt=0 duplex=1 rxondelay=1 rxsquelchdelay=25 rxnoisefiltype=0 eeprom=0 ;gpio=out1 gpio1 = out1 ; in, out0 or out1 gpio2 = out1 gpio4 = in ; in, out0 or out1

Translating voice messages in French : where's the "to" ?
by Toussaint OTTAVI 03 Apr '16

03 Apr '16

Hi, I'm translating the voice messages, so that they are in French, and with "real names". f/ex, instead of "Node 1234 connected to node 5678", I want to hear : "Ajaccio VHF connecte a hub voip" I found the corresponding audio files in /var/lib/asterisk/sounds/rpt, and I recorded them in French. But I still hear the "to" in English, and I didn't find any file named "to.ulaw" or "to.gsm". So, where's the "to" ? ;-)

Asterisk Died With Code 1
by Steve Schulze 03 Apr '16

03 Apr '16

On of my nodes lost a motherboard a couple of weeks ago and I finally got around to getting a new (refurbed) PC for it. Now I am running into the problem with Zaptel. I keep getting the: MPG123: no process killed Asterisk ended with exit status 1 Asterisk died with code 1 etc, etc... Looking at the past discussions on this, I have not found that anyone has come up with a resolve for this. Has anyone come across this lately and were you able to resolve it? Fresh install on an HP DC7800N with 4GB ram and a Intel Core2 vPro processor.

Hamtronics receiver issue with AllStar RTCM
by Skyler F 03 Apr '16

03 Apr '16

For a voter project, we got the hamtronics VHF receiver pretuned to the repeaters input frequency. The idea is to use hamtronics receivers for every voted receive site for equivalent audio characteristics. http://www.hamtronics.com/r303.htm When hooked up to the discriminator on the hamtronics board, I could not get the RTCM to calibrate squelch. It usually told me the audio was too low weather the RX level was bumped up or down. I then hooked it up to a motorola SM50 and it calibrated shortly after adjusting RX levels. So... I hooked a cheap sound card up to audacity, and took a look at the spectrum of each receiver. The hamtronics obviously looks like it lacks high frequency noise on the discriminator output. Here is the SM50 discriminator out: amsatnet.info/SM50.png Here is the hamtronics discriminator out: amsatnet.info/HAMTRONICS.png Here is an audio sample comparing them (you can probably guess which radio is first): amsatnet.info/Sm50_hamtron_DISC.wav Does anybody else have experience with hamtronics receivers? Thanks, Skyler KD0WHB

How to add chan_rtpdir.c to DIAL
by Michael J. Wolthuis 03 Apr '16

03 Apr '16

I am finally replacing a very old install of ACID at a HUB site with DIAL. This site does have some ties though to rtpDir_tm which is older, but still fun and working… I can’t seem to get chan_rtpdir.c to compile into Asterisk. I put it in the channels folder and recompiled, but it acts like it didn’t add it / compile it in.

Impedance matters. That the output/source circuit and/or the input/load circuit mis-match alters frequency response is sloppy implementation. Unless you have complete control over system components design and implementation, it is prudent for audio-take-off/recipients/input circuits to not terminate at whatever unknown source impedance, but instead bridge-tap at 10k ohms. The outputs you have design/implementation control over can be whatever you want, but convention is typically 600 ohms, 0 dB max standard level from 300-3000 Hz. Squelch noise detection from an Rx detector may begin at 4 KHz (marginally low) or typically 6 KHz for white noise. The Motorola Micor SQ chips and not so obvious app notes indicate/allow a higher frequency detection limit at the base/repeater (6KHz) than the mobile (more subject to flutter) of 4KHz. All that yadda aside... folks need to learn that audio connections between unknown gear might best be bridging (10k ohms) to get audio, and should provide/tolerate 600 Ohms to give audio. If even bridging affects the frequency response the source audio point is questionably engineered/implemented. Impedance matters.

How to change the Default EchoLink text
by Skyler F 01 Apr '16

01 Apr '16

Hi everyone, I've wanted to change the default EchoLink text for a while. I finally found where EchoLink stores it's "Welcome to AllStar Node XXXXX EchoLink Node XXXXXX Systems Linked" prompt. The text can be found and modified in: /usr/src/utils/astsrc/asterisk/channels/chan_echolink.c Use the nano Control+W to find the text "Welcome to AllStar" Example, to add a new line before the status display, I changed this line *"oNDATA\rWelcome to Allstar Node %s\r" to* *"oNDATA\rTEXT HERE FIRST\rWelcome to Allstar Node %s\r"* (Directory may be different depending on distro: this is Jeremy's W0JRL for the Raspberry pi 2 Then in the /usr/src/utils/astsrc/asterisk You have to run ./configure make menuselect.makeopts make make install asterisk-restart -- Skyler Fennell amsatnet.info KDØWHB electricity440(a)gmail.com

Scratchy audio on some transmissions
by Skyler F 31 Mar '16

31 Mar '16

On my 900MHz node, I am having problems where the "repeat only" and various transmissions sound clipped and scratchy. I turned my audio down the the lowest setting (so I had to really crank my receivers audio) and even the small, barely deviated amount of audio that came out was scratchy when Allison announced "repeat only". Has anybody had this issue before? The clipped audio only seems to occur on transmissions with a lot of punch, and is fine for both. Both adjusting the deviation on the radio and turning my TX audio down to a bare minimum does not seem to do the trick. Audio levels is not a problem, however. We tested it on a service monitor and got the deviation fine with the test tone. Thanks Skyler
