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
