Firmware version 1.50 I guess I am not familiar with a "Chuck squelch patch" so am guessing that I am not running it! Can you help point me to information? Thanks!

And are you running firmware with the "Chuck Squelch" patch enabled? Lee

Squelch issue with RTCM and Kenwood

Hi James, As Lee said, load Chuck squelch and see how it goes. I had similar issues with mine (although I'm running the VOTER board). The RSSI meter would jump around all over the place. I also had to find a suitable location for the discriminator on my radio. In my case the pin labelled "discriminator" had some high pass filtering applied. The delay seems inherent in the RTCM/voter. I've tested over a LAN with a latency of <1ms and I still hear the last syllable of my last word when unkeying. This is with the RX buffer set at 120ms and the TX buffer at 60ms (so is that 180ms total). There must be over a half second delay elsewhere within the processing of audio that is added? Hayden

Is anyone using the Nextion Display for Allstarlink? If so, can you share your .hmi and the .tft files? Thanks, David KE6UPI

David, I didn't go into any detail but I have ATT UVerse. 2 pairs bonded and supposed 50Mb service, won't stay up for over a day. 1o service calls, they now say I need to drop to 32Mb, but the tech here this morning spotted a fault on "pair 2", which I've been telling them for 2 months. When it goes out pair 1 will come back fast with good noise margin, pair 2 struggles to get over a 0 db noise margin. She finally figured there is a short, intermittent, 75 feet from my pedestal, and its not on my side, its theirs. So outside wire crew coming to make some kind of connection up the street. It is running right now on pair 1 just fine. Right now my node is up and connected to W8VT in WV GeorgeC Allstar 2360 On 5/1/2017 11:00 AM, app_rpt-users-request(a)lists.allstarlink.org wrote: > Subject: > Re: [App_rpt-users] OT: ISP's > From: > David Shaw <shawpbx(a)gmail.com> > Date: > 5/1/2017 10:55 AM > > To: > Users of Asterisk app_rpt <app_rpt-users(a)lists.allstarlink.org> > > > AT&T Home (DSL), Dish Network or Wireless?

Hi folks. I may have to change from AT&T to Charter/Spectrum cable ISP. Anybody use them or know of any restrictions/limitations as far as Allstar is concerned?

Squelch issue with RTCM and Kenwood
by James Cizek 01 May '17

01 May '17

Hi folks, After dozens of trips to the mountains to get all the physical infrastructure upgraded and changed out to Allstar/RTCM, I am finally getting back to some little cleanup items. I've written before on the "squelch crash" issue, and found that once things were tuned up, no one really had any issues with it. We are having severe issues with it and I am trying to narrow it down. All sites consist of: Kenwood TKR750 (or 850 if UHF) repeater. RTCM Local on-site PC (micro itx PC with Intel Atom D2500 1.8Ghz Dual core CPU and 2GB ram) Local mikrotik router (RB2011 in most cases, some CRS125) Except for voters, all repeaters are using the DIAL box plugged into the same local router as the RTCMs (ie, just about zero network latency) Some sites have 1 repeater, some 2, the biggest site has 2 repeaters and 2 voters. Squelch and Diode calibration was done per RTCM manual RX level set per manual TX level set by generating 1khz tone with "cop 4" command in asterisk and adjusting output for 3khz on service monitor. All sites are running DIAL, everything is private node numbers and private IP space (no network congestion since we aren't sharing with anything else). The RTCM is using external CTCSS input from the Kenwood on pin 24 of the AUX connector and pin 24 is set to "TOR". The squelch crash is usually only a problem on weak signals, or very short (kerchunk) bursts. I have included a short video showing the problem on a test bench. The video shows the transmit/receive LED on the HT, and the LEDs on the RTCM. It's very clear that the receive signal is gone and CTCSS has dropped while the transmitter is still held on to transmit the squelch crash. The video shows a clean transmission, followed by 2 crashes simulated with a double "kerchunk". The mountain top repeaters squelch crashes are upwards of 1 full second of audio after the incoming transmission has stopped. I am wondering if I don't have enough CPU on the DIAL box? Is it possible that I just don't have enough to do the DSP processing fast enough? Any tips after seeing the video much appreciated. Thanks!!

ohnosec vs. allstarlink
by Alan Crosswell 01 May '17

I noticed that some of the content from ohnosec drupal has not been mirrored to allstarlink. For example HowTo's/Using URI's/Adjusting Audio Levels is missing <http://docs.allstarlink.org/drupal/node/140>. What's the deal here? I get the impression that the intent is to migrated from ohnosec to allstarlink but it's incomplete? 73 de N2YGK
