i2s audio interfacing for RPi et al
by Steve Wright 17 Mar '17

17 Mar '17

Whatever happened about the move to ALSA? It seems with ALSA, some GPIO and these new 8ch i2s boards, all the work would be done. Maybe even some S/PDIF might help keep RF out of things and ditch some DC current loops. http://www.audioinjector.net/rpi-octo-hat

Re: [App_rpt-users] RPi 3 controller problem (Steve Zingman)

I haven't figured out how to do replies when I only get the digest in gmail. Anyway, Steve, re this: >I don't THINK the receiver dropout and the EchoLink inbound are related. >The problem COULD be radio_relax. (The DTMF decoder is falseing) Though >I wonder about the duration of the dropout. How did you set receive levels? > >Steve I was monitoring the Asterisk console this morning during a QSO on the repeater and DID see a number of DTMF false messages. They were all just a matter of 10-100 milliseconds, but there did seem to be a disruption of the audio when they came along. I didn't tie the two together in my head because there didn't seem to be a one to one correlation, if you get my drift. I set the receive levels using radio-tune-menu. It was all done onsite at the repeater with MINIMAL equipment (an HT.) I have since done some tuning on it (especially the receive levels) from home during typical QSOs. Bill

Let's see if I can answer the questions that have been asked: Steve Zingman: I believe the dropouts are primarily on receiver input. I've not noticed them on Echolink inbound traffic. The CPU load is minimal. Generally under 2% used. We are using USB_RADIO without DSP (I couldn't make that work initially for some reason.) Steve Agee: As I said, the CPU load is minimal. There might be tiny momentary peaks, but there is no sustained load on the processor. Neil K8it: The wireless connectivity doesn't "seem" to be a problem. The router to which it is connected is only about 4 ft. away. Thank you all for the suggestions. Would love to hear any other ideas you have! Bill Higgins N0NOE KC0DBS - 44011 N0NOE - 43758

That's probably on par with what they use. In the last 12 days one of my RTCM's recieved 476 mb of data and transmitted 1623 mb of data. At idle it's transmitting between 560-1072 bps and receiving 768 bps de K0JSC On Thu, Mar 16, 2017 at 10:00 AM, < app_rpt-users-request(a)lists.allstarlink.org> wrote: > Send App_rpt-users mailing list submissions to > app_rpt-users(a)lists.allstarlink.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_ > rpt-users > or, via email, send a message with subject or body 'help' to > app_rpt-users-request(a)lists.allstarlink.org > > You can reach the person managing the list at > app_rpt-users-owner(a)lists.allstarlink.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of App_rpt-users digest..." > > This site is dedicated to the memory of Jim Dixon WB6NIL > > > Today's Topics: > > 1.

Allstar RTCM unit bandwidth usage
by Bradlington 15 Mar '17

15 Mar '17

Good day I am new to ALLSTAR and we have recently integrated Allstar RTCM unit into our clubs local repeater. We are using a 3G dongal for internet connectivity -through an ethernet bridge feeding out to both the DMR and Allstar RTCM units. The data usage has dramatically increased since the inclusion of ALLstar . Does anyone have an accurate table of data consumption for various duty cycles per day so we can see if this is normal or if there is another reason for presumed excessive data consumption . On average the DMR alone used 70 Meg per day - since the addition of allstar RTCM , combined it has gone up to approx 220 Meg /day. Kind regards Bradley Glen zs5bg

Dial
by Ryan Gross 15 Mar '17

15 Mar '17

Hi, I have a RP2 running DIAL and works great tied into a Micor Base Station. The question I have is I want to set up some crons to runs macros at top of hour like ID and time. but the kicker is I am using main audio as primary and injecting aux audio this care PL direct into with Repeter builder rim or URI pin 23 Right as tone out. What I am looking is how to set up the hourly Id's not to transmit PL. and a way to setup Id's similar to the methods used on Scom 7330. Thus far I have not found a solution.

Can I "hook" app_rpt events?
by William Higgins 15 Mar '17

15 Mar '17

I may have overlooked this in the research I've done so far, but I thought I would ask here. Is there a way to "hook" an event in app_rpt? For example, I'd like to run a script every time my repeater ids. Is there a way to do that? Executing a shell script or hitting a web service would be ideal. I might also want to perform other actions based on other events that app_rpt performs. It seems like this might be a reasonable feature request if it doesn't already exist. Thanks in advance for any guidance y'all have on this. I'm still relatively new to AllStar Link and am still learning. Bill Higgins N0NOE KC0DBS Repeater on Node 44011 N0NOE Simplex on Node 43758

Simulcasting with RTCM/voter
by Hayden Honeywood 14 Mar '17

Really interesting thread so far. Tim I was getting those figures from an article I read here - http://urgentcomm.com/networks_and_systems/mag/designing_simulcast_networks… "Analog FM systems on 25 kHz channels typically can withstand two relatively strong, equal amplitude signals with up to 150 microseconds relative delay before speech is unintelligible, according to Garry C. Hess in *Land-Mobile Radio System Engineering"* I have used radio mobile quite a lot. It might be time to ascertain my coverage. The only gripe I have with Radio Mobile is that it overestimates at low band VHF by default. UHF coverages are pretty accurate in my opinion. I've also used Splat, and still use Splat to overlay onto Google Earth. Do you change the strong signal margin on one site in Radio Mobile to 0dB/20dB for the 10dB difference, then plot the two together? Hayden
