synchronizing transmitters for simulcast ( VCO Locking )
by Chuck Henderson 25 Feb '14

25 Feb '14

I changed the subject :) I don't think that the 1 PPS GPS will work for this. You need a GPSDO with a 10 MHZ output that then drives something like the micro-node.com PGCM that then generates the exact clock frequency that your transmitter needs. I do not know if they are still selling it or if there are similar products available from other sources. There is some information here. http://ohnosec.org/pipermail/app_rpt-users/2012-May/004463.html Let me know if you find what you need and get this working. I am also interested in simulcast but have been looking for an economical way to do it.

Thank you Jon Rorke for a well thought out reply. You hit the nail on the head and I haven't seen anything on this topic. That's why I asked. I have a Motorola MSF's and a Motorola MSR that have a VCO input and I was curious how to interface to it for simulcasting. I also have Motorola GPS receiver modules that plug into the repeaters. I sincerely apologize if some find this message thread as stupid, based on private emails, but not knowing where or who to ask I thought that this was the correct mailing list. Is there an easier way that as a noob with Allstar I just don't know about yet? If I read you correctly any GPS that provides a 1pps output provides the VCO locking in some form but is there a tutorial or a HOWTO that discusses this? I have a TKR-850 that I want to use as well and I'm not aware of a VCO input. If ya'll could just point me in the right direction I'd be much appreciative. I appreciate your helpful answer. Thank you. [Quote] uh,.... what? Seriously? (I know I'm working on cup #1 and it's not quite 6am... I had to read this a couple of times to 'really' see this question and it's just as silly, every time!)

Typically the external oscillator operates at some frequency like 16, 12.5 or 10 MHz but can be locked the GPS that puts out a 1 pps signal. Perhaps others can elaborate further. Jon VA3RQ

VCO Locking
by Wayne 25 Feb '14

25 Feb '14

I've been doing a lot of reading and I haven't come across anything that talks about VCO locking. How does Allstar lock the frequency of each transmitter? Thank you.

Re: [App_rpt-users] Web transceiver problems with only my node

Sounds like the port is not open to your node. Out bound connects will work but not in bound. Lee In a message dated 2/24/2014 8:36:10 P.M. Pacific Standard Time, mike(a)midnighteng.com writes: I am unable to connect to my own node (29283) using the allstarlink web transceiver. While I can use it to connect to other nodes, it should not be a java issue. And I can connect to other nodes from my node and I do have the node listed in rpt.conf enabling a connection. Since I am doing some heavy re-configing on that node, I decided to load a back-up copy of the conf to be sure I didn't to some weird typo by mistake, with no avail. I am presently on the same ip of the system but that has never been a issue in the past. Any Ideas ? ...mike/kb8jnm _______________________________________________ App_rpt-users mailing list App_rpt-users(a)ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users To unsubscribe from this list please visit http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users and scroll down to the bottom of the page.

MK808... anyone looking at this?
by n6gkj.cm98＠yahoo.com 24 Feb '14

24 Feb '14

Hey guys, Been playing with the MK808, 1.6 ghz dual core ARM9 processor, 1 GB ram, 2 USB2 ports, built-in WiFi. Small size, 3"x1.125"x.5". Comes stock with Android 4.1. I just installed PICUNTU Linux into one this weekend. There is enough CPU power to generate DATV MPEG2 transport streams captured from an external MPEG2 ENCODER. Makes me think it might be fast enough to encode our USB FOBS. Anyone playing with these great little computers? Sent from Yahoo Mail on Android

private nodes with dynamic IP
by Mihhail Jakovlev 24 Feb '14

24 Feb '14

Hi all, I am a new app_rpt user, I have a server with installed ACID, server have static IP. I have 3 assembled RTCM boards configured as voting repeater, it works fine. One RTCM can work as simplex node too. I was compiled app_rpt for Raspberry pi with SimpleUSB, it works, but I have question: How I can connect 2 maybe 3 or more) PC based "slave" nodes (endnodes with radio connected) to "master" server, if only "master" server have a static IP, and all endnodes use dynamic? Two nodes in local network with static IP works fine All my nodes a private system(s), not in Allstar network. Master server have static IP, and all endnodes (PC based and RTCMs have dynamic addresses) Thanks! Mihhail Jakovlev ES1BIS

Tecnology net on node #27684
by ea8ee 23 Feb '14

23 Feb '14

on February 23rd @ 1*6:00 UTC* a group of friends from the hispanic community from all over the world will start for the first time on reflector XRF007B I am inviting you if you have a change to stop by reflector XRF007B and check in. The purpose of that net would be to integrate the hispanic world into technology DMR/MOTOTRBO and different uses that hams operators are doing in countries like Mexico (XE3RA) and Spain (EA5HJX) and much more all related to digital communication This net will be accessible on Ref XRF007B, ED8ZAB B IRLP:EXP0063, ALLSTAR:27684 Echolink: on ED8ZAR-R node #1017. This net would be in the beautiful *Spanish* language for those of you that use it. Thanks in advance for your visit and we'll heard each other on reflector XRF007B on 02/23/2014

Simpleusb question
by Doug Crompton 23 Feb '14

23 Feb '14

In the note - http://ohnosec.org/drupal/node/193 In configuration of simpleusb the following line is mentioned - touch /etc/init.d/simpleusb I presume this is just to put a zero length file marker at this location? Is this needed? What references this? Does simple USB need to be a service in any derivative of app_rpt - zaptel/dahdi ? 73 Doug WA3DSP http://www.crompton.com/hamradio
