Portable Nodes
by David Osborn 24 Jul '13

24 Jul '13

Hi All, I was just wondering what people have deployed as a "node in a box" solution. I'm toying with building a portable node that can use either WiFi or 3G and which can be set-up in an arbitrary location as required. The general idea being aimed at emergency communications. So, what radios, what computer power (RTCM, perhaps?), what power arrangements? 73 David Osborn GD4HOZ

Telemetry Stanza
by Jeff Carrier 24 Jul '13

24 Jul '13

Here's a brain teaser for the guru's out there. I can specify different function stanzas for different nodes on the same box by naming them functions1234 and functions1235 and defining that in each node stanza but with the telemetry I can't do that. Is this by design or have I missed something? ex. [1234] functions=functions1234 telemetry=telemetry1234 [1235] functions=functions1235 telemetry=telemetry1235 73 de K0JSC

Is there a squelch tail eliminator setting for ACID in the full duplex mode?

The problem has been solved by re-installing ACID from scratch.

by Michael Hebert 23 Jul '13

23 Jul '13

All, I am setting up a voter system using the RTCM and GPS 18x LVC. Has anyone used the Garmin GPS 18x LVC to interface with the RTCM? Here is the pinout I have. want to make sure it is correct. RTCM GPS 18x LVC 7 PTT Out <-- Pulse Output 1 Yellow 13 5Vdc --> Vin 2 Red 8 Ground Ground 3 Black 6 Rx Data <-- TX Data 4 White 8 Ground Ground 5 Black 14 TX Data --> Rx Data 6 Red Thanks, Mike - KD5DFB

Sudden dropped packet problem on LAN
by Sam Skolfield 22 Jul '13

22 Jul '13

Hello Group, I have a test-bench voted configuration consisting of two RTCMs acting as receivers, one acting as a transmitter, and an app_rpt server. Everything was working great for days until suddenly, audio packets started to drop like flies. I had the "buflen" in the voter.conf file set to 200, and the TX buffer length in the RTCMS set for 1200, and made no changes whatsoever to the configuration. No matter what combination of buffer values I try, I can't seem to get the system to stop dropping packets. Mind you, all three RTCMS and the server are all connected to a common Verizon FIOS modem/4 port router. Any help is greatly appreciated. Thank you, Sam -- KJ6QFS Sam Skolfield

FLAT vs Preemphasized audio
by KJ6KO 22 Jul '13

22 Jul '13

We plan on interfacing with a Palomar repeater controller which uses FLAT audio in and out. It is designed strictly for disc audio in and output directly to a radio's modulator. Would the settings..... RXDEMOD = FLAT TXPRELIM = YES .... be correct to make sure the Palomar gets already pre-emphasized audio in and audio coming from the Palomar to the URI is de-emphasized in the URI before going out to the rest of the network? Many of the other nodes on the network are using MIC inputs and "Speaker" audio out. Would these commands go in the usbradio.conf file? If it is a DMK URI, would the same commands go in the simpleusb.conf file? Seems I remember setting something like this in the initial DMK setup...have only done one DMK. Not sure if final unit will be a DMK or some other URI. ...I know...a lot of questions!

New RTCM Feature - Duplex Mode 3 Support
by Tim Sawyer 22 Jul '13

22 Jul '13

Does delayed repeat audio bug you? Tired of hearing a bit of yourself after you unkey? Wish you could talk full duplex? Hate the echo chamber effect? Then we have the answer for you. Duplex mode 3 in app_rpt allows for "in-cabinet repeat" (where the radio hardware provides repeat audio) and app_rpt adds the hang time, courtesy tones, linking - all the things apt_rpt does sans repeat audio. Therefore no repeat audio delay. Cool, eh? This duplex mode has been in app_rpt for a while. Problem has been how to implement it. Duplex mode 3 support in the RTCM provides in-cabinet repeat functionality. Repeat audio loops through the RTCM and has almost zero delay because it does not have to traverse the network. The delay is not quite zero but it's plenty short enough to eliminate all of the above mentioned annoyances. Of course duplex mode 3 support can't be used with voting or simulcast. Upgrade instructions are here http://ohnosec.org/drupal/node/185 and here https://allstarlink.org/support.html#astupgrade. Normal caviots apply when upgrading to brand new firmware and software. Read the comments in voter.c. I'm very excited about this new feature and I think you will find it useful too. -- Tim :wq

Tones
by Robert Garcia 22 Jul '13

22 Jul '13

All, I am confused as to the tones I am hearing on the output of a repeater I am running with app_rpt. I hear the normal courtesy tone, but then right before the transmitter unkeys, I hear another tone, any ideas? Robert N5QM
