CM108 dongle
by George Csahanin 18 Sep '09

DEalExtreme still has 'em at $6.35 each in quantities over 3. I think that includes shipping. I bought five or six a few months ago, and it took a few weeks, but they were CHEAP. http://www.dealextreme.com/details.dx/sku.21812 George J Csahanin W2DB

Help with IRLP Experimental Refector Configuration
by John (WB5NFC) 17 Sep '09

17 Sep '09

New iso is working fine with Echolink, but I'm having problems with IRLP... Cannot get an IRLP node to connect to my experimental reflector. The IRLP station hears a connect message, but I don't hear a thing. The node trying to connect is properly configured to connect to exp reflectors. Both irlphosts and exp-x-reference are updating. I have verified that the dyndns IP on file for my experimental node is correct... CLI output: [Sep 13 13:52:33] NOTICE[2419]: chan_irlp.c:1125 irlp_reader: irlp node attempted connect from 74.194.177.242 with no node info irlp.conf: [general] node=exp0012 call=wb5nfc rtcptimeout=10 localispeakerport=2174 radmode=no audioport=2074 context=radio-secure astnode=2347 Suggestions on how to troubleshoot greatly appreciated...

[morse] stanza
by Eric Tichansky 17 Sep '09

17 Sep '09

Is there a node stanza parameter for setting a custom morse stanza mapping? The documentation online seems to suggest this, but there does not appear to be any such parameter in the app-rpt source. 73 - eric - no3m

That's why I suggested waiting for the release. The gist of it is that you are going to need chan_usbradio.c and everything in the xpmr directory as well. Please understand that because this is a manual change you need to proceed at your own risk; none of this code has been regressed against older versions. I'm not in a position right now to give intensive help if something goes wrong. Steve WA6ZFT

Kerchunk filter or equivalent of pulseback timer?
by Ramesh Dhami (VA3UV) 16 Sep '09

16 Sep '09

Hi All; One of the local repeaters is connecting to the VE3TNK HUB (#2200) using an off-site link radio (since there's no IP at the repeater site). Unfortunately, the analog repeater controller can not be set for zero hang time, and therefore the short hang time is being exposed to the hub and all of the downstream nodes. Is there a kerchunk filter or the equivalent of a pulseback timer (as there is in IRLP) to compensate (filter out) such kerchunks? Thanks! Ramesh.

Re: [App_rpt-users] Busy Lockout on simplex node

This is by design. To do otherwise violates the rules here in the US, although I am curious as to why you want to do this? You also might try duplex=0 and linktolink=yes in rpt.conf. For more info on duplex modes, look here: http://app-rpt.qrvc.com/node/84 Steve WA6ZFT > > From: "Adrian Caldieraro" <adrian(a)choicecomm.com.au> > Date: 2009/09/16 Wed AM 08:35:24 PDT > To: <app_rpt-users(a)qrvc.com> > Subject: [App_rpt-users] Busy Lockout on simplex node > > I have just recently got my system up and running and for testing I am using > a simplex radio, what I have found is that I cannot PTT the radio whilst it > has a busy signal.

Busy Lockout on simplex node
by Adrian Caldieraro 16 Sep '09

16 Sep '09

I have just recently got my system up and running and for testing I am using a simplex radio, what I have found is that I cannot PTT the radio whilst it has a busy signal. Is there a way that I can override the busy channel lockout?

Longley Rice Online Prediction Tool

Longley Rice Online tool: http://lrcov.crc.ca/cov.php?lang=en I also use Radio Mobile by VE2DBE: http://www.cplus.org/rmw/english1.html They do agree with each other. I use radio mobile professionally to do path studies, STL links, and to figure out azimuths for some of our remote broadcasts. You can make some great maps of your coverage. -- Don Russell, CBRE W9DRR ARRL OES, Technical Specialist Winnebago County AEC http://www.socialengineer.us --

Info for New users, working set of configs, and some scripts.
by Don Russell 15 Sep '09

15 Sep '09

Since we have a group of new users around.I Just wanted to share a few little helpers I picked up and some working configs to compare with. Check out the source of app_rpt.c lots of help at the top, most if not all of the commands are documented there. It helped me a lot when I was first getting started. The included tarball has my complete working config files - a couple passwords and pincodes, my crontab, some custom scripts, and the weather scripts I modified from IRLP. W0ANM and Randy KC6HUR wrote them. I hacked them up to work with asterisk. and the Cepstral voice William. I also used William to replace a bunch of asterisk words to keep the repeater audio consistent. No offense to Jim, Steve, and Allison. (Speaking of Allison, I met her at Astricon one year, Freaked me out, I didn't know what she looked like, the door to the elevator opened, this chick at the door said something like "hello, going down?" I started looking around at the speakers in the elevator trying to figure out how someone got Allison to do voice over work for the elevator. then it hit me.. SHE was Allison....LOL) I also included some scripts I use for changing how the repeater functions. they change hang times, Courtesy tones, ID's, and gets the node connected up for weather events. I also have a restore to normal function. It does copy around the /etc/asterisk/rpt.conf so be careful in playing with them. backups are important. As far as my hardware: I am using de-emphasized audio (speaker) and have a COR signal from the receiver going to the FOB. In addition to the caps, I also used 1:1 transformers on the RX/TX audio lines to kill any ground loops. I also put in some ferrite beads on the audio lines, made sure everything was properly grounded, including the usb connector on the fob, that solved a lot of ills with ground loops(hum) on my end. I did change most of the values to make things suit the audio levels I needed. The original fob design was designed for Motorla or other Radios with very hot discriminator audio. My GE wasn't quite that hot, and the ICOM I used for a while was even lower. So feel free to play with them or just put in a pot and trim around at will. My current receiver is a Motorola Astro Saber running in Dual mode IMBE NAC 294/Analog PL 97.4. I took the audio from the speaker mic output through the 1:1, I also took one side of the audio line w/ a pull 2k pull down resistor to the COR pin. works like a charm. A lot of Motorola radios only power on the audio amp when there is proper PL/NAC. both sides of the amp have a floating DC bias that changes when the amp powers on, floating when off, +4.7 when on. I little trick I got from Jim WB6NIL... My previous receiver was an old Uniden that I tapped raw Discriminator and fed the fob via the 1:1 transformer. That also worked pretty good with the DSP mode. Until the person I got the radio from played Indian giver. The transmitter is nothing fancy.. just an old Kenwood G707 mobile being fed from the packet jack (ps2 type) on the back. I do have an Industrial mega CFM fan blowing across the back of the transmitter to keep it cool. So far its doing just fine. My system is not very heavy in traffic. Eventually I want to replace it with something more robust like a spectra or X9000 syntor. If I can get my hands on one cheap. Hope they are useful to some of you. -- Don Russell, CBRE W9DRR ARRL OES, Technical Specialist Winnebago County AEC http://www.socialengineer.us --
