Macros?
by John Bettasso 17 Jul '09

17 Jul '09

What is the magic to get macros to work? In my functions sections I have the following: 83=macro,1 In my macro's section I have: 1=*81*82 but when I type 'rpt fun 1999 *83' in the CLI nothing happens. but when I type 'rpt fun 1999 *81*82' in the CLI it executes both of those commands. Thanks, John

connect greeting

this may have been asked before (and I may have been the one who asked), but how can I go about getting a custom connect greeting to play instead of the standard n o d e 2 1 6 5 , etc?

Ok, now I feel stupid, lol. After looking at the board a little more I realized it was a simple mistake I made. In the pdf file it shows the RX Audio wire going to the mic connector soldered to the center pin closest to the edge of the board. On the adapter I have, because it's all surface mount, there is a connection on both sides of the connector, so I soldered to the outside one like the picture showed. Unfortunately, there's really no connection there, it's just a solder pad to hold down that side of the connector. So after resoldering the wire to the inside middle connection all seems to be well.

Ok, I've got a problem with the audio coming into the usb adapter. I've made the circuit according to the schematic not the picture. I was testing it hooked up to a windows computer and I could play a sound clip I recorded and it transmitted the audio. But when I was trying to receive audio from another radio while recording in sound recorder I got nothing. The audio is coming out of the accessory connector (RX Audio Pin 11) on a Motorola Radius M208, could it be that the audio level is too low? Jeff WQEX694 KB1SPH

No TX DTMF on iaxrpt
by Bruce Forestal 10 Jul '09

10 Jul '09

I've been working with iaxrpt on a laptop running Win2K and a Mac running Fusion/Win2k. I've got TX/RX audio and PTT working on both but I can't seem to get the DTMF to pass over the network to the Asterisk node. I can hear the DTMF tones coming out the local laptop speaker. I am using the alt-number keys to generate DTMF. Also the DTMF keypad does not generate tones although I can see the text appear below the pad so I know at least clicking the pad keys with the mouse is working. Thanks, Bruce Forestal wb6are(a)gmail.com

That would be another great use for the tones, choosing which remote node you would want to connect to. How well does the DSP cut out squelch tails? If I wanted to use the COR I supposed it would be just as easy to use a transistor to get the ground. Should I be worried about someone accidentally hitting that volume down button and sending 3.3v back to the radio? I don't know if there will be a difference, but this time I am making all of the circuits external. I'm using a little radio shack project board instead of trying to cram it all in the usb housing. I left the audio output jack on the board for monitoring/testing, but I removed the mic connector to route the wires through that hole. The usb adapter I got from dealextreme had surface mount jacks, so it was really easy to remove and solder wires to. Jeff WQEX694 KB1SPH P.S.

Ok, I didn't think to look at the bottom for notes. My next dumb question, for the COS, what is it triggered by? Looking at the diode, keep in mind I'm no expert at electronics, I would think it's triggered by ground. Ground goes on the cathode side right? But testing the connections on my adapter from dealextreme, it has volume buttons, it connects that pin to aprox 3.3v. Is this I/O pin capable of either one? Or am I just really that confused? On my radio I hace ground output for COS or aprox. +5v for CTCSS. I'd rather use the COS if the software can decode and encode the CTCSS for me. Also, does the software support multiple CTCSS tones like a community tone panel? Could I maybe configure multiple nodes (with different tones) and set them to the same usb device? It would be useful for giving groups their own tone, then if I had a problem I could disable that group. Thanks, Jeff

CM108 modification

Ok, I'm modifying a CM108 USB adapter, and though I've done it before I can't remember if whether the picture or the schematics are correct in the pdf file. In the picture, I see that for the mic input (RX Audio) has the twisted (or just soldered) end of the 68K and 470K attached to the 9 pin connector. In the schematic, the twisted end is attached to a capacitor (which isn't in the picture and directions) and then to the mic input on the USB adapter. Can anybody tell me which way is the correct way to hook this up? Thanks, Jeff
