Holy schtuff! Just got the CHIP
by Buddy Brannan 09 Jul '16

Hi y'all, Well...this could be fun... I just got the CHIP from http://www.getchip.com They're finally catching up all these preorders; I orderd way back after Thanksgiving when they had $1 off, so you could get the $9 CHIP for $8. Well, really, $13, because of $5 shipping. OK fine. If you thought the Pi was small, this thing is even smaller. Built-in wifi and bluetooth, 4GB onboard storage., 1 USB port, 1 micro USB (which I think can also send data, but is mostly for power), one connectory for audio out+video or audio out+mic in No SD card slot...I don't think it's big enough for one anyway. Oh, and no ethernet. Again, is it even big enough? Now...if I can get a version of DIAL rolled together for it. ...or a version of asterisk with app_rpt built on its Ubuntu derivative... Heck...the USB audio interface might just be bigger than the computer. *Hmm* And interestingly, this is slightly more than. bare circuit board, even with no case on it it actually has the board mounted in something. I really could just about see a handheld All Star node with one of these strapped to the back of a handheld. -- Buddy Brannan, KB5ELV - Erie, PA Phone: 814-860-3194 Mobile: 814-431-0962 Email: buddy(a)brannan.name

It'd be nice to throw high-end hardware at everything, but if you had a very large system to build - I don't think you would be doing that. And we do have a very large system to build... Lists aren't about one person building one machine, lists are about system-builders assembling a nation - and that process being doable with quality dividends, so it is easy for one person to announce costs being minimal for one system, but if that single device were implemented globally, that would be six or seven figures. That'd be nice for those who supplied that device, but I don't think they'll get it. I mean to say, app_rpt can, and should, be on every transmit and receive interface on every mountaintop. Be honest - conversion of all systems is our goal, not because we might, but because of the immense flexibility it would forward, without really any effort at all. So how to actually get that? Using a $300 box for every TX and RX? No, it's not going to happen. Using a <$100 box with four TX and four RX interfaces? Just maybe.. > I suggest finding a way to replace the I/O lines with something else > because ANY dsp should work fine for the audio. I think the PI itself > has them.

The Pi is already good to go, and some of the channel drivers will already use the onboard I/O. There just isn't a driver that does ALSA audio, DSP, generic GPIO, and voting. If there was, we'd never be having this discussion ever again. Also, it'd be dead trivial to write a config script to set the whole thing up. > drivers? hardware? integration with existing codebase? takes time and > (unpaid) effort. -- Bryan All the really great ideas get implemented at some stage. The person who WANTS to do it, notes it and puts it on the back burner - to be implemented NEXT. All visionaries implement the BEST idea, not their own idea. Discussions like this only pave the way, or is it 'a' way.. Or maybe, digital is better... S

I have had a few fake products delivered, but always they are extremely fast on the 'refund and apologise profusely' button. I wouldn't call it a bad experience. S

RTCM 1 PPS Specs
by Joe Moskalski 06 Jul '16

06 Jul '16

OK, I am currently trying to get my GPS unit running with my RTCM. I am using a QRP Labs QLG1 at the moment for testing which does output a 5v 1PPS. The pulse from the QLG1 is 100ms long. I haven't been able to get the RTCM to achieve a GPS lock so my question happens to be what are the parameters besides the voltage level that need to be met for the RTCM for a valid 1 PPS input to it? I haven't been able to find this information online anywhere.

Another excellent question. This I2S needs looking into. http://audioberry.com/beginners-guide-raspberry-pi-i2s-audio/ S

dingotel dongle
by Greg 05 Jul '16

05 Jul '16

Hello all Is there actually some way to use the dingotel dongle in Allstar? I see reference to it in simpleusb.conf.. I have one but don't see any driver in Linux to trigger PTT as I tested it on Echolink etc. Thanks for any help! Greg

dingotel again
by Greg 04 Jul '16

I gave it a whirl. I can get the thing looking good in simpleusb tune menu and it even PTT's without vox! However, my node it not working with it, it seems. Where and what do I check? Looks a little promising..

Don't know. CM119 chips can be bought new off alibaba.com for cents each, qty 1, and free freight, and a breakout board to mount them is equally trivial. Steve

Hackable CM108 fob
by DuaneVT . 04 Jul '16

04 Jul '16

I have several of these fobs. CM108 and open to mods. Looking at the board carefully, it looks like the mic tip and ring are wired together and removing 0-Ohm chip resistor R6 opens the 4V mic Vbias line from CM108 pin 25, leaving mic T+R pins connected to CM108 MICIN pin 27 through a chip cap. Mic T-R pads are on J3 on the red LED side of the board if the jacks are removed.I just confirmed R6 does indeed remove the 4.5V mic bias.
