12:19 AM aandrew: WormFood: I think I'm going to buy a tk-790, it's 45W, 2m and 9600-baud TNC capable
12:29 AM aandrew: that'll get him void and I can put an aprs transmitter arduino type thing on the tnc
12:29 AM aandrew: radio will be about $100 as well
12:29 AM WormFood: I'm not sure how useful a TNC would be
12:29 AM aandrew: aprs seems considerably more useful than dstar at least ofr this
12:29 AM WormFood: Yeah, APRS is nice
12:29 AM WormFood: dstar also has the same feature.
12:29 AM WormFood: My dstar radio has GPS on it.
12:29 AM aandrew: it does, yes, but is proprietary and mostly icom only which might be an issue out there
12:29 AM WormFood: No it's not. It's standard protocols for GPS with dstar. Works with any gps stream
12:29 AM WormFood: I've seen it in action before.
12:29 AM aandrew: dstar itself is proprietary
12:29 AM WormFood: no it's not
12:29 AM aandrew: that isn't what I'm reading
12:29 AM WormFood: You're thinking of the codec
12:29 AM aandrew: yes
12:29 AM WormFood: codec != dstar
12:29 AM aandrew: I thought you had to use the codec in order to have other dstar receivers "hear" you
12:29 AM WormFood: AND, the patent on the codec has expired, and there are free versions of it.
12:37 AM WormFood: There is another nifty feature you can do with dstar. They make these little "access points" for them. They're tiny little transmitters and receivers, and I think most operate on 70cm. But you use your radio to talk with this AP, and it will route your signals over the Internet, and out of a particular repeater.
12:38 AM WormFood: Now those "AP"s have 2 different styles. One with, and one without the codec chip. If it has the chip, then you can access dstar using a normal radio. If it does n't have that chip, then your radio's audio is just passed straight through (and it's already digital)
01:08 AM aandrew: Yeah I was reading a bit about it, the repeaters are only useful if you’ve got dstar-capable repeaters in the area, no? aprs will repeat one hop if I understand it right, so if I can see a repeater, my message will be rebroadcast by it once. If I’m in range of 5, all five will repeat the message once
01:41 AM rue_mohr: I got it
01:42 AM rue_mohr: if I put the threshold at 30.38us I can break the stream into 2 bit packets to the 595
02:45 AM rue_mohr: polprog, well?
01:39 PM aandrew: rue_mohr: oh? you got openocd svf playback into a format that the 595 can accept?
01:50 PM polprog: sup rue_mohr ?
05:43 PM rue_shop3: I'v been defeated by a 2 speed 3 phase motor for the second time
05:43 PM rue_shop3: aandrew, I gave up, both jtag and openocd are useless, I'v worked out how to 'directly' attach a 595 to a serial port (6 passives)
06:45 PM aandrew: ah, that sucks
07:10 PM rue_shop4: I didn't want to need special software, but this isn't too bad really
07:11 PM rue_shop4: getting it to work right, is being an issue
08:45 PM rue_mohr: no I completely gave up on jtag and useless openocd
08:45 PM rue_mohr: I'm using real normal serial with RC timing to a 1 wire 595 circuit
08:45 PM rue_mohr: screw jtag
08:45 PM rue_mohr: its kinda working, the timing is a bit off
10:02 PM rue_shop3: ................................................
