If this is one of the Andover units off of Ebay, just use a small 13.8VDC to 120VAC inverter coupled to the Travala "fat snake" PSU which came with it. This will provide the isolated ground you need. If you are running on battery power, then this setup is preferred due to the issue in the second paragraph below. You can't hook 13.8V to directly to these Andover PC's as the power supply inside of them is only designed to accept 12V +/- 5%. Steve WA6ZFT > > Mark > > >

Igologic i3386g Mini-ITX CF boot and Power supply
by Mark Hergesheimer 21 Apr '09

21 Apr '09

Is there a packaged image for the Igologic i3386g Mini-ITX booting from the CF card and using the URI that someone would be willing to share? If so where would I find it? (I'm new to the list) Steve had mentioned that the power supply for the IGoLogic i3386g Mini-ITX should have an isolated ground and I found that the once the power supply jack was unbolted from the case that the input ground was isolated from the PC grounds. Would this be enough isolation to defeat the ground loop problem? Mark

Permanent Links?
by AFA6VC 21 Apr '09

21 Apr '09

Hi Everybody, Is there a timer which causes a "permanent" link to drop? I have two repeaters linked with a "permanent" link, however I notice it keeps dropping off randomly throughout the day. Not sure if there is a timer or something I need to look at. Any advice for keeping repeaters permanently linked is appreciated. Also, any comments on setting up jitter buffer are welcome. I have the jitter buffer set up on the IAX2 link in between the repeaters. Should I also set it up in the usbradio.conf file? Thanks, Vic

Update on Allstarlink server status
by Stephen Rodgers 21 Apr '09

21 Apr '09

The server went down due to I/O errors on the disk partition. I was able to restart it with the help of the hosting service. It is back up, but the the hosting service will be running some stresstesting to determine if the disk drive needs to be replaced. The server may be up or down for the next few hours. Steve WA6ZFT

more on FT897 remote
by George Csahanin 17 Apr '09

17 Apr '09

Just did some more investigating. I can control frequency and mode now, just fine. Can't control PL on/off, PL Freq, repeater offset (I thought that worked from preset channels in rpt.conf, but it was auto repeater offset doing that) And then the PTT. I'll guess I can usbfob that PTT, like I did the UHF node radio. But when I discovered that the AM tune (*79) (case 119) put it into transmit, I figured that was the PTT mode select, over a serial port command (0x88, or was it 0x08...one's on one's off). I see PTT Off in the source, not on. So just need that clarfied. I can hook the radio up to HamradioDeluxe and it controls fine. Are there any serial port controls, parity, stop bits, word length, etc? That could impact this somehow. My rpt.conf remote stanza, bold ones work, others readback as though they worked (double beep or speech) but have no effect on the radio: 0=remote,1 ; Retrieve Memory MM (*000-*099) (Gets memory from rpt.conf) 1=remote,2 ; Set freq. VFO MMMMM*KKK*O (Mhz digits, Khz digits, Offset) 2=remote,3 ; Set tx PL tone PL Tone HHH*D* 3=remote,4 ; Set rx PL tone 40=remote,100 ; Rx PL off 41=remote,101 ; Rx PL on 42=remote,102 ; Tx PL off 43=remote,103 ; Tx PL on 44=remote,104 ; Low Power 45=remote,105 ; Medium Power 46=remote,106 ; High Power 711=remote,107 ; Bump 20 714=remote,108 ; Bump 100 717=remote,109 ; Bump 500 713=remote,110 ; Bump +20 716=remote,111 ; Bump +100 719=remote,112 ; Bump +500 721=remote,113 ; Scan slow 724=remote,114 ; Scan quick 727=remote,115 ; Scan fast 723=remote,116 ; Scan + slow 726=remote,117 ; Scan + quick 729=remote,118 ; Scan + fast 79=remote,119 ; Tune (brief AM transmission for automatic ;antenna tuner) 51=remote,5 ; Long status query 52=remote,140 ; Short status query 67=remote,210 ; Send a * 69=remote,211 ; Send a # 6=remote,6 ; Set mode The Yaesu Opcodes that don't function are all over 0x08

Problem with HF remote
by George Csahanin 16 Apr '09

16 Apr '09

OK, figured out the FM problem. The docs were'nt clear on needing to include an offset, and that it is 1, 2, or 3, but stared at the source long enough and figured that out. Last remaining problem is setting the offset, I enter a freq like 443.675 + as *1443*675*1 (or 2 or 3) and the freq sets.to FM mode, but offset does not set. PL setting, I can command pl receive, transmit oin off, but it doesn't actually set the radio, voice telemetry says that it does, however. Same for setting PL freq. Lastly, does the remote send a serial command for transmit? *79, am mode for antenna tuner keys the rig, nothing else does. What I keep finding is that most of what I'm missing is in the source, but exact commands and/or syntax is what I'm missing. I've looked over Xipar, ACID, QVRC, etc googled it and just cannot find the right stuff. So if someone can direct me to it, I'll be a happy camper. I've also modified the source for 0-30 mhz, and 30-56, 108-138 AM, 140-164 FM, 420-470, etc. Nice for monitoring. The vox action is fine on the remote rx, is there a way to adjust that? I figure some way to make use of rxnoise and rxsquelch might do it. The transmit thing is puzzling. I guess if I were a programmer it would be easier to chase it all through app_rpt.c Oh and I'm using the most recent version .999 from about 8 weeks ago GeorgeC George J Csahanin Director of Engineering and Operations LIN TV Corp.

app_rpt as a controller
by Ramesh Dhami (VA3UV) 16 Apr '09

16 Apr '09

Hi Steve and all; Now that I have caught the controller bug, and further to my previous note on the same topic, I see that the USB fob and the URI's do actually have two audio outputs (left and right). Further usbradio.conf can also be configured such that output 'A' is audio and output 'B' is the tone. This is great... my question then is whether the tone output can be enabled or disabled for things like the ID, courtesy tone, etc, and further whether the timing between the drop of PL and drop of carrier can be configured? Same would apply for the composite audio scenario as well. Thanks! Ramesh.
