Here are your raw packets that are making it up to aprs.fi for the last two days.

And what has made it to Outnet in the last 8-12 hours. Sorry only have that far back, I was reflashing the CHIP.

good onya Cecil :slight_smile:
Thanks for that, I forgot I could look at aprs.fi raw packets …
So the PSMMail igate in Austria has been seeing the daytime packets… It has not responded to “pings” from me though… so it must be luck!

I am not seeing any APRS messages on Americas 98 deg W in my Skylark Files Manager folder. Am I missing something?

And nothing appears in the APRS Viewer:

Is it possible that I was off the air at the time when the messages were sent on 15 January 2017 or prior? Ken

I had to reflash mine at about noon today (1200GMT), and I have this already ( from Alphasat )

My RPI-Setup also was weird and since Dec, 22 there were no new messages. Flashed a new image to the RPI this afternoon, and now it works fine.
I don´t have the APRS hardware, but it was possible to licensed ham-operators to send a message via findu.com. I proceeded according to Neils FAQ (Thank you, Neil): Recipient: APOUT and the word OUTNET in the body of the text. And voilà: 5 min. later my message arrived in my receiver.

I’ll reflash my CHIP later and see what happens. Strange thou since the CHIP with the problem just arrived from Chicago this past Saturday. Ken

Ken,
I had to reflash because I made the mistake of telling it to reboot via the network page and it killed the wifi … dead!! :frowning:
The APRS messages were arriving with no issues before that (but I did have a weak signal!)

I just re flashed my new CHIP, and am waiting for new downloads.My Amateur Directory on my USB stick had no messages in it at this time to laod. Will report back soon. Ken

In reflashed my new CHIP (delivered on Saturday) to get the APRS working, and now it shuts down after about an hour. Any thoughts here @Syed @Abhishek @zoltan ? Should I reflash again?

Ken

Yes, can you reflash? But before that, can you download the logs and post them here?

@Syed, I have re flashed with the current version on line, so I can’t get you what you want. If the problem comes back, I’ll reboot and copy out those files for you when I come back up. Ken.

Ken, what was your power input port on CHIP, and how much current rated the source?

Thanks

Say again - - I have a kilowatt monitoring device measuring the ac power going into my USB charger (wall wart). It measures a high of 11 watts to a low of 5 watts. My USB charger is rated at 2.1 amps at 5 vdc. I have never gotten such high ac readings before, so maybe that is unusual.

Which pin to ground on the CHIP do you want voltages from? Ken

hmm if problem comes back please try powering from chg-in pin(+) and gnd(-) of gpio header, 5V is fine. I’ve used jumper pins + hot glue to improves a connector once.

What? Connect where to where? Ken

“Instead of powering CHIP using the microUSB port, try using the header pins CHG-IN (U13-2) and GND (U13-1).”

Zoltan, I been double checking my USB power cords to address a question asked in my post USB Power Cords for CHIP Computers and have found with USB cords that will boot up the CHIP, and with USB cords that WILL NOT boot up the CHIP, voltages from CHG-IN to GND all read 2.489 vdc.

I have tested 7 USB power cords so far - - 2 10 footers which give a 2.49 voltage reading and flash a single light on the CHIP but won’t boot the CHIP; 3 10 footers and 2 4 footers that flash on, stay on, give a 2.49 voltage reading, and boot the CHIP.

There has got to be something else going on here Ken

PS The more I think about USB cords and chargers the more I feel Outernet shoild supply vetted cords and chargers with future Lantern sales. If one uses a DIY kit, you should power it from a battery pack - - not a USB wall wart. Ken

Hi Ken,

I might wasn’t precise: I would advise not to use micro USB, but powering your CHIP from the CHG-IN port only. Working with micro USB’s cables for power delivery is a pain… They have so tiny pins that the series resistance there can be really big thus causing high voltage drop. I know, for this one might have to fabricate a cable (like shown on my pics). On the other side CHG-IN flowing through a regulator causing some loss (extra heat) but at least stable.

An other test to do is to start ONLY your CHIP from micro USB and really quickly, about 1 sec later plug in the SDR dongle with the LNA. This works because the the power management IC “sees less load” on startup so it’s transient also smaller. Due to the quick plug-in process Skylark also recognize your dongle, so win-win.
