[arm-allstar] Issue with USB fob going offline.

[zl1sww]

Hi Doug,Thanks for the tips. I have been playing around with several things and doing several tests.One of the test was just to see if it was a power related issue was to not linked to anything for twenty four hours and see if the system I still stable. It seems stable so moved to the next test. This test was to run at low power which is 5 Watts as opposed to running 25 watts beforehand. This seemed to make the system more stable so all I can guess is that I'm getting RF into the USB fob somehow. I've added some ferrites and also rerouted the antenna cable to keep away from the Raspberry Pi box.The USB fob is made by Sanwu. They seem to be the most common with the CM108 as an smd chip.  I have ordered 5 more off Ebay just in case. Might do a small pcb in place of the sockets to make things tidier instead of vero board and smd components i am using at the moment.  The antenna would be about 3 m away from the node and is separated by a tin roof. So far things are looking quite stable and hopefully it'll stay like that way. Thanks once again for the good tips.

Simon,  There could be several causes for this but most involve hardware issuesnot software.  Here is a list of things that could cause it:- A bad FOB - even if it works sometimes it might be flaky- Bad power - This is often an issue. Make sure you Pi power supply issufficient. Try another one.- Power glitches - ground differentials can cause problems. Make surethings are bonded.- RF - This is not only from HF but also from the node radio especially ifusing a close by antenna.- Possibly corrupt code. Try setting up another SD card and using it.- A bad Pi or USB port. Try a different port, different PiWhat power are you using and what FOB are you using?*73 Doug**WA3DSP**http://www.crompton.com/hamradio <http://www.crompton.com/hamradio>*On Wed, Feb 13, 2019 at 9:12 AM "Simon - ZL1SWW via ARM-allstar" <arm-allstar at hamvoip.org> wrote:> Hi all,>> I have had an allstar node running quite well for some time like 6 months> or> so.
