Re: Curious about a failure

Thanks for all the theorizing and the potential solutions. Turned out the problem was most likely a corrupted configuration and a too small SD card. I am not sure if that is what actually drove the failure, but all is in balance now. Interesting observation: I could not get the latest image (5/28) a...

Curious about a failure

Of several hotspots, I have one mmdvm_hs hat - acquired second hand. Worked fine for quite a while (year or so). Pwr was always from a UPS and the unit was usually on unless exercising lightning precautions and I shut the entire station down. Fail occurred last week - it went deaf and dumb and the O...

Re: Diving Into GMSK on Arduino

Been swamped with work and a few critical projects so just read your reply! Sooo far behind... What I am trying to do is create a "D-Star modem device" that connects to the high speed modem port of an IC-7000. The purpose is to use the AMBE encoder/GMSK modem/separate mic and speaker to en...

Using Pistar to flash DVMEGA hat on a RPi

I tried to update my single band DVMEGA hat using Pistar in SSH mode. I made the strap mod that is described in Guus' instructions with the firmware, then followed the instructions on: "http://wiki.pistar.uk/Flash_your_DV-Mega_from_Pi-Star" I have had a repeated failure at the point where ...

Re: Diving Into GMSK on Arduino

Thanks Andrew, Aware of the D-Star only bit. I am not much of a DMR user and don't have C4FM at all - my emphasis is really on non-voice digital modes and HF (including D-Star). I have been in conversation with Guus sporadically about the idea. He indicated that he had planned to work on it a while ...

Diving Into GMSK on Arduino

:shock: Just starting to play with this. Looks like it is particularly for repeater/hotspot use. Was hoping that using Guus’ GMSK and AMBE 3000 shields together on an Arduino Mega board would get me to a local combo that would do the work of the MOENcomm *board for HF and up. If anyone has tried it ...
