I received my OpenSpot 3 some days ago, since then I have struggled to get the hotspot connecting to the DMR network.

Connecting to my Wi-Fi network works fine (DSL modem router), but it is impossible to get the OS3 connecting to DMR servers like BrandMester, D-star etc. using my DSL connection (the OS3 flashes blue/yellow).

After serval factory reset, countless attempts with different configurations, I realised that the problem appears to be an NTP-server issue (see log printout below).

I tried then an alternative connection by using Internet sharing in my GSM-phone (mobile hotspot) and suddenly OS3 started to work fine.

I have checked my DSL router setup, but I cannot see anything that can be changed regarding the NTP in the router itself. So, I assume that it is my Internet provider that somehow has blocked the use of NTP on the network due to security?

My question is whether there is anything in OS3 settings that can be changed, so I will be independent of the NTP server on my DSL network?

Please note that I did try to change the IP settings, as described in the user manual at on page 71, but unfortunately without result.

I hope someone has a solution by changing in the OS3 setup (or in my DSL router), because I do not think it can be expected, that my ISP will make change in the network configuration.

Kind regards
OZ8RZ, Hans
