[Elecraft] K4 remote protocol

[K5WA]

This may be a Wayne/Eric question but if anyone else knows for sure, please chime in.

 

I’m setting up a new remote system and want to plan properly for the pair of K4s I’ve got ordered.  Is the ethernet communication between a K4 and its Elecraft remote software TCP or HTTP? I’m assuming TCP but thought I’d better check.

 

I’m having to go through an ATT Mobile system (CGNAT) with NGROK tunnels and I’m up against a limit on reserved TCP tunnels so want to make sure I’m going the right direction before I spring for more reserved TCP tunnels.  😉  The station is WAY out in the country and that is why I’m stuck with a mobile cellular ISP.

 

Thanks,
