so ive been running my station remotely for about 8 months now using RemoteHams and honestly most of the time its fine but i keep getting these random disconnects that just kill whatever im doing mid-transmission. its not the internet on my end, ive got fiber and the ping to my home QTH is like 12ms which is basically nothing. the rig is an IC-7300 and im using the RCForb client on a windows 10 laptop at the remote end.

the weird thing is it doesnt happen on a schedule or anything predictable, sometimes i can run a pileup for an hour no problem, other times it drops every 15 minutes like clockwork. ive looked at the logs and they dont really tell me anything useful. started wondering if maybe its something with the router at the home end doing some kind of session timeout or the ISP there being flaky — that end is on cable which is probably the weak link honestly.

also running Echolink through the same machine for some local linking and i wonder if theres some kind of port conflict going on. has anyone tried juggling both on the same box and run into weirdness. or is this just a RemoteHams thing and i should look at other options for the SDR side of it

yeah the cable modem side is almost definitely your problem. ive seen this exact thing where the ISP will silently drop idle-ish UDP sessions after some timeout period that you cant control from your end. the RemoteHams protocol is pretty chatty so it shouldnt trigger that but if your cable modem is doing NAT and it decides the session is stale for whatever reason thats basically game over for the connection and it wont tell you why in any useful log.

what fixed it for me was putting a cheap little GL.iNet router between the modem and everything else and setting up a keepalive ping to something external every 30 seconds. sounds dumb but it kept the NAT table entry warm and the drops basically stopped. also worth checking if your cable modem has a DMZ mode you can put the remote PC in, sometimes that helps with the port stuff too.

on the Echolink conflict question — i ran both for a while and didnt have issues but i was very careful about which ports were forwarded where. if youre letting Windows firewall manage all that automatically i wouldnt trust it to sort it out cleanly

might be totally off base here but have you checked if the 7300s USB connection to whatever PC is at your home end is stable? i had something similar and it turned out the PC was suspending the USB port after a few minutes of what it thought was inactivity. drove me crazy for weeks before i figured it out. just a thought, probably not your issue but worth ruling out
