ok so ive been messing with Winlink for about three weeks now and i think i finally understand maybe 60% of it. got Winlink Express installed, have a Signalink USB connected to my IC-7300, and i can see the waterfall moving when i key up so thats something at least.

what im not really clear on is the gateway side of things. like when i connect to an RMS gateway am i just using someone elses station that happens to be running all the time? or is there actual infrastructure behind it that Winlink as an organization maintains. i tried to read the docs but they kind of assume you already know what youre looking at.

also the channel selection thing — i opened the RMS list and sorted by distance and theres like 8 gateways within 100 miles of me but half of them i cant seem to make a connection to. is that normal or is something wrong with my setup. running VARA HF on 40m mostly, tried a couple on 20m too. the sessions just timeout without completing the handshake most of the time.

not sure if its an antenna issue on my end, propagation, or if those gateways are just not actually online even though they show in the list. any help appreciated, this has been bugging me for a while

yeah the gateway thing tripped me up too when i first started. basically those RMS gateways are just other hams running the RMS Relay software on their end — Winlink the organization provides the CMS servers on the internet side but the RF access points are all volunteer operated. so if a gateway shows in the list but doesnt respond it could easily just be offline or the op is having issues with their setup. the list doesnt always reflect real time status super accurately.

for your connection problems on VARA HF — what mode are you using, VARA or Winmor? VARA is way better in my experience but you need to make sure your audio levels are dialed in or you'll just get garbage. the IC-7300 has that built in USB audio which is nice but you still need to tweak the input level in VARA's settings so youre not overdriving it. too hot and the modulation goes to hell and nobody can decode you. id check the VARA FM vs HF thing too make sure youre running the right one for HF.

also some of those gateways are VHF/UHF packet only and wont respond to HF modes obviously. double check the mode column in the RMS list before assuming something is broken.

the timeout issue on 40m could just be band conditions honestly. i run a gateway out of my shack and some days ill go hours without a successful connection from anyone and then the band opens up and i get 6 sessions in a row. propagation to a specific gateway matters a lot more than people think because youre basically doing a two way data transfer not just broadcasting.

one thing that helped me figure out whats actually happening — turn on the session logging in Winlink Express and watch what it spits out during a failed connect. usually you can tell if its dying during the frequency negotiation or later in the handshake. that at least narrows it down to your side vs the gateway side.
