So ive been trying to get Winlink going for maybe three weeks now and i think i finally understand about 60% of it. Running Winlink Express on the laptop, got a Signalink USB hooked to my 897D, and im using Vara HF which seems to work okay on the soundcard side at least.

My main confusion is around the RMS gateways. Like when i connect to one, am i connecting directly to that station's node and then it forwards my message out through the internet to the Winlink CMS, or is the actual email routing happening differently than i think? I had a message sit in my outbox for like two days before it finally went through and i couldnt figure out if that was a propagation thing, a gateway thing, or something i configured wrong in the client.

Also not sure about the peer to peer mode vs going through the CMS. For emcomm purposes whats the actual advantage of p2p if youre just sending to someone who also has Winlink Express — do both people have to be online at the same time for that or does it store and forward somewhere. Cant find a straight answer on this in the documentation, or maybe i read it and didnt understand it.

yeah the gateway thing tripped me up too when i first started. So the RMS gateway is basically just a relay — it receives your message over RF, then it has an internet connection on the backend and pushes it up to the Winlink CMS servers. The CMS is kind of the hub of everything, it holds messages until the recipient connects and picks them up. So no, you dont need to be connected at the same time as the other person, the CMS holds it. That two day delay was almost certainly just you not hitting a gateway that was actually on the air and working — some of the listed gateways in the channel selector are just not active or the sysop has it turned off. Try sorting by distance and activity and pick ones that have had recent connections.

The peer to peer thing is specifically for when you have NO infrastructure, like a real go-bag situation where theres no internet anywhere. Both stations do need to be available close enough in time for the handshake to happen, but it stores on the receiving end once connected. Honestly for just getting started i wouldnt worry about p2p yet, get your CMS flow working solid first.

One thing that helped me a lot was running the Winlink channel selector and actually looking at what frequencies the nearby RMS gateways are posting activity on recently. Theres a timestamp in there and some of those gateways that show up havent had a connection in weeks, so vara will just sit there spinning trying to connect and youre wasting time.

Also make sure your Vara HF is calibrated — if your levels are off it'll connect sometimes and not others and you'll think its a gateway problem when its actually just your audio chain. I had the Signalink drive set too hot and was getting a lot of failed sessions before i figured that out. The waterfall in Vara will show you if youre clipping.
