so ive been trying to get Winlink Express set up for a few weeks now and im mostly there but the RMS gateway stuff is still confusing me a bit. I've got a Signalink USB running into my IC-7300 and i can see the waterfall activity on Vara HF but when i try to connect to a nearby gateway it either times out or i get a partial handshake and then nothing. The gateway shows up in the RMS list as active so i dont think its down.

what i'm not sure about is whether im handling the message store-and-forward side correctly. like once a message goes out to the gateway, does it just sit in the Winlink cloud until the recipient picks it up? I've been testing by sending to my own gmail and it seems to hit eventually but sometimes takes a while. Also is there a way to see if your message actually made it to the gateway or do you just have to wait and hope? I've been digging through the logs in Winlink Express but half of it is inscrutable to me. Any of you running Vara HF setups have suggestions for getting more reliable connects?

yeah the store and forward is basically exactly what you described - gateway receives it, pushes it up to the CMS (central mail server) and it sits there until the recipient grabs it. for internet-addressed stuff like gmail it usually goes out pretty fast, under an hour in my experience, sometimes way faster. the delay you're seeing might just be normal.

for the connection issues though, the first thing id check is your VARA modem settings and make sure your audio levels are sane. too hot and you'll get all kinds of garbage on the handshake. also check what mode you have VARA set to - i'd start with VARA HF rather than VARA HF Robust, the robust mode is slower and some gateways seem to respond better when you're not already fighting a weak signal. and in the session log in Winlink Express there should be a line that says something like 'connected to [gateway callsign]' if the handshake actually completed, so you can at least narrow it down to whether its getting that far or dying before that point.

one thing that tripped me up early on was propogation to the nearest gateway isn't always the best choice even if its geographically close. I'm in the midwest and sometimes I connect more reliably to a gateway three states away on 40m than I do to one 80 miles from me. The RMS list in Winlink Express shows the last heard time and you can sort by that, I usually just pick a few that have been active recently and try them rather than fixating on distance.
