So ive been trying to get Winlink Express working for about three weeks now and im at the point where i just want to throw the laptop out the window. Running it through Vara HF on a IC-7300 and everything looks like it should work but every time i try to connect to a gateway it either times out or just sits there saying connecting forever.

My setup is pretty straightforward i think — antenna is a end-fed halfwave up about 25 feet, which i know isnt ideal but its what i've got room for. Running Vara FM too on a separate 2m rig for local stuff and that actually works fine. connects to the local RMS node no problem. Its the HF side thats killing me.

I went into the RMS list and sorted by distance, picked a few that should be within reasonable range on 40m, and tried connecting. The waterfall looks like im getting something but Vara just never completes the handshake. Is this a propagation issue or am i missing something in the software config? also not totally sure if i need to register the call with Winlink before the RMS will actually accept my connection or if that happens automatically the first time.

the registration thing is automatic, first successful connection registers you so thats not the issue. the timeout problem though — check your Vara config, specifically the bandwidth setting. a lot of people run into this because theyre trying to connect in 2300hz wide mode but the gateway only supports 500hz or vice versa. try dropping down to 500hz and see if you get further along in the handshake. also what frequency are you actually connecting on, like is it pulling the channel from the RMS list or are you manually entering it? sometimes the RMS list has stale data and the gateway moved or went offline.

also 25 feet for an EFHW on 40m isnt great but it shouldnt be killing you completely. more likely a software or timing issue than rf.

yeah what he said about the bandwidth. also one thing that got me when i first set this up — make sure your system clock is accurate, like within a second or two. Vara is pretty sensitive to that and if your PC clock is drifting winlink connections will just fail silently. run windows time sync or grab something like Dimension 4 to keep it disciplined. sounds dumb but that was my problem for like two weeks before someone on the winlink reflector mentioned it.
