Notes:

  1. VHF RMS gateways can be used as digipeaters for peer-to-peer connections between local stations when Internet access to the Winlink Central Message Server is unavailable.
  2. An asterisk (*) indicates these Winlink Nodes have RMS Relay installed. This means if the internet is down messages can still be left for a recipient to pick up directly.
  3. When seeking a HF RMS gateway, a simple strategy is to listen to SSB stations on your target band to see where propagation is good. Then select a gateway from the Channel Selector in the same general part of the county. For example, if you are hearing stations in the midwest on voice, choose a gateway station in the midwest.
  4. If using Winmor, you have two choices for bandwidth — 500 or 1600 Hz. The wider bandwidth mode achieves greater throughput, but if the band is crowded, you will be more successful (and considerate of others) when you choose 500 Hz. You choose your bandwidth in the Winmor settings window after opening a Winmor session. Be sure to select a gateway having a compatible bandwidth. Better yet, use Ardop. It’s free, and it’s faster than Winmor. The VARA HF modem works even better than ARDOP, but a license to use this modem casts $69. If you are serious about EMCOMM communications, it is well worth the money.
