For RF operations, you can use either a hardware modem (TNC) or a sound card (computer, built into the radio, or external such as SignaLink etc.) with one of a variety of software modems to interface between your radio and sound card.<\/p>\n
For HF with a sound card there are several options:<\/p>\n
ARDOP is included in Winlink Express.<\/p>\n
To set it up you will need to open an \u201cARDOP Winlink\u201d session, go to Settings; ARDOP TNC Setup; and enter the audio settings for the sound card you use for digital (such as \u201cUSB Audio CODEC\u201d used by my SignaLink).<\/p>\n
VARA HF: You can download the VARA HF\u00a0 software at https:\/\/rosmodem.wordpress.com\/<\/a><\/p>\n The Free version is limited in speed. The paid version ($69.00) removes the restrictions. That fee also covers usage of VARA FM.\u00a0 I\u2019ve found the free version very workable. A friend of mine, Evan, WH6ECG with Hawaii ARES has done field testing with the mainland and found VARA HF very robust with good throughput in weak band conditions.<\/p>\n Once installed, you will need to open a \u201cVARA HF Winlink\u201d session, open Settings; VARA TNC Setup, and enter the path to where you installed the sound modem in the \u201cVARA Modem Location\u201d box.<\/p>\n Winmor has been phased out. It is not supported by any RMS. If your version of Winlink Express shows Winmor as an option, you need to update your software.<\/p>\n If you have an SCS PACTOR hardware modem, there is a \u201cPactor Winlink\u201d mode to use with it.<\/p>\n Rig Interface: All of the HF modes I discussed here allow you to configure them to control your radio and automatically switch to the proper frequency when selected in the software.<\/p>\n The Winlink website, https:\/\/winlink.org\/<\/a> has links to software, documentation, tutorials including YouTube videos and operating information.<\/p>\n You should be ready to start connecting to RMS nodes on HF. We will go into more detail in later training, but for now, here are some nodes to try.<\/p>\n NS\u00d8A, Geneseo IL (VARA, ARDOP) K\u00d8SI, Columbia MO (VARA, ARDOP) KF1D, Blackstone MA, (VARA, ARDOP) N4SER, Sarasota FL (VARA, ARDOP, PACTOR) (Note: RMS information current as of 5 September 2022. Check the Winlink RMS Map page for current information<\/a>)<\/p>\n Once you have your HF station configured, feel free to send a test message to KA0AZS with the mode you\u2019re using and the RMS station your used.<\/p>\n Our next training will discuss connecting to RMS nodes to send and receive messages.<\/a><\/p>\n
