I got my general license about 10 years ago. Between work and now retirement I have not had much time for ham. In preparing for future unrest my son and I decided to work on finding a way to comm without internet or cel phones. I bought a signalink usb to hook to my ICOM 718 and my Yaesu 2900r. Using fldigi for HF we have found a variety of modes to chat with. Have not been able to connect via HF to winlink, but very successful with winlink on VHF. Also use HT's with APRSDROID on phone and APRSISCE32 on my laptop. It has been a real struggle to get it all working reliably but after a month of youtube, internet searches and experimenting it is all working now. So if you are having issues stay working on it.
