I remain confused about protocols and methods for internet email and texting.
I understand APRS, which is can be very useful for our interests. And I conceptually understand IRLP, which interests me less.
But I remain confused about sending and receiving data to and from the internet that is routed as email or IM. Can someone educate me or point me towards a good resource? What are the pratical considerations of this technology, especially when using HF? Thanks.
