Nowadays, digital communication is popular in amateur radio. JT65 and FT8 are capable of DX communication with weak signals.
In the era of urbanization, the space for installing antennas is gradually diminishing. So we seem to prefer communications that can be transmitted away with weak signals.
Install wsjtx, the most representative software for weak signal digital communication, in Raspberry Pi.
The basic setting for Raspberry Pie is 'Raspberry pi 3 Setup (basic)' on this blog.

If the installation order changes, it may not work normally or you see the many erros because wsjtx uses other libraries.

I believe both of the URLs in section 9 (above) are now broken. As noted in the previous post, the key server does something but it may not be working completely.
ReplyDeleteThe URL at ki7mt is "not found"
bummer
check it before buying Raspberry Pi
