Install WSJT-X and fldigi on Raspberry pi

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.

0.Turn on Raspberry PI

1.apt-get update
  Click Terminal Icon on taskbar
  type 'sudo apt-get update' [enter]

    I'm doing a new install of WSJT and am having problems with step 9 above.

  7. 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.
    The URL at ki7mt is "not found"

Release CEC Firmware v1.200 for uBITX All version(include V2, V3, V4, V5)

Release CEC Firmware v1.200 for uBITX All Version (include v2, v3, v4, v5) I did the firmware work for v5 when uBITX V5 was released, but I release it now. I received the feedback from a thankful beta tester and tested it myself by converting my uBITX v3 to v5 but I was not sure. I ordered the uBITX V5 and delivered the correct uBITX V5, so I made a little more fine-tuning. If you use V2, V3, V4, you do not need to update this firmware.

Introducing UV-K5 Version 0.1P (CW)

  Introducing UV-K5 Version 0.1P (CW Mode) CW-related functions have been added to version 0.1P. The spectrum function has been removed but is maintained in the source code. Later, when the source code is distributed, you can activate it and use it if necessary. This version is for testing purposes only. It will be redistributed as the stable version 0.2 in approximately 1-2 weeks. If you don't want to beta test, you can wait a week or two and download 0.2

Introduction to UV-K5 HF Fullband receive version 0.3

Introduction to UV-K5 HF Fullband receive Version 0.3 This is an introduction to UV-K5 HF full-band reception firmware 0.3HF using SI4732-A10. This version is released separately from the existing UV-K5 CEC firmware version. because space is needed to store a large PATCH file to use SI4732-A10's SSB. 0.3HF added several functions to use SSB for shortwave radio and amateur radio.
