About UV-K5 CEC Firmware Version 0.1X (from v0.1p)

 About UV-K5 CEC Firmware Version 0.1X (from v0.1p)



1.About Version 0.1X

This version is the stable version of UV-K5 Version 0.1P

In Version 0.1P, many things were changed, including the internal variable structure, and we received feedback for about 8 days to check if there were any problems. The original plan was to just change the name from Version 0.1P to Version 0.1X, but several features were added as follows. Please read Version 0.1P for main features


2.SSB Filter (bandwidth)

  The filter can select one of these : VFO, 3K, 2K, 1.7K, 3K+, 2K+,1.7K+  

  This filter operates only in SSB mode and is disabled in existing FM mode.  If you select a filter with +, the + mode is also applied to CW mode


  VFO : Previous firmware state. It is selected among WIDE/NARROW selected in VFO



 3K ~ 1.7K : When actually measured, it is a little wider than stated.



3K+ ~ 1.7K+ : It improves the functionality of the existing filter. Based on SINAD, there is an improvement effect of about 1dB.











3.SSTV 

3.1 Scottie 1 Mode 

Scottie1 mode was added to the existing Martin1 mode. You can select it from STVEnc in the settings menu.



3.2 TX Screen preview
Shows which screen is being transmitted.


3.3 QSO TX Number

  SSTV transmission sequence record. It is displayed at the top right when transmitting SSTV.



3.4 SSTV transmission resolution has been increased. If this causes problems, I plan to reduce the resolution again.

X-TAL is not connected to the MCU (CPU) used in UV-K5. (Internal LC res) So, there is a slight problem during precise transmission like SSTV.

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.
