Introduction to UV-K5 HF 0.5 (Fullband receive version)
This is an introduction to UV-K5 HF full-band reception firmware 0.4HF 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.
This article only describes the features newly added in Version 0.5.
Please check the links below for full features.
How to modify your hardware
Version 0.3HF (Most feature descriptions are provided)
Version 0.41HF (Description of Band plan function and Dual RX function)
1.Shortcut key description
After several version changes, the shortcut key was confirmed.
1.1 Frequency fine tuning (Under 1Khz)
Number keys 1 and 4 can be used to change the frequency in 10Hz increments.
Although it is a BFO adjustment, the BFO is reflected in reverse, so it has the same effect as changing the frequency below 1Khz in SSB mode.
1.2 Change frequency step
When you press the STAR(*) button, the step changes.
Step is underlined at the top of the screen and below the main frequency.
(100Khz Step)
In version 0.5, steps 500Khz, 50Khz, and 5Khz were added.
(50Khz Step)
1.3 Band Plan
When you press number key 0, Band Plan is displayed. Please check the link below for Band Plan related functions.
Version 0.41HF (Description of Band plan function and Dual RX function)
1.4 Mode Change
Pressing the 'F' key changes the mode.
Short press 'F' to change to AM<->FM or LSB->USB->CW.
Press and hold 'F' to change to AMorFM <-> SSB or CW mode.
2.Direct Input Frequency
If you press any number except the above shortcut key, direct frequency input mode will be activated.
Enter the desired frequency.
When you press the Exit button, the direct frequency input mode is canceled.
3. Changed features
- Frequency step changes from large to small increments.
(1Mhz -> 500Khz -> 100Khz -> 50Khz -> 10Khz -> 5Khz -> 1Khz)
- When you select a band from the Band Plan menu, the mode appropriate for that band is automatically set.
- Unused and unnecessary menus have been removed. (Main VFO Mode, not HF Receive mode) : U.INFO, Key.LCK (If you press the F key for a long time in main vfo mode, Lock will be activated or deactivated, so it has been removed from the menu)
4.Download
Great job! I like it ;-)

DeleteCould you publish version with 240 MHz filter switch bound instead of 280 MHz?

Just brilliant, nice work. Thanks
ReplyDeleteGreat job, I'm really enjoying it. You can support 128k eeprom (M24M01 - 999 channels) and CHIRP software. Thanks. 73.
ReplyDeleteHello
ReplyDeleteThe speaker is very close to the electronic components of the board.
How the BFO stability problem was solved. The frequency changes when you move your hand closer.
+1 to chirp module and bigger eeprom support (in my case I use a 24C512, but eventually I'll upgrade). Fantastic work! 73 de IU3POA
ReplyDeleteDSB TX Mode like IJV )
ReplyDeleteBFO stability problem solution ;D

ReplyDeleteHello! Great idea with si4732. SSB lacks gain. Make register control Automatic gain control max gain
ReplyDeleteI have started to analyze the 0.5 CEC firmware and try to write a chirp plugin. It's not working yet: https://git.okoyono.de/klaute/uvk5-cec-chirp-driver

DeleteThanks Kai, that is what i missing!
DeleteAlso a 999 channel version for eeprom upgrades .... ;)
Please do not post any errors to this blog, i will not read them anyways Alfred. My chirp module is in development and does not belong to the CEC firmware. My github repository has a issue-section. If you really need to let me know that you have problems using my software - which is not ready to use yet - dot it in my repository.
ReplyDeleteHello and thank you for your work, with the uv-k5 i have learned a lot.
ReplyDeleteI wanted to ask if there is any specific documentation for troubleshooting or common issues? Not specific to this release but the fullband project
Thanks for the mod, great work! I have installed it, the chip resets, but I'm unable to tune any frequency, pressing the side buttons exit HF mode and bring me back to normal mode. Any idea what I've done wrong here?
