Awesome! Video soon on how to get this shortwave coverage?

I am using firmware created by KD8CEC. Hardware modifications are also required. Please refer to these URLs for details. www.hamskey.com/2024/02/introduction-to-uv-k5-hf-fullband.html www.jh4vaj.com/archives/42905
Хлопки АРУ при переклюяении синтезатора убивают всякое желание крутить настройку. В ATS последних версий вроде исправили это, или нет. У меня приёмникATS-20 первой версии и перестраиваться на нём то ещё удовольствие и шипит он как фм приёмник в отсутствии сигнала

The completion level is likely higher in ATS.

The existing only firmware mods will not give you the same sensitivity since the RF to IF Noise Floor is 3dB higher in the existing HF and SW bands due to no image rejection and higher thermal noise hitting the mixer of the stock UV-K5 at HF and SW frequencies! Only way to get that sensitivity back is with external filters to block the image frequencies ( FM BC and Aircraft frequency band ) folding/falling into the receiver at HF and SW bands The mixer at HF in an stock UV-K5 gets hit with a 3dB higher noise floor masking the sensitivity of the receiver The new Si4732-A10 has built-in image rejection and lower LO phase noise so a only firmware mod will not fixed image noise degradation at HF and SW Rx reception The Si4732-A10 CEC module is far superior to any firmware only mod for HF and SW Sensitivity and better receiver image and spur rejection I know, not all of you are RF Design Radio Engineers, to understand the technical aspects of this, but trust me, the Si4732-A10 module is a real breakthrough for the modified UV-K5 radio’s

What firmware is this? or what modifications did you do? It's pretty cool stuff.
