Hello,
I just would like to bring the ATU-10 to your attention. David N7DDC has released a new version of his ATU-100 as a low-power consumption and 10 W QRP version of his popular autotuner.
The design is focused on low power consumption during operation. Latching relay are used make this happen.
And it has a communication port to interface with the IC-705 for the tuning.

SMD soldering of those small part sizes is definitly not everyones cup of tea but I have seen first pre-orders on the usual chinese trade platforms show up.
Btw. official discussion board can be found here:
And as the PIC µC is difficult to source at the moment Glen VK3PE has developed PCB variations that use larger package sizes with better availability. And some infos on the experiences:

I am myself just collecting infos on how to source from Austrian and German webshops.
