Is it so difficult to have schematics and pcb exported as PDF so that people do not need to fire up KiCAD to view the stuff?

I encounter this problem as well when looking at projects on Github on a near daily basis it seems.

It just led me to finding this:

Or even a picture of the physical device! I found some on a linked sales listing: https://chelegance.com/products/kv4p-ht-plugplay-vhf-radio1-...

Thanks! I was looking for that.

I see they use those cheapo Chinese RF modules (SA818). I've seen those also with SDR input/output, that's interesting. The underlying chip is very similar: The chip that will be used in this module is the RDA1846. This is a chip that's in most Chinese handhelds and is internally fully SDR but it decodes to analog. There's also the RDA1847 with similar pinout which offers the raw SDR stream and can thus be used for any mode, but with the added complexity of having to do the SDR decoding externally.

That means that this design could probably also be modified to do DMR. Though the SDR side might be a little bit too much to ask of an ESP32. On the other hand, it is only a very low bitrate signal.

Sounds like a great contribution you could make!

There are like six ways to export PDFs from KiCad. Project owners choose not to.
