Hi Oliver
Yes you are right. The Jaycar one has twice as many detents as pulses, 2 detents per cycle, very confusing.
If you take the trouble as I suggested earlier and browsed Element 14 you would have found lots of varieties and configurations. Almost if not all fully documented. Even have absolute position types.
The one I settled on was the Bournes PEC11R-4120F-S0018, Element 14 stock code 2663521, 18PPR and 18 detents and yes it is grey code. The pic I posted earlier is one of those. Even this one comes in short and long shaft flat or splined for the princely sum of $3. If you only want 1 the postage is a bit prohibitive but I purchased 10 with a price break of $2.64 so the postage spread over this quantity makes the price very competitive indeed.
As for the marketing ploy of an RGB LED inside I can never see the use. To be visible the light would have to pipe up a plastic shaft and as I usually fit a knob would be pretty useless. Having said that there must be a use or they would not be stocked.
Cheers Bob

Thanks Robert
If you are a conspiracy theorist you might wonder if the Chinese suppliers are being “careless”
I think Core Electronics should investigate this
In general I find them a great resource with a quick response to queries and good prices/service
I thought this would be relatively straightforward as part of a design for a radio transceiver for Amateur use
Am using an SI5351 modules as the VFO and an Arduino to control it all
But there are a multitude of rotary encoders out there - not straightforward…
I have used Element14 for a lot of my chips etc - expensive postage as you say - targeted to commercial designers
Will look into your suggestion sounds like a good one
