For anyone struggling with this, here are my findings across a few planes. Its an interesting thing I promise
First up:
There are controls you can bind that work even for those ADF units that wont show or let you set decimals:

That'll let you tun +/- 0.1 per button press, so you can make any of the ADF equipped planes work if you need to.
And here's the verdict for various GA aircraft for those of us in the UK and elsewhere with .5 congested frequencies
Tested by sitting on the ground at EGHI and trying to get 391.5 for the EAS NDB less than a mile away
Cessna 172 G1000 (or I assume anything G1000)
[image: 1d104a78-7cbb-41ee-b7be-89f68bbc2121.png]
Lets you tune whatever decimal you like. Nice.
Cessna 172 Steam
[image: e2fbdcb6-84f3-4582-8c39-76f52decf1af.png]
Fail. No Decimal tuning and no auto tuning. (you can use keybindings as above but you wont see the decimal changing - but you WILL see the freq round up to 392 when you set 391.5
Here's my stream Deck output showing (A:ADF ACTIVE FREQUENCY:1, Number) at the very same moment

Cessna 152

Fail, same as the Steam 172. No decimals but you can use the keys if you can count to 5.
Though interestingly, if you do use the keys it will show you have decimal, just not what that decimal is.

And I can tell you that 391.5 works, but .4 or .6 does not. At all. The needle just dies immediately.
JF Tomahawk and JF Pipers
Auto, baby!
Here's the unit... no room for decimals
[image: 6103ea93-7023-4175-86d6-da1f8ccda33e.png]
But about 5 seconds after tuning 391.0... We see (A:ADF ACTIVE FREQUENCY:1, Number) jump to 391.5 and lock, and the needle will move:

Black Square Bonanza and Caravan:
[image: 2cc3acf7-92b9-4f5a-99c3-4519734bb003.png]
Both let you click the Off/Vol knob to add .5 each time. And have the . feedback to let you know its on .5.
Nice.

AND

Lets you set the decimal, and lets you do that in 2 different ways, because of COURSE it does. Because it's the best plane the company ever built.
Blackbird Cessna 310R, Bagolu's Cessna Bushkit, etc etc
I guess they use the default Asobo ADF KR80TSO unit because it does nothing clever. Here it is set to 391.5 using the keys:
[image: 86b5ac4e-3a93-49cd-bb12-d6501e5ffa58.png]
"Not ideal."
Key points:
Not too many people care about ADF especially .5 tuning. But we love those who do, @Black-Square and @just-flight!
Asobo should implement auto .5 tuning, maybe in both directions, in their KR80TSO
You can make it work in any ADF equipped plane using keybinds but they're not great.
I apparently have nothing better to do than clog runways while playing with ADF
