RF instead of IR remote controls

I read somewhere on a forum that you can get an RF remote for ALL Pentax DSLR's. Surely this wouldn't be true of the K-x which is lacking an auxillary connection for a receiver or does it work via the hot shoe?

There are RF remotes to operate the flash (which unsurprisingly work via the hot shoe). I've not heard of any that control the camera, though it shouldn't be too difficult to make one that plugs into the remote socket (Instructables probably has a design).
I suppose it would be possible to design an RF receiver that had an IR output - a hot shoe mount might make sense for that.
Was the article you read written before the K-x came out (or perhaps just based on old information)?

As far as I know they all need the small jack plug socket to work.
I don't think the K-x has one.

I think you are right as they seem to be for the K10D, K20D etc
This looks great if you have one of those though as it is unaffected in outdoor light being RF:-

I think it was in DPreview forum I read it but I suspect the poster was wrong!

Yep! that one shows the small jackplug in the camera.
The receiver doesn't have to go in the hot-shoe it can
just hang from the jackplug socket, leaving the hot-shoe
free.

I see it also works with the K1-D..... they must know something
that we don't

......... and this onesays K-x and K-m which it can't as far as I can see.

I've got two of them one for the shutter and one for the flash. The lead you see on the right has a red plug on one end that goes into the receiver and a small jack plug that goes into the release. It also fits Canon. I'm quite sure that the K-x hasn't got that jack plug socket (mine's a K20-D).

I think they have just assumed that all Pentaxes are the same and have made a mistake It's a very good price though as long as postage isn't excessive.

Editostage if free so that makes it about £19 - £20 which is about what I paid for mine a year ago.
