868MHz Transmitter

I'm looking for a basic 868MHz transmitter to send a signal to my thermostat base station.

On previous projects I have used a basic 433MHz transmitter like this to activate remote control plug sockets.

These were easy to setup as the communication is all one-way, just a case of reading the radio signal and using Audacity to measure the duration of the High/Lows and then using this to define a sequence of High/Lows on the Arduino output pin.

I want to send either an ON or OFF signal to my 868MHz thermostat base station. This communication is one-way, the signals that I have recorded when activating the Room Thermostat are the same whether or not the base station is powered up.

The 868MHz devices that I have seen (on this and other website, and eBay etc.) such as the nRF905 seem to be much more sophisticated and use Serial Peripheral Interface.

Can anyone recommend a basic 868MHz transmitter?

Thanks!

First page resulting from Google search for "868 MHz ask transmitter module" produced these.

jremington, thanks for that. I hadn't included the ASK term in my searches that only turned up the more advanced transceivers. That looks ideal, I'll re-post once I have it running.

Apologies for the delay in replying, for some reason I haven't been getting notification emails.
