The VirtualWire library has apparently been superseded by the Radiohead libraries.
Does anyone know from where to download the latest version of the Radiohead libraries?
I found this Github link, but it is out-dated.
From the library main page and the RH_ASK.h page, I only see html links.
I can open the library, but there appears to be no way to download.
Am I missing something?
Yes, missing something :
This is the page for RadioHead : RadioHead: RadioHead Packet Radio library for embedded microprocessors
Start reading the text on that page and when you get to the third sentence, you can read: "The version of the package that this documentation refers to can be downloaded from http://www.airspayce.com/mikem/arduino/RadioHead/RadioHead-1.40.zip" :o
The zip file of that library is actually located on the airspayce.com website, and the only download link is in that text (as far as I know).
Reading this post did cost you more time than reading that page 
(sorry for beeing cheesy).
Ouch - that is embarrassing.
I must be going blind - or just losing focus...
I read that page sooooo many times - I guess that is the consequence of working very long hours.
Thanks for the response and pointing it out Peter.
