Don’t know if this is any good for someone out there, seems to only tune between 88-108, has an audio input you wouldn’t normally get in these types of module, don’t know weather it produces a clean carrier or not. :tup

You would want to get it with the control board, it wouldn't be much use without the screen unless you can interface with it. 8-)

With a layout as shown, the output is unlikely to be especially clean.

Its buyers own risk, 8-) not much use if it doesn’t to tune from 87.5 -88 though, (suspect the only frequencies which are clear are below there) don’t know if that is an audio signal thats been injected into seems to have carriers either side on the spectrum, might be some close in view, as I like to see a tall thin carrier. It would still be quite hard for someone to make a tx from this, you’d have to know the rf output level of it, assumming it was clean. If you have a clean source, audio input, the rf output level was known, someone would have all they need. 8-)

Hmm, link seems to be dead.
