I have a pic that produces a
19 kHz (not fixed) TTL signal with the highs/1s lasting for 110us to 30us
I'm very new to wireless communications and would like some help in reccomending a good wireless transmitter resciever modules for the information above

Thanks dan
 
It rather needs to be radio as its over a distance of 50m and is not in line of sight

I found this but I'm not sure if it can transfer the signal faster enough

You might consider this rig:

And Roman Black's tests: https://www.romanblack.com/RF/cheapRFmodules.htm.
Note his range data. From the Ebay spec, up to 200M is possible, depending on supply voltage to xmitter. Also note that a "pre-burst" packet front end may be necessary to allow the rcvr's gain to settle.
Price is certainly a plus...

<EDIT> Just noticed the data rate problems. dan555, are you absolutely wedded to the 19K data rate? Can it be reduced to 1200 or 2400 baud?

Consider most 100mW wifi cant do better than 15-20m when not line of sight but >30m with direct and >100m with high gain antenna
 
Just noticed the data rate problems (Frequency and duty cycle testing). dan555, can you reduce your data rate to 1200 or 2400 baud?
