Hi,
I've just put this together for you. It works on my USRP2 and WBX but if you have a USRP1 then you must change 'tx_samp_rate' to '64e6/256'.
Download the following two files from
http://scanoo.com/grc :
1) 20120122_scanoo.com_wav_nbfm_tx.grc
2) illbeback.wav
Load the GRC file and edit the WAV source block to point to 'illbeback.wav'. Set your PMR446 receiver to channel 7 (446.08125 MHz) and run the flowgraph. With any luck you should hear Arnie :)
Cheers,
Mike
