The W0ZQ/B is back on the air for now, call it beta testing.    There have been some significant design changes.  The 222 signal is now derived directly from an RFZero board (https://rfzero.net/)  providing about 12 dBm of RF.  The RFZero board is GPS locked plus the beacon now cycles through a CW ID, then a Q65 30A sequence, then about 19 seconds of carrier, rinse and repeat.  The carrier frequency is 222.057, adjust your radio accordingly.  Right now it generates about 15 watts into 80' of LMR400 and the same big wheel at about 60'.   The power amp that I am using could running higher power but its limited right now by the drive level coming out of my intermediate amp that I am using to get the RFZero output of 12 dBm up to a little more than a watt.  I could use two or three watts to drive the final amp, so the hunt for a 222 intermediate amp continues; ideally 12 mW in for three watts out.  For now 15 watts will have to do.   I checked the spectrum output with my tinySA and any harmonics are well over 50 dB down thanks to the use of several low pass and band pass filters.   

Please let me now of any signal reports as its sort of loud here.  Especially interested in how the Q65 30A decodes.
