At 1 mW or less on its operating frequency, this is unlikely to cause any problems. The 2nd harmonic and higher order even harmonics are over 30 dB down from that, and the odd harmonics are 7-10 dB down. It certainly shouldn't cause any issues at VHF.
That said, you can always add a simple in-line LPF to roll off the harmonics the additional amount desired. 73, Eric On 4/27/2011 3:45 PM, Bruce Beford wrote: >> With the XG3 and an attenuator it would be very easy to duplicate these >> tests.
