I bought the two radio pack from Amazon. Tested both on a spectrum analyzer to test the harmonic attenuation. One was fine with similar results as Moleculo. The other was found to be transmitting off frequency compared to the VFO. Set for 145.555 (simplex) and was transmitting on 138.500. Sent both back to Amazon for a refund.
