About the only IMD product I can come up with is this one 16.8 + (8 x 146.76) - (6 x 191.01) = 44.82 MHz
Which is the TCXO + 8th harmonic of TX - 6th harmonic of RX VCO to land close to the 1st IF pass band. I think the lack of filtration in this model of radio might be suspect as it uses varactor tuned strip lines. The probably offer minimal selectivity and they might not be optimized for ham band as they are voltage controlled and the radio might not be optimized for this frequency (it will program but moto cant guarantee the specifications). I'd try the notch coax stub as on your feedline as someone else suggested. On Thu, Mar 4, 2010 at 2:56 PM, Leroy A. M.
