1. I haven't looked at the specs -

Are the bands on this radio all dual conversion or are they demodulating harmonics?

2. Dual conversion I believe


Demodulating harmonics?

3. I suppose what I should have said is 'intermodulation' which would be the proper term....

Or single conversion between the LO and various received frequencies.
Some of the lessor expensive multi-band radios do not use dual conversion, they cheap out and use cheap front end filters to take advantage of mixing harmonics - it works, but at the expense of sensitivity.
