No "big problem" at all. This is a down conversion rig, and you're
tuning across the IF frequency of the rig (9mHz), so you're hearing
exactly what I'd expect you to hear.
If you want complete general coverage, you need to use an
up-conversion rig.
This is the price you pay for good close-in strong signal handling (3rd
order IP). There's no free lunch. You pay for your good close-in strong
signal handling, by having poor image rejection, and garbage around the
I/F.

> Just purchased one. A big problem found in the rcvr section. At a hro store in the bay area I was tuning thru the shortwave freq's btwn 8-10 MHz. I found am signals from abt 8.8 to 9.1mhz. These were cb signals ie 9.024 MHz was from a signal at 27.024 MHz. And these were not local, but from the Midwest and east coast. Once you got out of the range of 8.8-9.2 MHz . This problem disappeared. Use of the ipo and attenuator functions. Would reduce, but not get rid of. Note antennas used a tribander with 40 meter add on. Another radio (mine) had same problem. Somthing in the rcvr bp filters is not right, heads up. Yeasu called awaiting a answer. 73 John. Wa9dgm
