Hi Philip,
I own an Icom 756 Pro and have the same problem with a nearby AM
station. This was mostly resolved wit an ICE BCB filter purchased
through www. arraysolutions.com. However when my ham neighbor goes on
the air, I can't use the radio.
I believe this is a major fault on an otherwise good radio. I am
surprised that such an expensive radio suffers from this serious
limitation. This is Icom 756 Pro's Achiles Heel, a serious one to
boot, and heck, why did I have to buy a BCB filter to make this radio
usable?
Sorry Icom, my USA made tube radios 45 years ago may have not have IF
DSP and a nice colorful display but they didn't suffer from this very
serious limitation. Am sorry to have gotten rid of them.
Have read that the Ten-Tec Orion may be better in this regard.
The ICE broadcast filter may help but it doesen't help with my neighbor.
If anyone on this reflector can offer any suggestions, they shall be
appreciated.
73 to all, Pepe
