ICOM IC7300 : Nouvel émetteur-récepteur à FPGA

I bought the IC-7300 to check it out.. I don't really need it, just want to try one.

It's a great radio as the reviews say. It was fun but have decided I have enough other radios.
My main SDR rig a Flex 6500, in a different class so you can't really compare it to the IC-7300.

In excellent condition, like new. Lightly used in my non smoking shack. Comes with original box and
all standard accessories.. mic, manual etc.

Hi,
My 10 meter band is always very noisy with some sort of wide band modulation. Today I switched to FM, +/- 400 kHz on the span, and tuned around a bit and found I could hear a series of broadcast FM signals from the 88-108mhz band starting just above 30 MHz and continuing up to 36+ mhz. some of them readable. I don't hear it on my IC746PRO or either of my two scanners that cover that range.   I wonder if anyone else has experienced this.

There is aliasing above 32 MHz on my 7300, but I have never heard it in the 10m band.  You may well be much closer to an FM station than I.
I have a 54 MHz low pass filter that eliminates the FM signals that is rated at 300 watts so I can transmit through it.
It was sold by ICE (Industrial Communication Engineers), now out of business, but OEMed by another company.

I would drop them a line and see if they will return to production the model 425 DC to 54 MHz low pass filter. 
They also make AM broadcast and high pass filters, such as the M-402X.
