Icom 7300 Mini Scope And Spectrum Scope Explained

What exactly is the Icom 7300 Mini Scope and how does it differ from the Spectrum Scope? That M.SCOPE button on the 7300, I have used it plenty thinking it stood for “Monitor Scope”, but no, it stands for Mini Scope.

Icom 7300 Mini Scope

Here’s what the Icom 7300 full manual says about it on page 5-4.

“The Mini scope screen can be simultaneously displayed with another function displays, such as the RTTY DECODE screen and the AUDIO SCOPE screen. Push M.SCOPE to turn the Mini scope screen ON or OFF.”

Spectrum Scope

I think every Icom 7300 owner knows what the Icom 7300 Spectrum Scope is. Just push the MENU button on the front and then tap the SCOPE button on the LCD. That brings up the Spectrum Scope. Says it, right under the frequency display, “SPECTRUM SCOPE”.

The IC-7300 has two spectrum scope modes. One is the Center mode, and another one is the Fixed mode. The spectrum scope displays important information in it’s header like, span, edge, speed, RX/TX markers and the FIX/CENTER icon. You can find all of the information in the full manual starting on on page 5-2.

There is quite a difference between the two and I’ll go over it in the following clip. Also shown is each screen the mini scope will display on and how to quickly get rid of that annoying half screen.

Hi Rich –

Enjoyed the mini scope video.

That raised a question – on page 5-3 of the “short” manual Touch Screen Operation is explained. Para. 3 explains that you can touch a portion of the band and the rig will change to that freq. I can make it do this – but for the life of me I can’t see much utility in it because I never get right on the spot i want. have you found any real benefit of this function?

Thanks, Wes AI 4FH.

Hi Rich –

Another question – a friend has a rig that – for working split – allows him to hear receive audio of one of the freq’s in one ear of his stereo headphones and the audio from the other freq in the other ear –
do you think there’s any way to do this on the 7300??

Thanks, Wes.

OK-I didn’t fill out the lower, so you probably didn’t get my question-here it goes,

On occasion, the noise baseline width seems to be amplitude modulated and it’s “width” varies at about 1-2 cycles per second. It happens with external power line impulse noise, and perhaps from the modulation peaks of a strong 1500 khz AM broadcast station nearby.
Is this normal? I tried to find a technical discussion of interference effects upon an SDR digital design with direct A to D conversion-but nothing found.
Thanks,

Thanks, I just received a note back from ICOM

Thank you for contacting Icom America.

Watched a video online on the “corderoy” effect. Based on that video the operation of the scope is typical of what will be displayed in really bad band conditions with high levels of interference and atmospheric noise.

Rich,
Icom went searching for the video. I think it’s this one, although I sometimes have more extreme effects in my setup. But, good to know the manufacturer says it’s normal for the 7300. I wonder about the 7610 software etc.??
