Icom 7300 Spectrum Scope Settings Video
The Icom 7300 spectrum scope is fantastic! I have been using my Icom 7300 a lot and one the best features is the spectrum scope. The default settings are good, but I liked the way my Flex 1500 default scope looked. So, I’ve made some changes to the one on the Icom 7300. It only takes a minute or two and there’s a big difference. Check out this short video clip I made.
Try the settings in the above video and see how you like it.
Icom 7300 Spectrum Scope
The first important setting to me is the “Scope during Tx (CENTER Type). This allows the scope to continue scrolling while transmitting. I like seeing it and since I use CENTER type a lot, it works very well. I leave it on. (Default: ON)
Max Hold Off. I don’t care for the Max Hold to be on. Experiment to see what you like. (Default: 10s Hold)
The CENTER Type Display is another one I changed. I changed it to Carrier Point Center (Abs. Freq.). Abs. stands for absolute frequency. (Default: Filter Center).
Marker Position stayed at the default as does the VBW (Video Band Width).
Another change was done to the Averaging. Play around with this one. Mine is set to 3 (Default: Fill).
Important one for me is Waveform Type. Mine is set to Fill+Line (Default: Fill).
Here’s another biggie. Mine is black (0,0,0) for the Waveform Color (Current). (Default: R-172,G-191,B-191)
Since I liked my Flex 1500 software default scope I changed the line to green. So Waveform Color (Line) is R:0, G:255 and B:0. (Default: R-56, G-24, B-0).
Waveform Color (Max Hold) stays at default as does a few of the last settings.
The Waterfall Display = On and Waterfall Speed = Mid and Waterfall Size (Expand Screen) = Mid.
I changed the Waterfall Peak Color Level to Grid 3 (Default: Grid 8).
The last for the scope is Waterfall Marker Auto-hide and it stays at the default. (Default: ON.
I won’t go into the Fixed Edges, but I use Fixed Type as opposed to Center Type when searching and pouncing in a contest. I also like fixed type when I’m looking for QSO’s to listen too.
You can download a couple of pages from the manual describing the settings here.
