IC-7300 Spectrum Display in N1MM+ Version 1.0.6221 (2024)

Setup

* Keep the noise level low by setting the ref level low and not using
preamps.High noise will cause many false signals.High noise many
overload the cpu and cause cascading runtime errors.
* Must have CI-V USB Port set to Unlink from [Remote}
* Must have baud rate set to 115200
* Waterfall speed will be set to low and left there on exit.
* Spectrum scope will be turned on and left there on exit.
* The window can be opened from the Entry Window "Windows" menu. It is
the last item.
* You will not see the spectrum display menu item unless you have an
IC7300 configured. You will have to exit the program and restart it
to have the menu item display. There is little use in me spending
time fixing this kind of bug until I have decided that this is a
permanent feature.

Controls

* With focus set on the Entry Window, Shift+up will move the frequency
to the next signal towards the top of the bandmap (right on
spectrum). Shift+down will move the frequency to the next signal
towards the bottom of the bandmap (left on spectrum).
* Shift+up/down will *skip* signals that are within tuning tolerance
of dupes and non-workables.
* Shift+up/down will stop at the low and high frequencies in the
spectrum.If you are using center mode, the spectrum will re-center
on the low or high edge frequencies as appropriate.
* Signals are assumed to be on 0.1 kHz boundaries. Jumping will be in
0.1 kHz steps. Use the up/down keys to tune in the signal. If the
tone is too high, press the down key. Use the up key for signals too
low in tone.
* Sig (db) is level of signal as shown on the display, relative to ref
and indludes the preamp level
* Frequency is low to high whether in center of fixed mode
* Snap to sig - when checked jumps to the nearest signal when you
click on the chart. (within 2 kHz).
* Radio1/2 allows a choice of which radio to display.
* Signal count is the number of "signals" found above the noise floor.
Roughly equivalent to how many times your cursor will stop
traversing the screen. It does not take into account the number of
non-workable spots.
* Reset is a button that clears the display and starts over.Useful
when changing ref level on the radio. Also stops/starts the spectrum
stream from the radio.
* To mark signals that you don't want to work, use the Mark button
(Alt+M to mark, Alt+D to remove).

Mouse

* Left click will set radio receive frequency and snap to closest
signal if check box is checked.
* Right click will set split frequency to that frequency.Snap to
signal is ignored.

Colors

* White is the instantaneous signal level as shown in white on the radio
* Blue is a "decaying" representation of the signal *similar* to that
on the radio.
* The green line is the current Rx frequency
* The horizontal blue line is a measure of the noise floor above which
signals are found.
* The vertical red line, if shown, is the tx frequency when split.

Notes

* More testing has been done with fixed mode than centered mode. Watch
for bugs at the end of the span range with both, but especially with
centered mode
* Gaps will appear at the beginning and end of the center mode
spectrum display if you are not currently tuned to a whole kHz
frequency. This is normal.
* This is a "first draft" so expect bugs.I will work with those
testing it by publishing revised versions in the experimental gallery.
* If your radio is not on or not configured properly, you will need to
close the spectrum display or perhaps close the program and reopen
to get the display to work.
* The program does not yet remember that you had the window open, nor
does it remember your settings for various configuration items, like
Snap to Signal.

This is pretty cool!

Some initial observations on my end. I understand this feature may or may not be continued.

I'm going to go into SO1V mode for tonight's Phone Fray and also give it a workout in 2 or 3 of the CWT's tomorrow in both Fixed and Center modes and will let you know of any hiccups.

So, if you decide to keep the feature, maybe the following below will be of help.

My setup involves SO2R (Elecraft KX3 and IC-7300)

If the 7300 is set to Radio Nr 2 (R1 is KX3) the R2 entry window will not have the spectrum option displayed (despite restarting the program)

Works great if I put it in SO1V mode, setting the 7300 to Radio 1.

I also tried the following scenarios

Scenario 1

1. 7300 R1 SO1V mode

2. Set mode to SO2R. 7300 is R1, KX3 R2.

Works as expected, can see and use the spectrum display for the 7300 (R1)

Scenario 2

I think I know what the issue is, but I don't know if I will be able to fix the problem for tonight.

For those trying out the IC7300 display I will be posting fixes to the experimental code in the experimental gallery. Check there for a new version before you start testing. (Hint: there is a new version there already.)

Had some time to experiment with it further and here's some notes after using it in CWT and FLQP:

1) Occasionally i notice that the instant signal line marker when it crosses over the dot next to a callsign it will get cut off below that dot (above still works while the signal is there). Same thing happens to the RX freq marker. I attached a screenshot that shows it

2) In this scenario in FQP:

VFO A 14.030 (CW)

VFO B 14.250 (SSB)

spectrum monitor is in Centered mode. Click VFO B. Click on a spot in the spectrum monitor (a SSB signal). After that, the radio goes back to VFO-A mode (CW freq).

Some nice to haves:

-Dim previously worked callsigns (like in the Bandmap)

-Maybe use the colors as set in the bandmap?

-Have a static crash indicator that displays for a couple seconds if a static crash is detected? May also be useful for those of us who occasionally forget to adjust the RFG level.

So far, I am enjoying this! I hope it sticks around (and I get the 7610 in the main radio position, and hopefully we can have 2 of these, one for each radio -- ok... I'm getting a little too excited right now)
