N1MM + SDR panadapter with display of marks from logo and DX cluster

A spectroscope window has been added to the N1MM + contest log. It works on the principle SDR panadapter with connection to DX cluster and a diary. It also includes several interesting technologies, for example, searching for a free spot on CQ or jump tuning after signals.

N1MM+ can acquire data for display in five ways

  • via CAT data from TCVR, which will support it (newer ICOM)
  • via the ExtIO DLL from the SDR program
  • directly load IQ data (IC-7610)
  • consume level data from another source (Flex SDR TCVR, N1MM spectral windows, Waterfall Bandmap programu
  • via the Airspy spyserver program

An example of connecting N1MM+ via Win4Yaesu Suite:

Waterfall Bandmap SDR program
Waterfall Bandmap SDR program

I have a tested connection to Waterfall Bandmap software https://groups.io/g/waterfallbandmap. I deliberately did not translate this name in the list. It's about the program, which is intended for SDRPlay, FunCubeProPlus, HackRF, LP-PAN, SDR-IQ, RTLSDR, SoftRock and similar types of SDR receivers. The program is available in this discussion group after registration.

Waterfall Bandmap can be connected to the intermediate frequency of the receiver or to the antenna. I have z FT-1000MP output intermediate frequency to a classic SDR receiver connected to the sound card. Since I did the configuration before in various SDR programs, so it's basically a normal setup. It consists in determining the driver and input of the sound card, font width. It is also possible to set the frequency offset if you use, for example, an SDR with sampling at a high frequency (not audio).

Originally, I fed the FT-1000MP to a favorite program via an SDR receiver PowerSDR, which did work correctly, but the disadvantage was the absence of a possible retuning of the TCVR from this window or the exact knowledge of the signal distance, which can be seen on the spectrum and not to mention the display of logged brands and brands from the DX cluster. Anyway, it was usable and it also brings more, and relatively high-quality receivers. It looked like this:

On the N1MM+ side, it is necessary to set up sending data via a local server (Configure Ports…, Broadcast Data), a to:

The lowest shortwave amateur radio band with a wavelength of 160m is also called topband, enter
Spots , enter

Other settings are logical, the data source is set in the spectrum window. After starting the Waterfall Bandmap program, the transfer to the N1MM+ window takes place. By setting the sensitivity and other parameters, you can adjust the window as needed, whether it is sensitivity, resolution, colors etc. I recommend following the guidelines from the site https://n1mmwp.hamdocs.com/manual-windows/spectrum-display-window/

Sample N1MM+ SDR adapter-u s with display of signs from the logo and DX cluster:

Multiple keyboard shortcuts are available for efficient use, for example SHIFT + the up arrow retunes the TCVR to the next detected signal in the SDR spectrum, SHIFT combination + the down arrow tunes in the opposite direction.

There is something else, which is not in N1MM+?
