Do N1MM+ contestového logu pribudlo okno spektrokopu. Pracuje na princípe SDR panadaptéra s väzbou na DX cluster and a diary. It also includes several interesting technologies, for example, searching for a free place on CQ alebo skokové ladenie po signáloch.
N1MM+ can acquire data for display in five ways
- cez CAT dáta z TCVR-a that 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 program
- via the Airspy spyserver program
Example of connecting N1MM+ via Win4Yaesu Suite:
I have a tested connection to Waterfall Bandmap Software https://groups.io/g/waterfallbandmap. I deliberately did not translate this name in the list. This is a program designed 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, it is basically a normal setting. 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 are using, for example, an SDR with sampling at a high frequency (not audio).
Originally I am FT-1000MP fed through SDR receiver to your favorite program PowerSDR, čo síce fungovalo správne, ale nevýhodou bola absencia možného preladenia TCVR-a z tohto okna či presná znalosť odstupu signálu, ktorý na spektre vidieť a nehovoriac o zobrazení zalogovaných značiek a značiek z DX clustra. Akokoľvek, použiteľné to bolo a naviac to prináša aj ďalšie, a to pomerne kvalitné prijímače. Vyzeralo to takto:
On the N1MM+ side, it is necessary to set up sending data via a local server (Configure Ports..., Broadcast Data), namely:
Radio, enter 127.0.0.1:13063
Spots , enter 127.0.0.1:13063
Ostatné nastavenia sú logické, v okne spektra sa nastavuje zdroj dát. Po spustení Waterfall Bandmap programu tak dochádza k prenosu do okna N1MM+. Nastavením citlivosti a ďalších parametrov si okno upravíte podľa potreby, či už ide o citlivosť, rozlíšenie, farby atď. Odporúčam riadiť sa usmerneniami zo stránky https://n1mmwp.hamdocs.com/manual-windows/spectrum-display-window/
Sample N1MM+ SDR panadaptér-u s so zobrazením značiek z logu a DX clustra:
Several keyboard shortcuts are available for efficient use, for example, SHIFT + up arrow retunes the TCVR to the next detected signal in the SDR spectrum, the SHIFT + down arrow combination tunes in the opposite direction.
Is there anything else that is not in N1MM+?
