The new FT991A bottom view with the [SCP Unit] for dynamic real-time

The FT-991A (Yaesu latest version) bottom view with the [SCP Unit] for Dynamic Real Time Band Scope function – Yaesu is supposed to offer a  hardware upgrade program for FT-991 to add “A” features to include the new Dynamic Real-Time Spectrum Scope and Multi-Colour Waterfall Display (upgrade firmware)!

Looking an feedback on whether the FT-991A is really worth the extra +$600 (USA) cost over the old FT-991 (discounted model)

Yaesu Musen Co LTD (!rumors: FT-991 Hardware Upgrade Program) si suppone che possa offrire un programma di aggiornamento hardware anche per FT-991 per aggiungere le funzionalità “A” per includere il nuovo spettro-scope dinamico in tempo reale e la cascata multi-colore sul Display, già inclusa nell’aggiornamento firmware (Nota: !trtttasi di voci non ufficialmente confermate)
Sarà interessante creare un feedback sul fatto che l’FT-991A valga davvero la pena i circa +$600 (in USA) per il costo aggiuntivo rispetto al vecchio FT-991 (modello in esaurimento).

AM Transmission Audio Trouble in Some FT-991 Transceiver (see the latest threads on Yahoo-groups) – The cause of bad AM audio
turned out to be a incorrect level setting in the “service menu” [Note]! (*) pay attention to product warranty …, if you change a wrong setting in the service menu (by accident!), press the On/Off button to turn Off the radio, ….take care)

I do not know if someone had already mentioned but maybe i found how to solve (*)your problem : go to the AmateurTele com© link where it is explained step by step how to do – (I hope this help*)

DV4mini Hotspot: a link with a simplex frequency (UHF) and a repeater through the Internet.

DV4mini Hotspot for the 70 cm band and can use it with a D-STAR or DMR or C4FM * transceivers – The DV4mini is a very small but also very capable USB Stick that can expand any PC into a Hotspot for the D-STAR and DMR modes (C4FM * Fusion is in development) – (trial beta ver. 18.8 or later uncheck “C4FM Gateway” only DN & VW mode) – Please read official data and the User manual! (link below)

DV4mini-PC-01

DV4mini  allows linking with DCS, XRF and REF refectors for D-STAR as well s DMR refectors (trial beta ver. 18.8 or later unckeck C4FM Gateway!). With the DV4mini it has become possible to create a hotspot with minimal resources and thus get access to the (Digital Voice) DV network.
[NoteRefector is a server connected to the Internet or Ham Net and is linked to a number of digital Ham Radio repeaters. If one of these repeaters is active it will send the voice data stream to the refector- (Xrefectors are the second generation of D-STAR reflectors… etc) – (DCS (Digital Call Server) is the most modern D-STAR refector system and in worldwide use, each as 26 rooms) – (DMR refectors consist of several regional servers, ach other via a superordinate network one Hytera & one Motorola) (System Fusion supports WIRES-X internet linking – .. node station requires external optional HRI-200 !)

The DV4mini is a great UHF digital hotspot. It’s support D-Star, DMR and C4FM* !! Very promising technology in process.

DV4mini-software-01

The DV4mini will be connected thru the USB interface with a PC or a single board computer (es: Raspberry PI 2 Mod. B also a keyboard, mouse and HDMI display) and the required software will be installed: V.1.4 DV4mini Controll Panel.

DV4mini-01

Frequency 420-450MHz – Modulation types: D-Star GMSK (Gaussian 2FSK) – DMR PLUS 4FSK Raised Cosine – C4FM Fusion DN & VW 4FSK, in process* – Power output: 0.03 mW to 10 mW. – RX -120dBm – Read more to the official web-page.

Link to: Download the DV4mini User Manual ver. ENG .Pdf 

I believe not now, it’s available for Windows, Linux and Raspian ! (Raspberry Pi 2) – For those interested in digital communications, like D-Star, DMR and C4FM there’s a new dongle who will be coming out soon (… they are saying it will be available for international shipping next week).

FT-991 – MAIN V02.02 – DSP V01.04 – TFT V02.01 JUL.24 – VA7OJ’ RX & TX All Tests

FT-991  HF, 50, 144, 430 MHz All Mode – Yaesu USA Update the Firmware MAIN Ver. 02.02  – DSP Ver. 01.04 and TFT Ver. 02.01 of 24/07/2015 – VA7OJ’ FT-991 Complete Tests Report – See …news and link below –

FT-991-Adam-02

The complete FT-991 test report is now available on the website by VA7OJ’ Adam – (Receiver Tests & Trasmitter Tests) rx: MDS – RMRD – DR3 – DR2 – FM IMD rejection – NPR – Image & 1st IF rejection – AGC impulse response – DNR SINAD // tx: Power Output -CW keing envelope and sidebands – ALC compression test – Trasmitted 2 tone IMD – Tramitted Composite noise HF 50 144 & 430 MHz (22 pag.)  (Grazie, Adam per questo eccellente Test report!)

Link to: Download the Complete Tests rx-tx  of 25/7/2015

Receiver performance evaluation using notched noise, tune DUT (FT-991) such that the IF passband is centred in the notch. Calculate NPR using Equation: NPR = Ptot – BWR – MDS. – All the NPR measurements, by VA7OJ, Adam are performed in SSB mode, at 2.4 kHz bandwidth. The bottom of the notch in the noise generator (a Wandel & Goltermann RS-50 White Noise Generator ) bandstop filter is 3 kHz wide. Adam uses the 3 kHz roofing filter in the DUT (automatically selected in SSB mode in the FT-991 Transceiver)

Link to: Download the FT-991 RX NPR Test of 18/7/2015

A typical NPR test case emulates 1200 contiguous SSB signals, each at S9 + 30 dB. The higher the NPR figure obtained in the test, the better the DUT will be able to survive such extreme conditions. – The NPR test is also useful for identifying IMD choke points in a receiver front end, e.g. in RF steering diodes, and also passive IMD (PIM) in crystal filters, inductor cores and even some capacitor dielectrics.
I would categorise NPR ranges as follows: Measurement limit: ~ 95 dB (notch depth) / 85 dB and up: Excellent / 80-85 dB: Very good to excellent  /  75-80 dB: Very good / 70-75 dB: Good / 65-70 dB: Acceptable to good (source by Adam, VA7OJ – grazie!)
