In order to use the RTL-SDR, the USB hub on the FT-991A must be upgraded from a 2-port hub to a 4-port hub, since the 2-ports were already being used for CAT and Audio. The FT991A is converted into an SDR.
Does Ft-991a Have An Antenna Tuner?
With its compact, lightweight package, the FT-991 is ideal for portable, mobile, and base installations. An eight-inch measurement. The dimensions are 8 inches by 3″ by 9 inches (W by H). With just nine inches (L), it is 9″ wide. With its full-featured mobile/portable design, this radio weighs only 7 pounds. This package includes an internal high speed automatic antenna tuning device.
When Was The Yaesu Ft-991a Released?
As of October 2016, the new FT-991A will be available.
Does The Yaesu Ft 991a Have A Built In Antenna Tuner?
Using a LC switching network, the built-in antenna tuner (for 160-6m) can be switched quickly and easily to reduce tuning time. A * 0 is standard on the FT-991A. The DDS/PLL local oscillator is designed to provide stable digital modes with a high resolution of 5 PPM.
Does Yaesu 991a Have A Built In Sound Card?
There is a built-in sound card in the FT-991, which some believe is the same as the sound card in the Yaesu SCU-17, Yaesu’s equivalent of Signalink. However, the FT-991 also supports FSK RTTY and CW. “So, the FT-991 has a sound card built in.
What Is A Panadapter?
Panadapters are devices that allow you to see the RF spectrum and waterfall being received by ham radios visually. In this setup, the IF output of the radio is connected to the RTL-SDR, and some settings are set up in HDSDR.
What Is An Antenna Auto Tuner?
In an automatic antenna tuner (auto-tuner), the load impedance is transformed (matched) to 50 resistive, and the matched condition is maintained automatically as the operating frequency and load impedance change.
Do You Need An Antenna Tuner For Receive Only?
Member. You will be able to receive better with your right antenna tuner. The radio will work better with a 50 ohm feed. It is common for antenna tuning to begin with tuning the antenna tuning by using the noise floor or receiving signal.
Is The Ft-991a An Sdr Radio?
There is no SDR in the FT-991a. There is definitely DSP-augmented tuning and filtering, as well as a slick spectral and waterfall display.
What Is The Purpose Of The Antenna Tuner?
In addition to antenna tuning (and any of the other names listed below), an antenna tuner is a device that is inserted between a radio transmitter and its antenna; when properly adjusted (tuned), it improves power transfer by matching the impedance of the radio to the impedance of the antenna, as it
Does The Ft-991a Have A Built-in Tuner?
The built-in antenna tuner has limitations. Only 3:1 of the SWR mismatch can be matched by the built-in tuner. In some cases, antenna components have intrinsic high impedances (such as G5RV or long wires, end-fed).
What Is The Difference Between Yaesu Ft 991 And Ft-991a?
Both devices also have a spectrum scope with an automatic scope control that is built right into the device. However, the FT-991a offers a real-time spectrum scope, which is the only difference between the two. By doing this, you can see the location of the incoming signal graphically on the band.
Does The Yaesu Ft-991a Have An Antenna Tuner?
This package includes an internal automatic antenna tuning device, as well as a high speed automatic antenna tuning device. In order to tune an antenna, the antenna tuner uses a LC switching network with a capacity of 100 channels. When a frequency is changed, the tuning data is memorized so that it doesn’t take as long to tune.
