Is FM used on HF?
With the exception of a segment of the 10 meter band, FM phone is prohibited on the HF bands due to its large consumption of bandwidth.
Does FT-991A have an antenna tuner?
These FT-991A transceivers could not provide functions easier than at your fingertips with their 3.5 in. The integral internal high-speed Automatic Antenna Tuner included in the transceiver uses an LC switching network that has a large-capacity 100 channel memory.
Is the Yaesu FT-991A an SDR radio?
Thank you to Rodrigo Freire (PY2RAF) for submitting his project that has cleanly turned a standard Yaesu FT-991A ham radio into an RTL-SDR based software defined radio panadapter with no external wires, hubs or dongles.
What are the HF low bands?
What are we talking about?
| Acronym | Full Name | Frequency Range |
|---|---|---|
| VLF | Very low frequency | 3 kHz – 30 kHz |
| LF | Low frequency | 30 kHz – 300 kHz |
| MF | Medium frequency | 300 kHz – 3 MHz |
| HF | High frequency | 3 MHz – 30 MHz |
What is the bandwidth of HF?
HF radio operates in the frequency band 3–30 MHz. HF propagation and transmission techniques can be readily used down to 2 MHz and below. HF can be a very economic alternative for narrow-band, long-distance transmission. Up to 12-kHz bandwidth is permitted supporting four nominal 3-kHz voice channels.
Where are Yaesu radios built?
It was made in Japan. Don’t confuse the battery “made in China” label with the radio label under the battery. Even if it is made in China, it is made to Yaesu specs, nor CCR specs.
What is OmniRig?
OmniRig is a freeware CAT control engine used in over 50 applications. All programs that support OmniRig can access the radio simultaneously. Some Ham Cockpit plugins, such as Conventional Receiver, use this engine. If you install one of those plugins, make sure that you have the latest version of OmniRig.
What are the modes of the Yaesu ft-991a transceiver?
FT-991A transceivers include multi-mode operation on CW, AM, FM, SSB, and Digital Modes (Packet, PSK31, RTTY and C4FM), with 100 Watts of HF/50 MHz capability (50 Watts VHF/UHF). These superior-performance transceivers include a high-resolution full-color 3.5 in. TFT touch panel for exceptional operability and visibility.
What kind of RF amplifier does the ft-991a have?
The RF Amplifier in the FT-991A provides a clean and solid 100 Watts of Operating Power (50 Watts VHF/UHF) and is combined with a large heat-sink and forced air automatic cooling fan to increase operating time and prevent overheating. The FT-991 Comes in a compact, lightweight package suitable for portable, mobile and base installations.
Can a ft-991 be connected to a computer?
The FT-991 could not provide functions easier than at your fingertips with a 3.5″ Full Color TFT Display for Superior Operability and Visibility. The FT-991 can be connected to a computer using a USB cable for CAT control and firmware updates, or the use of an optional SCU-17 Interface Unit to support USB Audio In/Out, TX Control (PTT, Key, Shift).
Which is better the ts-590sg or the ft-991a?
The receivers in the TS-590SG & IC-7300 are somewhat better (IC-7300 is noisy though), but the FT-991A receiver is close to the IC-7300 & TS-590SG. The FT-991A has crystal clear receive audio plus has a great DNR. Downsizing, I sold the other radios and kept the FT-991A.
