What frequency is used for PSK31?
What frequency is used for PSK31?
PSK31 Frequencies
| Frequency | Amateur Band |
|---|---|
| 7.040 MHz* | 40 meter (regions 1) |
| 7.070 MHz* | 40 meter (regions 2) |
| 10.142 MHz | 30 meter |
| 14.070 MHz | 20 meter |
What is the ideal bandwidth of a PSK31 signal?
approximately 60 Hz
PSK31 is a digital communications mode which is intended for live keyboard-to-keyboard conversations, similar to radioteletype. Its data rate is 31.25 bauds (about 50 word-per-minute), and its narrow bandwidth (approximately 60 Hz at -26 dB) reduces its susceptibility to noise.
Is PSK31 dead?
PSK 31 is still alive and well. I notice a fair amount PSK31 activity on 20m (14.070 MHz) on the weekends. If you enjoy keyboard chat modes, try JS8Call. It’s quite nice.
How do I get PSK31?
To get started sending and receiving PSK31, you’ll need an HF rig, a computer, and a way to connect the two. Typically, this will be done using an interface, such as the one pictured below. This sits between the PC and the radio, and handles the audio, tuning the radio, and setting the radio into transmit.
What are the Wspr frequencies?
Frequencies in use for WSPR
| Band | Dial freq (MHz) | Tx freq (MHz) |
|---|---|---|
| 80m | 3.592600 | 3.594000 – 3.594200 |
| 60m | 5.287200 | 5.288600 – 5.288800 |

| 30m | 10.138700 | 10.140100 – 10.140300 |
What is the 10 meter calling frequency?
28.0-28.5 MHz
10 meters is unique—the band from 28.0-28.5 MHz being where all licensed US radio amateurs from Novice through Extra Class have voice and digital mode privileges.

Is RTTY still used?
However with the arrival of computers and their greater level of flexibility and sophistication, other more efficient types of digimode are available but despite this, the amateur RTTY is still widely used.
What is JS8 mode?
JS8Call (JS8) is an amateur radio QSO communication mode based on FT8. It is popular among amateur radio operators for its ability to send and receive messages despite challenging propagation conditions, high noise environments, low power operations (QRP), or even compromised antennas.
What is ham FT8?
Unlike JT65 or JT9, transmit and receive cycles in FT8 each last about 15 seconds. Like JT65, FT8 requires accurate time synchronization. An auto-sequencing feature offers the option to respond automatically to the first decoded reply to your CQ.
Where can I find RTTY signals?
RTTY signals can be found on all HF bands – check the band plans and tune through the “Digital Modes” segments. A number of different modes are used in these band segments, but these modes can be distinguished by ear: RTTY signals are characterised by a regular shifting back and forth between two tone frequencies.
What mode does WSPR use?
MEPT-JT
WSPR was first released in April 2008. It uses a transmission mode called MEPT-JT. MEPT stands for Manned Experimental Propagation Transmitter and the JT represents the initials of Joe Taylor himself which also appear in his callsign.
What are the frequencies of a PSK31 radio?
Next, tune your radio to a common PSK31 frequency; two are 7.070 MHz and 14.070 MHz (see a full list of frequencies below). Make sure your radio is set to SSB mode on the upper sideband (USB).
Can a PSK31 be set to SSB mode?
Make sure your radio is set to SSB mode on the upper sideband (USB). Your will not have to change frequencies after that, since PSK31 signals are so narrow (31 Hz), all the transmissions will be picked up by the receiver without changing frequencies. It is then up to the software, not the radio, what signal (s) to decode.
Where do PSK operators hang out on the frequencies?
PSK operators tend to hang out at certain frequencies on the bands. Some of the frequencies are dependent on the location of the station, due to local regulations or QRM. Here are the most common:
Which is better a PSK31 transceiver or antenna?
Obviously, the better the transceiver and antenna, the better performance will be achieved, however PSK31 performance is often virtually the same on both low-end and high-end equipment. The only major requirement for the computer used to send and receive the PSK31 signals is that it contain a soundcard.
