Same frequencies as for RTTY 45 bauds (Ham), in particular around 14075 KHz. SITOR A (ARQ) or SITOR B (FEC) (commercial) (USB, examples) 4210-4218, 6314-6329, 12579-12646 NAVTEX (commercial) (USB, examples) The NAVTEX frequencies are 518 et 490 Khz. The user will set their transce...
Operators experiment with antennas, frequencies, and modes, connecting with fellow hams worldwide. Beyond the technical aspects, amateur radio serves as a vital lifeline during emergencies, providing communication when other systems fail. Looking Ahead As the amateur radio community continues to grow, ...
and some were saved on our own internal storage. Managing projects was a pain, even more so if the projects had some parts using licensed frequencies. (in which case, most of the time, the unlicensed part of the project would be stored somewhere, and the licenced part somewhere else) Now...

Access to lower FM band frequencies (88.1 – 91.9) that the FCC reserved for use by colleges, community and public-radio organizations and tribes; entities that the FCC envisioned would have limited funds to acquire these frequencies, and commercial broadcasters were banned from bidding on, but ...
the transmitter will only communicate with that specific receiver. This means that other pilots in the air usually don’t interfere with your radio link. Additionally, the radio signal will hop across different frequencies within the 2.4 GHz band to ensure a strong and uninterrupted connection betwe...
Because a scanner can receive a huge range of frequencies, you can set it to receive nearly anything on the air. In order to use a scanner, it's ideal to have good frequency tables so you know where the action is. For more information, check out the links on the next page. Lots ...
However, the typical software defined radio used is an RTL-SDR, which cannot reach S-band frequencies like 2.2 GHz where most S-band satellites transmit. To get around this, we could add downconversion circuitry to the S-band feed, which would increase complexity and cost. This would convert...
Rather unassuming in appearance, the PR-D12 receives AM/FM and NOAA Weather Band frequencies and offers the Weather Alert feature which can be a lifesaver if you are in an area threatened by dangerous weather conditions. We’ll check it out, compare it with some reference radios and see ...
One feature I particularly like is the multifunction tuning knob. Rotating the knob does as one would expect in changing frequencies, and pushing the knob in switches between fast and slow tuning depending on the band. But a third option is “Stop”, which locks on to the frequency such th...
