60 Meters consists of five discrete channels rather than a continuous band of frequencies like the other Amateur Radio bands.Įach Amateur Radio Band above is divided into sub-bands where various modes of communication, transmitting power limits, and license requirements apply.The upper portion of the 80 Meter band also is known as 75 Meters.Radioteletype evolved from earlier landline. On the HF bands the carrier for the RTTY signal is shifted between two frequencies, and this gives rise to differing audio tones when a beat frequency oscillator or BFO is used.

These machines were later superseded by personal computers (PCs) running software to emulate teleprinters. In turn these are represented on the radio signal by a shift between two frequencies, one frequency signifying a mark or high voltage and another frequency representing a space of a low voltage. NCDXF Beacon is a simple tool to help you monitor the NCDXF beacons on the Ham Radio bands 20m, 17m, 15m, 12m and 10m.Upon start the the time will be synchronized with an NTP server and the status of the beacons will be checked from the NCDXF website. Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. A long click on a button will record a message and a normal click will play it back. The messages are easily accessible though 6 buttons. Voice Keyer is an audio recorder tool to record and play back messages. This app was originally programmed for Ham Radio operators to remove unwanted background noise and improve SSB and CW signals.ĭTMF decodes and encodes DTMF (Dual-tone multi-frequency) tones trough the phones speaker and microphone.Įncoder: Always 2 tones are assigned to each key.The length of the tone and the pause between the tones can be set from 35ms to 1500ms. The DSP Audio Filter is a tool that enables you to filter frequencies from an audio spectrum by using your cell phone’s microphone.

A narrow band DSP filter can be set for the frequency of the Morse code tones by tapping the waterfall. Morse Decoder includes a “waterfall” to show a frequency spectrum.

Morse Decoder decodes Morse code characters through the built-in microphone of your Android device. The app runs in the background as a service and alarms you with a ringtone of your choice when a callsign or prefix appears in the DX Cluster. Get live DX spots on your Android device.DX Cluster’s focus is on alarms and real time spots.
Just slide the waterfall slide on a RTTY carrier frequency and DroidRTTY will decode the signal. This mode is gradually dying out in favor of more robust modes like PSK31 in the amateur service. WIKIpedia definition: What is RTTY radio RTTY Radio TeleTYpe (Also known as Baudot or ITA2) uses the Baudot 5-bit alphabet with FSK Frequency-Shift Keying. Just slide the waterfall slide on a PSK carrier frequency and DroidPSK and decode the signal.ĭroidRTTY is an application to decode and encode Ham Radio RTTY with the build in microphone/speaker or wired to your radio.Ī waterfall shows the frequency spectrum of 100Hz to 2000Hz. RTTY Radio TeleTYpe (Also known as Baudot or ITA2) uses the Baudot 5-bit alphabet with FSK Frequency-Shift Keying to send text messages over the shortwave. A waterfall shows the frequency spectrum of 100Hz to 2500Hz.

This communications app is a great tool for portable amateur radio SSTV operationĭroidPSK is an app for Android to decode and encode Ham Radio BPSK31& BPSK63 with the build in microphone/speaker or wired to your radio. With a lot of settings it is very comfortable to adjust Morse Trainer to your current level.ĭroidSSTV lets you transmit and receive amateur radio (ham radio) slow scan TV (SSTV) on your Android Smartphone or Android tablet. Learn or improve Morse code with Morse Trainer.If you are a ham radio (amateur radio) operator or just want to learn morse code. Test transmissions are authorized above 51 MHz, except for 219-220 MHz. There is dedicated equipment to receive RTTY and SITOR but we can receive both using a standard HF/SSB receiver with software packages such as TRUETTY, JVcomm. RTTY and data phone and image SSB phone CW only USB phone, CW, RTTY, and data Fixed digital message forwarding systems only KEY Note: CW operation is permitted throughout all amateur bands. Ham Radio apps developed fro Android phones and tablets A similar service is the USCG service, SITOR (Simplex Teletype Over Radio) providing offshore and coastal forecasts over very wide and remote areas from the tropics to the polar regions.
