I downloaded the app and installed it on my Doro Liberto 820 smartphone. However, the program author (Wolfgang Philipps) also offers apps specifically for RTTY and SSTV. It is not intended for regular base station use and is specific to PSK operation. It is unfair to compare this simple app with ‘full blown’ datamode programs such as FLDIGI. Has user-programmable macros for sending commonly used phrases.Produces a ‘waterfall’ display of the received signal spectrum to facilitate finding signals and tuning into them.Connects to the radio transceiver via the phone or tablets audio jack, or can be acoustically coupled to the microphone and speaker.Intended to work with Android phones and tablets.However, making the connection via the headset jack and a suitable interface would be a more reliable option. I use the term “connected” loosely here as it is possible to receive and transmit the audio tones via the built-in microphone and speaker in the Android device. Since I have an Android smartphone I thought I would I would give DroidPSK a try.ĭroidPSK is a simple program that allows text messages to be transmitted and received using BPSK (binary phase shift keying), via a radio transceiver connected to your Android device. It was suggested in the book that portable datamodes operation was a viable proposition using either DroidPSK (for Android phones) or PSKer (for iPhones).

The only major disadvantage of Flamp is that it is not compatible with Andflmsg if all net participants are using desktops or laptops, there is little reason not to send forms over Flamp.Ĭopyright © PBARC Wiki contributors. Flamp can be used to transfer Flmsg forms. With long messages, this can drastically reduce the time to successfully transfer a file in less-than-ideal propagation conditions. If the entire message is not received, only the parts that were not successfully received need to be re-sent. It breaks the message into blocks (somewhat similar to packets, for those who are familiar with IP or AX.25 packet switching) with error detection codes. When a form is received, it can be converted into a printable HTML document.Īndflmsg combines the functions of Fldigi and Flmsg into an Android app.įlamp is a file transfer program that works using Fldigi as a modem. The files do not have to be sent over radio they can also be emailed or sent by any other means of file transfer. When they are received, the receiving station can load the data into its copy of the form, speeding up transfers by avoiding the need for transmission of the entire form. Fldigi, Flmsg, and Flamp are used on the ORCA Digital Net.įlmsg allows the user to enter data into predefined forms, which are then sent over radio. Several other programs are available for use with Fldigi. An Android version, AndFlmsg, is also available, although it has limited features compared to the desktop version. Fldigi is a sound-card digital radio program for Linux, Mac, and Windows.
