9/10/2023 0 Comments Fldigi on raspberry piOtherwise a yagi directional antenna and tower could provide a strong enough signal without a repeater. Some FM repeaters might have sufficient bandwidth to give you 50 mile coverage. You might also look at the low cost (~$30) Baofeng (or similar) 2m/70cm HT's that could probably transmit in MT-63 mode with only a microphone and speaker on the Pi held close the the HT. Most SSB transceivers are somewhat more expensive, but by using the more advanced digital modes instead of CW, you could greatly improve accuracy and speed in difficult propagation conditions. The low cost "Pixie" transceivers only do CW, but could be "keyed" with an cheap transistor using the circuit included in the fldigi documentation. These non-CW modes rquire a SSB transceiver though. Each transceiver would require a bidirectional audio interface, such as a low cost USB sound dongle. It can also be programmed to transfer email, formatted and pre-canned messages both in keyboard to keyboard and automatic mode. You might have to rig up some form of CW keying alsoįldigi can run a multitude of digital modes including CW, PSK and Olivia. Groups.A Raspberry PI (preferrably a model 2) could run "fldigi", a free open source digital mode software. Raspberry Pi Explained support group for the book and all things Pi.Mike’s web page for ready-to-use SD cards and Raspberry Pi blog.Watch Mike’s 2017 Convention lecture Pi in the shack Assuming youre logged-in at the base of your home directory (well use username pi for the sake of this answer) First well download and extract the file: On your Raspberry Pi, download this Linux3.x.x4.x.xVCPDriverSource.zip (well assume it goes into your /Downloads folder).Also note that any software listed here is downloaded at the reader’s own risk, and the RSGB is not responsible for any unwanted effects arising from its use. You can also use the GPIO header on the RPi for serial communication. You can connect your RPi to this which then usually appears as /dev/ttyUSB0 or similar device. Either with a built inn USB-to-Serial interface or with an external connectors. Please note the RSGB is not responsible for the content of external websites. Most radios (including the FT817 and FT857) have serial rig control. His latest endeavour has been the well-received book Raspberry Pi Explained for Radio Amateurs, published by the RSGB.Ĭheck out Mike’s book – Raspberry Pi Explained for Radio AmateursĪvailable now from the RSGB Shop Find out more Mike’s writing career began some 25 years ago when he took over the PW RTTY column from Ron Ham and has been writing reviews and regular columns for many radio magazines including RadCom. That spurred him on to get his Full licence, G4WNC, where he has maintained an interest in digital modes. Following a 42-year career with BT, Mike-who was first licensed as G8HHA-turned to computing in the early 70s where he experimented with radio data links between his Compukit UK101 and a friend’s TRS-80. Mike has been involved in radio and electronics since his childhood days. Well-known expert Mike Richards, G4WNC sets out to provide the basics of the Raspberry Pi, alongside making them work in an amateur radio context. However, they have become extremely popular and are selling well outside the original target market including in amateur radio. The Raspberry Pi series of low-cost single-board computers were developed to promote teaching of basic computer science in schools.
