Android operators won’t have to suffer the lack of good software anymore. it came with the case, HDMI cable, Samsung Evo memory card, the Raspberry Pi 3 B plus, usb card reader, heat sink, and quick start guide.Īs soon as I’m done with the current backlog videos, we’re going to do a headless Pi build and installation on the channel.

I’m using a Raspberry Pi 3 B+ kit, purchased from Amazon. The Raspberry Pi will be connected to the audio interface, and the Yaesu FT-891 CAT control port, turning our Android tablet into a full-featured Linux compatible Digital Comms Power House. That includes the digital modes we use with fldigi, wsjt-x, and I’m hoping at some point I’ll be able to run Wine for the single Windows app I use for HF aprs.

Headless RPiĪ raspberry piis a pretty inexpensive computer which we can use to install Linux Ubuntu to run headless, and control all of its functions through an Android tablet wirelessly. Until those apps are available to the public, we need to find a way to bridge the gap between the desktop and laptop worlds, and the ultra-portable tablet or smartphone world, one which almost everyone has and their pocket or backpack. Developers are stepping up to create new mobile apps for amateur radio, with better features than we’ve seen previously.

Thankfully there are some pretty cool things going on in the background. This attitude is killing the motivation of Developers who would like to make at least a little something for the effort they put into Android apps for amateur radio. Even if the app is somewhere between 3 and 10 bucks, the perception is “it’s too much”. Ham radio operators are cheap! We are willing to spend 700 bucks, a 1000 bucks, 2000 bucks on a rig, or 1200 bucks on an almost useless pactor modem, but we often don’t see any value in the time it takes to develop an app for Android.

2/3 rate K=13 FEC with 3.One of the biggest sources of frustration for the Android powered amateur radio operator, is the lack of apps supporting the most popular modes we find on Windows, Apple or even Linux computers.

1/2 rate K=13 FEC with 3.2sec interleaver.

1/2 rate K=15 FEC with 4sec interleaver.

modify edit code to maintain cursor position.correction to xmlrpc procedure to get smeter and power out meter from flrig.This seems to result in slightly better message decoding in marginal circumstances.Make the bit flip guessing a little smarter by correcting towards the 3/4 framing, but only if this character is only one off from a valid character.This is 'helped' by the 3/4 framing of SITOR-B, where every character has 3 marks and 4 spaces, resulting in the mark value consistently getting a lower envelope estimation than the space value, even when both are the exact same signal level! However, in the face of selective fading and QRM, the assumption of symmetry proved to be wrong.The flip_smallest_bit code was written with the assumption that the discriminator has equal weights for mark and space, that we are equally likely to get things wrong in each direction, and that flipping the bit with the smallest absolute value is likely to get us what might have been transmitted.make single bit flip correction guess a little smarter.adjust tracking filter constants to improve power detection.Fix cosmetic issues reported by Bob, VK2YQA.
