The Coolest Radio You've Probably Never Heard Of

Work wouldn't allow me any time to work on other projects thanks to a botched go live. Tonight, I opened up Claude Code and found a test plan with over 40 tests to complete. Talk about detailed. Also was curious how much the project has grown since I forked it from JJ'S son's account. Apparently we've added about 30% line wise to the codebase, most of it in csharp. That's about 7000 lines. The setup and executables haven't changed at all, if anything 32 bit got smaller after the Dotnet 8.0 migration. It's all signals green and up from here friends. #JJFlex #HamRadio #sdr

I've been trying to demod FT8 on my SDR for a few days with no luck. Suddenly, wow! It works!

I am SUCH a nerd!

Chi phí SDR thực sự cao hơn bạn nghĩ: $110k–160k/năm, thời gian hòa nhập 3–6 tháng, chỉ 17% đạt doanh số. Khi họ nghỉ, kiến thức về khách hàng, phản đối, chiến lược… mất theo. Giải pháp: 6 AI agents chia sẻ 1 bộ não, học từ mỗi cuộc gọi. Sau 100 cuộc, AI dự đoán phản đối tốt hơn con người. Chi phí cuộc hẹn: $50–80 so với $400–600. Kiến thức không bao giờ nghỉ việc.

Tonight I'm seeing what appears to be really spread out FHSS on the 31 meter broadcast band. There right along with the braodcast stations. It doesn't look like the pips themselves are interfering with the broadcast stations.

Playing around with ctcss squelch block analog.ctcss_squelch_ff(self.audio_rate, 131.8, 0.10, 0, 0, False)

It works, but sometimes short cracking noise when there is no carrier with 131.8

The default 0.01 gave continue noise, but 0.11 kills audio even if the carrier is there. Maybe the latter 3 parameters should be adjusted? Wiki block docu is limited.

LinHT 2/2

It combines modern RF hardware (SX1255 with a power amplifier) with a general-purpose SoC (i.MX9352-based), making it closer to a pocket #SDR computer than a classic walkie-talkie. It is a truly all-mode radio that we all have been waiting for.

Who has never wanted to see radio spectrum waves with their own eyes?

Here is a setup that combines an SDR receiver and LED filaments.

SDR / DSP Devroom
—————————————————

@gnuradio is not the only #SDR project out there, but it is present in several of the talks:

https://fosdem.org/2026/schedule/track/sdr-dsp/

The room organizer is a Jean-Michel Friedt, who people in the European GR community could (and maybe should) know.
People regularly tell me they'd pay good money for "the JM Friedt show", that is, his entertaining, fast-paced presentations, so this is really anything but a secret gem of #FOSDEM :)

One thing I like about the #SDR #FOSS community far beyond just @gnuradio : it's very social!

GNU Radio will be at @fosdem 2026, hoping to see everyone around!
1. at the #GNURadio booth in building AW
2. at the GR beards-of-a-feather on room H.3242, Saturday 14:00–14:55
3. at various talks at the Software Defined Radio(SDR)/Digital Signal Processing(DSP) devroom on Sunday, Room K.3.601

14GHz per second?
What does that mean? GHz is already a measure per second.

Having a full-spectrum band scope is a game-changing feature for contesting. Immediately answer the question "what bands are active?" And then zoom in to a waterfall as wide as the band and just click around to the activity you see to make contacts. This was my first time operating my Hermes Lite 2 HF SDR and it was pretty dang nifty. #hamradio #winterfieldday #sdr

Hi unknown neighbor. Your weather station is my weatherstation thanks to rtl_433. Thank you.
