🚨 Totally Real Announcement (Seriously?) – Digital Baseband V2.0 🚨
Before you scroll past thinking “ah, classic April 1st nonsense”…
Give us 10 seconds. 😄
We’ve been tinkering, experimenting, and possibly bending reality a little…
And somehow ended up with this:
🎉 Digital Baseband V2.0 🎉
What’s new? Oh, nothing special… just:
👉 Direct SDR-to-RF FM-ATV modulation
Straight onto frequency. No detours. No magic boxes. Just your SDR doing its thing.
👉 Wide frequency coverage: ~400 MHz to 6000 MHz
Because choosing bands is overrated anyway. Why not all of them?
👉 Control via the Digital Baseband screen
Yes, the same screen. No extra knobs, no extra apps — just tap, configure, transmit, and question your life choices.
👉 Includes Itch-free SDR™ mode: clinically proven to eliminate delay-induced frustration.*
*(ODJ-Approval-proof)
At this point you’re probably thinking:
“This is obviously fake.”
We agree. It sounds fake.
It reads fake.
It was announced on April 1st…
And yet…
👉 It actually works (we think)
So while the internet is busy with flying pigs and quantum rubber ducks, we’re casually dropping something that should be a joke — but isn’t.
Obviously it’s new software V2.0 for your existing Digital Baseband. You will need some additional hardware:
…and of course a suitable SDR…
Try it. Break it. Enjoy it.
And don’t worry if your SDR looks confused… we were too. 😅
Coming soon… watch this space for updates!

We will post a technical description of the inner workings of the Digital Baseband on this page.
The Digital Baseband is realized in a Field Programmable Gate Array, or FPGA. An overview of the hierarchy and components comprising the FPGA will be included. This Digital Baseband incorporates a NICAM encoder which is based on the NICAM encoder Werner developed back in 1999, with the help of Willem PE1PCF. That encoder used a Digital Signal Processor (DSP) in conjunction with an FPGA, and required external filtering to shape the NICAM modulate.
Since the FPGA used in the Digital Baseband is roughly 200 times more powerfull than the FPGA used in the original NICAM encoder, the DSP and external filters are no longer needed as the FPGA can easily perform these tasks.
One of the production steps is that the BGA’s are inspected using X-Ray technology. Here is a capture of such an inspection.
The digital baseband offers pre-emphasis and steep 5MHz filtering (without any C/L delay issues), NICAM, 4 FM channels, text overlay (for call and so on), morse code generator (for call and so on) and some test cards and a bessel null function to align your FM transmitter. As per version 1.4, the first 8 characters of the morse code ‘MSG’ are transmitted in the additional databits inside the NICAM data. This allows nicam decoders to display your station ID (CALL). All is controlled by an ESP32 with a 320×240 display. See the manual section for more details.
November 2024 update: new boards are incoming! You can contact us if you want to buy one.
If your digital baseband is broken, kaputt, stuk or just doesn’t work, please contact us! We will do our best to solve the problem for a friendly price.
October 2025 updates:
- All boards are sold out.
- A new firmware version has been released (v1.4)! See the announcement in the download section.
- A document “Reading the station ID from NICAM using the MSP34x5G” has been added to the software updates section
