CW with Bluetooth iambic paddle remote from mobile with near-zero delay? Yes, it is possible! New Ham Mixer Mobile feature. https://t.co/9gUJrkDNfA 73 DE CT7BAC #CW #HamRadio #HamMixer

ARRL contest update: while waiting for my daughter at padel, worked WS7X remotely using HamMixer Mobile. In this clip I overlay the screen recording audio so the QSO stays readable in that heavy noise. Check it out! https://t.co/9gUJrkDNfA 73 DE CT7BAC #ARRLDX #HamRadio #HamMixer

Worked 9A8DX while waiting for food at a restaurant 😄
That’s the flexibility I wanted when I designed HamMixer Mobile!

Desktop workflow: radio + WebSDR, time-synced, all-in-one screen.
Excellent for enhancing signals in noisy conditions for casual QSOs.

Mobile remote QSO, solid TX audio.
Check how I shape my TX audio on mobile so it stays clean and punchy.

Coupe du REF is on fire today 🔥🇫🇷
Even away from the shack I’m still active from my phone and logging QSOs.
This clip is how I’m operating right now.

Quick real-world demo: me working W1AW from mobile using HamMixer remote operation.
Raw screen recording, no edits — just practical ham radio workflow in the field.

More real clips coming (CW, DX, logging workflow).

Back on X after a long break.

I’m a ham operator in Braga (CT7BAC) and I’ve been building HamMixer from real station needs: better RX in urban QRM and practical remote operation.

I’ll share real-world clips, QSOs, CW workflow and technical notes.

@AnthropicAI Any perspective of opening the beta website to European countries? I am from Portugal and would love to test it. Thanks!

[Pedro Silva @CT7BAC]

The research is ongoing... Just some setbacks with the hardware, but we are back in the game. Some data from different take-off angles. Still a lot to work on, but we are in the right path. The final result may bring a fresh panorama for antenna owners (not only hams).

[Pedro Silva @CT7BAC]

@rpilocator The problem @Raspberry_Pi is that the amount of people loosing patience and running to alternatives (plenty of'em) is growing bigger daily. Not everybody has stomach to buy in this "black friday" fashion. I am almost there...

[Pedro Silva @CT7BAC]

@rpilocator This batch lasted for a longer time... 90 seconds! Thanks @Raspberry_Pi for making us feel so good trying to buy your lovely, yet rare, products...

@eevblog In Portugal i don't hear this word COVID for a long time... On TV, no way!

[Pedro Silva @CT7BAC]

@rpilocator What? When? Tweet from 2 minutes ago. Let's see:

[Pedro Silva @CT7BAC]

@rpilocator 100pcs... Not even a tickle on the demand. All stocks replanished all over the world don't last for 30 seconds. So far, the problem (to me) remains the same. Sad, but true.

[Pedro Silva @CT7BAC]

Next flight: measure takeoff angles of 15°, 45° and 75°. How the radiation patterns will look like? Will i have drone batteries enough($$) some day in future to make measurements in many takeoff angles, say every 5°, and generate a 3D plot? Will see...

[Pedro Silva @CT7BAC]

@rfsparkling @F5OEOEvariste First trial. Not bad. Drone struggling, one part of the graphic should be "ignored", for now. Looks promising. Next step: more trials and different heights, to form the 3D plot. Will it work? Will see...😂 #drone #SDR #radiationPattern

[Pedro Silva @CT7BAC]

@rfsparkling @callummccormick @F5OEOEvariste Nice! My research is focused on characterizing big antennas radiation pattern. Let's see where it takes me...😃

[Pedro Silva @CT7BAC]

Is that a bird??!! Is that a plane??!! No!! @callummccormick @rfsparkling @F5OEOEvariste
That is the Radio-Drone!! Further details of this experience will be published soon...😉#hamRadio #propagation #SDR #drone

@Raspberry_Pi @EbenUpton I think you guys should focus urgently on having available stocks before anything... A LOT of people giving up on RPi due to neverending shortage. The option to buy an used RPi4 from scalpers at gold's price is not joyful. Q2 2023 is upon us. Where are the RPi 4?
