USDX stablecoin depegged and after few hours still hasn't recovered! 🚨
Liquidations, stalled redemptions, and vault risks are piling up. What triggered the collapse - and can it be fixed? We break it down here: https://auriccrypto.com/stable/usdx-stablecoin-faces-major-peg-loss-protocols-launch-liquidations/

Based on the hard work of Adam, K6ARK I designed a PCB which does all the work of the connections and designed a case for it.
I think it looks like a Turret from the game Portal, hence its name.

Reading uSDX and BitBanger firmware code to figure out the shape of the signal fed into the RF amplifier. It’s a square, but what's the voltage range?
They control “SI5351 PLL phase through tiny frequency changes” and “PA Power through PWM on the key-shaping circuit”, says PE1NNZ. Does that suggest for CW the CLK frequency and duty cycle are stable and I can concentrate on PB2's PWM thumb on the gate of the switch? https://github.com/threeme3/usdx #truSDX #uSDX #RFBitBanger #OpenResearchInstitute

The major difference between the #uSDX and the ##FST3253 or similar commutating quadrature demodulator rather than a single phase demodulator. I decided not to use such a commutating demodulator because it requires a high speed analog switcher which is not necessarily easy to find in readily available parts...

I've looked plenty at the uSDX source code and it is quite possible to add something like #SCAMP to the #uSDX. The SCAMP demodulator would have filters for both in phase and quadrature phase and then select the sideband by adding or subtracting the two filters. It might be easier to port the #RFBitBanger source code to the uSDX hardware than adapt the uSDX source code to SCAMP...
Malaysian uSDX Owner Weekend 2023 with 9M4CPJ | Poster design by 9W2NSP Assalamualaikum and hello guys! Today, I’d like to share something related to amateur radio. A few days ago, I participated in an event called the Malaysian uSDX Owner Weekend 2023, which took place from the 28th to the 30th of July, 2023. This is an indie event organized by ham radio enthusiasts around Malaysia. The theme was set as the “Outing DXing Weekend,” during which HAM operators are encouraged to go portable by camping or engaging in other outdoor activities while operating QRP radios.
