Waterfall and CW decoder on/off
The receiver noise would go away if the waterfall could be stopped. Could someone put a "Wfall on/off" icon in the SET or MENU functions that would stop the waterfall. It would be nice if the CW

Re: Failure on first use?
The qrper.com review of zbitx ( https://qrper.com/2025/04/first-look-at-the-hf-signals-zbitx-qrp-transceiver/ ) says: Your fifteen minutes at 4.5W would mean the batteries were asked to deliver 60

Zbitx Mic(HT) Wiring
Built this wiring harness this afternoon to convert a HT Mic(Kenwood connector style 2.5mm/3.5mm) to the Zbitx, and I assume it would work with the sbitx. The microphone's speaker is amplified, I

Re: First Satellite Downlink Reception over sBitx (for me at least)
Unfortunately, SATPC32 does not appear to be able to do CAT control via Hamlib (otherwise it would be easy to control the sBitx)? -- but it can control ICOM type CIV on "Radio2"? ? Unfortunately,

Finally I can Boot zbitx From USB
I finally managed to boot from an external USB on my zbitx. I had to modify /boot/cmdline.txt? on the internal sdcard to point rootfs to the external device UUID. Of course if I remove the external

Re: First Satellite Downlink Reception over sBitx (for me at least)
Great advice, Dave! The loss through the coax is considerable and I should reduce that length and improve that problem. As for power output I haven¡¯t measured it, supposed to be better than 30 W.

Re: zBitx +-2 MHz transmit spurs? --> SHOWSTOPPER for transmitting
What interesting to me...? is I've been following this. This is a rerun of the same issue for uBitx V3 series, Sbitx, and appears here now. General issue is pushing transistors for more gain (not

Re: First Satellite Downlink Reception over sBitx (for me at least)
Gordon, Sounds like great progress. Sadly I got rid of my transverters a couple years back when I bought a IC-9700, so I haven¡¯t tried using my SbitX for satellite work. I did experiment with using

First Satellite Downlink Reception over sBitx (for me at least)

Re: zBitx +-2 MHz transmit spurs? --> SHOWSTOPPER for transmitting
Hi Gordon; Yes - a tuned circuit at the emitter bypass of Q3. LTSpice simulation suggested replacing C22 with 150 pF and R33 with a 100 nH chip inductor. This combination does appear to work, with a

Hi Gyula; Thanks for your suggestions. I do need to look closer at the power filtering to this part of the circuit. Keeping the stray RF out of the buffer stage could possibly be more effective than
