I have now gotten an elevation system working very well using a linear actuator (12V) from Amazon.? ?Also created crossed yagi's to allow for circular polarization.? ? Using "J" half-folded dipole

I think the RIT got turned on in the second photo (off in the 1st) as I was playing around trying to fix that display offset error. It made no difference. However, I did get the odd frequency fixed in

I agree and would like to add. It is also possible that due to the higher load, the transmission will be noisy (50hz) which will degrade the sound of the FT8. HA8LKT Laci HA3HZ via groups.io

Exactly. The current consumption during transmission is higher than what your power supply can handle, which is why the voltage drops. The device turns off due to the low voltage, as it drops out of

For low power you need a well-radiating antenna, then you will be successful in the connection. It is advisable to call the CQ station and not the other way around that you are CQing, then the QSO may

If I recall correctly, the USB-C PD standard is 9V at 3 A max. I suspect when the zBitx transmits, the current draw exceeds 3 amps and the PD adaptor shuts down and then restarts.

Yeah, I ran into the same issue with that OTG adapter. I think it's not so much an OTG adapter as a crisp, tasty waffle. I had one around, and, like you, got my keyboard and mouse working. Then I

BitXers, ??? Been playing with and learning my new zBitx and I am having a blast.? I have made a couple CW contacts almost immediately after receiving my unit.? I had a couple unexpected hiccups

So if we are talking about the HRCC video and how his radio was resetting, he posted a follow up video and admitted that he used a 1A power supply. When he connected a 3.5A power supply, problem

Hi Jody, New user/developer here and just tipping my toe in the water.? Regarding debouncing the key interrupts I wonder if you tried or considered disabling the GPIO interrupt as the first action in

John, How do you know yours is truncating TX in FT8? I did completed some QSOs but success rate is very low. For me it seems it transmits fully judging by the losing of waterfall (all striped yellow

I’m using a PD power supply that comes with my MacBook computer along with a 9v trigger cable rated at 5 amps. But I cannot set Drive beyond 60 with FT8 on 20 meters. If is over 60, the zBitx

I haven't received my zbitx and haven't had my hands on it yet, so maybe my question is moot. With inexpensive and reliable GPS Modules such as the GT-U7, is there a way to implement it into the zbtix

Hello, I have the same “chugging” sound on my ZBitx. I haven’t tried this yet ?but if the sound is diminished when the headphones are connected, I wonder if an external speaker would get rid of

Shielding between the display and the RPi and shielding of the flexible connecting wire. For sbitx I use copper foil and Kapton foil as electrical insulator because it can withstand temperatures

On the zbitx, the RIT switch is in the ON position, is this intentional? -- Gyula HA3HZ

Hi group, Doing some FT8 with my zBitX using the built in FT8 software. Generally working fine, but I noticed an anomaly on the device display of decodes vs the RPi desktop display of decodes in the
