Re: Bad USB OTG 'microUSB to USB-A' in zBitx shipment.
I had a similar experience.? Mine was black and did not work! Threw it away. Fortunately I had one already.

PLease do NOT add this item to further shippings as the quality can not be guaranteed.
I will have to next week for delivery of a good micro-usb to USB-A adaptor, rendering the zbitx useles in the box... Such a shame.

Re: zBitx Expected noise?
I am trying to see what is going on with your radio. ?I do not have that kind of sound from mine. ?The waterfall display looks like there is a weird signal there. ?Is your antenna connected? ?Do you have an external display hooked up to the HDMI?
?

My shared album contains a 14-second video. The radio is on CW, and there are no other connections. (Sorry for the bad lighting, I have not finished the system setup.

Re: zBitx speaker noise?
#zbitx
It clearly is the refreshing of the screen that is disturbing. There are more complaints, so I think Ashar will adress this problem.
I did NOT notice the flickering of the waterfall on the added (hdmi)screen, by the way, but then, it affects the sound too...

Re: zBitx Expected noise?
Got the same problem with the screen refresh...

I'll keep my eye out for updates and see what happens.

The stock sbitx mic doesn’t work well on an sbitx in stock form due to lack of drive. ?It does work on the zbitx as I have used it but the zbitx also suffers from lack of mic drive. ?
?
I have modded the stock mic with a new higher gain element as have many others. ?I think the details are in JJs (64 bit sbitx) wiki page. ?The modded mic works very well with the zbitx.

Re: polarity on power adapter 5.5X2.1 for the ZbitX
The barrel tip is a + positive voltage and the surrounding cylinder is the - negative.
I did a quick search looking for polarity and can find things on the Battery case but nothing specifying the barrel/tip of the connector for power to the ZbitX.? ?Does any one know what it is.? ?I have some connectors but don't have them with marked wires and looking to make me some to use.

Thank you

Paul Kelley, W4KLY, makes wood stands for Elecraft rigs and similar. He can probably provide a nice one..................

I assume the sBitx microphone would work. Is that an off the shelf item that can be purchased from somewhere else?
73,
Paul, N8HM
I would like an external microphone for the zBitx and a stand would be nice too. I would gladly pay for both as an accessory. Alternatively there could be an adapter for a standard microphone type, like Baofeng or Kenwood.

Finally, there could be an accessory heat sink since it seems the unit gets rather hot.?
Thanks for reviewing my thoughts. Again, I would pay for these as accessories. Certainly couldn't expect them given the very fair price for the radio!

Re: CW straight key sBitx and zBitx
Gordon
?? The sBitx performance above was seen with the 64 bit code. A lot of work went into making it work well. Someone will have to repeat that effort or just use the developed code.
? Also, the Pi 4B has four Cortex-A72 cores running at 1.8 GHz with 2-8 GB of SDRAM. The Pi Zero 2 has four Cortex-A53 cores running at 1 Ghz with .5 GB of SDRAM.
? All that said - the zBitx already has a very capable second processor in the Pi Pico that I think is just loafing along now. Several people have implements entire SDRs with the Pico. However, using a second processor to manage real time tasks would be a major revision of the circuitry.

Re: CW straight key sBitx and zBitx
So it looks like the workaround is to just send a dit before you get going; ?and set the delay long enough so that it holds in. You’re going to have to basically make it hold in for your entire transmission. ?So the delay needs to be long enough that it doesn’t drop out between words. It basically acts like a semi break in 7300 that can’t get the first dit out.?
We could make that work in a pinch, but I bet we can get this better!!! ? it’s not yet really clear yet why this isn’t as good as the sBitx , which has the same number of processors ??????
Has anybody tried Ron’s system for putting a processor dedicated to the transmission?

Re: zBitx Expected noise?
As a temp solution open the menu after you have landed on your desired frequency and operate with it left open. ?This will keep the screen from refreshing. ?If you’re on ft8 turn the volume down?. ?
