Re: zBitx Expected noise?
Robert,
?
You may be on to something here, I setup my zBitx to the exact parameters as your is set and noticed a marked reduction of display chuffing, it's still there but way better. If I turn the IF gain up to 39 is comes back, reduce it back to 38 it gets way better, the waterfall being almost perfectly clear, all this being done with out a antenna connected of course. Now when I switch to 40M it's still fairly quiet. For the time being I'm going to leave the IF gain set to 38 or below and see how things go. I have to ask myself why one increment higher would add that much noise to the radio.

Re: Bad USB OTG 'microUSB to USB-A' in zBitx shipment.
Mine is black and works fine, I guess it's hit or miss on the OTG adapter. HFSignals need to supply a better quality adapter.

Re: zBitx Expected noise?
I set same parameters as Robert (shown in his video).
I have extremely quiet radio (on 9V switching, external power
supply).

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 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...

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.

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.
A stand should be steady so that the internal keyboard can be used. I was thinking along the lines of the KX2 with arms that rotate on the side.
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!
