There was a ham here who found a 2MHz spur coming out of his radio, and also spurious signals 2MHz up and down from his desired signal. He was pretty adamant that the level was above FCC allowances by

Thanks Dave -- the only concern I have about these switching power supplies (I bought a few but haven't used them yet) is generation of radio frequency interference. The noise level of the zBitx may

Instead of all the diodes get a Drok voltage/current controller from Amazon or other places. I can then use the battery packs from my yard power tools and reduce them down to whatever voltage I need

Tony, I just purchased one (a zBitX) at Dayton (FDIM, the QRP Meeting) and have tinkered with it learning everything I can. The bands have been less than stellar but everything seems to work well for

I've had mine for several weeks now. I think it's an amazing radio. That it's open source just means there's more than just Farhan fixing bugs and extending its capability. There was an issue with

I agree with Franco. If what he writes doesn't apply to you, get a G90. 73 DF7II Jürgen

Hi Tony, I ?ordered the Zbitx just yesterday, despite having read all the reviews and all the problems. This is because I would like an RTX that ?I can get my hands on, in terms of both the

So, the Zbitiz has been out for a minute. Would you all that have the radio say it is safe to buy with no major issues? Read a few reviews that stated some issues with the unit. I know nothing is

Rafael, I would take a 12 V laptop power supply from a thrift store, and then add a bunch of series 5 or 10 amp silicon diodes until you get the voltage down to about 8 V. Six diodes in series should

Could anyone recommend an affordable power supply I can use with the zBitx, to use with 110 or 220 VAC, 50Hz and 60Hz? Cheers, Rafael

There are some high output (e.g. -28, -30 or -32 dB ) electret cartridges that I've had good success with (and can be found in the WIKI) but a mic that has worked well for me is actually a powered

Thanks all.? The internal seems to be working but pressing a button in my hand will be much easier the fussing with the touch-screen.... -- "POWER, WE DONT NEED NO STINKIN' POWER" - Every KX2 Owner

I'm working on a adaptor cable(s) from a Kenwood HT Type Microphone to the zbitx, I just received the cable I needed in the mail this week, will try to work on it soon. [email protected]> wrote:

The input of the zbitx microphone is the same as the input of the sbitx microphone, so I would only use a microphone with an amplifier. Check out the forum posts about microphones. The description of

Gary, You can use any mic that works with any Bitx, currently I use these, https://www.qrpkits.com/microphone.html ,but I also use the mics that came with all my sBitx's, pretty much all of them work.

I'm currently working on an adapter for an extra Yaesu MH-31 I have (just for the voice and PTT, not extra buttons)... I think it should work, but I'm not finished yet. Will report back.

BitXers? ??? Someone have a link for a decent low cost mic for the zBitx?? All my mics are Kenwood or Yaesu.? They wont work of course.? I am assuming any standard 3.5mm plug microphone will

Thank you Jody for fixing the iambic keying problem. It works great now. The only errors seen are the ones I myself generate! I am a 70 year old tube radio doctor (licensed as WN1NUU in 1970) and have
