Hi ETAPRIME!!!
I absolutely love your?channel!! I hope Ashhar decides to send him a unit. I'd love to see what he says about it. And he's got a lot of subscribers. It's cool he's wanting to review this.

Joel, The ones not yet shipped will be shipped with the updates applied. They should go out this week as well. - farhan

Sure, it'll work fine. Pick an electret mic type that Ashhar has
blessed, and adjust the mic wiring appropriately.
I think you can put the DC voltage onto the "hot" audio lead of the
3-wire XLR interface.
I've never tried it but I happen to have a rather nice XLR mic and
audio processing unit that came in a station purchase, and when I prep
my Heath DX-100 for operation, I'll definitely use this mic when I'm
not using one of my Astatic D-104s with a new electret element.
I'd mention -- back in the day I made a 5-pin DIN mic switchbox so I
could test and use all the old CB mics I'd collected over the years on
my Atlas 210X. Being able to switch mics on the fly was fun, and it
sometimes confused toe ham on the other end of the QSO.

Allison,
Thank you for responding.??I did remember the discussion.? That was before the latest announced changes to the TR switching.? ?I was checking to make sure the 2n7000 was still needed.? Per the prior information provided, I thought it was still a good thing to have.
Maybe Farhan will update the schematic with both of us commenting.
As always, I appreciate all of the free knowledge that you share.? It helps me learn more about RF circuits and RF design.

Evan,
pet peve, schematis do not match the board.?
the 2n7000 is the complment of the pmos switch that ensbles +12 to the tx bias. The nmos part is used to rapidly pull that line to ground. ?
It was discussed maybe 3 months ago.?

Farhan, On the sBitx that I received, there is a 2n7000 MOSFET soldered on the underside of the main board.? I have not been able to find it on the schematics.? Is it required?? If so, the schematic should be updated.? Here is a picture I took before I removed it when it was blown with my failed software-based sequencing mode:  73 Evan AC9TU

I have an old XLR microphone. Its body of it is in good shape. Could I get an electret microphone element and redo the workings of it?? -- '72

You are making sense. The ubitx is designed for an electret microphone. This is the easiest type to use. Traditional older microphones are dynamic, different principle and it requires added circuitry to function. Read the wiki article on electret. I am thinking everything in my shack is electret. Got a powered desk mike, ten tec. My favorite now is a PC headset, wired up adapters to use it with 2 of my rigs. I use a foot switch, music store type a LA amazon for PTT.?
I don't know if you can find an electret in that traditional form, maybe.?
With my v4 ubitx I still use an old HT speaker mike which does well in my case, no amplifier or speech processor yet.?
If you don't want to mod your ubitx stick with electret.?

Hey everyone, it's been a bit. Still stuck in bed and it is truly driving me crazy. Got a microphone question about choosing a microphone for the uBITX v6.? On my previous v6 I had a??that i modified for my uBITX v6. Now I do not remember where I got the instructions on modifying it.? This time round I would like to have a traditional type microphone and PTT switch. Has anyone come up with a mic that works with the uBITX?? What I mean by a traditional type microphone that looks like this:  I'm not sure of the different types like condensor and electrict just mainly something that will work with the uBITX v6? Right now I am adrift in an endless ocean of pain with some prescription medication so I'm not really sure if I am making any sense.? -- '72

Re: sBitx #sBitx PA MOD Plan
#sBitx
There are some of us who are incapable of handling the upgrade of
the early sBIT.? I am one of them.? Perhaps some of our more
capable users would, for a fee, handle this for us.? I know I
would be willing to pay shipping both ways to someone who would do
mine, plus something to reimburse him (or her) for the time spent.

I'm going to guess that there are a relatively small number of
owners at this point, of which some percentage will not attempt
this mod themself. As of the next build, all this becomes
academic, so this effort just needs to be adequate, not perfect.?

Hi Evan,
It does receive but it is off the frequency is slightly off.? I'll try a calibration since I did change the nano when I changed software.
If that doesn't get me anywhere I'll look at those voltages.??
Thanks, 73

Hi Spencer, Does the v6 receive as expected?? The most likely issue is that it is not calibrated correctly.? This is most likely the case if you changed the Nano when you installed the KD8CEC software.? The calibration data is stored in the EEPROM that, is not updated when you download the program, and stays with the Nano. The next most likely issue would be the mic preamp, Q6.? You can use the v4 voltage spreadsheet to check the transistors of proper dc bias voltages provided by VU2ZAP: /g/BITX20/files/VU2ZAP73 Evan AC9TU
