Hi all? which method do I use to wire audio amp to agc board like in the picture or do I wire from audio board to agc?

My latest improvement effort is to make the knob dynamically change its step size, so when you're tuning fast, it goes fast, but when you're trying to get the exact right frequency, it will let you. There's a lot of subjectivity in this, so it's more of an art than a science (though there is some science to be had).
https://github.com/reedbn/ubitxv6/tree/knob-acceleration
Joel (N6ALT) - I'd appreciate it if you could take it for a spin, since you seem generally up for some adventure.
Mark/Smitty - I'd also appreciate your feedback, since it's building off of your work with the interrupts.
Andy_501 - I've dropped the increments on the settings menus (among others, the local oscillator cal), so you may be interested in trying it out for that reason. I've attached a hex, since I don't think you've had success compiling?

Hi there,
I don't have a v5, but from my reading of the posts in this group, a good number of people use the "KD8CEC" software, which you can find on github at , and has a corresponding blog post here:

Hi Paul,
I read a number of specs for similar looking panels and some said 3.3v, and some said 5v tolerant, so it might be that you got a 3.3v only?
What specific code did you try and run?

I know this is a super old thread, but does anyone know anything about fixing the split mode with KD8CEC firmware? Or am I not understanding something. When using Rig split mode in WSJT-X, VFO a becomes the same as VFO B after transmit.

There is an adjustment pot there, both ubitx and qcx, maybe most lcd units. Many of us were slow to figure this out.

Re: [BITxV6] BRICKED recovery help needed
Thanks for f/b Jerry,
that lag due to display update might well be something to
investigate as when CW is selected as mode the key down cause the
TX button to light then the RF appears at the output so clearly
that is a lag possibility. I would have to compare the sequence of
events using one of the iambic keyer inputs to see if the lag
exists using the raduino keyer TX control as opposed to the PTT on
the mic line.
It is hard to imagine a class of basic hams trying to study to
upgrade to advanced levels having to go through this much trouble
with a practical kit before they can focus on course theory for an
exam.
Step 2 I just manually adjusted? the BFO freq so that I had the
best sounding audio from the two time signal stations in the
headset but could not zero beat or adjust it for? a zero
difference point so no tone was audible over the received signal
tones.

Andy,
I'm not quite sure I understand your first and second bullet
points.
But then I'm not familiar with the firmware you are using.
So feel free to disregard these comments in they seem wrong.
1.
I am unable to set the ref FREQ to 10 000 ; the closest is
10500
A 500khz error at 10mhz is an awful a lot, that's 50000 ppm
You might use a shortwave receiver to verify that the Si5351
crystal reference oscillator
is operating within perhaps 400ppm of 25.0mhz, so within 10khz
Probably somewhat high, as the crystal loading capacitance on the
Raduino is too low.?
2. ... The zero beat adjustment
allows me to hear the signals and voice
components/announcements but continuously has approx a 500
Hz tone superimposed on the time signals which appears as
though it might be due to the freq setting from step 1.
not working as text instructions state it to be set.
You lost me.? Is it 500khz or 500hz?
At any rate, if the calibration step for the 875mhz vco advances
in 875hz steps (so 1ppm), you should be able to get it within
10hz.
The operating frequency is always a ratio of the 875mhz vco, and
thus any error in the operating frequency is that same ratio
of any error in the 875mhz vco.
the
lag between key down and RF output is serious problem?
Got to be a firmware issue, perhaps due in part to the slow
display if they are trying to update the display when the key goes
down.
Not everybody here uses CW much, including those writing the
firmware.
The uBitx is primarily an SSB rig, but there has been firmware
that works well enough on CW.

Hi Reed,

I managed to get the test menu to work also somewhat
sluggishly.
1. I am unable to
set the ref FREQ to 10 000 ; the closest is 10500
2. The zero beat
adjustment adjusts above and below but does not produce
a zero beat state. The receiver works and I am able to
hear WWV on? 2.5 MHz and CHU Canada on 3.330 MHz The
zero beat adjustment allows me to hear the signals and

3. I am able to
select Hand Key setting and in CW mode it outputs the
full 10 Watts on 80 M band on key down; however if I key
a test transmission at about 10-12 wpm with the hand key
the lag between key down and RF output is serious
problem (no setting of key delay helps improve). It is
so bad I would not be able to use it for CW operation. I
plug the hand key into the Mic jack and have the key
control the PTT; in CW mode it generates CW sidetone
signal but hand key does not work when plugged into the
J4 Morse Jack at all.
4. Changing modes
using the color display buttons and a stylus works but
it also exhibits serious delays and even sometimes
requires selecting the new band a second or third time
to finally get it to change. It is almost as if the
morse code hand keying and TFT screen servicing routines
get hung up in an idle code loop delay of some sort that
makes the overall operation seem sluggish or seriously
lagged or unresponsive/insensitive.
But on the plus side The BRICKED white screen appears to have
been cleared up; The only other possibility is that the
TFT/nano daughterboard pair has a problem that is creating the
sluggish performance; and HFSignals promised replacement has
not been sent to me and thus I am unable to compare it with a
supposed new one. They promised on two separate emails to send
me a replacement however have not so far lived up to that
promise.
Any suggestions now Reed?

My unit came with only one jack with the 2.2K resistor and a 10 K
resistor connected to the Tip and Ring with the J4 sleeve ground.
I don't have an extra 2nd jack installed in mine connected with
Tip Sleeve providing a direct ground to the keyer input pin. The
only description I had wrt straight key was to use the Mic
connection and connect the hand key to the PTT line which is
different point than the keyer line and might definitely be a
source of aggravation lag from key down to RF output timing.

Here¡¯s a picture of the stock Baofeng microphone I use on my v5 before I connected it.?
I removed the capacitor (C2) and resistor (R1) between the (positive) electret microphone lead and ground - these are not needed (or wanted). Then I connected red for mic, yellow for PTT, and blue for ground. Green has no connection.
Also, these wires are extremely fragile - if you¡¯re not having any voice modulation, you might check continuity from the solder point of the red wire and the tip of the plug.?

Is the included mic a stock Baofeng mic or has it been modified for the ubitx?

#ubitx #v6 Internal Microphone wiring on provided hand mic
#v6
#ubitx
Can someone tell me how their hand mic is wired, the one provided
with the uBitX v6?? It looks like the speaker is in series with the
ground wire on mine, and I'm trying to figure out if that's
expected.
There's a board inside the hand mic.? It has terminals for Mic, PTT,
GND, and Spk.? The mic connector on the uBitX doesn't have speaker
signals, so we care about the Mic, PTT and GND.? The 3.5mm TRS mic
connector should be wired as:
- Tip: Mic, red wire
- Ring: PTT, black wire
- Sleeve: GND, white wire
In my speaker mic, the GND terminal is connected to a green wire,
which is cut-off inside the 3.5mm connector, it doesn't go
anywhere.? Instead, the white wire is connected to the Spk
terminal.? The other side of the speaker is connected to ground.
For PTT, this just effectively adds about 8 to 16 ohms to the ground
side, but against the 10k-ish pull-up on the other side, its still
plenty low to register.? So PTT works fine.
But this also puts 8 to 16 ohms in series with the mic signal.?
Looking at the mic circuit in the uBitX schematic, that shouldn't
matter TOO much.? The rest of the circuit is 4.7k, 2.2k, and 10k.?
So 16 ohms should be noise floor compared to those impedances.
Having said that, my uBitX doesn't want to put out power on SSB.? I
key up, but my meter doesn't register any power.? If I key up CW, it
registers power just fine.? But not on SSB.? I don't THINK this is
the cause, but I'm putting the question out to see if anyone else is
having a similar problem, or whether their mic is similarly wired.
Thanks!
