If you would like to donate a uBitx to the creation of a manual, someone here may do it.? While you cant go to the bank and cash in 80 hours for money, time is not free.? I¡¯m surprised after you have written 11 books, how much you downplay the time and energy required to document something as well as you would like it.

Re: Shaking my head in disbelief....
Arv, when in doubt, use Github! It works, but doesn't fill the screen. I do have the KD 8 CEC software though.
I'm done modding for the moment...? ?I found ubitx_35E7.tft...now to go play awhile...

Hi Bill, same here; I used ubitx_35E7.tft...it says 3.5 but doesn't fill out the display....

Hi Dan,
I loaded UBITXV5_CEC_V1.122_16P.hex into my v5 and it works
great.
Hope you have the same results.
But I am still trying to get my 3.2 NX display to work right - it
leaves about 1/2 inch on the right side.
but for now I just use the 16 x 2

Hi Dan, if you look at top line of where you downloaded those files it should say filename info. Click it and it will tell you which one is for the stock display, but you may have read each description.?

Read carefully! I did not say LInux does not use device drivers, I said LInux does not use device drivers "the way Windows and Macs do"! All the device drivers I need for Ubuntu are already included in the distro, and and they are remarkably non-fussy about this chip or that chip. Counterfeit Prolific chips work just fine with /dev/tty!

Take your DVM to see if you have continuity from the center pin on the RF connector all the way back to L4.? you can do this with dc power on, such that a relay is connected.? also check to make sure you don't have a short circuit at the antenna connector.? eliminate the easy first.?
Have you checked CW transmit?? Do you have an audio sidetone and RF output??
I would check more than one band in case you knocked something loose in the low pass filter section.?

Re: Reverse Polarity Protection.
Tastes vary.
A series diode into P1 pin 1 plus a fuse at the power supply seems plenty elegant.
If worried about overvoltage, use an LM2940T-12 instead.
Not being a mechanical engineer, relays not so much.
But if building a 1kW linear with high currents involved, I'd consider the relay.

Someone else will have to help you with the Nextion software.? All my
systems use conventional 2-line and 4-line LCD displays.? There are plenty
of Nextion users hanging out here so someone should provide an answer
to your question.

Hi Arv.. thanks for the info, I also have found the right programming cable in the dark depths of my junk box.? I found and uploaded? v5 firmware successfully from ian's site, but I cant find the Nextion tft for my NX4832K035_011.? Can anyone help me. I'm confused;?
I thought they were contain within the software and the different display was contained in the software but I guess I'm wrong

Re: My uBitx Easy-Digi interface for under $20
Dear OM,
I am interested for buying it.? Please inform in details.
73s. Balsun, VU2UYC.? From KERALA STATE, INDIA.
If anyone is interested, I have put together a google doc that shows part sources I used for my PC to uBitx "Easy Digi" interface, and the document includes a few tips.? It works and looks good, and I made my first PSK31 using fldigi from here in Ohio to New Mexico last Sunday night.? Works great, all for under $20, including cables.

Re: Reverse Polarity Protection.
I far prefer the approach below as you are not crow-baring voltages, blowing fuses, shorting diodes, and letting smoke escape: ? ?

Subject: Re: [BITX20] Reverse Polarity Protection. ? The PFET reverse polarity protection is not a bad choice if you need the minimum possible voltage drop.
But it's easy to goof up.? Some schematics for this on the web show the PFET
placed backwards, and thus offering zero protection from reverse polarity.
At power up, the intrinsic reverse diode conducts from drain to source, till the source is Vgs above the gate.
At that point, what is hopefully an enhancement mode PFET starts to conduct, reducing the voltage drop
between drain to source from a diode drop to that incurred by the current through Rds-on.
For a uBitx, I'd recommend instead a diode (most anything capable of dealing with 500ma)
in series with the main 12v into the board at P1 pin 1 (which also protects the Raduino).
We can afford a slight voltage drop there, and this is much easier to understand.
The 12v into PA-PWR on P1 pin 2 for the IRF510's can be a direct connection, since a reverse voltage
on PA-PWR will cause the IRF510's to conduct through their intrinsic reverse diode.
If there is no fuse then some easily repaired board traces (and/or L8,, L9) will blow,
but not your IRF510's.? Diode protection here is ok if you insist, but you will need
a fairly hefty diode, and the diode drop will reduce transmit power by a bit.
A 3 Amp fuse between the power supply and uBitx is highly recommended.
Without reverse protection into the main board, the Raduino can fry because
the ancient LM7805 on the Raduino does not block a negative voltage.
There are newer regulators such as the LM2940 that do.
Replacing the protection diode recommended above with an LM2940T-12,
gives protection for reverse battery voltage, it will also protect the rig
from excessive battery voltage.? (PA-PWR should not go through an LM2940T,
as that will draw too much current.)?
Jerry, KE7ER
But many people who use don't understand how it works, and often circuits found on the web show the FET backwards.
for this scheme show the FET in backwards.

Update after using the uBitx for about 2 weeks:
Listening to SSB voice was possible for strong signals after setting IF shift to 3000
(CEC firmware)
1) interference from the KGO AM station is now gone
2) it is possible to listening to strong SSB signals (I use the
to get an idea of where a strong signal can be found and then tune the uBitx to that
frequenc. S9+ SSB signals at Half Moon Bay can generally be heard by the
uBitx in Silicon Valley).
