Re: #bitx20 #bitx20

 

I got one for a BITX40 from HF Signals last year and I believe they are still listed.? I was told to let them know it was for a BITX40.

I just looked and they are listed at $45.

Re: New ubitx v6 no tx

Cameron,

As Stephen suggests, the first step is ensuring that the transmitter amplifier is working before looking at the SSB sections.? That is done on the v6 by selecting CW as the mode and using the mic PTT switch to key the uBitx.

If CW does generate over 8watts, then see if you can get any output on the power meter by whistling into the mic.

You can also monitor the current draw of the uBitx to see if the amp is drawing current.? On CW, it can hit 2amps.

Let us know what you find.

Re: New ubitx v6 no tx

 

If you get power output when pressing the PTT in the CW mode, more than likely it is the microphone. Based on my own personal experience, I highly recommend purchasing a CB microphone with a built-in preamp powered by an internal 9-volt battery.

Re: Correct resistors for v3 for CW paddles?

 

Seems like I am getting an extra dah and have had for years so I am trying to figure it out...

Re: New ubitx v6 no tx

 

Maybe try to set it to CW mode and check for carrier power when keying the mic.
Re: New ubitx v6 no tx

 

did you have transmit power before you made the modification?? If so, how much, what mode, which bands?

Hello anyone know where I can get a couple of raduinos from in the UK
I got the Bitx40 and the v3 uBitx

Correct resistors for v3 for CW paddles?

 

Folks, I am looking backwards in time on the site, and I am trying to find the correct resistor combination for the two or three resistors for correct paddle function.
I am also looking for the board layout for a v3
Anyone have this data handy?

Thank you David, it sounds like you have a pretty great setup

Re: Nextion Display Install #nextion #v6

 

The KD8CEC software is here:


You will also need the Nextion files.? Those depend on the Nextion size and model (basic or enhanced). There are tft and hmi files in the Files folder of Groups.io.? The tft files are the compiled version of the hmi files.?

Re: uBITX v6 upgrades #nextion

 

The case that I am using has almost the same front-to-back dimensions as the stock uBITX v6 case from HF Signals. What is throwing me off, is the BNC connector on the uBITX board sticks out on the larger case just as it does stock uBITX case.?
Here are some pics showing what is going on.
The pic below shows the BNC connector in the original case.

This next pic is the position of the BNC connector in the new case.

I hope this helps

Could you integrate inside the software a ¡°menu¡± allowing the OM to choose to TX only inside Ham Bands, of which the edges could be set by the OM according to his country regulations or TX also outside the Ham Bands, for exemple to use it with a transverter? I guess this would be a nice addition to this project and would make of it a ¡°universal¡± XCVR.

Nextion Display Install #nextion #v6

 

I'm reinstalling a Nextion display. I do not remember what all I need besides the hardware. I have the uBITX Memory Manager and X Loader. I can't recall where to get the latest firmware to be able to run the Nextion display. I will be grateful for any help.

Re: uBITX v6 upgrades #nextion

 

Aaron,
If you are installing into a bigger cabinet like what is shown, just get a 90 degree bnc connector to connect to ubitx and run coax to tuner with another bnc fitting. That way you are keeping the ubitx stock and wont have to re-install ubitx bnc on board if you ever chnge everything out

I installed mine in a bigger case also but only later. I installed a ldg100 tuner into mine. I took the tuner out of the case and made brackets to hold it in place where the speaker sat. i installed a jack for an external speaker. I have several i change out depending on the modes i use. the tuner sits just under the lid where the speaker sat. also i used coax after removing the bnc connector ,to run ubitx to tuner. I connect to the tuner with a bnc connector same as outupt, and then the coax solders to a connector to the case for outside antenna . I soldered a momentary push button in parallel to the existing one on the tuner and carried the wires to the front of the radio case. Led ,i removed and mounted it to front of case also. so when you push the button,it acts just like when in the case. for power, i split the incoming power at the power jack and ran a connector to the tuner.

Basically that all there is to it.
Im in the process getting a larger cabinet for everything since im building a 50 watt amp that will sit inside the cabinet with the ubitx.

hope this helps.,

Hey guys, it's been awhile

I'm doing a couple of upgrades to my v6 so I'm gonna have questions. I am going with a much larger case in order to fit a 3.5" Nextion Display

Using a larger case gives me even more room inside. I have an N7DDC ATU-100 with the QRP mods to it. I plan on putting it in the case. I now have my first question.
Do I need to remove the BNC connector from the uBITX main board and run a piece of coax from the uBITX board to the ATU board and another from the ATU board to the new BNC connector on the back panel?

Re: Raduino32 ESP32 flashing issues #raduino32

 

Not sure what I did differently, but after flashing with the flash download tool and restarting the Ubitx a few times, it works.

I still need to solder the 100nf capacitor between the +3.3v track and GND.

Hi Caleb,

The download seems to be correct. This is the result on my uBitx.



After the download, there is no automatic reset: you must turn the device off and on again.

If after doing this it still doesn't work properly, I'm wondering if there is something wrong with the hardware. It would be very helpful if you could connect a USB-Serial adapter to port 2 and read the output during boot, as a lot of information is sent out this port.

I will be available all week if you need me.
