I never got any resistors in my bag of goodies for the v6 I received. Fortunately I have no plans to use CW. I've long ago forgotten most of the code since passing my General way back when... ;)

ubitxv6 mic not working fine #ubitxv6

eb2elu@...
 

Hi,
I was testing output power and I noticed that there was some issues with my microphone.

I only could get output power (10watts un 40 meters) when I blow directly to the hole of the baofeng microphone. If I Talk or I screamed a little I didn't notice a little bit movement in my  power meter (1 watt or less)

I have read that un bitx20, bias voltage un electrect microphone should be 10 volts.

What is bias voltage for mic un ubitxv6?

I measured It and I only got 5 volts un baofeng microphone...

Is this ok?

Any ideas about what is happenning yo my microphone?

Yes!!
I just watched It yesterday and I think I finally calibrated It.
Thanks

Re: CW key cable for uBITX V6

yes indeed its unusual but pins are scarce on the nano. if you only employ one connector you can set it up for straight key or paddle.  some folk set up for straight key (if they use one or an external keyer) and build an adaptor put plug between their paddle and the key jack.  its not as simple as telling the menu key or paddle - although you need to do that also. 

info around if you search for paddle with ubitx

external amplifier keying.

I would like to be able to key an external amplifier. I wonder if I could use the"XMIT" signal which appears to be positive going to bias a switching transistor to activate a relay.  Suggestions are greatly appreciated.

Thanks for the quick reply, Jack.
Is  0.12A just the 2.8" LCD current or the total nominal receive current?
I would like to know the total RX current of a V6 with the standard 2.8" display.

It varies with the size of the display and its resolution. The JackAl display (5", 800x480) draws about 0.8A. I am currently using a 2.8" touch screen display and it draws about 0.12A

Re: new V6 owner with a few basic questions on wiring and software #v6

Hi Tim,

I use the "AVRISP mkII" programmer setting, and the "ATmega 328 (old bootloader)" processor option.

You shouldn't need to burn a bootloader.

Re: can I bypass the CP2102 chip on the NANO with an FTDI based serial adapter? #arduino #cp2102 #ftdi #nano

K7UL@...
 

Hi guys, I know I am replying to a year and half old post, but I ran in to a problem with my V6 and win10.  The driver for the cp210x was set to use COM4 and the driver the CH340 also was set to take COM4.  I had to go into device manager to find out why I could not upload to the bitx.  It did work yesterday somehow.  Moving the cp210x to a free com port fixed the problem.  The CH340 driver for the nano works again with the arduino IDE.

73, Andy.

Re: RX #V6 quits working when ant coax braid is connected #v6

 I lost a few items to line surge and spikes due to nearby lightning strike over ten years ago.
 PC lost power supply, and motherboard, but CPU and RAM plus a few cards survived. Also a few other items were lost.
 Never know.
 I knew a person who had a TV antenna hit, lightning came down the ground wire and through a solid wall into house wiring, with items on that run being damaged.
 
 Also, back in the early 70's, a lot of TV sets needed diodes replaced due to line surges.
 Never know what lightning will do.

Re: uBitx v6 jacks on purchased enclosure

Thank you very much. This photo of the board with the jacks labeled is EXACTLY what I am looking for!  Now, my only further question concerns the J3 Speaker jack.  Is this jack for headphones?

I really appreciate your quick turn around on this.
Thank you.

Re: V5 not receiving local am stations

Wayne Leake
 

 A number of antenna tuners have the option of bypassing so the antenna is basically bypassed.
 My autotuner, as well as an older manual tuner have the option.
  
 And I am going to have to replace coax due to a fire in the shed where they pass through.

Solved!
Thanks to all who helped.
It turned out to be my manual antenna tuner not being able to tune in MW. I connected my antenna straight in to my ubitx and all those MW broadcast stations came to life.
Someone on this forum did mention my antenna, I should of listened earlier.

Re: Size and type of USB program cable

N0YWB
 

Most Arduino Nano boards use a USB mini receptacle, so that is the receptacle on the uBITx v6 chassis. note: Auduino Nanos are now available with micro USB and USB C connectors.
 
You will need a USB A to mini USB adapter cable, available at most derpartment stores.
Example: https://www.ebay.com/itm/372572584649
 
Mini USB is obsolete. It was quickly superceded by the slimmer micro USB,
Micro USB is what you see on the majority of Android phones and notebook computers today.
 
Micro USB has recently been superceded by the USB C connector. 
USB C has twice as many contacts and an oval shell,
so it does not matter which way is up and is less prone to damage than the micro USB.
USB C is also designed to handle 20 Amperes at 5 Volts.
New devices will use USB C, like the Raspberry Pi 4 and nanoVNA.
Micro USB to Type C adapters are inexpensive 
Example: https://www.ebay.com/itm/352721046229
 
A micro USB connector has a fifth contact, used to determine host or device role.
A USB "On the Go" (OTG) adapter can turn a USB device to a USB host
Example: https://www.ebay.com/itm/312633558827
 
Note that the Teensy 4.0 micro upgrade for the uBITx v6 has a micro USB connector. 
I recently bought a digi card for my uBITX v6 that has a USB B chassis receptacle.
Example: https://www.ebay.com/itm/391913912457
 
To support experimenting, buy a set of USB connector adapters. 
 

Re: winlink error on TX #v4 #cat #digital

Don - KM4UDX
 

Gary, Andy, + ....given droves of uBITX WSJTX  users enjoy reliable CAT PTT  for  FT8 all over the world, it is clear uBITX PTT USB is reliable.  Ditto for all the 24/7 uBITX WSPR mode obsessive  fanatics (why are you looking at me?). Essentially, all our digital mode uBITX operations are possible BECAUSE of rock solid uBITX CEC USB PTT. Ditto for all you Fldigi fans out there with your chatty PSK31, Olivia, Contestia, etc digital modes: you all took USB PTT to the bank. 

Not so much Winlink. The going in assumption was that we've screwed up some winlink/winmore config setting. I have lots of (recurring) documented user error supporting the notion that the operator (me) screwed something up, as normal. Trust me this is the safe bet. Hahahha. 

But after lots of trial and error and community engagement, the problem may be some subtle or peculiar winlink/winmor USB PTT implementation. 

Who knows.  I continue to noodle around the winlink settings. Stumbling over settings like a drunken sailor is more productive than you'd think.  Hahah. 

If you don't mind feeling like a prisoner in a cruel Turkish jail for hash smuggling, you can grind through every possible setting permutation. Untill you randomly find the right combination.  This process works wonders when I have to hack my own passwords. Hahaha.

If someone can figure out the secret uBITX / winlink handshake, there will be a few very appreciative folks out here. Well me anyway. Hahah.

Re: new V6 owner with a few basic questions on wiring and software #v6

Thanks,

I tried to upload the new firmware but following Ashhar's video does not seem to work for the board supplied in the unit.

I did successfully upload the sketch to another Arduino I had but that one has the male pins on the opposite side of the board and has female on the side that would plug onto the Raduino so I can't use it...

Following his video, I see in his tools drop down "Programmer: Arduino Gemma", yet I do not have that option. No other option works, and I always get an error that it cannot communicate with Programmer Ar--something or other.  I am not super familiar with all the terms, but it seems the Arduino IDE cannot communicate with the board MAYBE because it needs a Bootloader installed??? this from searching their help section. I hate to burn a bootloader to the stock unit without knowing if it will work, or erase the program or what. Maybe he burned these with a bootloader not included or compatible with the Arduino IDE?

anyhow, I did get the unit fired up this morning but have a screech coming from the speaker until you turn the volume at least half way up then it goes away. Unfortunately, even at full volume it is barely audible unless you put your ear within inches of the speaker.

I will try a different power supply and speaker and see how it goes.

Anyone else have problems using the IDE to communicate with the board? (I tried 6 different cables, don't think it's that as it does ID the board, port works, etc.)

Thanks again!!
