we are trying to do as many mods on a bitx40 we can but I need listings for all the mods

Re: WSPR built-in software plans? #ubitx

The arduino nano board is very limited and memory is about maxed out. I’m working on porting the firmware to Teensy which has much greater capability. I also plan on incorporating WEPR mode using the JTencode library. Teensy 3.5 also has a sd memory card slot, so other features could be implemented the work in progress is at github.com / mosteveo / uBitx_Teensy. 

Dont install it on yout nano or bother installing it on a spare Teensy yet it is still a work in progress in the very early stages.

Re: uBITX Low Power Output

WA9GQT@...
 

More information: I followed the PA bias adjustment per HF Signals. Lower than specifications!
Receive current = 150 mA
PTT pushed with both bias presets fully clockwise = 380 mA.  Should be higher ( 470 - 500 mA )
Adjusted each bias preset 100 mA higher = 580 mA. Should be higher ( 670 - 700 mA )
What about adjusting RV1?
I did make another contact on 80 meter CW. Got a 569 from Bob in Richmond, IN with only 3.5 watts.
Any further assistance would be appreciated.

The W0EB/W2CTX/N5IB “RadI2Cino” (pronounced Rad ee too SEE no) is still available. #ubitx

Jim Sheldon
 

The RadI2Cino is an almost exact drop-in replacement for the original uBITX Raduino card.  It does require the addition of one push button switch and it will also benefit if a separate “hand key” jack is added as well. 

The RadI2Cino was not designed to operate with the original BITX40 or earlier series BITX kits. 

You can order bare boards, kits of parts (including the board but less the Nano and display components) or if you really don’t think you can build it yourself, fully assembled and tested RadI2Cino’s (less display and display controller) are also available.  See the following options:

1.  Bare Board (you supply the parts & you build it).  $10.00, US shipping included. .  International, US $15.00 shipped.

2.  Complete Kit of Parts (except the Arduino NANO, LCD display, display I2C controller, extra push button and hand key jack). We supply the parts, you build it.  $30.00, US shipping included.   International, $45.00 US shipped.  All customs duties and VAT will be the responsibility of the purchaser.

3.  Completely assembled and tested RadI2Cino Including a pre-programmed NANO but without the display and I2C display controller. Special Order Only (will require up to a 1 week lead time between receipt of payment and shipment). $75.00, shipping included in the U.S.  No international orders will be accepted for assembled and tested boards at this time.

All orders will receive the complete, very comprehensive assembly manual which includes a full bill of materials, full board layout diagrams and full schematics in PDF form via email. Purchasers will also receive (via email) the latest, stable release of the software specially written by W2CTX specifically for the card.

Parts suppliers are Digi-Key, Mouser and Tayda. Their part numbers are contained in the Bill Of Materials.

Reverse Beacon Network

Rob Snow
 

If you are like me and not having a lot of luck with SSB QSO due to the recent crappy conditions or want to debug your apparent low voice output the Reverse Beacon Network can come to the rescue.  RBN listens for CW CQ's and reports who heard them.  For the uBITX you can add in Ians (KD8CEC) wonderful firmware and even without a key you can send a message via the Automatic Key Memory function and see both who can hear you and what your uBITX output actually is under ideal conditions.

What I did:

  1. Installed Ian's (KD8CEC) firmware (1.04) http://www.hamskey.com/
  2. Downloaded the Ian's Memory Manager http://www.hamskey.com/
  3. Edited the Auto CW memory to "TEST DE <YOURCALLSIGN> TEST DE <YOURCALLSIGN> #" (the # is the prosign for AR)
  4. If the TX/RX delay isn't high enough you will flop back and forth with annoying clicks when you aren't interactive anyways, I set mine to 1000ms and 400ms.
  5. Tuned to the CW/Data area of a band and set to either CWL or CWU
  6. Select Auto CW
  7. Push the PTT to send it
  8. Look yourself up on RBN http://www.reversebeacon.net/

What I discovered is interesting, I'm being heard and I'm maxing out at about 1.2a @ 12.0v via CW compared to my 800ma @ 12v for voice when I'm eating the mic.

I think that's telling me that part of my issue, besides conditions, is in the audio input side of the world.  I've ordered an assortment of 1206 SMD resistors and a package of replacement electret mics (both from Amazon) to see if I can fix it that way...mic element first.

Anyways, I thought I'd pass along the tip for those of you wanting to see if it actually works and someone can hear you!

Re: uBITX Low Power Output

KE0GYC
 

I've got the same issue - low power, and low current consumption with PA bias at zero.

Re: uBITX Low Power Output

Rob Snow
 

To chime in, I show the same currents on my uBITX (320/3).  I see 380ma  PTT, Bias full clockwise.  160ma on, no PTT and volume very low. I set the biases to end up at 600 (110 each).  When I watch the current from the power supply (12.0v) I get ~800ma when eating the mic.  When I switch to CW (using Ian's firmware and CW auto keyer to hit RBN for testing) I see ~1.2a @ 12.0v, so consuming 14w.

Hi Nik, 

would it be too much to ask for
1) a high stability TCXO oscillator for the Si5351, 500 parts per billion or better 
2) an I2C IO expander chip for the LCD display
3) PC board pads for a RED/GREEN/BLUE backlight display (it's an 18 pin SIP)
4) PWM driver for display LEDS (optional add on)
5) can you make the PC board outline match the LCD display exactly, along with the mounting holes. 

notable mention QRP LABS has some nice Si5351 kits https://www.qrp-labs.com/synth.html if you want to avoid soldering SMT parts.

Arduino starter kit arrived

David Wilcox
 

After seeing someone post about this Elegoo Basic Starter Kit (Mega 2560 Project) for $30.00 I bit and ordered one last week.  It came today and arrived in a cute heavy duty plastic box similar to the ones Farhans radio kits come in.  It has what I call fair to good Chinese quality appearing parts, a solderless breadboard and Elegoo's own Arduino board along with a small data disk.  I printed out the manual and it appears to be written in good understandable English with a slew of high quality photographs and drawings.

I am a newbie to these Arduinos so as I build my Bitx40 I will go through the 17 lessons turning lights on and off, making a fan run, beeping and chirping and whatever else this little thingy will do.  Hopefully at the end I will have a working Bitx40 and understand a little about what all you guys are talking about in this group.  I have been faithfully reading all the posts and copying the ones that might help me not make mistakes.

So it looks like my $30.00 was well spent.  This Elegoo company has a lot of neat stuff for the robotic kids and the little chips that make them work.

two-tone test on ubitx

Tim Gorman
 

Attached is a screen save from my spectrum analyzer for a two-one test
of my new ubitx.

The tones were driving the finals to about 10watts output (not quite,
but close). I had a 30db external pad and a 10db internal pad in the
SA.

The carrier was only down about 20db (marker 1). That's not as good as
I expected. I'll have to look at that and see what can be done to
improve it.

The 3rd order IMD (marker 4) was down about 34.5db which is adequate.

The heat sinks get *hot* while running a key down measurement like
this. If you are going to use the rig for a digital mode it probably
needs to be set for about half-power out of the rig. That or a
significant increase in heat-sink capability should be installed.

This tuner is not automatic but it does provide a good load to the

While I agree somewhat I am not in favor of an automatic antenna
tuner because if your wire (especially with a new antenna or
experimental antennas) and supporting arrangement leave you without a
close match the time it takes the automatic tuner to get a match it
may be too long out of tune and blow your finals. With a manual
tuner you can key down for a short time while tuning, let it rest a
few seconds, try again getting closer, and finally get your match.
Keeps the finals cool and prevents the smoke from being released.

I have a Z 11 Pro and while I have not blown any finals I am very
touchy with my antennas and check them with an analyzer before using
it, just to make sure I am close.

I prefer a small Z match like the Emtec, 4SQRP tuner, GQRP tuner,
etc. At the home shack I use an MFJ 300 watt roller inductor tuner.
The reason I like manual tuners at home is I can look at the numbers
on the dials and if they are different from what I usually see I look
for antenna trouble, ie., antenna down, ice coated, wrong antenna, a
short somewhere. With the automatic tuner it just tunes and you
don't know if its the antenna or the tuner that is making your xmtr
happy. And even at 5 watts or less we can fry a 510.

I admit I am a nerd and like to tinker versus those who like to "just
get on the air and make a contact". My preference. This is a
wonderful hobby and we all are different.

Hello,
mine does the same thing :-)
I powered the PA with a tension of 16V and I get now 10W on 7 MHz, 7W on 14 MHz etc.
Be careful if you test, you have to apply 16V on the brown wire of the connector and 12V on the red wire. Don't brake the toy :-)

Re: Raduino Replacemnt, COMING SOON!

The Oven based Si5351a kit from QRP-Labs should be adaptable to your existing
Raduino board.  It will require a small amount of PCB surgery but probably not
beyond the ability of most ham radio operators.  That might be less expensive than
a major re-design of the Raduino board and software.

There are TWI (two-wire-interface) or I2C LCD displays and adapters for converting
parallel port LCD displays to I2C available from several vendors in the US, and on
Ebay.  Using one of these displays would free up some ports on the Arduino board
as well.  Of course you will need to do a few modifications to the Raduino software
but that too should be fairly easy because there are libraries available with the
necessary routines for I2C interface.

While editing the software it should be easy to add a menu item and PWM output
routines for the backlight.  This will probably require a transistor or MOSFET
buffer to handle the backlight current.  Tests may be necessary to insure that
this does not add to receiver background noise.

Adding drivers for selecting Red, Green, or Blue backlight could be more of a
problem unless you are willing to make a new PCB layout and boards for a new
Raduino PCB.   Rather than trying to stay with 1602 style 2-line displays this might
be time to change the display scheme so that it uses a multi-color TFT display.
Some of these have enough graphics capability to do simple SNA (Scalar Network
Analysis) functions to further enhance the capability of your new Raduino board
and related software.

I ordered my uBitX on Jan 11, 2018 and it was shipped on March 9, 2018 arriving in south central Washington State, USA on March 12, 2018.

I have completed the mechanical work.  Now to get to the wiring.  The case I used was a box I had bought for some project over a decade ago and never got around to using.  I ordered a speaker grill from Amazon for about US$2.50.  I decided to use a pot with switch from my junk box in order to have a standard size shaft.  It came out of an old Radio Shack CB set.  It is an A10K so should be fine.  The knobs are from an old Henry Tempo One (Yaesu FT-200).  The speaker is from my junk box as is the 12vdc fan.

Attached are some photos of the project so far.  It has the wx 2822 so I went ahead and ordered a couple along with a socket just in case.

To: "WSJT software development" <wsjt-devel@...>
Cc:

The WSJT Development Group is pleased to announce a third Release Candidate of WSJT-X Version 1.9.0.  A second release candidate, v1.9.0-rc2, has been tested in the field over the past three weeks, including a public test of FT8 DXpedition Mode conducted on March 6-7.

A General Availability (GA) release of v1.9.0 will be announced at a suitable time, probably in the near future.  After that time you should stop using any -rc# release candidate.

Here’s a short list of features and capabilities added to WSJT-X since Version 1.9.0-rc2:

1. Corrected a number of flaws in Fox behavior, FT8 DXpedition Mode

2. Allow Hounds to use compound callsigns in FT8 DXpedition Mode

3. Write debugging information to FoxQSO.txt

4. Fix the "Blue Decode Button" bug

5. Allow partial processing of incoming UDP Reply messages so that
   non-CQ/QRZ decodes can be processed. The processing is the same as
   double-clicking the same decoded message within WSJT-X except that
   "Enable Tx" will not be enabled.

6. Send DX grid locator to wsjt_status.txt, for use by applications like
   PstRotatorAZ

7. Correct the display of DXCC status of KG4 calls

8. Updated copy of cty.dat

9. Updates to documentation

10. Updated Hamlib functionality including changes to the Yaesu FT-817
   back end that allows the uBITx kit transceiver to be CAT controlled
   by WSJT-X.

10. Other minor bug fixes


###############################################################################
              *Second Public Test of FT8 DXpedition Mode*
              -------------------------------------------

If you decide to install v1.9.0-rc3, please help us by participating in the second public test of FT8 DXpedition Mode scheduled for April 7. Once again, the goal is to simulate a rare-DXpedition pileup by having many stations ("Hounds") calling and trying to work a designated pseudo-DXpedition station ("Fox").  Note that everyone participating in the test *MUST* use WSJT-X v1.9.0-rc3.  In addition, you must read, understand, and carefully follow the instructions posted here:
http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf

Please be sure to read this document carefully, again.  A few of its details are different from the previous version.

If you have legitimate access to more than one callsign (spouse, club call, or whatever) please feel free to call and work the Fox more than once. We want the test pileup to be as deep as possible.

The scheduled test will take place as follows:

Date    UTC   Frequency     Fox callsign  Operator
---------------------------------------------------
April 7  1400   14.105 MHz    W1/KH7Z       N1DG
April 7  1500   14.105        W7/KH7Z       AA7A

If last-minute instructions are necessary they will be announced on the "Ping Jockey Relief" chat page:
