ubitx raduino issue/AKA the radio doesn't receive
My receiver hasn't worked since I got the kit.???I've put a frequency counter (Fluke 115 multimeter) on the raduino/ubitx connector, and clk0, clk1, and clk2 all have no signal. Display is lit and counts. The raduino is in the right position on the header (per mapping the ground pins on both boards), and the radio does not receive. Regulator 12VDC in, 5VDC out. Can anyone make a suggestion to get this radio up and running?? I'm pretty savvy when it comes to computers and electronics, but...? arduino is not currently in my skill set.
Thanks! |

Thanks for responding. If I really want more power, an external amplifier would be the way to go. Since that December post, FT8 has caught my attention, and more power would be overkill.

When I press the Raduino reset and the controller button the display briefly shows "Raduino 2.0" before returning back to VFO A: ?7.150:000

I desoldered all wires from the encoder.
The push putton funktions works from open circuit to 0 ohm when I push it. Connecting the yellow and red wire doesn't change a thing on the display. I disconnected all wires from the encoder and measured the following: ? The following measures to common ground on chassis: Yellow -0.03v Brown + 4.73v Red + 0.01v Black + 4.73v ? ? Measurements between controller wires: Yellow > Red + 0.04v Yellow > Brown + 4.73v Yellow > Black +4.73v ? Brown > Red 0.00V Brown > Black 0.00v |
Re: Should we adopt the KD8CEC firmware?
Dennis? W7DRW Perhaps I can provide a little information that may get you started.? The .hex file is generated by the compiler.? In the Arduino IDE on Linux it is stored in a temporary directory.? Windows and OS-X may be similar.? As Jack has said, you need to click on File>Preferences and check the box for verbose output during compiles. When you do a compile the location of the .hex file, and other related files, is shown near the end of the compile output at the bottom of the IDE window.? If using the Arduino IDE you will see something like this: /tmp/build4580944257211744891.tmp/BlinkWithoutDelay.cpp.o /tmp/build4580944257211744891.tmp/core.a -L/tmp/build4580944257211744891.tmp -lm /usr/share/arduino/hardware/tools/avr/bin/avr-objcopy -O ihex -j .eeprom --set-section-flags=.eeprom=alloc,load --no-change-warnings --change-section-lma .eeprom=0 /tmp/build4580944257211744891.tmp/BlinkWithoutDelay.cpp.elf /tmp/build4580944257211744891.tmp/BlinkWithoutDelay.cpp.eep /usr/share/arduino/hardware/tools/avr/bin/avr-objcopy -O ihex -R .eeprom /tmp/build4580944257211744891.tmp/BlinkWithoutDelay.cpp.elf /tmp/build4580944257211744891.tmp/BlinkWithoutDelay.cpp.hex Binary sketch size: 1,038 bytes (of a 30,720 byte maximum) I have highlighted the compiler output line that shows where to look for the .hex file. You do not need to do anything with this file if you want to use the Arduino IDE to install your new program on the Arduino.? Connect your Arduino to the PC via a USB cable. Go to Tools>Board and select the type of Arduino board that you are going to program.? Next go to Tools>Serial Port and click the check-box for your serial USB port (/dev/tty/USB0 in Linux and probably something similar in Windows).? Now go to File>Upload and your new .hex file will automatically be selected and installed in the attached Arduino.? There are many other things the IDE will do, such as installing a new bootloader, but new programmers do not need to be concerned with all that.? Arv?

Re: Variable IF
Attached is a schematic of the variable IF circuit. ?The RX and TX voltages are about 12V, so I used a resistor network to keep the applied voltage to about 1 to 9V because that is the usable range for these diodes.
The 4.7K resistors that feed the voltage to the VVC diodes could be 10 or 20 K, or what have you, as there is very little current needed. Tom W1EAT |
adding to base load software
Rod Davis
¿ªÔÆÌåÓýTim, I am a little confused by your post titled Re: [BITX20] Should we adopt the KD8CEC firmware? You mention a feature you may want to implement. To me, whether the 'base load' is hfsignals firmware, or KD8CEC firmware, the problem seems to be the same. You can add or delete features to/from either firmware. I quote your email: It's my opinion that we *need* a base load with a set of common functionality that experimenters can build on. The current software that Ashar provides seems to fit that bill. If someone wants to load other software then it is up to them to manage all the complexity. --end quote-- In your example, especially the second paragraph quoted above, it seems to me that either 'base load' would suffice. Am I missing something? Rod KM6SN |
Re: PA breaking into oscillation? (uBitx)
OK. Figured it out.?
Relays are fine. The culprit: I have?a PCB trace,?with the node/net L1, C200, C80 running parallel to my RF output trace (from relay KT1, pin 5) causing feedback. Doh. I should have realized this much sooner. Chased the rabbit down the hole, but I caught him! -Mike |
my take on ?BITX panels for EF01 enclosures
#ubitx
#3d_printing
I finally got around to designing and printing ?BITX panels for the EF01 enclosure.? I switched out the LCD for a white on black one.? I ended up recessing it in the panel to avoid the need for a bezel.? It looks much better without the flash washing it out.? I also used a different volume pot so I had more knob options.? I had to angle the shot of the back to deal with the glare so you'll have to believe me the heat sinks line up with the openings.? The fins are just proud of the back with room around them for air flow.? The top 3.5mm jack is TRRS for mic and ptt.? I do not have a keyer jack.? Over the antenna connector is a mini USB connector.? On the back of the panels are recesses for the connectors that were too short to make it through otherwise.? The front and back are both glossy enough to show fingerprints.

Basic CW capability using the PTT switch on the mike is very lightweight

and?I'd tend to include it on any uBitx build. ? ??/g/BITX20/message/44349 What firmware gets shipped by hfsignals is up to Farhan,? primary concern is that it be easy for new users to do basic stuff. Those of us that want to hack can probably figure out a way to ifdef a common codebase that suits most of us well enough. We'll see, if I already knew exactly how this was going to turn out it wouldn't be any fun. Jerry, KE7ER ?? On Mon, May 14, 2018 at 02:41 pm, Tim Gorman wrote:

Re: Should we adopt the KD8CEC firmware?
if it was carefully and intentionally engineered with design documentation that will open the door for experimentation then I am all for it..if it was hacked on the fly with no or poor documentation then I would prefer to write my own like the project was intended..I sense too many folks bought this as an appliance to be a cheap rig, not the experimental development platform it was intended to be. Dont adopt anything, develop your own solution.

When I first got uBitx and fired it up, I was fully disappointed with the poorness of its firmware. Just to mention the stock Split operation. I am sure more fellow users will agree with me. Frankly speaking, it is thanks to CEC software that I decided to keep uBITx and play with it. Memory Manager is a very useful tool, especially if you come to things like the S-meter calibration or the recovery of factory calibration that has been added in version 1.075 I do share some of the concerns of the published responses about the size and perhaps the too many features, but I am convinced about Dr. Lee's ingenuity and I am sure he can come up with a good start up version that can be helpful to beginners and? feature upgradeable. Also if I may suggest, please consider using an I2C LCD that leaves a certain number of ports free for further experimentation and use. The cost of a I2C adapter for the LCD is minimal and I am sure you can purchase the I2C ready LCD cheaper.? A 20 by 4? LCD would make uBITx more attractive marketing-wise. Konstantinos, SV1ONW |
Re: Should we adopt the KD8CEC firmware?
Think of it this way.
I want to add a Tune item to the menu. The item will send a CW signal and monitor an i2c peripheral for reverse power indication while the CW key is held down. Do I duplicate the CW transmit functionality in my code in case someone wants to use my code to add the Tune functionality to their program? If I don't do that then it won't work for someone who doesn't operate CW and has deleted the CW function from the software. And the code gets bloated from two different menu items duplicating the same functionality for those that do operate CW. Or do I wind up having to maintain two versions, one for software that has CW functionality and one for software that doesn't? It's my opinion that we *need* a base load with a set of common functionality that experimenters can build on. The current software that Ashar provides seems to fit that bill. If someone wants to load other software then it is up to them to manage all the complexity. tim ab0wr On Mon, 14 May 2018 16:38:39 +0000 (UTC) "Jack Purdum via Groups.Io" <jjpurdum@...> wrote: I think it could be done without too much confusion by using |
