Re: Cheap Bezels
William Londree
Several years ago when I was building Classical Guitars, I purchased a package of 12 Wood Laminating strips from Woodcraft. They are 1/8 inch thick and 7/8 inch wide by 24 inches long. There are several different colors so I plan to use a black one and rip it into 1/8 inch wide square strips. Similar to Arv's idea, I can construct a home made Bezel. Corners can be mitered using an Xacto Razor saw.
This idea is some what more expensive than Arv's idea but I have the stuff on hand (bought it on a whim and never got around to using it) and finally see a use for it. My uBITX will go into an Excellway plastic case and I will do a photo on it later. Bill W6SDI |

Adjust the Contrast (pot on the back of the Raduino).? Took me a while to figure this out.? Its set default at max and that is the problem.

I would guess that one of the upcoming new firmware versions with cat support would allow for cat ptt. That has always been my preferred option with other rigs (ie ?ft-817)
The opportunity to play with both hardware and software mods like this is just amazing. ? |
Sharing codes and method for uBITX (EEProm) control via Cat.
#ubitx
I created and posted uBITX Manager program yesterday.?
Originally it is a program I created and created for the firmware that is going to be released today. Maybe you like the original firmware or you are making your own firmware. So I wrote the code to control EEProm through CAT with minimal modification. The original source does not have EEProm control via CAT.?If you add 27 Lines to the original source or your source code as shown below, you will be able to backup or restore the transceiver's configuration files from other programs. The code below does not have bug fixes or other enhancements to CAT. It is just a code for controlling EEProm via CAT Below picture is an example of downloading the source from??and applying the 27 lines above. and communcation with uBITX --? Detailed firmware upgrade method and how to use uBITX Manager are posted on the link below. For those who do not have a arduino compile environment, I have compiled the original source code with only the above code. Best 73 KD8CEC / Ph.D ian lee kd8cec@... (my blog) |

I have been thinking of diode switching in the audio stages. The TX 12v can block the RX preamp and vice-versa. I have to get back to town to try! Raj At 09/01/2018, you wrote:

...and you probably don''t want to exceed 24 VDC anyway because of high voltage on the IRF510 MOSFETs under any sort of bad VSWR condition. BTW - those DC to DC converters for $4 are pretty small and could easily fit on the back panel (after a bigger heat sink).?

Re: My Bitx40
Dave Bottom
Mike, RE your BITX40. If you are using an Electret Mic.? Do you have voltage across the Mic element.? If no Mic BIAS, there will be no output.?? On the uBITX there is a 4.7K ohm resistor from 12V line to the Mic element Mic+ side (they are polarized), Mic- to Ground, as this powers the FET inside the Electret Mic. Dave WI6R On Mon, Jan 8, 2018 at 12:49 PM, Michael Davis <maddmd818@...> wrote: It seems like everyone is now focused on ubitx. I hope someone can assist me in getting my "old" bitx 40 up and running again. It has been down (receiving great, no transmit) for a few months. Today I decided to tackle it. Got a good light and a magnifier. I took voltage readings and compared them to Randy's voltage chart. Only 2 slight differences. Q15 gate reads .3vdc in receive normal in transmit and Q16 emitter reads .01 vdc in transmit normal in receive. When I check current in the PA power feed line all is normal but no increase in current drawn when I HALLOWWW. The PA bias setting is 120ma and I haven't messed with R136. Not sure how to set that anyway. I've checked continuity in my microphone line and temporarily changed mic elements. I've tried tracing the audio input circuit but dont have the right equipment to do an audio signal trace or inject an audio signal in the audio input circuit. Relay clicks sound normal upon PTT. Jerry Gaffke has published some nice troubleshooting information, but no luck so far. I think it may be something obvious. It worked when I last used it and didn't when I turned it on a month later. Help!? Thanks, Mike --

Re: Chirp support for uBitx (was: Re: [BITX20] Implement a uBITX Memory Manager Program)
The current uBITX source does not have instructions to control memory yet. So I extended the CAT protocol to read and write memory for uBITX. uBITX can use 0 ~ 1023 EEPROM based on Arduino Nano.If uBITX is the only extension to the protocol, it does not matter what program it is. Ham radio deluxe and hamlib all use memory access protocol.?The same is true of my program, and so is chirp. uBITX can simply extend the protocol (very easy - Actually, I wrote 20 lines of code.), it will be accessible from many software. The program I created will be one of them. I think it's important to put an extension protocol in uBITX and I do not think it's important what programs use it. If you support uBITX in chirp, it is a good thing. 2018-01-09 5:40 GMT+09:00 Pavel Milanes Costa <pavelmc@...>:

Re: Implement a uBITX Memory Manager Program
I was able to put memory control commands in a few lines of code simply. Anyone can easily control existing programs with uBITX. 2018-01-09 3:09 GMT+09:00 Art Howard <k0kuk.vhf@...>:

Re: Implement a uBITX Memory Manager Program
of course. Compatibility with wsjtx was completed two weeks ago. Those who have already done beta testing are still using my firmware and wsjtx together. Especially for wsjtx, we also tested raspberry as Linux with Windows based test. Please click on the link below. Windows :? Linux (Raspberry pi) : However, in order to communicate smoothly with a digital communication program, other parts must be modified with ubitx_cat. This is because the current uBITX firmware is single thread. should use interrupts or simmilar Multi thread. I have been in the field of microcomputing for a long time, but I've been using the arduino program for the first time. Interrupts should understand the system because it considers the pending time and so on. So I made it behave like a multithread, so I had no problem communicating with wsjtx, fldigi, etc. DE KD8CEC 2018-01-09 3:19 GMT+09:00 Ashhar Farhan <farhanbox@...>:
