bitx40 displays version, hums, but does not receive
#bitx40help
#bitx40
#radiuno
Greetings, All!
I assembled my bitx40 and operated with it several times without any problems.? I then unhooked all the wires (just the ones with plugs) and set it aside so I could build an enclosure for it.? After finally getting it into a case, when I turned it on, the display was nothing but black boxes (two rows) and no sound came out of the radio.? I noticed the USB connector on the side of the arduino in the radio and tried to get it to connect to my computer.? It wouldn't communicate at all even though the red LED on it was illuminated. I bought a new arduino nano, loaded up the raduino sketch, removed the old arduino, and soldered the new one in its place (if I were smart, I would've put in pin headers).? When I power up the radio now, I still get two rows of black bars but if I view the screen from an angle, the display reads Raduino v1.27.7 and I do hear some "noise" coming out of the speaker but it doesn't sound like radio noise.? It's a sort of noisy hum.? The radio never displays a frequency at this point, it just stays on that version display. Does anyone have an idea of what might have gone wrong here? Thanks for your time! 73 DE KD5RYO |
Re: UBITX Current Production (spur fix ?)
#ubitx
My V3 board was equipped with the HFD27 relays.
I already took them out to switch to Axicom- might have been smarter to check first how bad the problems is. Good to know at least that the? HFD27 are probably an improvement.? |
Re: a simple spur fix
1. the raduino is shipped with a socketed nano. you can swap it for another (nano or anything else). 2. the tones are created by the variations in the 16 mhz oscillator crystal of the atmega. at times they drift downwards such that their harmonic beats with the 12 MHz BFO harmonics to create an audible tone. the way around this is to always keep the BFO further down from 12 MHz at appox 11.995 MHz so that the beat moves out of audible range. - f On Tue, Dec 11, 2018 at 8:21 AM Jerry Gaffke via Groups.Io <jgaffke=[email protected]> wrote: Most of us don't have tones from the 16mhz Nano processor clock since that ceramic |
Re: UBITX Current Production (spur fix ?)
#ubitx
I understand that you're accurately reporting the latest comment from Farhan.? My V3 board was equipped with Virtual? VRS2H-S-DC12V-C relays.? It looks like the HFD27 relays in the current board were an upgrade and/or replacement but aren't a result of improving crosstalk.? Mea culpa.

They don't appear to be anything special with regard to RF isolation, definitely not Axicom relays. My guess is these are still about the same as what has always shipped with the uBitx. And Farhan's message that you cite (62415) states: "The boards continued to ship with the same relays as some have also reported no difference with the new relay." I take that to mean that new uBitx boards continue to ship with no harmonic fix of any sort. Or any spur fix.

There's been no assessment yet on other mods that might mitigate spurs, and since there doesn't yet seem to be an assessment on the 'best' way to solve that problem, there likely aren't any spur fixes on production boards yet. |

resonanator is so inaccurate.. For those that do, just spend $3 on a different $3 Nano clone. A bit tough on a v3 uBitx, as the Nano was not socketed until v4. As of v4, the uBitx (and any Raduino) comes with the Nano socketed on the Raduino. Note that the header pins must be on the "wrong" side of the Nano, so order your Nano with header pins not yet soldered in place. Shipping without the Nano clone would probably cost more in trouble than the clone does. Give any spare clone away to some teenager bored with video games. I have not exhaustively evaluated all the various possible sources of birdies only addressed the ones I've heard to be problematic. Anything that creates 12 or 45mhz will be problematic, as that can sneak into the unshielded IF and create hetrodynes that always occur, no matter where you tune. The 4'th harmonic of 12mhz beating with the 3'rd harmonic of 16mhz (if your 16mhz resonator on the Nano just happens to be 16.000mhz) is especially weird, but if both 48mhz signals are present at the demodulator you will get audio tones. Lots and lots of birdies that you can tune through. You will likely hear a carrier at 25mhz, for example, from the si5351 reference oscillator. But only when receiving at 25mhz.? ? Also the 16mhz Nano processor clock.? But those (and many others) will only occur at specific spots on the dial. Unplug the antenna and tune around your favorite band, see what birdies you find.

A) Hi Clark, yes I recall there was an issue with the full swing vs low power with the ATmega644p/ATmega1284p the oscillator was interfering with the serial port in full power mode, it made for interesting times trying to use a serial bootloader. |

I ordered my 7" display using Jack's link on Nov 16 and it got here today.?? It took 24 days so if you play on building one you may want to order soon.

Re: FT8
The way this upgrade has been released noting the incompatability beteen 1.9 and 2.0 versions is problematic.
Plenty of FT8 signals on the scope - one decode the last two nights using 2.0. Switched back to 1.9 and everything is decoded. I want to make contacts, thats wasn't happening for me on 2.0, so why change. Seems 2.0 is vulnerable the network effect. 73 Simon |

Vince Vielhaber
I've been using 2.0 all day today. Lots of contacts around the globe. Any problems with it should be answered in the Getting Started guide, such as the one Art mentions below.

Memory manager
I've recently been using KD8CEC'S memory manager version 0.97 , Just learning my way around really , Today I started using version? 1.081 ... I've now got my S meter to work using the? LM-358 op amp circuit ... so good so far ... Trouble I've now got that I didn't have with version 0.97 is that when I write to Microbitx , For done teadon the sidebands now get flipped , LSB now becomes USB and visa-Versa ...? Luckily I saved a copy of an older? ?Micro-Bitx file, So I'm able to copy that back to the micro bits , It then all works as it should , But the S meter stops working as it's now turned off ... Does anyone know why the sidebands are getting reversed ? .... Is there an issue with Memory manager version 1.081 .....Thanks Gw0wvl ' Marc ' ... |

Re: FT8

With all the errors I am seeing today, I am afraid to upgrade. I am doing the grid chase and have been using 99.9% FT8.? If most people stay on 1.9, I feel like I am shooting myself in the foot. I was afraid of this happening. Especially this close to the end of a year long event that a lot of people have been chasing with FT8. Add to that the misc. errors that are coming up and I really don't have a good feeling. 73, Rocco On Mon, Dec 10, 2018 at 3:49 PM Anthony Luscre <k8zt73@...> wrote:

-----Original Message-----
From: joe@... To: wsjt-devel@... Sent: 2018-12-10 9:10:27 AM Subject: [wsjt-devel] WSJT-X 2.0.0: GA release The WSJT Development Group is pleased to announce the general availability (GA) release of WSJT-X Version 2.0.0. If you have been using version 1.9.1 or earlier, or one of the candidate releases v2.0.0-rc#, it's important to upgrade now.? The original protocols for FT8 and MSK144 are no longer supported.? With v1.9.1 and earlier you cannot communicate with WSJT-X 2.0 using these modes. We now recommend using WSJT-X 2.0 anywhere in the conventional FT8 and MSK144 sub-bands.? Everyone should upgrade to v2.0 by no later than January 1, 2019. NEW FEATURES IN WSJT-X 2.0 -------------------------- 1. Compound and nonstandard callsigns are automatically recognized and handled using new FT8 and MSK144 message formats. 2. The new FT8 protocol provides optimized message formats for North American VHF contests, European VHF contests, ARRL Field Day, and ARRL RTTY Roundup.? Similarly, the new MSK144 protocol provides optimized message formats for North American VHF and European VHF contests.? Full support is provided for "/R" and "/P" calls in the relevant contests. 3. The new protocols provide nearly equal (or better) sensitivity compared to the old ones, and lower false decode rates. 4. New logging features are provided for contesting and for "Fox" (DXpedition) mode.? Logging is optionally integrated with N1MM Logger+ and WriteLog. 5. Color highlighting of decoded messages provides worked-before status for callsigns, grid locators, DXCC entities, continents, CQ Zones, and ITU zones on a ¡°by band¡± and ¡°by mode¡± basis, and for stations that have uploaded their logs to Logbook of the World (LoTW) within a specified time interval. 6. The WSPR decoder now achieves decodes down to S/N = -31 dB.? For the particular benefit of LF/MF users, an option "No own call decodes" has been added. 7. The UDP messages sent to companion programs have been expanded and improved. A more detailed list of program changes can be found in the cumulative Release Notes: Upgrading from earlier versions of WSJT-X should be seamless.? There is no need to uninstall a previous version or move any files. Please do not continue to use any release candidate -- that is, any beta release with "-rc#" in the version name. Links to installation packages for Windows, Linux, and Macintosh are available here: You can also download the packages from our SourceForge site: / It may take a short time for the SourceForge site to be updated. We hope you will enjoy using WSJT-X Version 2.0.0. ????? -- 73, Joe, K1JT, for the WSJT Development Group _______________________________________________ wsjt-devel mailing list wsjt-devel@... ?
