Do you have interest in a swap with an unbuilt V3 Kit with the enclose blue. I purchased the kit but with a stroke I am unable to Build, I I will pay shipping for mine to you. If needed I will send you pictures Bill WF9M On May 12, 2020 at 11:50 AM john <johnmb@...> wrote: ? |
Re: 160m filter
awesome. i heard doug demaw was a great 160m operator. he built many 160m qrp rigs. at times, i want to build a cw twin set (separate tx and rx) with the mandatory 10 watts output. all vfo, all cw. i guess it would be fun to see where analog takes us in this age. - f On Tue, May 12, 2020 at 10:37 PM _Dave_ AD0B <davesters@...> wrote: Hi Ashhar,? |
Re: 160m filter
Hi Ashhar,?
I have used 160 twice on"work all states" type of nets,?this spring before they quit for the season. I got 11 contacts from as far away as about 1200 miles.? Running a multi wavelength loop and it is generally quiet.? Using my V3.? Many hams on those nets ran power, but I got respect. Hopefully others have ran 160 on ubitx . 73 Dave |
FS: uBit x V-1.5 yrs ago (V3 or V4?)

I built a unit (I think it's a V3) with the factory case. I think I neatly installed the AGC mod. I know it works on CW and I know it hears well. I ASSUME it works on SSB but I'm a CW op so I'm not positive.?? I think it's well built , it works and i'll ship it to your US address for $100.? ? |

There is nothing wrong with old just because of age. It's only a number. Tell me about it! And that applies to the old-dog-new-tricks excuse some use for not trying the newer technology (e.g., SMD versus thru-hole kits). I've got shoes older than many people reading this post, but I still try to keep up. Almost always, it's worth the effort. Jack, W8TEE

Hi Bill,
That's a good response and additional use for the V4. Think external things have interfered with a clear thought process. Tired as most of staying home, trying to find meaningful things to occupy the time. Watching the depressive news, and other sources input is a waste of time. This has a tendency to put one under the rug deeper. Was as looking longly at the past rigs used or owned, and trying to relive the past. Remembering how much fun amateur radio was, the excitement of sending or receiving QSL cards for contacts, and the simple modes of operation with a modest station. These are good memories from my past QTHs. That to me was, is, and will continue the essence of amateur radio. Though others would tend to disagree, opting for the latest, and greatest equipment, or newest operating modes. Guess an old putz, I'll be.. Hi hi... 73, Wes KH2EE |
Re: 160m filter
Dave, the main reason why I had to skip the LPF was the lack of extra pins on the Arduino. I have never operated the top band though i am very intrigued by it. - f On Tue 12 May, 2020, 5:32 PM _Dave_ AD0B, <davesters@...> wrote: ?I finally put on my low pass filter for 160 on thingiverse.?? |

?I finally put on my low pass filter for 160 on thingiverse.??
?This was my original post here.?/g/BITX20/message/77231? ?Obviously this is a design that you need to hook between the radio and antenna when using 160 and remove for other bands. It seems like such a simple thing that Ashar might include as a kit and auto switch it. I am sure it could be made more compact with toroids although I was surprised at how compact it is even with air core. -- 73 Dave |

Could it be that a new station started doing JT65 near you? 7.076MHz is the "default" frequency for JT65 in the US (). Or are you hearing that same sound on other frequencies too?

Sergio I am quite sure that your problem is caused by a not correct calibration of the transceiver, I suffer the same last month, try 15 for the calibration and 11.056,6 for the BFO if you have a v5 uBITX.

Thanks Reed for your input. I will stick to the external LP filter. I really appreciate your efforts in the V 1.5. Barry On Mon, May 11, 2020, 11:33 PM Reed N <greenkid336600+groupsio@...> wrote: Hi Barry, |

It's usually best to put separate inquiries on separate threads so that they're all easier to follow, so I hope you don't mind that I'm responding here, instead of Darwin's thread about TFT screen upgrades. To answer your question, if you look in the tuner.cpp file, line 41, you'll see a function called "setTXFilters". Inside that function, you should see thresholds, and the filter selections they activate. Note that as the function name implies, these filters are used for transmitting, but they are NOT used for receiving. If you look at the uBiTX v6 schematic (downloadable here: ) you'll see these TX filters on the right hand side, with signals of FLA, FLB, and FLC controlling them. For receiving, there's only one RF filter and two IF filters, and they're all always in place - there's no software control, other than adjusting the IF frequencies. You can see this in the schematic, and also in top of the block diagram found at . So if you're getting SW interference, an external filter (like you've tried) or doing some radio surgery to add an additional internal filter are the only solutions I'm aware of. Reed Reed what changes would need to be done to constantly select the band pass filters during rx in your latest and greatest v,1.5? |
Alright. Darwin - on my Github, there's now a branch called "input_output_debug". Select it, download it (or git fetch, if you prefer), and load it onto your radio. This software does NOT work as a radio, but may help in debugging.
This branch doesn't activate any of the normal functions or menus while running, but rather produces output from inputs fairly directly. When you push the knob button, you should get a beep. A long press will get you a different beep. Touching the touch screen will produce a different beep. Long pressing the touch screen will generate yet another kind of beep. Turning the knob will produce different kinds of beeps depending on which direction you turn it, and how fast you turn it. In addition to all the beeping, on the screen there are two squares drawn that light up with the button presses (black normally, white when short pressed, red when long pressed), and two text boxes indicating how far the knob has been turned recently, and what the last point (in pixel coordinates) touched was. Finally, all of the input data (button presses, touch presses, touch locations, and knob turns) are streamed out on the serial port, so even if your screen and speaker don't work, you should be able to get data out on the serial monitor with a baud rate of 38400. Give it a shot, and report back on what you observe. What makes it beep? What doesn't? What data do you get on the serial output? Do you get anything on screen? Reed |

Don't bury that radio too deep. I have (ab)used my V3 as an LM. It works a treat in that role. Don't power the finals and it will not blow out any receiver you are using it to trace. As with the old time LMs it really isn't necessary to connect the uBitX output to anything. But I have hung a scope probe on the BNC connector and sniffed around inside 'out of sorts' receivers. It would not be good to accidentally dump ten watts of RF into oneof those and make more fodder for the dust bin! Murphy you know. Maybe a good, used ricebox for your mobile:) 73, Bill KU8H On 5/11/20 8:23 PM, Richard West via groups.io wrote:
