Re: New ham, Ubitx issues

Mark - I think he does. says
Attaining honours scores (i.e.?80% or above) on the Basic examination, or attaining qualifications in addition to the Basic Amateur Certificate will grant the amateur certificate holder additional operating privileges as specified in , including full access to the amateur frequency bands below 30?MHz (i.e. high frequency?(HF)).Dayne - FT8 (among many digital modes) runs the radio pretty hard, since it transmits for long periods of time with lots of modulation. Definitely a good stress test, but unfortunate that it may have overstressed one of the amps. I'm not sure what input voltage you're running at, but you could try reducing your input voltage, which will reduce the final power, and subsequently put less stress on the finals. I haven't measured my v6's current, but both of my finals get warm fairly quickly when I continuously transmit into a dummy load, so it definitely sounds like you may have an issue. Reed |

Hi Dayne,
I would redo the bias setting in the finals. There should be instructions for that on ubitx.net or on the list here.? Congrats on your new license! ?I ?wondering however if your current level allows you to operate a kit radio like the ubitx? ? 73, Mark |

Re: ubitx #v6 Screen Speed Mod, and interrupt driven encoder wheel mod
#v6
Hi Thomas,
I use vscode too, but currently use the "Arduino for visual studio code" plugin, rather than the PlatformIO plugin. However, new tooling on branches that have no relation to Mark's interrupt-based encoder changes seems rather off topic for this thread. Perhaps you could start a new thread to discuss your PlatformIO port? I'm interested in making development easy, but I don't want to hijack this thread with that discussion. I would be happy to discuss further in another thread. Reed |

Hi Mark,
Can you create a new branch for your changes (as mentioned in /g/BITX20/message/74898) and then make a pull request to my master branch? I could just copy your code into it, but then you won't be in the repo commits chain, and I want you to get credit for contributing :) Reed |

New ham, Ubitx issues
#ubitx
Well after many years of wanting to do it I finally took the test and passed with 87/100 questions! That gives me Basic with Honours up here in Canada, which means I have access to all bands.
Of course, now after being issued my callsign today while I was at work I was eager to get on the air, and finally try out the transmit on my ubitx (I've been listening for a while now). To make a long story short, I've messed something up. I think I may have blew the finals (IRF510) on my V4 board by running an unmatched antenna (like I forgot to tune it, and tried FT8). I touched the heatsinks with my fingers after a few cq calls on FT8, the first one (closest to the power plug) was cold, not warm at all, and the second one (closest to the antenna jack) was cooking hot! too hot to put my finger on! So I attached a dummy load and wired in my meter to check how much amps it was pulling, and I got 1.3A without speaking into the MIC just on key down. Idle is around 370mA which is about right seeing as I have the nextion display and second arduino board. I don't have any spare IRF510's, and I've read that the IRF520's I have wont work, but I would like to be sure this is the problem before I swap them out. To troubleshoot I tried swapping the IRF510s on the board thinking that now maybe the one closer to the power input plug would get hot, but this wasn't the case, the one closer to the antenna still got hot. Is this bad finals? or is there something else I should look at also. Thanks! Dayne VE7DNT |

Rob,
Don't talk sanity in the asylum. Why NOT use the back pins/ports? Pull off the soldered on Key connector PCB.? Find one that you can? mount flipped. The stock one might be close, but the clear side is a little thicker. Dah, Dit to the back ports.? Find a good ground.? No new holes or monkey snot needed.? Irony is that Most hams or budding hams can solder a wire to a connector, but it does take more skill to remove a TRS socket from a PCB. (or I'll take a chance with something I can cheaply replace, but on a new shinny board?? I was that way with the audio amp on my V3, but it had to be done; and nothing was harmed) I haven't looked at the Skunkwerks code, but I believe they previously implemented interrupt driven inputs for the key. (timer or hardware based I don't know). I ass_u_me they did for the T4, since Jim has reported excellent keying results. Jim et al did quick work in offering a swizzler, and over Chirstmas.? To boot, the price with shipping is incredibly fair.? I 'get' how they tried to keep it just plug and play with A6. The ADC on that "T4" chip is not great. But in the days of cheap processors with available ports, a 3 level analog key input is? <insert_word>? For the V3,4,5, it would have been a small cost adder to go directly to an I2C display (although pushing further past the target price) and freed those ports to better handle a key. I don't mean to hijack a Jim thread, but I think you have more of a winner than has been conveyed by your posts, even with a rev1 adapter. 1. no hardware mods required: -> this is what you can do. 2. simple hardware modes: -> this is what you can do. (and how your if still shiny case looks) |

If you are using the TSW T4 adapter then that keyer

Replying to myself here now that I've re-read Jim's post, looks like once the V5 code gets the V6 keyer, then all of my previous comments are mostly moot anyway... The new pins on the adaptor board take care of the keyer, and then PTT and key share the existing PTT line.? A6 becomes an open (digital or analog) pin.
Looking forward to the V5-compatible code, and your new Raduino replacement! |

Jim,
You mentioned leaving the A6 wire disconnected... With a V5 board, I just need to NOT connect A6 to the resistive divider and/or pullup resistor for the CW key the way I did previously, right?? Granted, there will be some software modifications required for this, but my thought is: - All I/O pins on Teensy 4 can be used as digital pins. so (unless you're using pins as analog in order to get more controls out of one pin, a la current uBITX) there's no need to use the pins in analog mode for inherently digital I/O.? (If I recall, one reason that the CW key is used as an analog pin is because it has to be, i.e. A6 and A7 on the Nano are analog-only pins, whereas this is not a Teensy limitation.) - So, I can use two pins to solve all my CW and PTT needs, by tying their usage to mode, and then using them as digital pins.? So all of the ADC questions become moot. CW Mode: - Use key line as straight key input, or as dits for keyer - Use PTT line as dahs for keyer SSB Mode: - Ignore key line (or maybe use as a tune button, i.e. straight key) - Use PTT line as PTT Future FSK/RTTY Mode: - Use key line as "shift" indicator - Use PTT line to transmit I'd also note, for anyone willing to solder things to their Teensy, that there are an additional 10 I/O "pins" accessible via pads on the bottom of the Teensy 4. Ripe for taking advantage of the extra MHz on the Teensy to implement new functions... |

Re: uBitx microphone wire up
Pin 1 - Ground This is the ¡°conventional¡± wiring for 4-pin microphone plugs (and would accept a Cobra CB microphone). Make sure that your chassis connector is wired to match. ? |

Re: Very low ssb output for v5
Thomas, et al,
"Spectroid" by Carl Reinke, or any audio spectrum display available for a smart-phone or tablet, works. While I applaud HF Signals for making a utility available for the purpose, it's chiefly just a graphic display of the audible sound range.? You'll have to self-impose the 300 - 3,000 hz SSB window on the display, doing your best to set the BFO to fill that range more or less equally.? Me? I like to put just a little higher than lower by a thin margin so as to drop my voice lows and favor the highs,? for punch though the QRN.? Ted K3RTA |

Re: Very low ssb output for v5
Do you have a microphone attached to the device you are using to access the web page?? It will not work without a mic, and it will not give you a reason, just a static page without the graphics.
If you have a smart phone or tablet, those will work as well and will have a mic. 73 Evan AC9TU |
