Re: Funtronics uBitx digi interface installation in V6
last point of my opinion, and i apologize if i come across as a hater,but im not.
Friend of mine is a no code ham. he learned the basics of the code and uses a decoder to decode the cw. he sends about 20 wpm with his paddle ,which doesnt make sense because he cant copy past 6 wpm with his ears. i proved this with on air copy. doing about 8 to 10 wpm. he said he couldnt copy it even though he sends really fast. he doesnt try to decode the cw in his head since the decoder is doing it for him. I told him if you can send 20wpm you should be able to receive faster than 8. no way. i had 3 other hams verify this. WEIRD,BUT TRUE.He stated"why learn to copy faster when i have my decoder. he uses software to do this on his computer.Im not knocking him,but i did explain the reasonings of not using one.happy he is trying cw and using it,but the decoder gives him a false sense of accomplishment. he has been using this setup for several years and still cant copy faster than about 6 wpm. WEIRD ISNT IT. My friend is an engineer for 30 years, very very smart, but has been ruined by his decoder. HI HI.3 of us have been working with him with various,various methods, and we even paid for his classes,etc just to be friendly. he went,but the instructor stated "ive never seen anyone who can send 20wpm and not copy by ear at least over 6 wpm. He refuses to try to fill his head with the decode but can send 20 wpm with his paddle. foud out some of his secret. he uses precanned groups of statements. qth,radio,rst,etc. He goes thro the motions and then after his decoder decodes the other hams info he clicks the statements he wants sent next,it also includes the 73,etc. .very canned,very brief, using decoder and software on computer.? is he running cw? yes,but with an analog radio and no goodies attached to it,like a decoder,he is dead in the water without it.Ive praised him over and over for trying CW,but He stated "i can make 1000s of cw contacts and basically not even know CW"The computer and decoder will do it all for me.His words,not mine.Also his paddle is basically for looks. he uses computer control to do the sending 99% of the time. please inform the other end u are using one if you cant decode the signals when adjacent qrn,qrm,qsb affects it or you are in a pileup.This leads to abrupt endings of qsos. or qsos that really seem robot operated.I ran into this when doing ft8. Someone calling cq forever and not responding to others who respond to their CQ. just my own opinion of it. 73 David ac9xh |

The 4SQRP people have the Beta boards from China and are starting to test them. I don't have a firm date, but it looks like late Sept, early Oct to me, but that's just a guess. Jack, W8TEE

David:
I think you read what I was saying incorrectly. I said a practice session is done with the eyes closed. If the student is doing that, they're not using the decoder. However, if they "get lost", the can open their eyes, see what tripped them up, and close their eyes again and soldier on. I think it can lessen the frustration of getting started learning Morse. I'm not pushing the T41 decoder. Indeed, you can turn it off and not even know it's there. It is not a feature of the T41 that would make anyone buy or not buy it, so I really don't have a stake in the decoder. There's nothing wrong with us disagreeing on this. A student just getting started could try both approaches and see what works best for them. No one solution fits all. Jack, W8TEE |

Re: Funtronics uBitx digi interface installation in V6
Jack,
love your books and projects, but i have to disagree with your philosophy.If you become dependant on decoders, you will have a harder time of speeding up your copy. Ive spent alot of time teaching code. and most who have used decoders,never get past the hurtle that the decoders present. I know you are pushing it since its in you rig, but i definitely disagree.Everyone has a point, an opinion, and i gave mine. I wont change my beliefs because others? say? they disagree,or "make a point". Sorry jack but i dont see eye to eye on this with you or anyone else for that matter. Guess its because i dont have a stake in the game.And there are 1000s that agree with me ,just not on this particular forum. 73 David ac9xh |

Re: sBITX waiting for shipping details
Mark Earnest
Partial Kit #77 showed in Pittsburgh in 10 days from shipping notification.? It was on the air in less than an hour. This thing is sweet. I haven't replaced the voltage regulator yet but I have a dozen or so of them from Amazon and I'll probably replace the LM338 before trying anything more than 10 watts just to be safe (I want to enjoy this working before I take a soldering iron to it :) |

Re: #sbitx: Raspberry Pi Heatsink?
I am convinced by now that heatsinks are unnecessary - vcgencmd measure_temp tells me the RPI measures 56.4c after 5 hours being switched on, surrouding is about 26c.

Re: Funtronics uBitx digi interface installation in V6
I installed the Funtronix board and it works well for FT8. There¡¯s plenty of room in the InKit enclosure for the 5 inch Nextion screen, as well as other mods ( I have a second nano for the Nextion s-meter, also another mod for an analog s-meter, an AGC, a broadcast band filter which is an absolute must in Los Angeles, and other mods).

Try reducing your 1000uF down to 10uF. Of course, the capacitor comes after the choke from your power source (L-C). On Tue, Aug 16, 2022 at 10:57 AM Scott KE8KYP <scott_massey@...> wrote: Hi Guys, -- Jerry, AC9NM ÊÖÖеÄÄñÔÚ¹àľ´ÔÖÐÖµÁ½¸ö |

Re: DAYLIGHT RADIO - PLASTIC TOROID MASTER
Here's some info on loss tangent from David W. Knight, G3YNH, site He mentions the microwave heating test is invalid because the properties of a material at microwave frequencies may be very different than at HF. Here's a clip of the info he provides on loss tangent by material type. Since I have some blue PEX tubing, which is cross-linked polyethylene and PE is listed as excellent,? I thought of making a trial toroid from 1/2 inch PEX. It's 22mm x 10mm x 10 mm (7/8" x 3/8" x 3/8") in size. Low res photo attached. It may be easier to stuff a 1/2" piece inside a 3/4" or 1" piece of PEX to increase the wall thickness. E. Material selection by loss tangent.

David: ...decoders for cw are an insult to the cw community... I disagree. I was licensed in 1954, so had to learn CW and, while that's not the case today, I think it's a shame that all hams don't know CW. Regardless, my guess is that less than 10% of those licensed after 2006 know CW. Al (AC8GY) and I have spent a lot of time on the T41-EP SDT and one of its features is the ALP CW Decoder. I spent almost 5 months with Al tweaking the decoder to make it as robust as I possibly could. We presented a paper last May at FDIM on its algorithm. It works pretty well on a good signal. And here's my point: If you are trying to learn CW, a decoder can be a useful learning tool. I encourage students to close their eyes and copy the code in their head. Perhaps starting out with W1AW practice session at whatever speed you can currently copy. If your "head copy" on the back of your eyelids messes up, you can open them up and see what you missed displayed on the T41 display. That might give you clues as to nettlesome patterns that are tripping you up. In such practice sessions, a decoder can be very helpful. Even if you're experienced with CW, it can be useful (e.g., a cell phone ring and you lose concentration for a few characters). Indeed, I would hope the CW community sees the ALP and other decoders as a potential tool that can expand the CW base. Jack, W8TEE

Re: #sbitx mod
#sBitx
Hi Guys,
I picked up some of the buck regulators from Amazon that Ashhar originally recommended.? After reading this thread, with regard to switching noise concerns, I built an input LC low pass filter to "head off" potential noise issues.? I've not installed it the transceiver (waiting for replacement IFRZ24 transistors to do the work all at once), but I performed some bench tests.?? Out of my junk drawer, I found a blue toroid and wound it with 36 turns of 22ga magnetic wire.? I made a static measurement of 4.98uH of the choke and added it with a 1000uF, 25v electrolytic to make an input low pass filter.? The DigiKey Low Pass Filter Calculator calculated a -3db cutoff frequency of 2255.3059Hz.? On the output, I added a 470uF 16v electrolytic to reduce some of the switching noise. The output waveform looks good.? The stability is good but there is about a 30-60mV ripple @ ~208KHz.? My anticipation is this will work fine but before I install, I would appreciate your comments. Thanks, Scott ![]() ![]() ?? |

Re: why uBitx uses "inverted" pinout of arduino nano
Hello,
In theory, it is advisable to weld the arduino on the side opposite the components. This to avoid capturing too much interference on components.
I¡¯ve read about how much....... So that may explain an inverted pinout.? I also believe that it is automatically inverted in Kicad models.

Re: Funtronics uBitx digi interface installation in V6
I guess I'm late to the party and have no idea what the Funtronics board is for.? I have been running digital on my V6 since last fall with no hardware mods just the 'CEC firmware and using the Yaesu? FT-817 selection for CAT control.
What else does this board do?? I'm not inclined to watch a youtube video and chew up what remains of my hot-spot data since I am off-grid right now... 73, Justin B. |
