Thanks for your input Justin. In my case, the problem was definitely cased by the wrong orientation of the Nano pins, thereby causing a short to ground. Now that I have a new Nano onto which I have soldered pins in the same orientation as the original Nano that came with the uBitx, no further problems. In summary, the problem was not the current draw of the Nextion, but rather the short caused by the Nano not being oriented in the correct direction in its socket on the Raduino board.

Re: Ubitx v4 transmitting moves pll on 10m
Hi Curt.? Yes, this happens to me on 40 m and 17 m, but not on 20 m.? It only happens on digital modes, not on voice SSB.? It happens when I use SignaLink, but not when I use Easy Digi as an interphase for digital modes..? I have installed a common mode choke on the antenna coax, and ferrites on just about everything else.? As of yesterday, with careful tuning of the antenna, I haven't had a problem.? I haven't had this problem with my other transceivers, including SDR radios.? I hope you solve your problem. -----Original Message-----

I can't think how to search for any prior hits. Only on 10m ssb, just on a few frequencies, I call a station. He hears me but when I transmit again the menu comes up for a band change, and the rig had jumped off frequency. And then it happens again when I try again. Using a 2 element yagi well matched also with a feedpoint balun, so I suspect RF inside the case is getting into raduino. Anyone else experience this? Strange it doesn't happen on lower bands. Maybe I need to clean up the wiring. Anyway nice to make a few cqww contacts today on 10m where things were okay, on most frequencies.? |

Re: Arv is retiring
Arv was very kind helping this utter NOOB.? When I picked the uBITX as my gateway "rig" for amateur radio, I was driven by two principal considerations.?
First, the multiband, accessible, affordable, kit-based uBITX was an ideal platform for me, as a100% new amateur operator, to start to figure out which end is up.? (Still working on that actually, hahah).? Prior to my uBITX exposure,? I wasn't committed to the hobby at all, but I did want to see if amateur radio "worked" for me. Well, the results of that are in. Here I am. Second, I knew that I would need help.? If there are only three ways to do X, I will find the fourth way, and it will not work -- surprising only me. Hence the anticipated need for some hand holding. And I found that here in this group, and Arv was a pillar. I offer this affectionate note from June 2019 -- sincere and still true.? All of this is to say "thank you". ============= "Dear Arv Evans -- I have just read and re-read your post. I humbly share two thoughts with you. First, your ability to communicate effectively is unmatched - whoever got you started on writing did one heck of a job. I'm going to study your stuff, well done. And thank you very very much for your eloquent commentary.? You have written a guide for all of us. Second, you have spot on played out my experience with this group.? As a liberal arts major, I come this very technical field with more enthusiasm than expertise. For example: Based on the sheer volume of spurs/out of band comments, I was briefly obsessed with adding inductors (what ever they are?) and other little doohickeys to get the rig under control.? Then I learned to just keep the drive level down, and presto, I have a fully functioning, computer control, viable wonderful little kit radio.? Indeed, only the folks with issues tend to write.? Arv, you rock, thank you. Don" |

Arnie,
What size Nextion would also make a difference.? If you are using a relatively small Nextion then the super hot 7805 might not be normal.? I have a 3.2" and a 3.5" in my two V6s and with a heatsink on the 7805 I don't consider them to be running unusually hot.? A 7805 is a linear device and it will run pretty warm. This is just my opinion and have no factual tests to back it up! 73, Justin B. KI5GKD |

Arv also wrote to me suggesting that this was just around the corner. He is unusual in the way that he can make you feel in safe harbor no matter the nature of the question or statement. Like everyone else, I know that his wisdom and wit will be sorely missed.? Jack, W8TEE

It is with a tinge of sadness, nostalgia and much much gratefulness that I must announce that Arv, K7HKL is retiring from moderatorship of our group.
He and Hans, G0UPL started this group many many moons ago. I had announced the bitx design on rec.radio.amateur.homebrew and Hans got very interested and put together a group buy of the components. We needed a group to coordinate and He and Arv created the yahoo group for us all with Arv as the co-moderator.? Over the years, Arv has modulated, nurtured and mentored us in the group. His contribution to the bitx radios is immense. He did meticulous documentation of bitx radios and wrote the manuals as well helped the first bitx20a kits arrive in the market. His work is on? Apart from bitx he has wide ranging interests the range from Huff and Puff stabilizers (he and Hans are authorities on it) to solar power to Arduinos. He is not going anywhere, he will continue to be here in the group but his other interests and changing priorities compel him to hand over the charge. We added Sasi, VU2XZ as another moderator to the group. He has no business interest with any companies that sell bitx kits, he designed the LARC bitx boards, he is an immensly talented, quiet homebrewer who is also our Lamakaan Amateur Radio Club secretary.? Thanks Arv, we continue to celebrate and appreciate everything you have done for us all.? - f -- Jack, W8TEE |
