A low power supply voltage can cause electronics to do unexpected things. but pretty much never causes damage.? ?When bringing up a new board,? you are far more likely to cause damage by bringing

It's already up to $52 plus shipping. I have an untouched, unbuilt v3 still in the shipping box. Never opened, never touched by a soldering iron. What would be a fair price? Any interest here? Clay

Anyone wanting the TSW Teensy 4.1 Raduino kit, they are still available.? We have located a source of 5351 clock/VFO chips and it turns out that Mouser electronics, at least, has over 700 Teensy

Reed, I want to thank you for the excellent job you did on the manual. It was easy to read and the steps for updating the firmware were easy to follow. I ran into no hitches even though I had no

Great write up Reed, This deep work and you explained it so well. Like me, I am sure many of us here have picked up so much from it all. I was always curious of how the totem pole worked with varying

Over at /g/BITX20/topic/ubitx_v6_specifications/82557868 I saw some folks wondering how in the world something could be damaged by undervoltage, since as we all know, when things are

Hi all, Thank you for all for your information and comments. Bill, I'm not sure why there could be damage to a display if the voltage dropped. On the enclosed paperwork, that came with the Nextion

Bought a very nice chassis and ordered a ver 6 board. Looking to buy a 5" Nextion display....what is the best model number? I see a few choices on amazon. Thank you - Mike

At this price... Go for it, it’s not even the price of spare parts. There may be only one transistor to change?? Too bad no shipping to France.

Thanks, I will be doing that. Earl Cox? KB5UEW?Reply or E-mail me at:? kb5uew@...

I would not have posted anything, were I not satisfied with the product...likely not much good for small values of caps (but what is ?)...works just fine for 10 nF and stuff in that area Jim

Someone's selling a uBitX V3 in a case on ebay. At this time the bidding is only at 12.50. Not mine, just sharing the info. https://www.ebay.com/itm/265148896485 Vince. -- K8ZW

I won't say for sure, but possibly some devices may draw excessive current if the voltage is too low.? I happen to know that some motor-driven equipment will be damaged by under-voltage.? The motor

Hi Robert... .....Earl, The quietest power source for radios are plain batteries. I have some vacuum tube gear I run on batteries and that is one of two major reasons why. Of course my solid state

Robert, I can answer the above question:? The stock v6 display draws about 80ma.? the 5" Nextion display draws about 410ma.? You definitely need a separate power source for the 5" Nexti

Most of the power is consumed by the digital display. There is a brutal way to add an on/off switch between the LED pin of the tft board and the Raduino board. That should shave off the power

No apology needed Robert. Got the info I needed and much more. thanks. Earl Cox? KB5UEW?Reply or E-mail me at:? kb5uew@...

My uBITX older version works well on a 3A battery source, regulated 12V. If you want some extra room, you might want a 3.5 or 4A capability.? Earl Cox? KB5UEW?Reply or E-mail me at:?

Found some PL906090 6AH 3.7V li batteries, each weighing 3.5oz. #.5*3=10.5oz = 12V@6Ah. 10.5oz*4 = 42oz = 24AH if I did that right. 42oz/16=2.625 lbs. + case. On testing these, they seem to be close

Hi All, Thanks for the information everyone. That’s about what I figured a 4a power supply would be the safest, with some room for improvements, like a 5” display with it's own power supply.
