hello, I had already asked the question, but I did not get an answer on the schematic of ubitx 6, there are like 2 transistors mounted in parrallele on the final stage We see an IRF510 and a RD15HV in

Hello Dennis, Thank you for your information So far I don’t have a second Nextion. (In 2021?) So my edit would be a main 5-inch Nextion and a 3.2-inch Nextion in secondary. So it should work. Afterwar

Evan, OK Look here, i like colors on the second Nextion An other tft file? https://www.youtube.com/watch?v=mFwCggew55Y https://www.youtube.com/watch?v=nZ-EF19BtWw My idea is to have main screen on a f

Hello, I was looking at this documentation for my information and I have a doubt about the connection. http://www.hamskey.com/2019/04/installing-swr-and-rf-power-sensor-in.html Look at the comments..

Hello, If you inject a signal of 15mhz near the antenna by radiation (Mid 0 to 30MHZ) and watch the beat up to 0 at the oscilloscope just before the SSB filter (or After the 45mhz filter), you must be

Hello, The other time when I did a search on E.. Y, with the keyword Ubitx, I came across this. A filter, but I don’t know any more... https://www.ebay.fr/itm/uBitx-HPF-High-Pass-Filter-Mod-Board-3-5M

Hello, the project of a Ubitx in module has already been evoked see here: https://groups.io/g/BITX20/topic/71823431 cdt

Gordon, Any assembly can be cut into pieces. Advantage, one can change/ improve a module at its convenience. The best system (in my opinion) is a board with main functions and a bus with several conne

Thanks, Evan, you’re always on the cutting edge of information. I note this aside for my next changes Have a good weekend

Hello, Thanks An other link https://ubitx.net/tag/aj6cu/ cdt

Re. Yes the advantage with UV is that you can make a precision PCB . The problem is that to find the right exposure and bathing time in the perchlorure. I missed several PCB like that. So I tried the

Hello, If it is a homebrew building, may you put some pictures. I like to see personal achievements. cdt

Hello, Several decades ago, we made a PCB with a pen, then pellets and tape. Today we can make a nice PCB with software. I used simple free software, where you have to connect all the tracks manually

Hello, Yes, Yes, I made a collection of favorites on the subject. I wonder if my order of this N7DDC antenna tuner is useful for a LOOP antenna. A priori NO, because this does not affect the main loop

Otherwise, I wonder if the change in the value of the capacitor on the LOOP antenna, will not actually cause a runaway system....because autmatic Tuner will adapt new value, etc Another track to dig d

Hello, look the datasheet of this automatic tuner antenna https://static-eu.insales.ru/images/products/1/959/266920895/2.jpg When I look at this diagram, we see a set of selfs and capacitors that are

Evan, Thanks You have also this one http://f6hcc.free.fr/hw8.htm With some modifications to do, etc but it's an old time!!! LOL Use ggogle translate for english Have a nice day cdt

hello, Hw-8. I dont know what is it? Is it a fabrication of this style? A Heathkit year 80? I would really like to see a similarly placed, larger layout with through hole components >>> That exist...

Hello, I don’t know if we’re allowed to make that kind of request. I still ask the question. I made a Ubitx prototype that works very well in classic mode. (discretes components) I wanted to know if t

Hello, I just need a confirmation when i look his Ubitx Is the version 1.2CEC different in display when we choose the version Ubitx5 compared to the previous ones (3,4)? I found a different display th
