Evan, yes, I looked, but it’s more about reducing consumption. On my µBitx, I can pull at least 5 amps. A friend gave me, a torus F114. I measured, 0.7 ohm and 2.32mHenry. I will test tomorrow if

Hi Evan, Thank you for the reply and all the other contributions you have made to the group. Just checked Q90 and it's lost interest in life... B 0.898V C 0,89V and E 11.51V. Replacements should be

As mentioned in original post, CW works fine gives 5w out on 40m. Yes i am aware of static voltages. I will try to measure them without blowing anything.😀😀

Rx seems ok. Some stations come strong. Some weak. Antenna is EFHW in sloper configuration. Dont know how sensitive is the ubitx reciver. But i can definitely hear the strong stations clearly some 5/9

Gerard, Here is a link to KD8CEC's blog on how to dim the LCD backlight. It is at the end of the long blog. http://www.hamskey.com/2018/06/nextion-tjc-character-lcd-current.html He used a resistor(s)

R. Tyson, The major differences between the model 4 and model 5 uBITX are in the BiDi amps Q10, 11, 12, 20, 21, and 22. Those 6 transistors are BFR93W instead of the 2n3904. As such the voltages

Hi all, First of all... I would like to thank you for posting the list of transistor voltages for a normally working uBitX. I note these are for the version 4 but would I be right in assuming that

Hello, Nextion noise suppression choke: I find this answer on https://ubitx.net/category/nextion-display/ Talmadge Huckabee suggests that a good source for a Nextion noise reducer choke (2.5mh) is to

Hi On my v6 80 m worked fine, but 20 m was warbling. I tuned and then both worked, pretty straight forward.. Best regards, Ole

What do you mean? The V6 should be supplied from HF signals already calibrated - At least mine was and did not need any adjustment - anyone building one should confirm that it works before changing

Evan, I need to take a closer look at this. Indeed as can be seen on picture , I had planned a 5v regulator to for the screen (With self and capacitors). My self may not be strong enough and the

Hello Jer The v6 kit I received in late August came with the baofeng mic. Yes I only had to remove one surface mount resistor, no other surface mount devices were on my mic pc board,if yours has

Aaron, As far as I know, there is only one size for the transistor, unlike for discrete parts like resistors and capacitors. I went to Mouser and looked up the 2n3904 and selected the SMD part. Here

I have tried to join Antuino group but get a message that I already have joined. When I try to post, the message bounces sayng I am not a member! I am having a problem with a brand new Antuino that

Ok thanks for all of the help Evan. Just a few noob questions for you. I have seen that the SMD stuff comes in different sizes. What size do I need to replace Q90? When you are talking about Back to

Gerard, There is an issue with the Nextion screen backlight. It is common on most if not all of them. The issue is that the pulse width modulation used to dime the screen causes noise that gets back

I was having some issues with RF getting on my mic cable and making the radio change frequency using the little Baofeng mic. I put a .01u cap on the mic audio to ground in the radio. Still had
