Hi Reed, I was going to point out that without the feet it will fit in that 3.5 inch height. I hope it is not too wide to fit a rack <evil grin>. 73, Bill KU8H bark less - wag more

Also note that the feet are optional. Reed

Maybe this pic will help. Reed

Our club is considering several of these xcievers for our emergency team members. One will be rack mounted in a van and another permanently installed in a rack at the Comm Center and one or two more

Most should know this but do not try to measure voltages on the power out amp transistors and key the transmitter at the same time. I did this once on an MFJ 40M SSB QRP rig, across a choke, and the

hello. I try both.. Last, with this faults.. ? Error at line 1049 in file ubitx_tft_320240.ino: ? 'class TFT_eSPI' has no member named 'getTouch' Compiling Failed regards Ken

I will assume that you have the input and output measurements reversed. Even with that modification, the output pin of U2 (the 78Lo5ACZ) should be 5volts +/- 0.15volt.? There is something wrong with

Hi Evan, Thanks for your help. It's okay. 73 Bora -- TB3EN From Turkey. Electronic Communication Technician, Member YM3KM.

Here are the measurements that I have. *INPUT: 7.87 * *OUTPUT: 12.85 * That may be backward as to what you were wanting, I determined the pins from the datasheet that I found here: LM 7800 Series Data

Hello Ken, do you use Arduino IDE or UECIDE? Ramón

Hello I am new to the ubitx project. I want to compile the esp32 project, but I have a problem finding the right libarys. Can you tell me which versions you used from where. Is it also possible to

There is a capacitor on the output of the LM386 audio amp, so not sure if it matters.? Wiring as Edward suggests would work, as long as it is a stereo plug. 73 Evan AC9TU

I stand corrected tip and ring are (+), sleeve (-) Ed N7SNT

The tip would be positive (+) audio, the ring negative (-) ground. Hope that helps you. Ed N7SNT

The mono audio is connected to both the Tip and the Ring with the Sleeve being the ground return.? This was done so that you would hear the audio in both the left and right headphones when stereo

Trying to wire up and accessory filter to plug into the headphone jack on my V6. Is the headphone jack wiring sleeve(-)/tip(+) or ring(-)/tip(+)?

You are right Evan I was thinking V5. Your comments are spot on. Aaron, please disregard and follow Evan questions about the 12v on the finals. 73, John

Aaron, On the schematic, we are looking to verify that U2 is being supplied 12votls on TX, and regulating that down to 5volts on TX. On the actual board, I believe it is where the P1 CONN 01X03 lower

Ok I'm still learning this stuff and a lot of what you guys are saying has gone over my head. So please be patient with me. Evan: My pots are straight. Where would I find the Bias Regulator? John: I
