Nobody mentioned setting the audio levels? Set the speaker audio to a very low level and watch the power out on a power meter (you really ought to get one) step it up a level at a time until you get

I have a V3 ubitx. I have added the I.F (45Mhz) 50Mhz buffer board (https://ubitx.net/2018/07/21/full-sdr-receive-with-g4hup-buffer-amp/) and taken this to an SDRplay RSP1A. I have added a USB hub and

A few months ago I tested a nice 10.7 Mhz crystal filter I bought years ago. Most likely I did damage it with a 7dbm dds, but I cannot remember exactly. Testing using an attenuator and Antuino in SNA

The height is probably fine.? Is your antenna working, probably not well. I am using an efhw that is 10' high at one end and 20' at the other end. I have made phone contacts into eastern europe on my

I use the HF Signals direction: https://www.hfsignals.com/index.php/ubitx-tuneup/ Requires an amp meter in the power to the finals, or just look for a difference of 100 ma for each setting. 73 Evan

Rubens, Most likely it was heat that fried your finals.? Digital modes have been reported to have this issue on all of the uBiTx models, as they keep the transmitter on for 15 seconds at a time at

ALL I have uBITX v4 and use it only for FT8 in 40m, but the IRF510 outputs are burned, I am changing them, how do I check if the bias and power settings are correct? a) I check the tension in the GATE

Russ, if you have rig based CAT controlling the PPT and freq change function, and it appears you do, then you are good to go. Using a cheap external USB sound card dongle may be better...but...I have

Thanks for the replies! It sounds like my first thing to do is to get it up higher. My best option will be from the top of my roof. Does anyone have success with putting this an antenna right on or

Hi Group I have an Ubitx V.5 working well. One problem I found is that when I connect an USB cable to my Ubitx from the computer for CAT control, my receive level noise increases substantially. I have

I’m starting fresh with a blank PCB board. 72 Aaron K5ATG K5ATG Blog Sent: Tuesday, April 7, 2020 10:45 AM To: [email protected] Subject: Re: [BITX20] BITX 14MHz Build #bitx20 If you are not using a

Belthur, Reading between the lines of your post I will assume that you are operating SSB below 10 MHz, lower sideband (LSB), on a v6 uBiTx. The issue that is reported to you is that your output signal

There seem to be many Raduino PCB patterns in the files section here. 73, Mark

Hi Aaron, I not used MeSquares, but have done quite a bit of "dead bug" construction (which is just placing parts - upside down or not - over an unetched PCB).? Basically I just follow the schematic

Tom -- many uBITXers have faced the same issue...digital modes...long duty cycle...heat... My approach was to hacksaw larger heatsinks from an old Pentium computer motherboard's CPU.? They have a lot

W2AEW (Alan Wolke) has a great video on the layout of Manhattan style PCB building. This one illustrates the island method, but the techniques can be used for Manhattan.

Jim, any chance you could share the PCB file with the group? At least that would be a starting point for those who would like the older Raduino? -- Jason Pirok W4UNX
