My encoder won’t change frequency except by 50hz. Pressing the encoder cycles from 40m on the bottom line to adding “band select?” on the top and then “press to confirm” and then back to the first scr

There have been a few threads discussing how the uBitx has spurs that may exceed the spur amplitude allowed by law. Ham radio is regulated by Part 97 of the FCC regulations. The allowed spur amplitude

Ian (and the group) In great anticipation of running the Nextion display on my uBitx, I purchased a 2.8”display on ebay and it arrived today. I ordered the “Enhanced” version and I found a lithium bat

I find the CW sidetone on my uBitX V3 to be annoyingly loud. Any suggestions on how to quiet it down? I'm running Ian's 1.08 firmware. Thanks... Mark AA7TA

Seems to me you could DIY something better than those $60 Chinese special microscopes with a raspberry pi and a camera. While this isn't exactly how I was thinking it is a good write up http://www.ins

HEEELLLPPP I assembled a Ver.3 board and everything went very well but when I measured the power out it was dead. I don't have the best power meter. I was using MFJ tuner/watt meter, set to 35 watt sc

Howard (WB2VXW) called this morning and we went thru quite a bit of testing and things were not added up, until I mentioned that I had replaced the heatsink, made sure it was isolated from ground but

I was very excited to get my kit - I am pretty novice, but have a firm grasp of basic electronic theory - I followed the direction from HF Signals, and had it up and running pretty quickly, its mounte

Arv: All tough questions, but worth answering. Think of the possibilities. Personally, I think this should be of the free-to-use license, mainly because I don't want to see extensions to the bus that

All: Some here were looking for a good scope at a reasonable price. The Hantek 200MHz, 2 channel is on sale for $271.20. I have this scope an like it a lot. https://www.circuitspecialists.com/digital-

While attempting to get digital working on my µBitx, I had the plugs from the Easy Digi mislabeled. The line from the computer audio out was plugged into my speaker jack. I discovered my error and swa

How much power could handle the Bandpass filters by QRP Labs? Could they be used just adding them in line between the Ubitx and the antenna to attenuate the TX spurs on 15m and 12m?

I have a new tested uBitX transceiver of the pre built type. Will it have a voltage protection for this IC included or do I have to add one? Many thanks, John vo1jcc.

just for tune entenna with a padle is not possibble, and use microphone is not easy, is there a solution? thank for answer

I'm having display issues when I transmit, but only in CW. My parallel 4x20 display begins displaying odd characters and symbols. It also can cause my display to blank when I try to access the menu fu

Just finished assembling my BitX40. On the parts list showing what is in the box, there is item 16 (obviously added on) which is an smd 0.1mfd capacitor. The capacitor is included in the parts supplie

I want to make a substitute Raduino using a "Blue Pill" STM32F103 board. Does anyone know where I can get a quick start on the CAD by finding an Eagle or KiCAD file set that already has the critical c

I've installed the KD8CEC's v1.080 and it works well. Only the bad thing is that I have an unnecessary indication on 40m band. I have S5 to S7 even when I disconnected the antenna from uBitx. It occur

Hi, I travel a great deal, and always take the radio. I’m away from the ubitx at the moment, and can’t measure it. I’ve had an idea for a “tablet-like” rig using the Nextion display to make this suitc

I'd like to build a uBitx completely from scratch. I've been looking at the circuit diagram and I cant figure out how to wire up the raduino. How would one make a raduino from scratch and wire it to a
