The uBITX is 10 dollars cheaper (after 12/25) works 80-10 M, does SSB in addition to CW, and is a Superhet to boot!. The µBitx is a HF (3-30MHz) all-band SSB and CW transceiver kit. All AGC's from this point on will include a 10ohm resistor for V4 and V6 mods. Recommend using a separate 5v source so as not to over heat. Replacing those relays brought the uBITX into compliance for even and odd order harmonics across all band for CW and SSB modes. QRO (24v) mod. One of the challenges with the µBITx transceiver is that there is a very active community of fixers and modders. What he found is that RF input signals greater than S9+5dB (-68 dBm) become distorted due to the audio output clipping on the negative side. I have the radio ready for testing will it work? or have I mixed up the ribbon cables:-) Thanks for dropping by, Im building the. Need information about the previous version of uBITX?

Just a quick response to show how easy it is to install the Nextion screen 4 wire cable comes with the display Red 5+ volt , Gnd. This is a software-only mod that improves the responsiveness of the encoder wheel. After three days of operation on 40 Meters it was clear the uBitx needed some shoes. The power connector has 3 leads (Ground, Radio, and PA) to facilitate this mod. The Full uBITX Kit including the the box Small is QRP It is a small 6-1/2. Anything else I can think of? Eventually I'll put it in an enclosure once I figure out which these mods. What he found is that RF input signals greater than S9+5dB (-68 dBm) become distorted due to the audio output clipping on the negative side. Bigger prettier screen (I2C) Switched 2M transverter. I will keep you posted on what I learn about amateur radio on this blog. The V2 code allows you to do more stuff, such as adjust the BFO frequency to better align with your crystal filter. TRANSISTOR DAMAGE ON BITX40 and UBITX-----BITX40 Q13 OVER DISSIPATION WITH HIGHER BOARD VOLTAGE-----CREDIT TO JERRY GAFFKE: Correction: The 150mW max dissipation. Release I2C Type Signal Meter firmware V0. This transceiver is Farhan' s uBitx mod - 10 watts, easy to build, general coverage SSB/CW transceiver for HF bands. It is able to deliver 2 x 2. Having ordered a uBITX and await it's delivery sometime in the new year, I'm wondering what our most learned would consider 'sensible' mod(s) to enhance the uBITX, or should I just use it 'as is' ? In the first instance, I will get it up and running as supplied before undertaking any mods so as to establish a base line to work from. Calibration is a 2-step procedure that involves accessing the 'Preferences' menu and setting the BFO so that noise from the speaker falls within parameters described here. The transceiver automatically selects the proper sideband for you (you can. In order to install as suggested by the folks at uBitX I had to scrape some traces and fold out the inductor leads. : One annoying thing about BITX I felt is relay clicks and clicks caused by relay K2 in audio line. The purchaser needs to assemble the board into an enclosure and wire up sockets, encoder and potentiometer and provide a power supply in order to get the transceiver working. See full list on ubitx. Many of the BiTx40 mods being discussed are directly applicable to other similar QRP rigs. Ian KD8CEC is working on a new release of his CEC firmware for the uBITx that will be more modular in approach (picking up on John VK2ETA’s mods to Ian’s firmware), interface with a range of displays (I2C versions of the 1602 and 2004 displays as well as the display that comes with the Raduino). After three days of operation on 40 Meters it was clear the uBitx needed some shoes. 200 for uBITX All Version (include v2, v3, v4, v5) I did the firmware work for v5 when uBITX V5 was released, but I release it now. So don't be surprised if you make that mod --it will not turn on your big 1. It also tunes like one with a proper encoder for tuning instead of. A number have gotten them on the air. 0 to NANO adapter card was designed to work specifically with the new uBITX Version 6 with the color touch screen.

Requires more mods, including one that drives the BFO from the si5351's clk. The AGC has a S-meter tap as well as a place for RF gain control that can be remote mounted with a 1k pot. The method requires that you use the custom CEC firmware, or modify other firmware, as this appears to change the output frequency at the tap point. The first article deals with buying used and new equipment, while the other article is a review of the uBITX QRP transceiver. It is able to deliver 2 x 2. Al Curtice’s 1957 Willys Truck Resto Mod Project 2 days ago QRPblog. I calibrated my uBITX (v6) today and made my first SSB QSO with the rig. Anything else I can think of?

Consequently I decided to implement solid state circuitry to replace both relays used for TX/RX supply switching and antenna changeover. UbitX ver 4 Audio amlifire and Tx popfix plus S-meter sensor PCB I have ubitX ver3 working well with SSB and Digital mods Just now om Farhan released ver 4 circuit with new transistorised audio amplifire and Tx popfix circuit,and mods in Rf PA, I decided to apply audio amp and popfix mod to my ver 3 pcb,and also want to upgrade software. ND6P came up with this mod after testing his uBITX on the bench to determine how much signal it could handle before distorting at the speaker due to clipping of the audio signal. They are a consequence of the uBitx. To make the necessary connections between Nextion LCD and Raduino TFT board I used a 90 degree male header, pins attached to TFT LCD. To cure all these problems I installed a nextion display with Ian Lee, KD8CEC's Ubitx5 firmware and it worked. The uBITX is a US$129 HF SSB/CW QRP transceiver kit that works from 3 MHz to 30 MHz with up to 10W TX power. If you tap on one of the VFOs, Fast tuning gets enabled where each step of the tuning encoder results in a jump of 50 KHz. The purchaser needs to assemble the board into an enclosure and wire up sockets, encoder and potentiometer and provide a power supply in order to get the transceiver working. This is an update to my previous video. Print Setting: Select Mini Balsas MP: There is no support Resolution: 0,200 mm Filling: 30% Notes: The control panel / speaker is to be printed in three methods, with a manual color change thread, not move. It's a fully analogue radio, but it can be combined with an RTL-SDR to create a panadapter display thanks to a tutorial released by KD8CEC. Pcb is made from CM2KMK 2017 mod version. Introduction. Still need to figure out why I get 2 to 3 watts, not 10+ output. One thing that I neglected to mention was the amount of internet support there is for the uBITX transceiver kit.
