[Update] New All-band SSB/CW Micro BITX Now Available | bitx – POLLICELEE

bitx: นี่คือโพสต์ที่เกี่ยวข้องกับหัวข้อนี้

HFSignals.com now offers the uBITX (micro BITX) HF radio, an all-band QRP rig that operates both sideband and CW, for the truly remarkable price of US$109, postpaid from India. The main board comes assembled and tested. The buyer supplies a chassis and some peripheral parts”

The µBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with up to 10 watts on SSB and CW with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.  The µBITX is a general coverage HF SSB/CW transceiver kit with features you demand for operating ease, convenience and versatility. It features digital tuning, dual VFOs, RIT, CW Keyer and more.

Operating

It is a joy to operate. Press the tuning control to access all the features. Dual VFOs, RIT, CW speed, sideband selection. etc. are all accessible from a single menu. The transceiver automatically selects the proper sideband for you (you can override it, too).

Technical Specifications

The µBITX is an understandable radio and, hence, can also be a learning experience. The complexity is kept to a minimum so you can always repair and make changes if you so desire.

The µBITX has a carefully thought-out operator interface. The tuning knob features many menu options available with a simple push on the tuning knob. From RIT, to dual VFOs, to the keyer, and many other features are all accessible from the tuning knob by simply pushing on it. There are intelligent defaults everywhere (these are easily overridden). Example : below 10 MHz, it auto-selects LSB and vice versa. To operate CW, you just press the morse key.

Architecture The µBITX uses upconversion to the first IF of 45 MHz. This eliminates the need for a large number of band pass filters, keeping the design simple and virtually image free. The roofing filter at 45 MHz is 15 KHz wide. The signal is then down-converted to 12 MHz where a low ripple SSB filter with 8 crystals is used to provide a sparkling audio.

The transmitter has push-pull PA using two IRF510s for a clean output. The low cost IRF510s are simple and inexpensive to replace should the need ever arise.

Receiver :

  • Sensitivity: a 0.2uv signal is clearly audible

  • Selectivity: 2.4 KHz,  low ripple SSB filter with 8 crystals

  • RIT (Receiver Incremental Tuning)

  • Continuous coverage from 500 KHz to 30 MHz

  • Sideband selection

  • Detent-less encoder tuning. Tunes with larger step rates when tuned quickly

Transmitter

  • More than 10 watts up to 10 MHz, 7 watts up to 21 MHz, 2 watts on 28 MHz

  • CW transmit with the built-in keyer

  • Uses IRF510s  x 2 as PA and  2N3904 x 4 drivers in push-pull mode for low distortion transmission.

Raduino Features

The Raduino is a small board with an Si5351 clock generator, an Arduino Nano and a 16×2 LCD display.  It plugs into the main radio board. The software that controls the radio is written in Arduino’s C langauge.

The feature set of the 

µBITX is controlled

 by the Raduino’s Open Source

 software. Open Source allows you to 

further enhance the software if you 

choose to do so.

 The menus are accessible by pushing the button on the tuning encoder. You can add more features by modifying the Open Source code available at

  • Dual VFOs

  • RIT

  • Manual override of LSB/USB selection

  • CW Keyer Speed and tone selection

Can I build it?

Boxing it. You can pack the µBITX in anything from a cookie box to custom-made 19 inch rack. A metal box is highly recommended. We have used it every way including the bareboard on the bench.

Some soldering is required. The kit is easily put-together. You have to mount the board inside an enclosure of your choice, screw in the connectors and solder the wired connectors to the sockets and controls. That’s all. All SMD’s and other components are pre-soldered on the PCB at the factory.

Take a few hours to wire it up.  Preparing the enclosure will take most of your time. You will need basic kit-building tools like soldering iron, a VOM. etc. Set aside a few hours to wire it all up and enjoy the experience.

Support is here. Being an Open Source project, support is provided through a very active builders’ community at http://groups.io/g/bitx20. The collective wisdom of thousands of builders is at your disposal. Ashhar Farhan, the designer of µBITX is very active on the group.

What’s included

  1. A fully test and tuned µBITX HF transceiver board (6″ by 5-1/2″).

  2. The Raduino board with display with µBITX firmware installed.

  3. Detent-free tuning encoder with push button for menu access

  4. 3 audio sockets for the mic, earphones, and keyer

  5. A high quality BNC Antenna connector

  6. Power supply connector and jack

  7. 8 brass standoffs with nuts and bolts for mounting the board(s).

  8. Reverse protection diode, some resistors for CW keyer.

  9. Electret mic and a miniature push button for Push-toTalk

  10. Volume control with on/off switch

You will have to supply your own enclosure, power supply, microphone case, speaker to complete the radio.

[Bytes #1] Part 4 Single Balanced Mixer Build From BITX Schematic


The second mixer is built straight from the BITX schematic. I do a quick walkthrough of the BITX20 schematic, and will revisit it in more detail as I assemble the receive portion of the schematic in the next video.
I show that the mixer is working on the spectrum analyzer after the built. Properties of the mixer will be toyed with in the next part of the series, and I’ll take a look at what tweaking the potentiometer does.
I never get the thumbnail dimensions quite right, do I?
The mixer came together quite uneventfully.
