Alan, PTT goes to pin 26. As of now the cw is not included. The external switches are not needed as all the functions are handled by touch. Even frequency can be adjusted by touch only. Encoder has a

Bob is right. There is some experimentation needed to use larger display. I have not tried any larger ones yet. My main concern was cost, so never looked at larger displays. 73s SP Bhatnagar Vu2spf

Dear All uBitxers, A new version of software for low cost mcufriend TFT with Touchscreen based VFO + BFOs is out now along with an illustrated manual. This version (3.1cU) provides a row at the bottom

Attached please find the announcement from wsjtx group by Joe Taylor. Please find the mention about ubitx connectivity with wsjtx. I think now the Raduino as well as other versions will be able to con

Wonderful work OM Mike. We all appreciate your efforts in real ham spirit. If I find anything interesting I will point it out for you. Thank you for your great work on consolidating knowledge from var

There is a also design of BPF with lower losses. Have a look at http://www.wa0itp.com/bpf_bandpass_filters.html Happy bitxing Bhatnagar VU2SPF

I have put the details of my TFT VFO + BFO on blog and github. It is a design where standard arduino Mega 2560 is used. The 2.4 inch TFT sits right on top and a specially designed board for Si5351 etc

Please have a look at my blog for TFT touch screen based vfo and bfo. The first version of code should be there soon. Blog is at vu2spf.blogspot.com 73 Vu2spf Bhatnagar

I have put preliminary information on my cheap Mcufriend 2.4" TFT based VFO/BFO with touch controls at vu2spf.blogspot.com More pictures and program to follow. Soon I will be uploading its video too.

In case a toroid is broken and there is no substitute of similar type available, one can replace it with air coil. Online calculators like coil32 provide easy calculations of dia and turns. Use any in

Friends of hamdom, I think bitx is a tool for self enjoyment in radio. All bitxers learned a lot from it. We all have clear understanding that if it doesn't work on arrival its perhaps good for us pro

I programmed a si5351and ardu based vfo + bfo where bfo is also adjustable (a real useful feature to use same box on different rigs). Details are on vu2spf.blogspot.in There are two versions choose de

Satishji on github use download link on right hand side and save. Extract the files from zipped file and there you will find all arduino sketches, a manual , circuit diagram and pcb etch pattern. If y

Hi Ken/M0KOH, Thanks. I developed it to work with my different home-brewed rigs as one common VFO/BFO. Each rig has unique BFO/IF offsets and by allocating group of channels to different rigs it makes

No Venki I do not have a kit but with PCB pattern and circuit diagram you should be able to make one. 73's VU2SPF/Bhatnagar

An improved version of 5351 based VFO/BFO for radio Improving upon the previous design a new version is ready. Features - Rotary dial and keypad for ease of operation - 4 line display - 4 VFOs for qui

Not observed in bitx. Never measured it. Since I did not know about the problem I tried and it worked well. Mixers operate better due to square outputs. Even at low volumes of lm386 audio starts satur

I have been using 5351 for vfo and bfo in bitx on 20 and 40 m. Absolute pleasure to operate. Specially the bfo tuning is very useful as bandwidth of xtal filters may be a bit variable. Check it out on
