The arduino nano board is very limited and memory is about maxed out. I’m working on porting the firmware to Teensy which has much greater capability. I also plan on incorporating WEPR mode using

is there a mod for cw that goes with the w8tee bitx40 tft vfo board ? we are trying to do as many mods on a bitx40 we can but I need listings for all the mods

who was it that made the replacement vfo for the bitx40 ? I wanteed to see the other vfo he was working on

Any rf decoupling at mic input and amp output?

Many years ago I built the BITX40 kit.?? It was the one with the red LED display.?? I am now waiting for my uBITX to be shipped.?? I built a SMM2167 microphone amplifier/compressor on my own

Ron I agree with all the previous comments about your wiring, it does need sorting. Looking at your photographs I think your speaker impedance is 4 ohm, the one I have looks the same type but is

Ron, Unsolder your speaker leads, twist them tightly together and resolder them to the speaker. See if that helps. Try a .01pf capacitor between the solder lugs on the speaker. See if that

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

I believe I found the answer in my youtube comment. It looks like you are building a bitx20a from scratch. A good place to look to answer your questions is

Exactly which version of the bitx do you have? bitx version 3 from Sunil? If so, here's a place to start. http://golddredgervideo.com/kc0wox/bitxver3/bitx20version3.htm Leonard

While I agree somewhat I am not in favor of an automatic antenna tuner because if your wire (especially with a new antenna or experimental antennas) and supporting arrangement leave you without a

The LDG Z-100Plus tunes with only 100mW of power.? It holds eight AA batteries internally, making it ideal for portable QRP operation.? Small, light weight and self-powered. Bert N8NN

I use my LDG Z-11ProII with an end fed wire and my Bitx40. The tuner only requires 100mW of signal to auto tune.? http://www.ldgelectronics.com/c/252/products/21/9/1?(

hi i have finished boxing up my ubitx and all working ok,not sure on michrophone as i have to shout into electret to get any power out,would it be ok to fit 5 volt regulator to supply power to normal

I have built the Bitx20 for the best part, only the final stage with IRF510 remains. Before I start building the final I would like to check if everything works fine sofar. The reception is great but

I fear the coupling is thro power line. Please try star mode power line distribution.if possible have a Inductor based "pi" filter for the independent stages in power feed. Regards MVS Sarma

I see that you have enclosed wiring in a tubing, did you twist the wires before sliding into the tubing. It seems that if you don't twist the wires or replace with shielded wiring there is a lot of
