The LM386 will be putting out well under 1 Watt at max volume. Generally speaking, a bigger speaker will be more efficient and sound better. The acoustics of the enclosure can make a big difference

So just a resistor between the wire and the middle leg of the volume control? Ok....that won't be hard. I have a couple of 1k ohm resistors left over from building that dummy load. I've noticed the

John W5NNH Some of us have already been discussing this off-net. It seems possible to do direct hamlib-to-BITX code, but having an abstraction layer between probably makes things more flexible.

Have others tried the original uBitx audio AGC circuit? Looks like it would be simple to add on a small perf board with selectable FAST/SLOW front panel switch using different values for C70 /

1st off I want to wish everyone a Merry Christmas or whatever else you celebrate this time of year. I enjoyed talking to many of you on the BITX40 nets. We have been doing just over a year now. So

The Heil Traveler was intended to work with the IC-706 and other rigs. Jim's successful use of this headset on the BITX40 suggests that speaker-mic's and other accessories that used the 8-pin RJ-45 on

Have you tried a BCI filter? I built this one to kill a nearby AM station on my Forty-9er (March, 2016, QST): It has a small insertion loss and knocked the slats out of my BCI problems. I used

Dear, My ubitx ordered dated on 19/12 /2017, #BITX-329072 is successful and payment Reference no: 106312672725. By the way any track consigment no, of Indian postel service for

Ashhar has told us he is updating the hgsignals.com website so you can order the raduino separately again.? The nano has always been soldered to the board.

Yeah!? That would be really nice if I could order a complete spare raduino (minus the display would be okay as I have a number of them on hand).? That would allow experimenting with the code safely

I must have been wrong, Thank you Jerry. I thought, when I updated the firmware on my Bitx40 I only brought the Nano upstairs to my computer. Well, I still would like to understand or order another

It always has been, mine was built a year ago and came soldered down. Could be argued that it is more reliable that way.

Without a BPF, there could be unexpected mixer products below 80m that the LPF would not take out.

I would like to know how to order an extra Raduino board with Si5351, Arduino Nano. Fully tested for a back-up on my uBitx. Now that the Arduino Nano is soldered to the expansion/connection board.

Hi, How can I order a ubitx raduino?? Thanks, Rod KM6SN

Thanks very much for those corrections Jerry! When on 80, I use a very nice 80 m lpf on output. I had some dyslexia with that integrated circuit number. Sent from my iPhone

You're very welcome for the appreciation! Gives a warm feeling. Squeals are a common thing from that audio amplifier..... Try putting a 1000 ohm resistor in series with the wire to the middle leg of

Seems you all had a long night. My inbox was fully loaded with messages on your journey to success. And what a journey it was. A job well done ! Enjoy your new radio and have fun with it. Merry

To be fair, they suggested it as well. I was so overwhelmed with this that I didn't heed it. I was stressed and thought I had gotten in over my head...was afraid to do anything.? They were working
