Lots of kits. I have a LPF board kit and the Desna transceiver kit. I got the LPF board for the ubitx. https://www.rv3yf.store/ Mike AI4NS

There are several different versions depending on the display(s) you're using. Be sure you're trying to load the correct version. If you're loading a .hex file, I believe you want

Yes, but how do you but the Bluetooth module to sleep when the USB cable *is* connected? Perhaps you can power the BT module from 328 pin and dont set it high until it's done so in setup (). The

All: I know a number of you read Al's and my article in the November, 2018, issue of QST and were kind enough to vote for it:

By "current SERIAL output of the Arduino", I assume Mike means the D0,D1 pins for the ATMega328's UART pins. D0 is a UART RX line into the ATMega328P, D1 is a UART RX line out of the ATMega328P, both

The version you load should end in “P” Art

Every time I run into resistors with ambiguous color codes I grab the DVM first thing to check them. Clark Martin KK6ISP

Remi,? I'll try out the CEC firmware. It looks like it should work with the stock display, correct? I have not explored the alternate firmware, I've only seen it used with the larger touchscreen

Thanks Evan and Thanks to Remi.? your info got it working.? The original software I downloaded had nextion selected? so commented that out and uncommented the original lcd.? Works nice.? Now on

the 47 ohms resistors provide a resistive source impedance of appoximately 50 ohms. the emitter follower biased at 7 ma has an Re of 26/7 ~3 ohms. this 3 ohms and 47 os together provide a driving

Yes, the HC-06 lil' module, would be wired in where the current SERIAL output of the Arduino goes. (I've not yet done CAT, but I'm presuming this is your 'CAT' Serial). You'll have to research the

Be sure you have the correct file for the display you are using. For the original display the .hex file is ***16P.hex, where the *** is replaced by the rest of the file/version name. Key is P for

ubitx.h, line 27... uncomment it and comment nextion display. (default) I just do the upgrade, only this thing to do. //==============================================================================

Just picked up a completed ubitx v3 from friend who no longer wanted to fuss with it.? Am having difficulty installing the KD8CEC arduino program.? The rig comes with the original 2 line lcd.? I

What is the purpose of the 47ohm resistors like R27 at the output of each rx and tx amplifiers? Are they really needed?

*I work too with this problem, using stock firmware I don't have these tone, but upgrading to KD8CEC firmware, high frequency audio tone appear, louder that all voice band and give me headaches. I

I put the 45mhz crystal filter with input and output 2:7--7:2 binocular transformers that Raj/ Warren first came up with and others added cap in the place of R27. Used the small board from Nick for
