Jerry, Back on topic. Do you know if the Nano will support a SPI interface ? Web info seems to be somewhat ambiguous. That seems to be the requirement of various small TFT displays.....and like you

Apologies if this has been answered before, but I can't find it anywhere. I know the max recommended supply voltage is 15v. But, what is the minimum recommended? I have a 9.9v lithium pack I was

Hi Bruce, have you tried using the standard 16 by 2 display usd with the uBITx in it's custom character mode? from what I recall you can load a number of bytes into the display to set the bits for

Morse code Trainer?? Do you have a link? Jack, W8TEE

I've added some pics in the Pictures section of my project in hopes of helping. 1. I used one of the white protoboards and jumpers so I could easily switch from the original display to the nice TFT

Ordered my ?Bitx on 3/29, notified by Paypal on 4/24, and arrived today 4/25 via DHL. Free DHL shipping thanks?Ashhar.

If you’re talking about the DDS Type I to Type II adapters, yes I have a few (120). I still need to trim one edge off them so they will fit in the W8TEE-K2ZIA Antenna analyzer or VFO. Cost is

KD8CEC firmware 1.072 and later has general coverage/ham bands option. See the manual Rod KM6SN

Using the ubitx with a linear amplifier really needs to see the ubits operating at no more than 5 watts output because of 3rd Order IMD products. Operation at 1 watt would be even better. ALC really

Ebay has a number of kits with the blue pill and an ST2-Link for programming. Do you know if that will work with the download software you mention? tim ab0wr "Giuseppe Callipo via Groups.Io"

I tried my D104 with my ubitx and got 50 milliwatts output while whistling into the mic. The mic input impedance of the ubitx is much too low to work with the D104. You and I both will have to build

Kees, I agree.? For most of us, it's best to continue using the existing uBitx Raduino connector. So create a new Raduino with additional capabilities, as some have already done. By going to an I2C

Thanks, Ian, as soon as possible I'll designs a better schematics and support notes. Bye, ik8yfw.

Giuseppe I recommend your pretty project. Even if it is stm32f103, I think it will work well if only FIR or IIR are performed without any operation. Perhaps the clarity of the sound quality will

Hi Jerry and Jim, Yes, I have connected the centre pin to the Arduino earth (At a mounting hole) It made no difference. I have already found the Mechatronics item, thank you. I also previously

Here is an SPI interface TFT for $8? ? ebay??0665211861088 73 Kees K5BCQ

I'm using my original Bitx40 Raduino(replaced in my Bitx40 by Mike's RaduinoX) with a modified version of Allard's 1.26 sketch as a 40m VFO for my 4SQRP ZZRX-40 DC receiver(QST June 2016). It works

Jerry, The existing horse (today's mBIT-X) you left the gate on has lots of inertia due to the numbers out there. If we need more I/O, features, I would be inclined to make it where it's readily

The encoder is just a couple switches that short one and/or the other signal pin to the ground pin as you turn the shaft.?? The two signal pins go into Nano digital pins that the Nano can read. The
