OK, great! One other question...what is the relationship between the "PPM" calibration value and the "CAL VALUE" in line 43? =Vic=

Ah, very nice that you were able to do all of this, and document it so well. See my comments inline with your original text below ?

Not 100% sure but popular thinking indicates the "crystals" on smaller Arduino boards are actually ceramic resonators.? If this is true then it should be possible to use capacitence to pull them

Tilman and all, Per, I think, Raj's suggestion, I change R63 to 11 ohms, and that seems to work well. 0805 parts fit on 1206 pads, and power dissipation is not an issue with an 0805

Thanks for fast ansver, it is working. In next days try to conect to pc. if it working with n1mm. And with mmvari. This program using for digital and for contest. Use this

Not familiar with the ATMega328P, but table 9.3 on p300 of the datasheet says the Low Power Crystal Oscillator can take a crystal anywhere from 0.4mhz to 16mhz, and that we must load bits CLKSEL[3-1]

Please keep in mind that some of us don’t want a disk image and prefer a simple package to install. This way, i can just add it to a disk that is already set up the way I want my Pi to be. Thanks

Jerry My uBITX has proper 10W output on 80 and 40 meters keydown CW. So I assume the BIAS is set ok. When trying to get some serious output power (10W) running phone I have to wistle in my mike a

I am still trying to identify the cause of an audio "squeal" which makes receiver unusable. Audio is ok at lowest volume setting. As I turn up volume, a "squeal" begins and gets louder obliterating

Are T1 and T2 identical in the Bitx40? Any others? I have a spare board and my original board has a mechanically intermittent T2. I am practicing desoldering and removing these devices and will

joe i saw your posted message on my blog. and Thank you very much for youer suggestion. Most of the wsjt-x portable work is done. It was a little late because i had to work with uBITX

Bill Thanks for using this firmware. At first I wanted to make uBITX a real radio, so I started to put only the most basic functions. As I worked on it, I got a lot more fun with the opinions of the

Philip I am going to put uBITX into the case finally this week.Until now it was open for testing. I will cut off the power line of USB like you. And to fix the Arduino Nano reset problem, i will also

Matjaz Thanks for interresting. I saw the schematic you attached. It seems to have only an encoder and a function key. I do not test it, but I guess. so My guess might be wrong. My guess is that

Just a reminder! I'm probably not going to make it on for either session today. The flu shot apparently didn't work! Have fun! -- John - WA2FZW

hello Ian I have problem too use software 0.27 for uBitx. To load in arduino nano use Xloader and your hex file. But when conect power , first have on display mesage about version and then CW

What Cesar has not told us other than he has some great antique guns is that he has 6600 function generator. He also has a pico scope. I've been trouble shooting via whatsapp which is faster than

I know I'm late to this party but you cannot swap crystals on nano board without first using a atmel programmer to burn the fuse bits that tell what freq it will be using or you will brick your

Further tests and head scratching. ? Since I replaced the Arduino and mounted it on female headers I decided to do more tests to try to answer some of the leads and questions in the thread. ? I used

I have no idea what your sets of pins are.? Read this post to understand the relay pin numbering,? and how the rail labeled "TX" gets connected to 12v when you press the PTT switch to transmit.? ?
