I received a 10 turn pot today, installed and changed the sketch for a 300 kHz span. It works great, however I found the tuning a bit too coarse. I changed the span to 100 khz, tuning was much better,

Really a nice job. I'd be interested in seeing the schematic. I've been thinking of a remote antenna switch, but I don't need 8?ports! ? -- John - WA2FZW

Mark: Where is the display_fields[field].width object defined? I don't seem to have the source code. Jack, W8TEE To: [email protected] Sent: Tuesday, October 3, 2017 3:03 PM Subject: Re: [BITX20] A bit

I don't know where this code came from, but display_fields[] is an array of objects, but I don't know what. Who has the complete code? Jack, W8TEE To: [email protected] Sent: Tuesday, October 3, 2017

I am trying to make a complete program with setup() and a loop() with your code. I think it would be real useful. I am stuck here, what is display_fields a function somewhere? Compiler was asking, and

I uploaded Version 1.1 of the software in the A 40 meter magnetic loop antenna ( /g/BITX20/files/A%2040%20meter%20magnetic%20loop%20antenna ) folder. It fixes a bug in the LCD_Print

Not obvious the third pin is required for the capacitive touch keyer. The dit and dah Nano input pins could also have open-drain outputs, so drive the pin low and then release it to slowly float back

Thanks for noticing the bug! The code snippet is out of the mag loop controller code ( /g/BITX20/files/A%2040%20meter%20magnetic%20loop%20antenna ) . It's only using about 30% of the

Another way to minimize LCD activity is to only display the text "delta". The following function is one I created to display text on an LCD. The display being "broken" into a number of "fields" (row,

After endless hours and more diet coke that should be allowed by law, I got the RTC to display on the LCD along with the antenna port. I have this grandiose idea of when the switch is off (But power

Right now, I'm not sure. If there is enough interest, I'd do a short run of 50 or so. I'm thinking about $20ish a pop The photo is deceptive, the board is about 9" square. Double sided, plated through

John, I designed the board and laid it out using diptrace. I had a few made. They are expensive, because of the size of the board. The photo is deceptive as it's about 9" square. Here is a close up of

Yeah, and/or: static char oldrig[21]; since strcpy won't malloc any space for you. I actually intended it to be that way but forgot the [21]. I also changed it all 3 or 4 times before I sent it.

John: There's a subtle bug in your code that could cause problems. In the for loop, the second expression: ??? for ( i = Buffer_Length; i <= LCD_Width; i++ )????? // Yep! puts a space where

And where do you get it? ? -- John - WA2FZW

In addition to what Jack said about not re-writing something that is already on the display, instead of clearing the display (or just a single line) before writing, I just pad the string to be written

Hello Yep, I looked at the circuit and the Hendricks kit already has pads for the DDS. The key question is what can we leave leave out of the board ? I have not built the board yet. The VFO seems

To cure the flicker, store what you already wrote to the display (eg. rig). If it's the same as it was, don't rewrite it. void printrig(char *rig) { static oldrig; if(!strcmp(rig,oldrig)) return; else
