Goran, Thank you !! 73, Dale K9NN Sent: Tuesday, October 03, 2017 7:46 PM To: [email protected] Subject: Re: [BITX20] BITx40 Block Diagram ? Last spring I did the same for the DX section of VE6AO.

sorry should be line 1831, not 1838

Hi Brent, OK, now I understand. In v1.24, at line 1838: knob = knob * 10000L / 10230L; // scale the knob range down to 0-10,000 change to: knob = knob * 10001L / 10230L; // scale the knob range down

Hi Allard Sorry for the confusion. What I mean is that there seems to be some resistance left in the pot when you reach the stop at the upper frequency end, so the voltage on the wiper of the pot

Last spring I did the same for the DX section of VE6AO. Created a block diagram in Visio. Here's the picture: Hope this helps. 73, Goran VE6GPO

Mike: 36 hours is pretty good!! Also, you wouldn't have stuck with it that long if you weren't getting some kind of fun out of it. What's the flicker from? Is it when you update the screen? If so,

Sorry, don't understand the 300 Hz at the upper end. Perhaps you mean 7300 kHz? You said you set the pot-span to 100 kHz. But to what values did you set the min and max frequeny to? If they are stil

Hi Mike. What I posted was mainly supposed to be an example of what could be done. It is part of a larger work in progress, a home sprinkler system built on a Raspberry Pi 3. (It evolved from an

Dollar to a donut that it's because the setCursor() function has the X coordinate wrong. Look in loop() where the display is updates and mess around with the X coordinate. What it is doing is printing

One slight not-so-obvious advantage of this scheme: ? ? Shorting that keyer paddle to case ground with your body would count as key-down. Could well be not-so-obvious advantages to using Allard's

Jack, found some time to get the code snipet in place compiled without errors however, same result. for every two clicks, the digits move. same thing with the sw1-SW3 buttons. two clicks changes the

John, just wire in the ports you need. No sense building all 8 if you only need three or four antennas mike, wb8vge

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
