I don't quite understand your question. What do you mean by "pre-programmed memories"? 73 Allard PE1NWL

Hello Cesar, which wire did you not connect? You mentioned "i didn't wire was pin15 to that transistor as inam not going to use cw". I guess you mean the TX/RX line as shown in

I like the calculator, i've seen it before but lost it and have been using a software version by KI6GD. I have it bookmarked now, thanks. What I am seeing is a 40M band loop with 90+% efficiency,

The cap would be best made of something you can solder or weld. Same as the actual loop. If you use bare sheet metal and non galvanized bolts and nuts, you could solder it. If you build it, let us

If the efficiency is too low, increase the diameter of the loop or the diameter of the conductor. I am using a 7' square and a 30pf variable cap for 10M. It is made of 3/4" copper. The calculator link

i have added a button for a tunning button after that i got nothing so i thought i'd wire the whole cw wiring I got them all following instructions button still does nothing the only one i didn't wire

I have seen both ways too, but at least one youtuber showed that with the feed loop at the bottom and the tuner cap at the top, the radiated pattern goes up and out mostly at 45 degree angle. I am

Thanks! That calculator like my 2 10' sticks of 3/4'' copper pipe. Only a little copper wasted to get the Cap in there. I have most the fittings. I read you can put the control wires inside! Sure why

Conditions were not the best so I waited for the ionosphere to thicken ( during and after twilight ) and made these contacts..... S / R VE3THR- 33 33 KA9OOI- 57 55 AA4PG- 55 55 N2CQR (100W BITX)- 57

Here are a couple of pdf articles that might help. Marco - KG5PRT

Take a look at the "midnight loop" project (pdf at https://www.nonstopsystems.com/radio/pdf-ant/antenna-article-magloop-midnite.pdf (

I have never heard an outside signal on my bit40. Testing with a signal generator I get signals down to or below 10uV? I have no antenna, but a wire out the door brings in nothing but a little more

I use 1.75mm Filament. I use Simplify3D set to 30% fill and 0.1mm layer. I have setup in Inches, I can see relative size when the part loads. The big knob loads with the bottom (hollow parts up), so I

Is there any plans to make pre-programmed memories?
