Then board seems alright. It looks like some raduino wire is grounded that shouldnt be grounded. Check your wiring carefully against the wiring diagram at HF Signals. - f

What you are missing are some resistors plus these comments from the Raduino source code file? ubitx_keyer.ino: * CW Keyer ?* ?* The CW keyer handles either a straight key or an iambic / paddle

Yup, that would work. I'm thinking of something useful for detecting low level RF when trying to figure out why the transmitter is putting out 1 Watt instead of 5Watts. But the scaling resistors in

I made a mag loop for 40 and am working on the homemade capacitors remote tuning mechanism. I started with an arduino and servo, and now going KISS with a DC 0.6 RPM motor, momentary rocker switch,

By the way, thanks Doug for taking the time to post your work on doing this. I'll very interested in doing the same thing! Roy WA0YMH

I followed a similar approach.? Mounted a 4 port usb hub inside the case.? One port for the radiuno, one for a 6 buck usb sound dongle, two free for future use (rtl dongle for panadapter and maybe a

How can the plugged in paddle work when only the tip (or ring) and ground of course,are connected?? Don't both tip and ring have to be wired?? What am I missing?

Jerry,??#49555 ( /g/BITX20/message/49555 )

I just posted how I did it.? There are many other ways but this should get you started.?/g/BITX20/message/49561 -- www.bitxmap.com ( http://www.bitxmap.com )

It seems almost every day (or hour) someone has a question about connecting their radio for digital modes.? Following are my cobbled together notes that if the group deems worthy could be the start

The diode detector could be dead-bugged. Better might be pads for an AD8307 on one of those boards someday.

Would someone point me to where I can learn how to use the radio with FT8.

Kees, A couple more things that might fit into that shipping envelope: ? ? Four of Mouser's? ?283-200-RC? for a dummy load? (these are 3W 200 ohms, under a dime each) ? ? A schottky diode plus

Gordon, Small Loops. That is not entirely true.? There are a number of loop characteristics that contribute to the low noise as they very often have a higher signal to noise.? The biggest factor is

Don't know if this will help but when I assembled my unit I accidently staggered the display pins. I only found this out when I assembled a case for it and my mounting holes were off. Another area is

OK, so we won't use the 3 digit display for any indication because of the hassle of shielding it and we don't want extra noise generated if we can help it. We did shield one and the noise drop was

" For the lower bands 160-40 unless huge they are chronically inefficient. They work as well as a loaded 8ft mobile whip but are self contained not requiring radials. " Allison, thank you for putting

Greeting, If I may I have a few questions about my Bitx40.? My display will only on power up will show "Raduino v1.01 and will stop there.? I have checked the purple wire going to the center wiper

Jerry, The more you stock and hold for sale the more costs. Holding material aka stock is sunk money and the cost?is sufficient to mount up fast.? Better to build one or a few things and do it

Hello all, I'm a new member of this group. My uBITx was ordered early feb., sent early march and arrived early may in YO. Due to the "care" taken by the Romanian post, no information about the arrival
