Mike, I just took a listen on 7.120, quiet as a mouse, in fact I haven’t noticed any birdies. Joel N6ALT

Mike, I would suggest that You first try the opriginal i.e. Raduino to see where the birdies come from and then start experimenting. Henning DK5LV -----Ursprüngliche Mitteilung----- Von: Michael

To send CW, we unbalance the first diode ring mixer by injecting current from Raduino pin CW-KEY through R104. So all you need do is remove R104.? Can also remove the nearby C1 and R105. Here's the

Got volume control hooked up this morning.? Used RG174 to top of the pot and wiper. With a couple of feet of wire for an ant.? I fired it up. I get lots of "Birdies" singing everywhere.? I can

The uBITX got here this morning at 10am local time. It was worth the DHL trackable shipment to see it go from Hyderabad to Bangalore, over to Leipzig, Germany (dear to lovers of J.S. Bach!), then to

Hi Cor, I too am building a general coverage receiver based on the uBitx minus the transmitter sections.? I have attached a pic of the schematic with circles drawn around the sections

She was nominated by her teacher (because she's a ham) to be part of her school's first ever robotics club and she was accepted. So, trouble shooting and fretting over something electronic isn't odd

Peter,? GPS frequency discipline, time, and Maidenhead grid square has already been done for the Radino/BITX40. The sketch is located in the groups file section. Do a search on

Designing and building a crystal filter with a particular bandwidth from a collection of crystals nominally of the same frequency is an art in itself. For best performance, the individual crystals

By design, in part.? The caps and termination impedance play a part. But also, the bandwidth of a crystal filter should be proportional to the frequency at which it is used. So a crystal filter at

?That's ham radio!!! We are building a stock of people with very unique skills in both radio circuity, antennas, communications, strategies --- who can serve as a reservoir to assist the nation in a

I'll do the sketch when I get off work. I do realize there may be bad things on the board....and I will run through the video, but tonight I will focus on the one bad thing we've already found. I'll

The thing is, we ARE getting a peep out of it, but only at 25 mhz so we are trying to figure out why that is. The other hardware doesn't matter in this instance because I have disconnected the raduino

"Ok, lets try this. Load Gordon's 25 MHz sketch. Find the signal on the HF rig. Edit the sketch to change the freq from 25 MHz to 26 MHz and upload. Is the signal still at 25 MHz or is it now at 26

Hi Allard, if I switch on ?= RADUINO V2.02. and Touch keyer OFF even I touch the two capacitiv sensors.

Loading sketch after sketch hoping to get a peep out of the thing is a waste of time. If one doesn't work, none will. Go back to the troubleshooting video and work your way through the hardware to

No worries,? Vince. Yes...only thing connected is the usb

"Yes...I did this AFTER I reported here. So, it worked the night before last, Farhan's sketch failed, Gordon's sketch failed, then I retried the 25Mhz sketch and it worked again. Note that I loaded
