How likely is this to happen? Bitx40 connected to 40M resonant antenna perpendicular to another antenna with a 100W transceiver running a Winlink gateway. I fully expect front-end overload and nasty n

Is there anyone in Maine, USA that would be interested in a couple unassembled BITX40s? I have two kits. I was about to assemble but have decided not to. I'll make a local person a really good deal. D

Good morning This bitx40 has never worked! You can see from the video, just noise! I found a bitx40 card in a used market and I tried to replace it but nothing changed! He receives nothing except nois

hi! I'm poking at my ubitx 3.0. It hasn't behaved well at all on either transmit or receive. It turns out it was very not calibrated and balanced for transmit, so I've fixed that. However, receive is

Can someone help me with the part number and supplier ( UK ) for the 680nH smd inductors used to replace L5 and L7. Just found some on Digikey but they were very small (0603) and they wanted £12 for s

peeps, i am thinking of a graphics display for the bitx radios. here is the shopping list of ideas: 1, Ubiquitous : We should be able to source it from multiple sources and multiple countries with eas

I hope, someone can help with advice When i want to send and receive SSB at for example 3,701.000 Mhz, I have to set the display at 3,700.300 MHz, 700 Hz lower. At 40 meters, the difference is about 1

Got it done in 24 hours! Hope the prop holds out and will see if the sunday qso/net is still around! -- David N8DAH Kit-Projects.com Shop is open!

I looked at the schematic for Sweeperino. When I go look at Mouser, the SI 517 is only for 3.3V. And it starts at 10 MHz. There is a 514? Goes down to 100Khz. I wonder if the Library works with that o

Finally got around to putting my ubitx into a box, and I'm having trouble getting measurable output. I followed the bias tuneup procedure but when I got to the part where you HAAALLLLOWW into the mic

Hello everyone. Does anyone have a copy of the http://www.hfsigs.com/bitx_with_raduino.zip ? The link is broken and if I enlarge the picture on the web page enough to read it the words are to blurry t

I've just received 300 of these little beasties, so if anyone in UK wants some I'll be happy to supply. I reckon £1 for 10 including postage should be about right. (PayPal is fine with me). Lets not c

Need help is getting my ubitx v5.1 working. I just finished mounting it on breadboard and powered up. All was good, except frequency display showed a frequency that was almost a kHz higher than a nice

UbitX is now up to Version 5. As I understand it, this version, or the software for it at least, is not backward compatible. A great many V3 and V4 boards are out there and there have been many upgrad

I am a newby here. Just finished assembly. I pushed the encoder to get to menu for setup. PTT does short orange wire to ground, but does nothing further. Nothing changes on display. Operator error, or

Hi, I've found the calculator on toroids.info to be very accurate -- so much that I rarely measure after winding anymore. They quote a quite generous length of wire to use (even considering the 1" lea

Hello all, my first post. I upgraded my uBitx v4 to KD8CEC v1.097 and all seems to be working. I'm totally new to Arduino environment, so I was amazed and pleased that the clear step-by-step instructi

I have completed the uBitx and calibrated both frequency and BFO. The sensitivity appears OK. However audio has a strange crispy / semi-distorted sound to it. I read the post from W3JDR https://w3jdr.
