Hi, I ran across this antenna system proposed in those idealistic days of the atomic age. When every home would have a nuclear reactor in the basement to heat their home in the winter. And Las Vegas c

Wanted to share an update with the group as I've made multiple posts over the past year regarding BCI, filters, music, etc. I finally did complete and install a BCI filter. After having the uBITX v6 f

Hi everyone! I did an antenna analyzer with pic18f250, si5351 and sa612(Ne612). I have a hardware problem. It seems to work fine if I test for example with a impedance about 50 ohms. But when I test w

The wire is 66 ft long with a loading coil and a balun. The variable capacitor I have is 10 inches long with 240/31 capacitor. There’s another value on the cap. 154/16 Thanks everyone!! KE7GO Steve Be

#antennas

Steve I use an LC network to load a 55 foot end-fed wire for an original BITX, and for my uBITX. The inductor is a roller coil from an ARC-5 transmitter. This with a Stockton bridge for SWR management

Thanks Scott. The wire is 66 feet with a balun and loading coil at proximal end. The capacitor is 32-241 and is 10 inches long. KE7GO Steve Behlmer

Steve, how long is your antenna, and how many pF is your cap? Scott Ka9p

Hope I’m not duplicating a previous feed. I’m using an end-fed 40-10 antenna. I have a very high voltage variable capacitor that I would like to incorporate for remote tuning. I can create a waterproo

I'm just curious about what everyone uses for an antenna tuner if they even use one. I got one of the N7DDC ATU's did the QRP Mod and it got fried at field day. Since it came with a really nice case I

Frank, There is a low pass filter in the transceiver as shipped from HFSignals. This is set to reject any frequencies above 30MHz, so if it is an FM station, then a high pass BCI filter will not help.

Mark see the attachment, might be the FM Broadcast station near you. If not that one, listen for a while to see what the station ID is. You probably need a broadcast filter. Good luck. Frank KG9H

Mark, My Bad -- Somehow when I re-did the website, the BCB filter got left out. Here's the construction manual for it and I do have some PC boards available. Email me privately and I'll make you a dea

Mark, Check out TSW’s website, www.w0eb.com. Look for and click on the broadcast band filter tab in the top left corner. We have a couple PC boards for through hole and SMD versions of a really simple

Did an alignment using a locally generated signal and a little wire for antenna. Audio sounded fine. Using my outdoor antenna, I'm just getting garbled noise. Can still pick up some music, too. Thinki

#ubitxv6 #antennas

Mark If you haven't performed BFO calibration you won't have a working radio. Whether this 7s the only problem is unknown. A short piece of wire should bring some ham signals on 3.5 or 7 MHz particula

#ubitxv6 #antennas

Mark, There is no short answer. For a uBITX with calibration issues, it could be 10+ miles. For a properly calibrated radio, it should not interfere unless very strong and less than 10 miles.. So the

#ubitxv6 #antennas

Well, this is the only HF receiver I currently have. It is in a metal case. What's considered "close enough" for a MW broadcast station?

#ubitxv6 #antennas

Does It happen with other receivers/trasceivers too? It might be MW transmitter nearby but also a local FM broadcast station. The low pass filter built into the Ubitx removes the FM broadcast of they

Moving the radio to the second floor and using a random wire antenna for receive (indoors), I'm getting nothing, but I'm also not getting the broadcast. Prior to this I've mostly setup outside, but it
