I’ve been able to get good power output but then the power suddenly drops down to 5 or 10% of that. (I used hw_settings.ini to limit the output on 30, 40 and 80 to less than 30 watts at Drive=100.) Th

I am using Inverted V Antenna and getting 2.0 or sometimes 4.0 very high SWR in CW mode, but in SSB mode its 1.0 and 1.1 on 40 Meter Band. If I use my EFHW Antenna on 20 meter, SWR is 1.0 or 1.1. Kind

I have been listening to my uBitx 6 I assembled a while back each day at work and enjoying it lately. It worked well when I first assembled it, but I felt like I needed to mess with the mic some and g

I installed a pair of 1N5349B 12 Volt 5 Watt Zener Diodes, back to back from the Gates of Q18 and Q19 to ground. These diodes should keep the Gates of these two FETs from being damaged by oscillations

Brad - Update on this - I was just in the lab with my sBitx decoding FT8 on 20 meters, and looking at the clock generation circuitry, and I got to a point where I needed to pull up a schematic. My com

Hi!!! Today I soldered an antenna conector at c68 just to see how the rest of the radio works above 30mhz. First with a small signal generator and then with an antenna. The antenna used is just a rota

It used to be that radio problems were found with a voltmeter and tube tester. Now, we are looking at lines of c code, tweaking configuration scripts, and using network protocol analysis tools. Love t

Hi Brad; Open a terminal console window on your Raspberry Pi and type paprefs This command should open a GUI window with PulseAudio Preferences. Select the Multicast/RTP Tab. You should see a check ma

Just checking around with the spectrum analyzer and found some unexpected signals My simple resistive tap off my ancient Heathkit Cantenna dummy load is NOT guaranteed to be flat across frequency, but

So it looks like, not absolutely for sure but looks like the Sbitx has the ability to take out my network. So I'm not a network expert, but been having problem with network speed to the internet and w

Hi I know this is probably premature but does anyone know if there will be a future full kit sbitx like the ubitx6 ? Will assembly be similar to the ubitx6 ie no soldering just installation of parts a

All: I was not sure how accurate the watt meter might be on my recent purchase (ebay 284879283916). Today I went over to Al's who has a top-of-the-line watt meter (Bird). At 10.2W on the Bird meter wa

Hi, I have been experimenting for a while now on a version of the uBitx minus the predriver and trying to roll my own amplifier. At this point I have a uBitx till before the predriver stages. Setup Tw

Wondering if there is a way to create a vhf+ version of the sbitx? I understand that this is mainly designed for hf. Looking for a nice dedicated all inclusive unit for the rover. James W8ISS

Hi Jack, How many different bands did you use to run your test? I have one coming and I will try to evaluate that for myself. 73, Bill KU8H bark less - wag more

Hello, Since I went through this forum, I find an important batch of changes So I have a suggestion, and it’s just an idea. I think it would be wise to make a list of everything that could have been c

I am running the latest version of Wsjtx for Ft8 on Win10 Ubitx V6.1 Clock time spot on I keep checking. Plenty of Ft8 on Waterfall on 20 metres but now no decoding. It was ok previously. Tried as man

Hi to all!! Today I found in the junk box two old boards with two mrf5015. Since I havent received my tx rx switch board and replaced u3 and k9 with normal relay, why not try the mrf5015 and see what

Hi This is a real beginner and basic question: I am interested in building the ubitx 6. I am in the medical field and I am not as confident as some regarding the schematic. I dont want to make it a br

Does anyone have the part number for the AXICOM relays used to replace the original relays in the uBITX v4 to improve crosstalk? Thanks, Mike N2MS
