ALL I have uBITX v4 and use it only for FT8 in 40m, but the IRF510 outputs are burned, I am changing them, how do I check if the bias and power settings are correct? a) I check the tension in the GATE

Russ, if you have rig based CAT controlling the PPT and freq change function, and it appears you do, then you are good to go. Using a cheap external USB sound card dongle may be better...but...I have

Thanks for the replies! It sounds like my first thing to do is to get it up higher. My best option will be from the top of my roof. Does anyone have success with putting this an antenna right on or

Hi Group I have an Ubitx V.5 working well. One problem I found is that when I connect an USB cable to my Ubitx from the computer for CAT control, my receive level noise increases substantially. I have

Belthur, Reading between the lines of your post I will assume that you are operating SSB below 10 MHz, lower sideband (LSB), on a v6 uBiTx. The issue that is reported to you is that your output signal

There seem to be many Raduino PCB patterns in the files section here. 73, Mark

Hi Aaron, I not used MeSquares, but have done quite a bit of "dead bug" construction (which is just placing parts - upside down or not - over an unetched PCB).? Basically I just follow the schematic

Tom -- many uBITXers have faced the same issue...digital modes...long duty cycle...heat... My approach was to hacksaw larger heatsinks from an old Pentium computer motherboard's CPU.? They have a lot

W2AEW (Alan Wolke) has a great video on the layout of Manhattan style PCB building. This one illustrates the island method, but the techniques can be used for Manhattan.

Jim, any chance you could share the PCB file with the group? At least that would be a starting point for those who would like the older Raduino? -- Jason Pirok W4UNX

If you are not using a Bitx pcb, then your question is questionable. Build instructions are for using a bitx pcb. For one-off builds using manattan or ugly method you just need to decide your own

I got an email from a trusted friend this morning with some very interesting information for those who have spectrum analyzers that do not have tracking generators, or the new versions of inexpensive

I'm still waiting for an antenna adapter for my V6 but am interested in setting it up for FT8.? So exactly how did you disconnect the PTT connection on the dongle? I'm not sure how the dpdt switch is

I might mention that if you have some old junk PC power supplies, you can salvage these isolation kits from them.? These supplies have several transistors isolated from their heatsinks.? At 3 bucks

Thanks Jason, but for everyone's info, I do not have any more old style Raduino's around here. Jason got the last one I had, sorry. Jim, W0EB

Hello everyone, I'm going to start building the BITX 14MHz ( https://web.archive.org/web/20181002132459/http://www.phonestack.com/farhan/bitx.html ) build. It's going to be my first homebrew

How has it worked on phone? As a ham we are required to have control of our signals. Owning a radio is a start but you need to have an idea of it's power output Even a simple CB quality SWR/Power

Your best bet is if Jim W0EB (I believe) has any left. I purchased one he had left over, but not sure if he has another. I found something that looks like another original Raduino clone on Ebay, but I

Gavin, I also have the same antenna as you do, mine is about 25’ in the air. I‘M making FT8 QSO’S all over NA and the odd EU as well. I also found an antenna tuner works well with this antenna
