Re: BITX 14MHz Build #bitx20
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

One possible substitute for a Spectrum Analyzer's "Tracking Generator" #ubitx
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

Re: uBitx V5 can't make a contact on ft8
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

Re: Heatsink question #v6
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

BITX 14MHz Build #bitx20
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

Re: uBitx V5 can't make a contact on ft8
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

Re: Find an older style Raduino #raduino
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

Re: uBitx V5 can't make a contact on ft8
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

Re: uBitx V5 can't make a contact on ft8
Gavin At that height your radiation will mostly be straight up. The ground connection should matter little for radiation,? its to bleed off static charge to prevent rig damage. I sometimes use an

Re: uBitx V5 can't make a contact on ft8
Gavin, I agree with Scott¡¯s antenna suggestion. Another improvement I discovered was to use a USB dongle sound device (see below, the one I use) The sound volume and quality are greatly improved

Re: #firmware #i2c #smeter #ubitx #calibration #calibration #firmware #i2c #smeter #ubitx
Elecraft has (or used to have) a simple S-meter calibrator that put out a signal that was supposed to be S9 and was pretty inexpensive, if you really need to have accuracy. Then you could check it

Re: uBitx V5 can't make a contact on ft8
Hello Gavin, Certainly you will have a better experience if you can get you antenna up, as high as possible. I am a beginner as well. My antenna performed great when I was able to get it up 50 to 60

Re: Calibration needed ? #calibration #v6
In my experience, you will leak unless you calibrate the BFO to only allow high treble to pass (sound super tinny). The diodes on the mixers just aren't balance well enough to stop the carrier

Calibration needed ? #calibration #v6
Hi Folks, I am using my uBitx with NKK linear. I have reduced the power by using RV1. I have calibrated both BFO and Frequency by watching Mr. Ashaar's video. If I increase the drive to 7-8w to get

Re: Si5351 voltage output #arduino
If you are using a 20MHz oscilloscope for measuring the 40-70MHz square wave, you are more likely seeing the loss in the amplifier gain in the scope than genuine drop in si5351 output. This might be a
