Interesting ubitx can receive FM ?? Could use better headphones though still would expect the sound quality to better.? Powerful signals like my nearby commercial radio come in a lot better,

Hi guys, I've owned an RF Explorer for almost 2 years. It's an excellent instrument (and low cost <$200). It does take a little getting used to the menus and setups. But if you connect it to a PC the

THANKS Gary and Ken! I don't know how I missed the front panel board in my search of Sunil's www page - the product description explained how the early cases didn't include the board. I ordered the

I bought one right after I bought my uBitx in September of last year. Was a learning curve to understand the use of the instrument, from the standpoint of setting the center and span to capture the

Hi Dave, There is some FM allowed on 10 meters, higher than 29 MHz, and I wondered if you had yours working to at least receive FM. The xtal filter might make that impractical (I gave it some

Hi, I've been busy with client projects as of late. Looks like most of the uBitx issues will be solved by the time I get back to playing with it. That is good. I ran across this fairly low cost

You will want to move to the current firmware and memory manager (currently 1.1 but 1.097 will work as well).? I'm not sure there was proper S-Meter function in 1.07x.

Sorry not deviation meant amplitude. 1khz signal 50% amplitude. I also did a zero beat against a 7.150MHZ signal 1khz using my signal generator to transmit and then listened on my commercial radio and

Sunil is not sending goods with a value less than $25 at the moment. Something to do with DHL and no India post. He will cancel the order if it's less. It has just happened to me. 73s Ken

Hi Dave, Did I miss something? Deviation is an FM measurement unit. I didn't notice that you are using your uBitx for FM. Are you doing that with SDR software? 73, Bill KU8H -- bark less - wag more

John, Sunil sells his front board / wiring kit a la cart for $15 + shipping. https://amateurradiokits.in/product/wire-kit-and-board-for-front-panel-ubitx-case/ No difference in v3/v4 board wire-up.

I have a working S-meter under VK2ETA version of KD8CEC firmware. I am using a 1602x2P display. However, when I implement KD8CEC's v 1.071 I cannot figure out how to enable S-meter in the display. YES

That should be 'good enough'. You might have to pay a little more attention if you want to use the rig in a frequency measuring contest. That isn't necessary for just everyday operating. 73, Bill KU8H

Pretty much according to the instructions...? Set the CAL to zero beat against my 20 MHz reference standard.? Then adjusted the BFO until got a good RX signal.? First used a signal from another

I bet that Wiki is cool but it sure is nice to get the info LOL

Does any one have their oscilloscope peak to peak volts measurements for the receive transistors (with a specific signal generator volts/ of of course)??? Q10,11,12 base and collector and Q30,31,32?

The latest version is v1.28.1, but v1.27.7 should also work OK. It should work even without any of the modifications as described in the instructions. However, I would recommend to at least install

Evan, it is simple. I uploaded a file refresh_eeprom.ino ( i GOT IT FROM MY CLOSE FRIEND OM MAHESH VU2IIA AND WORKED FINE FOR ME) 1. place the usb card and connect it to your laptop. Of course I use
