Christopher, Off chance, have you checked the output of the 5vdc regulator on the Raduino board? If the regulator is toast, then you could be wiping out the nanos on over voltage (an known issue for

It may also be a bootloader issue. Recent Nano's?come with?a newer bootloader: https://forum.digikey.com/t/january-2018-arduino-nano-bootloader-update/1194 73 Allard PE1NWL

Pete, Andy is correct, you need a more recent version of the KD8CEC software as the S-meter appeared in version 1.08 of his releases. 73, John (VK2ETA)

Now, that brings up another idea. Some of the computer/laptop power supplies have a 12V line and also a 18/19V line. But it the two power lines are separated and the radio used the 12V line, the amp

I agree with the other posters that it's a useful instrument, if you know its limitations. Using the RF Explorer, I was able to confirm that replacing the relays on my ubitx rev 4 board cleaned up all

Laptop switching power supplies are cheap, often available in thrift stores for pennies on the dollar, and can power the PA section. 19 V is common. A cheap switch mode 12 V wall wart can handle the

As Bob suggests, a simple old school wallwart consisting of a transformer and a rectifier is generally not suitable for powering electronics such as an amateur transceiver. The open circuit voltage

One comment in this user's comment makes me remember something that no doubt others know but it may still be useful for someone who has not heard it before. Some people pick up a wall wart and see

I noticed today something else interesting. Even though I can get the same receive 1khz zone on both my yaesu and ubitx on the same frequency.? When I transmit from ubitx to my nearby rig the Yaesu

When I connect a serial monitor to the arduino, I don't get any data out of it.?? I've also tried to hook the arduino back up to my computer to burn the new v1.28.1 code to it and I have the exact

Thanks? John,Glen and Gary for info on the front panel boards.? Just finished wiring a kit I received a week ago but having the boards makes a much cleaner radio.? I just ordered one also along

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
