did you use the output and ground to replace the crystal?or was other action necessary?

I was wondering if anyone has tried using the Raduino as a VFO to replace the crystal on some other QRP radios to replace the crystal like the Rockmite II, the 49er and other small minimal power QRP r

My advice is get rid of windows and go Ubuntu if at all possible ... lot less problems..

not sure where the audible cliek comes from, but changing the encoder to one without clicks removes it.. plus you can move around the band much faster..

Many folks change out the encoder to one that doesn't have clicks. This is what I prefer, to each his own. Here is an example of what I am using. You will have to get a 5v line to it but other than th

I took the antenna off and tested the uBitx straight into a 50 ohm dummy load and it performed flawlessly on the upper bands as well. I don't have ferrite beads I can use at the moment but will get so

Thanks for the info and suggestions. The uBitx is in a metal case designed for it, one of Sunhil's cases. I also use shielded wire between the key and the radio. I will run some tests with the dummy l

Thanks for the help folks. As always, you come through with great ideas. I will try these tomorrow.

Using ladder line from random wire antenna to the tuner. Tunes perfect 1.1 to 1 SWR, where would I put the ferrite? in the coac between the tuner and the radio? Or between the tuner and the meter? Thi

I have a V5 uBitx with CEC v 1.22 firmware and using a straight key. It works great on everything from 40 meters and below, however on all bands from 20 meters to 10 meters, when I press the key, it l

I am sure one could modify it to match up to the Bit40

uBitx v4. It will work on any ubitx but is the redesigned with the replaceable Nano.

Thanks, will look at that in a bit.. appreciate the suggestion.

I have a V3 that just quit transmitting. It appeared the finals just went out. I replaced the finals (used sockets per advice from another user) and still no output. It is a good thing that I put them

it would be a nice option to be able to purchase just the uBitx v5 main board only. There are several who have a v3 radio that would like to upgrade but already have all the hardware, wiring, pots and

is it possible to buy a uBitx without the Raduino?

I have one of those kits that I decided not to use. It is just as received from Sunil, if interested, let me know.

I like telling them they are S 8.367...

I have both. Two different radios. They have a lot ifsimilarities, a lot of differences. If you are only going to get one, get the uBitx as it is the entire HF band, not just 40 meters.

Thanks, John. Will give it a whirl.
