Ages? back Ashan? or Ashar published a whimisical schematic where he used on of the Si labs offerings to potentially become an FM VHF as in NBFM generator. Does anyone recall how this was done and

My PICKit 3 got here a day early so I proceeded to rip into my UBITX and tweak the tuner programming.? The video https://www.youtube.com/watch?v=dPys_-_wPcQ nails the process and I had no problems

Bob - I have ordered the "through-hole" version since I am a lot more comfortable with that type of construction.? I will read more when I get time. Pierre - That's not a bad price especially with

Jerry Hang in there, and perhaps this way more of it goes to hard working people who kit these. It is quite an interesting rig, but not one I would necessarily recommend for 600 watt operation. Most

If you had ordered from Giga Parts in the US for the same price you could have had it tomorrow :=P John

Hello all! QRZ, is the frequency in use? Last night, on a whim, I ordered a uBITX v6 from India. Anybody know how fast they ship? Kicking myself this morning because it's also carried by gigaparts,

Correction to earlier post. It does appear that on the uBITX schematics, some leads are marked with an "x", but as Raj has said, they are not connected to anything else. Arv _._ [email protected]>

In this case, an "x" means no connection. In the uBitx schematics, the remote connections that Arv describes are drawn as text inside a box with a pointy end. An example of this is "CLK2" in the upper

In conventional schematics it is sometimes necessary to show connections as an "x" or something similar. This is because showing the connection between two points might excessively complicate the

I like building and have built a BITX 40, uBITX, QCX, QCX mini and a Barb WB2CBA v1.02 uSDX. The first thing to know is that unlike the uBITX or QCX, there are several hardware variants with different

Pierre, It means that those windings are not connected. HFSignals winds all transformers identically. In places where a bifilar (2 windings) is required they leave the 3rd winding disconnected. It

Could a member explain these odd things I find on the schematics wiring of four transformers : - T5 : wires 1 and 6 end in a x ; - T6 : the same ; - T8 : the same ; - T11: the same with wires 3 and 4.

Robert - That's about what I was figuring, definitely no more than that and maybe less.? I already have a few Nanos since I couldn't use them on the Raduino with the header soldered on opposite and

My PICKit 3 programmer should be here Saturday so I'll let you know how it goes, if I don't brick it!

The phases I gave in the post included below for the various impedances when doing an AC Analysis in LTSpice of the Q90 uBitx stage are incorrect. When LTSpice measures current through a device, it
