Mouser carries "detentless" encoders for under $2, so unless you value your time at less than 10 cents per hour, why not buy one or go big an buy an optical encoder.. The resolution depends upon the

Call me crazy but I find the clicking annoying on a receiver, unless it’s a field radio where the resistance can be an advantage. Haven’t seen it on a premium receiver, won’t say none have

I have several commercial devices that ALL have encoders with detents.? I have no difficulties operating any of them.? So I have to ask the question why not do the same with your uBITX?

A mod I have done on a couple BitX rigs now is to add a 12v regulator on the line supplying power to the main board and Raduino. Even with a 12v supply the supplied voltage stays up around 11, which

Electrically, all the grounds are the same DC-wise (note, the heat sink on the PA is NOT at ground potential), and any single point ground, such as the tab on the BNC connector, should be fine

Hi I have a couple of the excellent monoband ILER QRP both equipped with a plug and play AGC. I am wondering whether anybody have adapted it to the ubitx.

Prabha jee, i like white color jilebee. . If you have seen what HF Signals supplies with ubitx, it is silent , no dents or ticks.

Try 38400 not 384000, just a thought. John

Why are so many here hating detents in rotary encoder?

Getting even more interesting... Your sheets show 0.8A for the 2N2222a and 0.6A for the PN2222a..However your 2N2222a is in a TO-18 case, whereas, the spec sheets that I was looking at were both TO-92

Of course Allison may have real-world experience that show differences from datasheets...

Hi, I tried to find sheets coming from the same manufacturer.? The ones from ON showed pretty similar max collector currents (probably they are not running up there anyway) and big differences on

Perhaps Allison who suggested 2N2222 metal case ,did not mean against PN2222. [email protected]> wrote:

yep this is a key step, the digital cable goes onto raduino while analog goes on the board.? i had to stare at one of Sunil's assembly pictures for a long time to figure out which is which,? on mine

Interesting The differences are minimal, however the datasheets that I found indicate that the thermal properties are exactly the same for both, but show the max. collector current to be 1 amp for the

Looks like I installed more headers than are in the kit. no biggie I'll just remove them and direct solder. where do the analog and digital cables go? There is only one connector on the main board.
