Re: Teensy I2c on wire2 (SDA2/SCL2)
#ubitx
There is a separate library for Teensy (i2c_t3) that comes as a built in library in the Teensy add-on for the IDE.
It is supposed to handle Wire1, Wire2, Wire3, and Wire4 #include <i2C_t3.h> instead of #include <Wire.h> But apparently the LCD library may only be able to access Wire1 N5IB |

Oh wow. Allard I didn¡¯t know you were the creator, It¡¯s a good service. Btw just got notice that there¡¯s some Sporadic E on 6meters right now if anyone wants to have a go at it lol.

PTT Question
Hi guys, I'm going to build up my uBitx and use a standard 4 pin mic jack. ?For some reason I'm not used to seeing the circuit drawing of the jack in the Wire Up so this is my interpretation.
I just want to make sure that I have this correct. Violet = Mic + Blue = Mic GND Orange = PTT Shorting between Orange and Blue will trigger PTT. ?Is that correct? Thanks, Curt |
Re: uBITX -Regarding the PA transistor heatsinks.
I was lucky in the box I put my uBITX in was just large enough to fit the display out? a hole in the front and the heat sinks out the back.? When I changed the final transistors the tab was at ground.? Then I bought a large heat sink and fastened it to the box and bolted the transistors to it.? That gave me a heat sink about 3 inches tall and 4 inches long with some vertical fins. On Fri, Jun 1, 2018 at 3:31 AM, Peter LB0K <lb0k@...> wrote:

Allard I use this service DXRobot. I get audio alerts on a simplex node I use that gives me propagation alerts. I get alerts everyday when 6m is open

Re: uBitx sound
So we already have a filter to cut audio outside the 700-2800 range?? I was building a SSB-Mite from 4 State QRP Group.? I searched the messages for it and did not find anything.?? Can you tell us where in the uBitx schematic it is.? Curious to compare it to the SSB-Mite.?

Re: Teensy I2c on wire2 (SDA2/SCL2)

I don't think the issue is the bus voltage.
The issue is getting the SDA2 and SCL2 pins to work instead of SDA1 and SCL1. The Wire library seems to only handle SDA and SCL, not any of the other SDA/SCL combinations available on the Teensy. tim ab0wr On Thu, 31 May 2018 23:31:32 -0500 "AA9GG" <paul.aa9gg@...> wrote: Haven't tried it, but remember that the si part is running at 3v and |

Re: BITX QSO Afternoon/Evening, Sunday, June 3, 3PM & 7PM Local Time, 7277 kHz in North America, 7177 kHz elsewhere.
Wouldn't be easier to set fixed UTC hours instead of local time? Local Time just too dispersive in my opinion. Il 01/giu/2018 13:07, "John P" <j.m.price@...> ha scritto:

Re: The new uBITX boards are here
Daniel Conklin
Bob,
The "old" board works well.? You will likely be happy with its performance.? There are some mods and kits for mods available to fix the few minor issues that may or may not bother you.? If you read up on ZL1AXG, Mike's blog, you will find useful information on those things, but it is recommended to first assemble your radio and try it as-is.? Have fun and learn a lot!?? Dan, W2DLC |
Re: uBITx For Sale

Hi, Richard,
I have a recent spare that I will not get around to for a long time. Completely unopened. Prirce is the same $109 by paypal to "jean (at) g2ideas.com" I will ship by priority mail to the US address you provide. Shipment outside US would need to be discussed. 73, Paul K2AYZ |
Re: The new uBITX boards are here
Good news... bad news.? I just received the "old" board a few days ago.? :-(?? Will there be a retrofit parts list and modification instructions?? This would greatly simplify the process for many willing to give it a go.? I prefer to make the mods prior to assembly into the case.? Thanx - Bob W8RMV

Join us as we make contacts with our BitX-40s or uBitXs or anything else on 7.277 MHz in 40 meters! This is a worldwide event for BitX40 (and other QRP)?stations starting at 3PM and 7pm in each time zone. To participate, call CQ BitX on Sunday, starting at?3PM and/or 7PM?your local time. The BitX QSO Night continues through the evening and conditions usually improve after sunset, so it is worthwhile to participate later in the evening. Suggested Best Operating Practices: Work at QRP power levels unless conditions require more power. Report your QSO's, discuss propagation, noise, signal reports, audio reports, antenna type, etc. in this thread. This is an undirected, scheduled event.? The BITX QSO Night relies on you to call CQ BITX to initiate contacts with other stations, so warm up that final and transmit a few calls on Sunday evening.? Talk to you then! |
