Not yet, I have decided to re-model the case, and install my RaduinoI2C board... Also mounted a swr bridge... Gonna be a nice little rig if I get reasonable results from the PA mod..

Thank you...Jan 18 is getting closer!  My 7 and 9 year old helpers are getting eager to "talk to someone" and not just lookup WSPR spots on the globe.  Sadly, my 12yr old asked "do you 3 really think that is fun?"

Re: uBITX Mic Wireup

Dave Bottom <ars.kd6az@...>
 

Connecting the Mic- to ground to generate PTT is common for many handheld radios. It saves a wire in the cable.  

You’ll need to rewire the Mic and PTT SW to work with the uBITX which is exactly the way you would wire it work with most QRP radios including Elecraft’s KX2/KX3 radios.

 Does anybody have a diagram or description of the mic wire up for the uBITX? I am looking for the mic itself, not the mic jack on the transceiver. Most of the mic's I have dealt with have the MIC+ going to one side of the electret and MIC- or ground routing through the PTT switch when it is closed, completing the circuit. Looking at the uBITX schematic and a mic wireup for an older version of BITX from several years ago on the forum, what I think I am seeing is that the sleeve is providing a constant ground to both the MIC- side of the electret and one side of the PTT switch. The tip connects a constant output to the other side of the PTT switch and the ring is providing a constant output to the MIC+ side of the electret. It almost looks like the electret is an "always on" state but the output is not utilized until the separate PTT circuit is completed. Any help would be appreciated.

Re: Variable power control

_Dave_ K0MBT
 

I have been powering my bitx40 with a 3s Lipo battery Nominal voltage 12.  last night I thought maybe I could put in a LM317 and set the bias for 12 v and power the radio with a higher voltage lipo. Leaving the power for the power amp at battery voltage. it would be easy enough to change batteries for different power levels.

Things didn't go quite as planned. I think some RF may have gotten into the regulator (a guess) The regulator became quite hot even though i had put on a power transistor to carry most of the load. The sensitivity of the radio was noticeably less. I stopped the experiment for now. The Bitx is my only radio and I didn't want to burn something out. .

" We finally located a source of brand new, high quality TDA2822s that are currently being shipped."

I placed an order few days ago... Does that mean that I will have normal chip that doesn't need any mods? Maybe just lowering voltage with 78L09?

Re: The issues of the TDA2822

Gary Shriver
 

That’s a great question.  Mine was shipped two days ago.  Will it come with a 7822 that won’t require any mods?
Thanx-Gary

Re: Pulling Arduino data apart

Jack Purdum
 

Take a look at the wikipedia entry down at Files and Byte Swap. That shows that machines that use different endians must account for it when reading data, be it from a file, a DB, or a COM link. That's all I was trying to say. I know this to be true as I've seen it demonstrated. Making code endian agnostic simply means that the code account for and adjusts to the different endians. The example uses a different algorithm than yours, but the fact you have one means that somewhere it must be accounted for.

I realize you don't want to admit all of this, but either we're talking at cross purposes or you're simply wrong. Either way, I'm not going to convince you, nor you me. This ends it.

uBITX Firmware CEC Version Added WSPR function, I am looking for a beta tester. #ubitx

Hi Ian

Thanks a lot for the latest update with the wspr function.

It is now working fine after adjusting the tx frequencies by hand for the 3 chosen bands, 40, 30 and 20m.
The signals have reached all continents except SA with my vertical delta loop antenna..

Is there a way to reduce the output power in the future?

Endian issues...final chapter

Jack Purdum
 

All:

Jerry and I have continued to argue offline about passing data between machines that use different endians. (The endian idea is that an int data type can be organized in Big Endian or Little Endian, that is, are the two bytes organized as Hi-byte/Lo-byte or Lo-byte/Hi-byte.) His position is that C code is endian agnostic, meaning you don't have to worry about it. My position is that any communication between those two different endians must take it into consideration.

Jerry found a good discussion at:


In that reference, the Files and byte swap sections states:

    Endianness is a problem when a binary file created on a computer is read on another computer with different endianness.

which is what I was trying to say all along.

Anyway, I said I wouldn't waste anymore of the groups time on this, but I thought the Wikipedia source Jerry found kinda settles the issue...at least it has for me.

Re: Pulling Arduino data apart

Jack Purdum
 

Arv:

I understand your point, but some of us are doing things with the µBITX that does cross platforms yet I still want the code to work on multiple platforms. I think Ashhar made the Raduino "detachable" for a reason, and one of those might be a different microcontroller than one from the Atmel family which uses a different programming platform. There's nothing inherent in the design that would prevent that. Indeed, I'm doing some work on several different microcontrollers, languages, OS's, and displays for the µBIT.

Also, my discussion started about using a C union data structure and some of the advantages it brings to the programmer. My experience is that many beginning programmers don't use it because they don't know how it works. I apologize that it degenerated from there.

uBITX Firmware KD8CEC - IF-Shift etc.

ge_clipboard
 

Hello Ian and All

The sound of SSB signals with my uBITX are very strong on the high side. In LSB I can adjust the received sound with the IF-Shift with a very pleasing effect, but this does not work the same with USB. And I have noticed, that using the IF-Shift, does also influence the TX signal where the output is becoming a DSB signal with lots of power in the other sideband. I have also tried to adjust the BFO, but without positive results.

Would it be possible to have the IF-Shift function just with the RX and leave the TX on its own? What am I doing wrong?

I ordered mine January 12. I received notification from PayPal yesterday that my uBitx has shipped. I didn't use DHL for delivery to the US. What I've read here in the forum and ubitx.net/ delivery may be within a few days or up to several more weeks due to Customs.
