Re: No receive audio from antenna, Bitx40 #bitx40

After checking the voltage on Qx inputs, I discovered that the radio is in transmit mode.  It went to receive with sound when I pull the PTT connector wires.  The mic/ptt is wired wrong.  Time to review and perhaps start from scratch on that part.

Wait. I'll merge it to 1.02. Download it for 5 minutes.

I have coded too much, so I do not have enough space.
Please speak if you need more space for the program. I will exclude some features.

HI Ian,
Can we get the source for the latest version please? I need it to implement my TPA2016 and I2C display....

THanks,.

Hi Ian,
Yes, I did run out of space. I removed some code for the default HAM BANDS and that allowed me to include the extra for the I2C lCD and TPA2016...
We need to test the hardware hack for the voltage meter for EPROM saving on poweroff then reduce the code more... lots to do...
Great work from you so far, well done on an excellent version of the FW for the uBITX.

Hi again.
I think also the hardware hack version can save space by moving the keyers to dedicated digital pins freed up from the LCD to I2C mod. we can then remove all the analog input calibration code...

Re: #bitx40help Probably need new Raduino #bitx40help

Hello Raj and all,

Thanks Raj, I did indeed find that D7 was blown.  I unsoldered it from the board and tacked a 1N4148 in its place, paying due heed to the polarity of the diode.

I had taken the raduino and its display unit out of the BITX40 and connected it to my computer USB port.  It lit up and behaved as it should.  When I put it back into the BITX40, it does not light up so I have now to track the voltage path and find where it is getting blocked.

Just another day of fun detective work in this antipodean paradise.

I also tried to erase it first.
I wish your project a success.

Hello all,

Replaced D7, then found fuse blown. Replaced fuse, applied power, and raduino display lights up.  Rotating the tune pot changes frequency.  Only problem that is evident now is an intermittent connection at the power input.  I can replace that and see where we go from there.  Again thanks to Raj.

Ashar, the link to the zip file containing the BITX40 circuit diagrams on the HFSignals site is broken.  The link points to the old HFSigs site so clicking on it results in file not found error.  The circuit diagram that appears under circuit description is too out of focus to withstand any enlargement.

Micro BITx Audio Pot

Robert Goodwin
 

What is the shaft size on the provided audio pot in the uBITx?  It was 0.16 in the BITx40 but pictures of the uBITx parts make me think it might be different in the the uBITx.  I'm trying to get all the parts that I have to provide together before the kit arrives, and this knob is of interest.

Re: Micro BITx Audio Pot

 

Bob,

Same as B40. I have used the standard pot so that I can use the 1/4" shaft knobs.
Almost any audio taper pot from 5k-50K(A) should work. You could repurpose from
some speaker amp or defunct audio equipment.

Hello, Kevin.

Try zooming your browser while looking at the hfsignals BITX40 Circuit Description page.  At 150% it's quite legible.  You can also right click on the schematic, save the images, and print them.

Attached is the png file of the main schematic.

Re: Second batch of uBITX shipping? #ubitx

Hi,

Ordered 16th December and arrived in Germany just 24 hours after shipping and now at last Red Letter Day, it took the Customs in Leipzig 2 weeks but finally cleared customs and I have my UBitx.
Can't wait to get started.

I have had success in selecting a section of the schematic on my desktop, enlarging it and printing that section. I did it with the Q14 Q15 section for ease of viewing and a help in troubleshooting. This section does have 2 known wiring diagram errors however. Trying it on my iPad resulted in fuzzy copies. 73

What's different between the two versions?  (I didn't notice anything at first glance, and I'm still short of coffee this morning.)

Another error on the Wiring UP diagrams (all of them) show the CW Key connected to pin 2 of the key jack.  Pin 2 is the RING terminal, not the TIP.  It is customary to connect a straight key's contacts between the tip and shell of the plug and the paddles normally (but not always) have the DOT paddle connected to the TIP and the DASH paddle connected to the RING terminals of the appropriate key jack.  

This has been mentioned MANY times by myself and others and needs to be changed so the newer people building the uBITX have the right information rather than wiring their rigs up wrong and having to change them later when they find out CW doesn't work.
