Definitely worth the extra $10 for DHL

Dave,
Having built a couple fo the Bitx 40's.  Always a good practice to establish a baseline.
Get them running as a stock rig....then
Incrementally add modifications (one at a time) and then test the rig through all the baseline functions and the new function that your mod added..
once convinced that it works with no hork-ups, hiccups, or wiring errors then move on to the next mod.
Document all your changes in case you have to back stuff out.

Ordered mine on December 18th. Got notification of shipping DHL on February 7th and it's due to be arriving today the 9th.

I orderd mine on the 5th - it was $109.  I thought the price had gone up but maybe I'm lucky somehow.  Looks like I'm in for a long wait as I decided to just go with India Post because I have several other projects going on and waiting a wjile is OK.  Am I right thatI will get no notification of status until the rig actually ships?   And how long will I have to wait?  From what I can gather it's about 2 months before shipment and the a month in shipment.

CW Autokey Mode is just builtin Memory Keyers.
uBITX Manager will save the text and use it. Be sure to set Key type to IAMBC before executing Auto Key.
I'm sorry I can not post the explanation on it yet.

The following image is a test image of uBITX Manager running on Linux. Auto Key Mode was also used.


Thanks for your interresting

I ordered mine on Jan 27 via India Post. I received order confirmation email on Feb 1. The confirmation email does not indicate ship date, only that they are doing their best and orders will ship in order received.

Cheers,

No power increase with higher voltage?

 I am still befuddled by this. My BitX40 has Q13 replaced with a 2N2222A, and has R135 turned almost fully CCW in order to get the desired drive level with this replacement. I added the back-to-back diodes at K1 pin 12 to ground to avoid a repeat issue with Q13. I am currently running 13.6v to the rig, with the main board and Raduino powered off a 12v regulator, delivering 11.5v at this input power. The PA is supplied the full 13.6v, or 24v through a separate voltage booster. I am reading the desired voltage on the tab (source) of the PA transistor, either 13.4 or 24 as selected, and 3.9v on the gate and 0v on the drain at either voltage during transmit. Bias is set to about 100ma and PA current draw goes a bit over 1a with modulation. When I transmit at 13.4v I am getting 7-8 watts out, as I expected, but when I switch to 24v I am only seeing 6w out. The 24v does not sag. I have traced the wiring, measured voltages, made sure all grounds are common, and frankly just don’t see why this is. Any ideas?

 

I do notice, at least on the DVM I am using, a spike in PA source voltage with modulation that might peak at close to 70v, while measured at the booster or power supply it stays pretty steady. Is that normal? I am guessing it is RF getting into the DVM. Otherwise, everything seems to be working fine. The transmitted audio sounds fine and I have made a number of contacts.

The DSL package arrived this morning. Got to find time to play with it. It has been a long wait ( ordered 16th December ). 😁

Tim : 

The CM-500 is used connected directly to the radio.  I originally bought it to use with my Flex-1500 and have found it to be an excellent headset
(on par with a Heil Proset, but at a fraction of the price).

Since the LCD consumes quite a lot of current

Nope, the LCD is in fact very low power consuming device...

The power how is the beautiful LCD backlight (in my case with a big 4x40 chars was around 1A, the 2x16 ones can move between 100 to 500 mA)

I implemented that in a non ham radio application (PIC not Arduino, but same principle applies), all the bits are in the different answers to the question, I resume them:
  • Cut the feed for the LCD backlight from the +5v for the Arduino (just the backlight will be enough), use another 7805 for that or a simple R divider if you current is not so high.
  • Put a conducting diode in series with the +Vcc (12-16) volts to the Arduino +5 volts regulator.
  • Put a big cap from the Cathode of the diode to GND, this will preserve the +Vcc to the arduino regulator (the 78xx family needs 2.5 volts above the regulated value, so you need to maintain it above 7.5v the time enough to write to the eeprom)
  • Tweak to find the optimum value, in my case I used a PIC18F4550 and a few other low power devices down the +5v line, including a 4x40 LCD..., I was fine with 2200 uF/16V not fine below 1000 uF/16V.
  • I tested a few tricks to detect the power down state, the most effective was a pin change interrupt with a low tech solution:
    • A 1k resistor directly from the +vcc to a 3 silicon diodes (1N4001) in conduction state, decoupled with 100p
    • That 3 diodes raised the pin to a safe 2.1volts wen powered, well beyond the 1.8 volts gray zone of the digital pin.
    • As soon as the power goes down the pin will fall to zero volts, then a interrupt routine will do nothing more than write the settings values to a EXTERNAL 24L08 via I2C...

Mine isn't even here yet and I already know that I should have ordered 2, one in production and one in pieces.

Do you have a list of the components by designation Ex: R1, R2, C1, C2.
The pcb does not show values only designations.

As posted in the original sale thread here is the site where all this came from: AGC

10k is on the IN 100k to GND right after the .1uf cap next to the 2n3904.

Sweet.  I used the same case but I really like the wood front panel idea.  And a popsicle mic.
