Re: The new uBITX boards are here
Farhan,
That link for PDF seems split into two where the left most is the new
version and right most is old one!

Re: The new uBITX boards are here
jerry,
yep, that's it. There are very subtle changes to the PCB layout. I have brought the audio connector in-line with the raduino connector. This will help us in the future while using a DSP enabled controller board like the JackAl.

Cap C81 at the Q90 emitter is now 470pf instead of 0.1uF to reduce gain on the low bands
in that first stage of the transmit amp chain.
RD15/RD16's can be stuffed as an alternative to the IRF510's without having to cross the source and drain pins.
Is that it?

Rah, the new schematic shows up in the ¡®Circuit Description¡¯ tab but the link from the schematic brings up the Raduino circuit. That link needs to be fix to see a larger printable version.? Thanks Farhan for updating the board and information.?

All in all, the changes are 'backward compatible' . That is, you can hack

I can't see why not. However perhaps a better choice is, from memory, the HF Packer. I had one but sold it when I moved. I am wishing I had not. Please Google the amp. I am sure you will be pleased by its attributes.
Hello everyone i want to amplify the output and i want to use the amplifier that will give me between 30-40w as output i found tge Mx-50pm which has good price and good reviews but people use this amplifier to yaesu 817 and for the KX3 so can i use and in addition my output is 5 watt approximately in 20m and 40m and 80m and the 10m it was 2 watt?

Raduino 4 Line Single Sided PCB boards
Hi! Friends, I have designed a homebrew friendly Single sided PCB for Raduino in a form factor of 20X4 line LCD. This board? supports 2 line display as well. I have added some minor edits to orignal Raduino schematics that is self explanatory namely few more electrolytics, separate Analog Digital ground plain, Nano module on component side to make it plugable. Largely thru hole components but SMD pads also included for coupling and decoupling caps. All fabrication files are being made Open Source for personal and club use only. Please verify the Gerbers before making the board. Your feedback is highly appreciated for any further improvements. Enjoy & 73 Rahul VU3WJM

Re: BITX40 CW Carrier Mod - CW Waveform shaping ?
#bitx40
I verified that the stock uBitx code does correctly shut down clk0 and clk1 during CW transmit.
Turning them back on takes awhile, as all the computations get redone and all pertinent si5351 registers loaded.
We could speed this up by several milliseconds by talking only to the si5351 clock enable register
Might be significant for some high speed CW operators.
// At start of CW transmission:
i2cWrite(3, 0xfb);? ?// clk2 on, clk1 and clk0 off? ?
// At end of CW transmission:
i2cWrite(3, 0xf8);? ?// clk2 and clk1 and clk0 on
You also must change clk2 to the operating freq and back.

On CW transmit, the VFO is moved to the operating frequency, and we can shut down clk0 and clk1 entirely if we wish.
If clk0 and clk1 remain active during CW transmit, we could be transmitting stuff from the mike at at 45mhz minus the operating frequency.

Re: The new uBITX boards are here
Perfect - thank you.? I will be using this rig mostly for
Propnet PSK31 on 10M, so wanted about 4-5W output.?
