Re: Raduino v1.10 with CW functionality released


 

Larry,
I know what u mean, mods are keeping me busy.? I have 2 bitx40s. One I keep on line nearly 24/7. The other i keep testing and adding mods.
On my test unit i run a homebrew dds sg5351 and nano.? I also do what you do and plug a spare nano in for testing various firmware versions.
I wish the raduino dds nano a socket. Recently thr raduino dds failed, weird as they are quite reliable but she would not load a sketch..... So, i removed it, added a socket and put a nano nano back in..... Works fine now.

Mods:
Added the usb mod
Rf gain
Larger heatsink
Tx display
Ptt thump killer
Rvs voltage protection
Frontend diode protection
And the list goes on .....

Great little rigs

Joe,
Thanks for your reply.? I thought I saw your QRZ station pictures a while back!? I was surprised when I saw you where in the contacts! ?
Mainly the first time on JT65 for me in the receive mode.? I have a few Nano PCB's here and I set up my DDS with a inline headers so I can pop a Nano in for quick comparisons. I have v1.11. ?
Bitx here is getting power from a 12v 18AH sealed lead acid battery.? JT65 is loaded into my old laptop running XP.?
I'm dragging my feet on putting the BITX40 into box!? Mods are coming faster than I get around to installing them Hi?

LARRY,

Will keep an eye open for your jt65 transmission.
Rig is on most times
Just with casual usage, I have 80 contacts on jt65..... Lots of fun
Running raduino v 109 but will be moving to 112 on its release.

For what it’s worth:

This morning finally managed to get the BITX40 to receive JT65 (with help from longtime friend: K9HWL).

My second attempt I set the WSJT-X software tuned to 7.076 USB and nothing.

Then I heard something and looked up watched a QSO exchange!!


WD4RC? ?CQ??? AL

M0ZCW ???England

W8KHR ???Ohio

VE1BWV ?Canada? ??I think I’ve read your BITX40 emails? JT65?

W1GQQ??? ?NH

US1CR ????Ukraine


My trap 80-10 dipole is up 10’ and level E/W

Now on to making the CW mods for the BITX40? -? JT65

Just thought to pass on my this step with the BITX40

Thanks to Allard PE1NWL for all he’s doing.

I've just released raduino v1.10, download it from

Some minimal hardware (a few resistors and one PNP transistor) is required to fully use the new functionality.

New in this version:

  • added CW functionality (for straight morse key). This function can also be used just for tuning up. This requires the CW-CARRIER line connected to Raduino output D6 (connector P3, pin 15). (see for wiring instructions). The morse key itself shall be connected to Raduino pin A1 (brown wire). Both sidebands (CWU or CWL) are available for CW operation.
  • Semi break-in for CW This requires the TX-RX line from Raduino output D7 (connector P3, pin 16) to override the existing PTT switch using a PNP transistor. (see for wiring instructions)
  • CW side-tone This requires some wiring from Raduino output D5 (connector P3, pin 14) to the speaker. (see for wiring instructions). The desired sidetone pitch can be set using the Function Button in the SETTINGS menu.
  • Frequency tuning is disabled during TX (to prevent flutter or "FM-ing" during TX). This requires the PTT SENSE line connected to pin A0 (black wire). (see for wiring instructions).
  • Please carefully read the updated user instructions:
