Fixing a blown Raduino board

KC9SGV
 

Hi All,
I managed to fry my Raduino board somehow.
The board is hard to come by at the moment.
So, I ordered the parts via Ebay.
Looking good so far...
 

I did that twice. The best investment I have made in a long
time is an 40 watt soldering iron with a built in solder sucker.
Worked really well for removing the nano I love it.

Antenna connected.
Refurbished Raduino in place.
Allard's latest BitX40 sketch.
All necessary hardware changes for the latest sketch made.
No radio signal, but spurious noise over the band plus the 7.200 birdie hissing loudly.
What am I missing ?

Allard:

Is the code for the BiX40 backwards compatible from the code for the ?BITX?? Could that be an issue for this guy?

No, the BitX40 code and the related hardware mods were developed specifically for the BitX40.
The code is NOT compatible to the ?BITX!

I use?Raduino_v1.27.7 for BITX40 - Allard Munters PE1NWL
What is that ticking noise with the DDS knob stationary ?

Bernie:

Usually a "ticking" noise is caused by communication
between the chip and the LCD. It may not be that, however.

Anyway it is a kind of "normal" RFI from a uPC. Usually it can be
eliminated with proper wire dressing or shielding. Most uBITX'ers
have used shielding on extension cables for the LCD because
that is when they hear it.
