Re: Spurious RF at beginning of CW transmission in the uBitx

 

This is the first I have heard of this issue on the uBITX.  

There was a similar issue with the BITX40 and Allard, PE1NWL implemented a code workaround to suppress it by temporarily shutting down the Si5351 CL2 for about 50ms after PTT closure, to let things settle down before allowing the rig into TX.
