Taps and Scratchs on PCB heard on RX

Hello All,
I used small wire sleeves on each leg of every transformer and inductor to provide mechanical stress relief. It was my opinion that direct soldering of these inductors may break the magnet wire if its constantly bent and unbent . The manual doesnt call for this however.
Anyway, with no antenna connected i hear the mechanical scratches and taps on the PCB through the receiver; akin to the classic LC VFO issues when the coils were loose. However its only the bandpass filters and transformers that have inductors and wonder why i was hearing these?
Request you guys to test out ur rigs and let me know if hearing the taps and scratches is normal or not please.
listed are the conditions i tested it
With no antenna connected the default uncalibrated scope on 20m shows a noise floor of~ -125db and raises to ~ -110 with a bad(indoor 20m dipole touching floors and walls) antenna connected. The builds is for 30/20/17/15
Any thoughts on the mechanical stability of transformers and inductors and its effects? advise on "glue on top" when all seems fine tuned or the sleeves are entirely to be blamed?
With the antenna connected i don't hear these mechanical noise any more.
