Its been a while since last post about #meshtastic 868 #cavity filter build
(https://techhub.social/@gafu/114162745391415705)
I build 2 pc of the long one with 3 elements, and 2 ones with 4 elements.
I got different unwanted spikes and now i know where they came from: its related to the lenght of the coax wires.
With more elements it get difficult to bring each element to the right resonance frequency, so i soldered brass m4 nuts to the cap and installed brass setscrews on top of each element.
I fidddled around with aditional decoupling wires to get deeper filter response.
In the pictures you can see the filter response from the better one of the 4-element type. The Markers are in or close to the local used GSM/LTE cellular band
"Tell me my origin story again," said Nierex. He loved this story.
His mother unfurled cilia indulgently. Truly, none of the millions she'd spawned had been like Nierex.
"I noticed your broodmates were disappearing. So I hid those of you who remained in my abdominal #cavity--no predator could get you there! When I thought you were big enough, I spat you out."
"The others didn't survive your stomach acid, but I did," Neirex said happily.
His mother glowed with pride.
The light reflected off the sterile white porcelain fixtures and garish blood-red splashes. How dare he say she had ten cavities? Ten! No way insurance would cover that. The dentist and his assistant wordlessly asked, “What will you do with us now?” But she knew. There were dozens of undiscovered caves in the hills. The pair would fit nicely in one of the smaller cavities.
She laughed at her little joke. Cavity.
