Subject: [TSSP] Low Sonotube Q - It's the water!
Hi All,
I took my smaller bare Quik-Tube and sprayed it lightly with water to
see what affect it would have on my big coil's Q when placed the damp smaller
tube inside it. The outer paper was just damp as this stuff does not absorb
water real well.
With the small tube dry I got a Q of 38.4 which is about half of my regular
coil's Q.
With the small tube damp... I could not measure the Q! It was far too low to
take any real measurement. Apparently, only a little water in these tubes will
completely devastated the Q!!
I must seriously now question using Sonotube/Quik-Tube in damp environments!!
However, perhaps drying and sealing will make it more resistant to water?
This would probably make one great humidity measuring device!
Cheers,
Terry
