[Lowfer] My variometer resistance

Learning as I'm going, My variometer was the single best thing
I have done for my beacon so far, bringing the greatest gain.
It's a 5 gallon paint bucket, wound with very small wire. I'm
not sure of the guage, maybe #28 to #30 ( 6 stranded solid
burglar alarm wire ). I know small wire has higher resistance,
So I thought it would take fewer turns for a needed inductance.
I measure 9.0 OHMs DC resistance across the variometer, and I am
assuming that's way too high, and have been told by others they
thought it was pretty high. If this question can even be asked
this way; " What is a TYPICAL DC resistance of a paint bucket
variometer ?? " I do consider wire size, material, spacing, etc.
In the how bad do you want it catagory, the current cost of a
500' rool of #14 solid / insulated is around $ 45.00. That's one
reason I used the wire I had on hand for free. Still choking on
the $ 45.00 wire.
Nutshell:: Is 9 OHMs too high ? Is there any such thing as typical ?
