[Amps] Plate Choke Resonances

Hello All,
I just finished winding a homebrew Ameritron-copy plate choke using the 
details provided by Carl.  Thanks to Carl's patience and magnifying 
glass.  Shorting the choke and with a grid dip meter, I observe 
resonances at 14.380MHz, 18.200MHz, and 41.5MHz.  I assume that the 
resonance at 14380 will be problematic, or will the resonance shift far 
enough away once the choke is installed?  Experience please.  Thanks & 
73, Tim, W2UI
