Request with help/specs for a Globe Chief 90 coil --

[Jim and Karen]

Hello Mike.  My Globe Chief 90 has that coil missing, nothing connected 
to Ant 2.  I have the manual for the Globe Scout Model 65 that has the 
same circuit and uses a L-4.  It is listed as 20 turns of B&W #3016.  
The Globe Scout uses a 6146 and the Globe Chief uses a pair of 807's so 
that may make some difference in the coil.  The pictorial of the Globe 
Chief shows L-4 as fairly large coil.  I don't have the diameter of the 
#3016 coil stock at hand right now.  Hope this helps some.
73, Jim
