[HBR] WARC bands?

[B. Smith]

       First build a working receiver. The experience gained from 
fabricating coils for 40 meters  will help you with the WARC bands. Take 
your 40 meter coil that you made and  compute  the change in frequency 
from 40 to 30 meters as a percentage. Use this percentage and apply to 
your 40 meter coil windings  to compute turns for 30 meters.  It won't 
be perfect the first time but its not that hard and it fun.   The good 
news is the band spread for the WARC bands  is only 100 khz and that 
will be a piece of cake compared to 300 Khz for 40 meters.   :-)
And it can be done  it in the opposite direction with 160 meter coils 
for the HBR.

I'm still in the process of building my HBR-13 and my plan is to calculate the inductance of the coil for a band close by, then translate that to the WARC frequency, then wind a coil from that data,  and see if it works. If I do it first, I'll publish it here.  If you do it first, please publish here.
