Nice job Alan! Many hams are now using those inexpensive filters so 
they can share their Beverages among three bands without switching. 
And -- as you noted -- the 160 meter filter does a good job significantly 
reducing the signal level of AM broadcast stations below 1600 kHz.

Hi Frank, I built three sets of your filters for 160, 80 and 40 for my beverage system so that three stations can use any beverage at the same time like we talked about. I live about 8 miles from WFBR in Glen Burnie now transmitting on 1590KHz. I cannot hear them with the filters in! Tnx again.
