Of course, the design is NOT limited to 80m. Excellent results produced 
the BN73-202 binoculars for T1-T4 (2 turns where the schematic requires 
4 uH, 4 turns for 16 u). Not tested the amp with small signal bipolars, 
used my ~12 dB amp with 2N5109 and excessive input filtering (LP in 
series with HP) similar to K9AY 
(http://www.aytechnologies.com/TechData/FilterPreamp_160-80.pdf).

The MFJ design is definitely not a succesful attempt, W8JI tell why...
