Subject: [alt-beam] Re: Unicore BeamAnt schematic!


I don't quite understand the logic in using a M/S bicore either but everything
I've seen says that the BEAM Ant 6.X uses an embedded bicore and Nu's to achieve
the exclusive OR function. Their worth may be proven after I start
experimenting with the circuit. The extra stages most likely provide increased
"programmability".

BTW. Judging from pictures available on-line of the BEAM Ant 6.X there are 6 or
8 programming resistors which corresponds nicely with the posted schematic.

Either way, I'll try both methods and see which is better.

PS. Where's that schematic Ian? You can't drop a bomb like that, then leave
all of us hangin'! ;)
