[Elecraft] Auto Bandpass Filter (sorry sent too soon)

[Pete Smith]

I ran 2 Dunestar 600s for 3 years with no problems in contest service.  
They are very well built, and the support is fine.  ICE can be very hard 
to get ahold of, but a lot of contesters use the 419B without notable 
trouble, so far as I know.

The W3NQN filters that Array Solutions uses are definitely superior to 
the filters in the other units, but you pay for the privilege, and 
whether they are worth it is moot, so far as I am concerned.  I think 
I'd prefer to go with the Dunestars and add stubs to deal with 
troublesome combinations of bands (keeping 40 out of my 20 meter RX was 
always hard for me).

I think you'll find that all of these units rely on switching voltages 
provided by band decoders, so that's another piece of hardware you would 
need as an intermediary between your radio or computer and the BPFs.
