TopBand: Front End Filters

[jmaass@freenet.columbus.oh.us (Jeffrey Maass)]

Is there a current source for narrow crystal front end filters, like the ones
Sherwood marketed in the late 70's? For 160M, they were 5KHz wide,
selected by center frequency. 

I don't see mention of them in the current Sherwood literature.
