I dug up an old spec. sheet for the above 220 MHz duplexer in the shack today. Wondering if this sheet was available on the web somewhere (so I could throw it away - cleaning up), I did find it on Repeater-Builder at <http://www.repeater-builder.com/wacom/wp652.pdf> However, there are some distinct differences between the two data sheets, the PDF sheet having a date of 3/97 & my old sheet of 9/85:
old sheet: 220-300 MHz, 1.0 MHz min. spacing, 350 watts max. new sheet: 210-260 MHz, 1.0 MHz min. spacing, 200 watts max. The frequency response charts look identical, as do the loss & isolation specs. The old sheet lists the finish as gray enamel, while the new ones are black enamel. Guess they really don't make them like they used to. Bob NO6B P.S.: I'm hanging on to the old sheet; when I get some time I'll scan it & send it in to Mike for posting to the R.B. page.
