ICE 419B Bandpass Filters
I have been kindly given quite a bit of gear to take over the care off, and part of this was 2 Band Pass Filters from a very good friend, who I am ever so grateful to.
The only time I have ever seen these before was when I was in Germany and the odd photo of a big contest station.
I have in the past used the normal Drake or Kenwood ones that fly around the second-hand markets and can normally be picked up for less than a fiver from those less greedy gits that are out there, and a few have been OK, but nothing to write home about, if anyone has ever found any of these that are very good then I would be interested in knowing the make and model.
These two units are a bit different though, and a little bit special. I have often seen these around, mainly on those big stations that do a lot of contesting and I never thought that I would see these up close at all.
But here they are, and as I have been told that these should be working and looking at the condition I can believe it, but I suppose that I should look just in case, it is not as if I have enough blummin projects on the go in this even getting smaller workshop.
The Measurements
OK I actually cheated here, Tobias Wellnitz (DH1TW) seems to be the only person that I can find that did a really good review of these Band Pass Filters, and I just copied the screenshots from his Spectrum Analyzer, I will update these later with some nice High-Resolution images, but I kind of gave mine away to a good source and therefore I am at present without one, so for not these will have to do, but anyway please check out his sight at the link above.

What I desperately would like.
A Manual, or whatever this was sold with, I take it there was a schematic, and maybe a best uses guide, but if anyone has one of these hidden away I would love to get hold of a copy and I would be very grateful.
