[amsat-bb] Diplexer recommendation

[Patrick STODDARD (WD9EWK/VA7EWK)]

Rico,

I had used either Comet or Diamond diplexers in the past, until I
found the MFJ diplexers were about half the price of the Comet and
Diamond units, with what I saw as comparable performance. WiMo in
the US is like your description of MFJ in Europe; I've never seen
or tried WiMo diplexers.

One review I saw a while back actually showed the MFJ-916B to be
much better than Diamond's MX-72:

The pictures and screenshots aren't in this article, but the text
tells the story of this comparison.

73!
