Sorry - same guy, different company. TopTen was what I meant. W2VJN
was responsible for the design of their 6-way relay box. The ones W2VJN
used in the antenna switch are Schrack RTD 14012. See
<http://www.mouser.com/Search/ProductDetail.aspx?qs=CNrsY6Bml5lyPTnKwpMBZw%3D%3D>.
$2.34 in onesie quantities.
I misstated a couple of specs - they rate their relay boxes for 1 KW
RTTY to 30 MHz at swr of <1.5:1. George told me he had tested to 3:1,
so I suppose he was just being conservative.
