Appears to be MILSPEC. > 73 Walt (N4GL)(352) 637-1755 4 coax connectors probably means its a transfer switch. I didn't find that number in my Amphenol catalogs, where part numbers tended to have a 310- prefix and all numbers, no letters, so it may have been a custom special or from a different era. I don't see evidence Amphenol staok RF relays were rated for more than 1 or 2 GHz. 73, Jerry, K0CQ > > > From microwave at mailman.qth.net Tue Oct 7 12:26:26 2014 From: microwave at mailman.qth.net (Walter Treftz via Microwave) Date: Tue, 7 Oct 2014 16:26:26 +0000 (UTC) Subject: [Microwave] FS: 50-Ohm coax terminators Message-ID: <2110453357.648953.1412699186344.JavaMail.yahoo@jws100156.mail.ne1.yahoo.com> >From estate of retired microwave engineer.
