>From the Repeater-Builder website: "WACOM and Remec
WACOM started out as Waco Communications in Waco, Texas. At some point WACOM was bought by Remec, and in November of 2001 was sold to TX-RX." TX-RX has since been purchased by Bird Technologies Group. I've tried several times to contact them about some replacement cables, etc. for some used TX/RX VHF Repeater Duplexers, and have received no response except for one reply that said something like "I've passed your request for information to our engineering group, who will be contacting you with the information you need". I never heard nything further, after several months. But several weeks ago, we were able to order a brand-new TX/RX 420-MHz 4-cavity duplexer from Bird Technologies for a 420-MHz link transceiver, although it hasn't arrived yet (it's a "Special Order" item).

Good luck contacting them directly! -----Original Message----- From: Richard Kelly Sent: Sep 8, 2010 9:18 PM To: [email protected] Subject: RE: [Repeater-Builder] Wacom WP-639 Duplexer question Good evening Eric, Maybe this is why when the trasmit power is dropped to the 20-50 watt range, the receive opens way up like it should. However, according to the spec sheets regarding the Wacom SP-639 Duplexer, it is rated for 200 watts. So, again, not sure what's going on. We will be trying other things such as adding a second ground rod outside the shack instead of the single one we use now. We will also try isolating the amp some more and replacing the coax feed line with hard line. Thank you very much. We will be contacting Wacom directly tomorrow. Rich Kelly, W2RRK
