Question:  I have a legacy UPX-10 wireless IFB transmitter and RCV-2 receivers that is used in a hearing assisted environment.  I'm looking for used receivers to augment the system, I found a similar receiver called a PL-2 manufactured by a company called Vega Wireless that produced wireless products in the 1990s.  Are they the same product with different names?  Please let me know. 
Answer:  The PL-2 receiver made by Vega wireless and the RCV-2 that was sold by Clear-Com Communications are one in the same product with the only difference being the front panel face plate.  Vega wireless supplied Clear-Com with the PL-2 receiver as an OEM manufacturer and the product was rebranded the RCV-2 for use with Clear-Com's Pro Party-line product.  The RCV-2 was paired with the UPX-10 wireless transmitter to form a wireless IFB system.  The UPX-10 / RCV-2 system was obsoleted in 2006 and replaced by the PTX-3 / PRC-2 UHF wireless IFB system.
