FM Exciters Transmitters Processors PCs and IT Misc Equip 


 OMB is a Spanish transmitter manufacturer with a small USA footprint.  Every once in a while I come across a piece of their equipment.  Today is one of those days. \ …this looks an awful lot like an RVR TEX-100.  […]


      Here we go again, Symetrix 528E mike Processors.  Some noisy, some non-functional. Let’s pick one and see what we can find.                                  […]
