Armstrong

  Armstrong 100 watt FM Exciter.  Approximately 20 years in service.  Built by RVR in Italy, these units are re-badged by Armstrong, Bext and probably others.  They’re generally very good, until the day they aren’t.    Today is that day.  […]

Gates

  The Harris “Gates” series AM transmitters were produced approximately 1990-2000 and most are still providing good service.  This is a later unit and it’s tripped a fault alarm at the studio after overnight storms.  Let’s take a look!    […]

Marti

    Marti STL 15-C. These were the microwave equivalent of a swiss army knife in the 1990s.  Frequency agile and affordable.   There are still quite a few putting in a day’s work. This one isn’t. Let’s find out why.  […]

OMB

 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.   ..Except   this looks an awful lot like an RVR TEX-100… […]

528E

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

Bext

  Bext LEX25.   These are simple, workhorse exciters. 0-25 watts, VSWR foldback, basic remote control and metering capabilities.  They are fairly good sounding units for their age and design price. This one is 2001 vintage and has no AFC lock. […]

Behringer

  Behringer. No sane person repairs these.   At about $200 brand new and $40-50 used, why would you?  Oh why not. Let’s open it up.                                […]

FX30

I still occasionally get a FX30 exciter with the original snip-to-set frequency selection DIP header (pictured at top). $4  worth of DIP switches and frequency changes become much easier. This one needed a few minor repairs. Let’s dig in!       […]

PC

Most of these Deathstar drives failed young.  This one, installed in Aug 2006, did not.  Still running when it tripped the temp alarm at 13 years service.  Not bad.  And that motherboard has the Bad Capacitor plague!       […]

Directional

What’s more fun than getting a call at sunset, informing you that the AM directional Antenna is out of limits and transmitter has also shut down? Nothing. Nothing at all.  Let’s go see what fun awaits!        At […]
