The BE STX 10

We just finished installing one of these units on Mount Beacon for WSPK. Mount Beacon is around 1,500 feet high and is accessed by a road which is a little bit rough. After the snow flies, the only way to get there is a snow machine or perhaps a helicopter. Thus, whatever is installed there needs to be reliable.

My first comment, I recall 10 KW FM transmitters being much larger. This unit is pretty compact and we probably could have fit two of them in this Mid Atlantic rack had we wanted to.

The transmitter itself is pretty simple, four RF modules powered by seven OEM switching power supplies with two fan power supplies, one for each fan unit. This is driven and controlled by a STXe 500 watt exciter.

The back has a 1 5/8 inch EIA flange output, some power connections, remote control interface, etc. Pretty simple overall.

I can also say, there was a noticeable improvement in the audio quality when this was placed in service.

  1. Welcome back to the radio side of posting, of course you were missed!
    What became of the Nautel you installed here a few years ago and why?

  2. Paul,

    Are you feeding that beast single or three-phase power?

    I have a client with an open-delta service and the options for a new solid-state rig so far are to go to single-phase or pay $$$ for running 2 miles of wire and another pole pig to close the delta (or change to wye)…or void the warranty and take their chances with open-delta 3-phase, which I don’t want to do.

  3. This site has three phase power, so it is three phase. You should contact BE because I think these are capable of single phase as well. The manual is a little ambiguous. Don’t do open delta.

  4. I definitely want to get away from open delta. I’m surprised there haven’t been more issues at this site with the HT-10 that’s there now.
