[BC] RE: Energy Onix AM Transmitters

[Dave Cooper]

I would talk with either BE or Wayne or Sinan (hope I spelled that right) at
Armstrong.  I have two of the 1kW solid state two module boxes.  I just put
one in service on KZZZ and the other has been in service over a year on KFLG
AM 1000.  Both have been solid performers so far and the price point is
quite "competitive!"  But, I have a BE that I really like as well.  The AM1A
is a good box.  Buy the surge suppressor if you go BE.

Scott:

My gut instinct would be to go with either a BE or Armstrong kilowatt AM
transmitter.

Our former AM uses a BE, and i talk with their chief from time to time.  The
problem with the BE is that it uses a transformer-less power supply.  Hence
the power supply has no isolation from any spikes coming down the power line
during storms (or having a hv distribution line short over into the 11 kv.
feeder, which has much the same effect as lightning on the poor
transmitter).

So you really need surge protection for those times when Mother Nature and
her husband Thor have a knock-down dragout upstairs & start smashing the
china.  I would be inclined to install a 1:1 transformer on the incoming AC.

I haven't had much exposure to the Armstrong AM transmitter, but I have an
Armstrong FM exciter.  Their service seems to be good, and the company has a
good reputation. The price point also is pretty good.
