Jeff Glass notes: "When I first got
here, the transmitter had an incredible appetite for PA modules. Failure
at the rate of one per month. After some parameter optimization done by
me, internal cooling improvements by QEI, and upgrading the HVAC system,
the last module failure was two years after the above improvements. The transmitter is elegantly simple. The control circuit can easily be drawn on an 8 X 11 sheet of paper. The transmitter can be worked on with little if any pre-disassembly work. All modules and subassemblies can be easily repaired in the field. The only unhandy characteristics of the
transmitter are that the exciter is an integrated unit to the transmitter.
The exciter is also the IPA. [However] the IPA/Exciter assembly is built
such that by removing a jumper in the back of the unit, it is possible to
feed the IPA portion with a more standard exciter, should the QEI exciter
itself should fail. |
