Final transistor mfr 455 x 4. These are controlled by powerful microprocessor that can identify all possible fault conditions and alert the operator both on error tone and error message on LCD display.
For operation the pa requires 13. Power voltage 13 cc 2v. This will afford the contest operator a much quieter noise level the new Rm Italy hla 305 is a wide band compact amplifier for the hf band covering from And more.
This has significantly improved the attenuation of the harmonic output. New features include larger heat sink a new die has been designed that provides increased dissipation by about 25, which in turn increases the internal PCB size allowing improved layout of some of the critical circuit components. Dimensions 240 x70x 450mm. 160m to 10 m the classic Rm hla 300 series still a very good amp.
There are 6 filters built in to suppress harmonics, which are switched automatically but can also be switched manually for special operating conditions. The hla 305V has an oversized heat sink and therefore remains cool during operation. This allows the amplifier to be used at higher duty cycles without the requirement for cooling fans.
And its output power is 250w, with an input power of 1 10 watt. More linear input circuit this improves the measurement of both frequency and input power. Also in Italian am FM cw Sb average power gain 13,5 1db p1db.
