Hello Claudio Tagliabue Nice story..

Many Thanks for your Message at Moonair DX Radio. from Germany.

 

Some info about my transmitter.

Former historic medium wave transmitter of the church station "Radio Bloemendaal" from the years 1979-95 from the Netherlands. Originally it was the transmitter type "Philips SFZ395", which was converted into a 50 watt radio transmitter. This tube transmitter was decommissioned after the medium wave broadcasts from Bloemendaal ended, and this transmitter was sold. And now after years of standing in dark basement, this original transmitter tower has landed at Moonair.

The entire SFZ395 transmitter is built into a 19" cabinet containing the power supply, modulator, exciter and power amplifier. It is on casters so it can be moved as well.
The transmitter is quartz-controlled (groundwave) and can be tuned in the range of about 1000 ... 1650 kHz. The original crystal Frequency is 1116 kHz. The tubes are E80L in the preamplifiers and QQE 06/40 in the modulator and HF power amplifier. Output power approx. 80 watts carrier at the coax antenna connection and ++400 watts PEP.. There is a second transmitter slot in the cabinet for continuous AM operation, but this serves only as additional amplification, connected in parallel to the existing power supply unit for continuous operation.

My shortwave Transmitter is the reserve transmitters from Radio Bloemendaal !! it is also a Philips SFZ395/000 but modifiet by my selve !! carier is about 150watt and pep he gave a 600 watt at 4950 Khz. i use a Invertet V antenna to bring my transmission power over europe! 

The whole is for (230V ~ / 1 Ph mains input, input about 500 watts) In the lower part of the cabinet is the mains connection, the connection panel for modulation with NF isolation transformers and then the additional power supply and the transmitter/modulator chassis. A fan unit is installed in the upper part of the cabinet.,  the stereo coder part is not in the cabinet but seperated from the transmitter! i build my selve !!
