gokje, de Philips elco's (en torren?) in acht genomen:

Sailor HF SSB /CW Transmitter and receiver
2 x 4cx250B PA (Class AB1 Wideband linear amplifier)
400W PEP SSB / CW out
Synthesised Transmitter, marine frequencies only.
Synthesized Receiver general coverage.

Maar die heeft 2 stuks 4cx; de andere die ik trof:

Redifon RMT1500 Hybrid synthesized transmitter
4x 4CX250B PA (Class AB1 linear amplifier) Wideband solid state exciter.
410 – 525 KHz 800 Watts out CW, MCW (low level mod)
2 MHz R/T 400 Watts PEP out AM (Low level mod) / SSB (Power reduction)
4 – 22 MHz 1.5 Kw PEP out SSB R/T
1.2 Kw out CW
powered by 440v 3 phase AC
