Transmitters

Our nice Telefunken S2525/3 AM broadcast transmitter

We used the Telefunken S2525/3 very often on the Shortwave 48m. it’s a great transmitter with a very nice audio quality. This HF broadcast transmitter is fully solid-state up until the final power amplifier. The S2525/3 has the following specifications: 1 Kilowatt continuous output power; solid-state (except final stage YL-1510); covers 1.5 – 30 Mhz, synthesized,10 Hz resolution.

Refurbished Rhode & Schwarz SK080

Rhode & Schwarz SK080 AM broadcast transmitter with classic anode/screen modulation, built in 1959. 100% tube-based, 800 watts RF, sucks 3.4 kVA (one phase!). Radio Delta engineers refurbished this beautiful vintage transmitter. The R&S SK080 has a nice internal modulator with 2 x QB3/300 tubes. The R&S SK080 could modulate around 800 watt nom. https://youtu.be/Q4twJnfqxwMhttps://youtu.be/FCuQITyQfv0
