200:8 Ω 200mW Audio Transformers [ PRI and SEC are Center Tapped ] Great for Audio Amplifier / Interface / Coupling / Isolation applications. You get (4) pieces (2 lots of 2) for $8.50 for parts, plus S/H. This transformer is typically used to match a push-pull transistor output to an 8 Ω speaker but it works great for coupling / electrical isolation and interfacing computer sound cards to radios. Connect your SW receiver or HAM transceiver to your computer sound card I/O ports to receive and transmit SSTV, RTTY, CW, sound clips, etc. Click here for a typical interface circuit. * Computer / Ham or SW Radio / Phone Interface * 200mW Audio Power Amplifier / Oscillator * Balanced <> Unbalanced Conversion * QRP Modulation Transformer (click here) Using your computer for Slow Scan TV, RTTY Safely interface your HAM / Shortwave Radio to your Computer Sound Card Input / Output for receiving and transmitting SSTV, RTTY, CW, sound clips, etc. The passive interface carries only low level audio signals. There are some really nice FREEWARE programs that do an exceptional job converting received audio to video, RTTY or Morse code and vice-versa. Google "MMSSTV' and MMTTY' for a couple of the best free downloads available anywhere. Makes an inexpensive but very rewarding project for HAM or SWL experimenters. Dimensions, roughly 0.6 x 0.7 x 0.8 inch cube. Both windings are Center Tapped.
