It will eventually hang from an old Atlas BS-37 boom stand and travel through a Collins 26W limiting compressor, 116F passive equalizer, and 212A console before entering the 300G transmitter. It'll likely need a preamp added after the equalizer too, which is really just an attenuator. Unlike most amateur transmitters, broadcast mics and transmitters pretty much require the use of some outboard processing. OTOH, the audio coming out of a KW-1 will remain limited by design without some major reworking. Be it a new audio driver circuit using 4 tubes vs. 2, stiffer mod iron, or the age-old component modifications. Trying to run outboard processing as-is will more likely add to the feeling of it really being 'outboard distortion'. Rather than trying to make it into something it was never intended to be (a broadcast transmitter), I found it easier to do the simple component mods including bypassing the clipper and splatter filter circuits, enjoy it as-is, and get the 300G for the broadcast experience. You can really go wild with some of the old amateur gear with outboard mod iron and the rest. It really gets down to what you like, what you expect from it, and how much room you have. Simply following Jay's article in ER makes the KW-1 sound really nice, though without major surgery, it will never modulate like a custom-built homebrew or broadcast rig. ~ Todd, KA1KAQ/4 ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/[email protected]/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: [email protected] To unsubscribe, send an email to [email protected] with the word unsubscribe in the message body.
