Inovonics 222 does the asymetrical modulation (positive peaks) you need to expand you part 15 AM coverage. Highly recommended by Keith Hamilton & the Rangemaster folks. I used it at WZFB in Fair Bluff (full power licensed station) when I owned it and then used it to drive 3 hamilton Rangemasters to create the part 15 legend Surfside 1640 in Myrtle Beach, SC. The AM broadcast has since been shut off due to our success with iTunes & Roku and it is time to say goodbye to my trusty old friend.
Might be a dirty pot, loose connector or so... but it powered up nicely and this bad boy got my 1000 watt AM to reach Myrtle Beach, SC from Fair Bluff, NC (40 or so air miles) at 1/3 power. Nothing a little techy TLC couldn't handle. This things a gem...truly an audio "Rangemaster" of sorts.
Hate to see it go and have been really torn about selling it. But, I guess now's the time.

**More goodies will be up for grabs as well. I also have an Aural Exciter with Big Bottom that I used and a BBE Sonic Maximizer that helped with the bottom end of our awesome AM sound; also increasing coverage. Can sell it here or on Ebay. Let me know if you are interested. [email protected]
Now the legalities: All items we sell have no warranty of any kind, expressed or implied, and are sold as is. Beyond a power-on test, we conduct no other tests or measurements.
From Inovonics:
"The 222 was originally developed as a ‘post-processor’ to ensure US broadcasters’ compliance with FCC-mandated occupied-bandwidth regulations. It incorporates a fast, asymmetrical peak limiter, independent pre-emphasis-protection limiting, and a very sharp-cutoff low-pass filter with proprietary overshoot control.
The 222 finds ready application in a wide variety of AM broadcast situations. In addition to the NRSC 10kHz cutoff for medium-wave AM broadcasting in the US, any high-frequency protection characteristic between 4.5kHz and 15kHz can readily be accommodated to meet other domestic and overseas needs. Though the 222 is intended to provide basic final limiting, a ‘floating platform’ release characteristic yields sufficient program dynamics compression that often the unit can be run ‘barefoot’ between the console and transmitter with good results."
