Has anyone on the forum used or had any experience using this processor. Its geared to the LPAM/community radio market.

Wondering about RF getting into it in proximity to a higher power AM transmitter. Molded case, and is there any bypassing etc to minimize RF susceptibility. Otherwise, it looks like good value for the $$$.

I use it with my homebrewed Class D/E AM transmitter which is packaged in a plastic clam-shell box with no internal shielding.  (there's a picture of it on my QRZ page).  I have the Schlockwood sitting directly on top of the transmitter and have experienced no RFI problems nor any other problems.  I will say this about the Schlockwood...it has several features a couple of which I found unnecessary for ham radio.  I have disabled both the auto AGC and the Pre-emphasis.  The auto AGC is intended to compensate for varying audio levels from different sources and for close talking vs talking away from the mic.  I don't do that.  Regarding the pre-emphasis, I just don't like how it sounds.

Otherwise, I like the Schlockwood and firmly recommend its use.  And its developer, Jim Wood, is a helluva nice guy.

Beautiful workmanship, Rod.

Al, I looked at the Schlockwood 200 for my K7DYY 80/40 Super Senior, but decided to go with an Inovonics 223 from BSW's B stock. Frankly it was  a lot more money, even with the B stock savings (because I got the Inovonics 223 rack mount). Besides the usual audio processing attributes, I liked the 3 band look-ahead limiter, positive / negative peaks meter and the 223's ability to police the bandwidth of my signal to within legal limits. Janis, AB2RA, calls the 223 the "poor girl's Optimod."
