Title: Schlockwood 200 audio processor Post by: VE3AJM on June 26, 2019, 10:52:33 AM 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 $$$.

(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. Rod KQ6F Title: Re: Schlockwood 200 audio processor Post by: VE3AJM on August 02, 2019, 11:52:41 AM Thanks very much for letting me know. I may purchase one.

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." |
