Stephen Lockwood of Hatfield & Dawson Consulting Engineers has set up two listservs on the Society of Broadcast Engineers (SBE) Chapter 16 server to help shortwave transmitter users.
According to the National Association of Shortwave Broadcasters (NASB), the listservs are forums for suggestions for maintenance and operation of Continental 418 and Harris SW 100 transmitters, although listservs for other makes and models may be added.
