We are pleased to announce that Bob Brehm, AK6R, Chief Engineer of Palomar Engineers will be our special guest presenter at the April 1 meeting.

Bob has been a ham for over 50 years with experience in contesting, RTTY, Amplitude Modulation, vintage radio restoration, boat anchors, linear amps and unique antennas. He is active on 3.870 AM and 3.895 Vintage SSB, the Saturday swap net on 7.240 as well as other nets offering his expertise to new and old hams alike.

Bob will be presenting on the ABC’s of RFI for Hams

Is your transmitter the SOURCE of RFI affecting electronic devices in your own house or your neighbor’s house?  Would you like to find a quick and easy solution so you can have more time to operate and enjoy ham radio rather than troubleshooting RFI issues?

Are you the VICTIM of RFI from your own electronic devices or from devices in your neighborhood? Do you want to reduce your receiver noise floor so you can hear local contacts and more DX?

If you answered YES to either of these questions, then you should attend this presentation where you will learn how to make ham radio more enjoyable by eliminating problems caused by RFI.

Topics will include:

  • Learn fundamentals of RFI – identify symptoms, pinpoint causes & apply simple cures
  • What’s a ferrite and how to choose & buy the right ferrite for your RFI issue
  • How to use ferrites to solve the #1 RFI problem shared by all hams using HF radios
  • How to choose and use ferrites to solve transmitter RFI problems in your home or neighborhood
  • How to choose and use ferrites to reduce receiver noise and hear more DX

During the presentation you will see many examples of feed line chokes, baluns, ununs, and various practical applications of ferrites for AC/DC power lines, computer interconnect cables, transceivers, linear amplifiers, home theater systems, etc.
