Marcus has worked with Ortovox for years, and seen it all.
Editor’s note: Our in-house beacon expert Jonathan Shefftz found what he considered to be an issue with his new Ortovox 3+ when he updated his review last week. Below, Marcus Peterson of Ortovox North America responds in what I feel is a very thorough and thoughtful way. If you’re new to this, please read Jonathan’s post before you read below. Otherwise, have at it. (And thanks Marcus, for taking the time to work this.)
Lou and WildSnow readers, thanks for the opportunity to contribute to the discussion.
I would like to preface my remarks by saying that I have known Jonathan Shefftz for several years and have always found him to be conscientious and of the highest integrity.
Regarding Jonathan’s comments on How Well It Works… on the recent Ortovox 3+ blog post and thread, my thoughts focus on Electro Magnetic Interference (EMI).
Page 26 of the 3+ Owner’s Manual affirms that the 3+ complies with Part 15 of the FCC Operation Rules. Specifically: (1) the device may not cause harmful interference, and (2) the device must accept any interference received, including interference that may cause undesired operation. This is a requirement of every transceiver sold into the U.S.A.
Luckily, most rescues and recoveries are performed in remote areas where EMI is not a factor. Practice sessions and beacon drills in an urban setting are a completely different matter. To insure a “quiet” practice site, it is recommended that (if available) one use an older analog beacon to provide a baseline for your practice site and help identify suitable practice sites. Switch it to “receive”, adjust the manual volume control to the highest setting and listen to the amount of “crackling” noise (EMI) heard, paying special attention to whether or not the crackling is concentrated in a specific area.
