[Elecraft] K3 & Bose speakers

[Tom Fitzgerald]

"What's the opinion on BOSE COMPANION 2 SERIES III MULTIMEDIA Speakers for use with K3 or KX3?"

You WILL experience RF getting into them on the upper bands. They sound good and function well on the lower bands (75 & 160) but as you move up to the higher bands...key that mike and begin to transmit, you will hear it getting into those speakers. This happens with most amplified "computer speakers" and or surround sound type speakers. I've had Bose speakers connected to my K3 for several years now and I either switch radios (I have 3 to choose from) that use different speakers or I bypass the Bose speakers (shut them off completely with the "master switch" on the subwoofer) and use headphones on the upper bands if I stay with the K3. It's the speakers and not the K3, they (the speakers) are not shielded. You will need to switch (power) off the speaker system completely to avoid the RF issue. I've noticed RF getting into them even when they weren't being used unless that master switch is off and the speakers are no longer being powered. I do have a couple of amps that make the problem worse but I notice it even with only 100w output.
