Yes, the Heil Proset Plus with HC-4/HC5 elements can be used with the K3. Yes, the Kenwood adapter is the correct one if you prefer front-panel connection of your microphone to the K3. The Heil adapter is an AD-1 K. It's red, and has an 8-pin Foster plug.
Alternatively, you plug the 1/8" microphone connector from the Heil headset directly into the K3 back panel mic connector, making an adapter unnecessary. However the back panel phone jack is a 1/8" stereo connector, which makes plugging a 1/4" stereo plug a bit unwieldy. Flexible "pigtail" adapters exist, but they're clumsy and rigid adapters 1/4" to 1/8" adapters may stress the 1/8" jack excessively. I ended up with a Heil headset that came with a 1/8" stereo plug for the headphones with an adapter for 1/4" when I need the larger size. 73 de Dick, K6KR -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Terry Sent: Thursday, February 12, 2009 12:56 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] Proset Plus HC-4/HC-5 I apologize if this has been covered but I couldn't find anything in the archives. I currently have the "standard" Pro Set Plus with the HC-4/HC-5 elements and the AD-1Y Yaesu adapter for my FT-990. Two questions: Can the HC-4/HC-5 be used with the K3? Is the Kenwood adapter the correct one? I don't have a K3 yet but seriously considering one. I've never had a new rig and I've certainly never had anything approaching it's capabilities. 73 de Terry KK6T ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
