Hi Wayne, A while back I found a used Roland Mobile Cube stereo amplified portable speaker set at the TRW swap meet ($5) and to my surprise it works pretty well as a laptop amp, portable PA (mic needed), or as a mono or stereo amp for just about any mic or line level driver (including radios like the K3). Take a look at; < http://www.rolandus.com/products/productdetails.php?ProductId=957&ParentId=4 20>
They're often available new and used on Ebay. The 1/8" stereo phone plug input (AUX input) has no level control so the volume must be controlled by the source. Another solution is to use an adapter cable and feed the main mono or stereo inputs (Amazon, CMP153, $5). This port not only offers level control but also has some special effects available. The Mobile Cube runs on either 6 AA batteries or an external 9Vdc source. 73, Gary N6LRV -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Wayne Burdick Sent: Thursday, December 29, 2011 9:51 PM To: [email protected]; Elecraft Reflector Subject: [Elecraft] Looking for KX3 external speaker suggestions Hi all, Those of you who have seen the KX3 in person may have noticed that we use it with two external powered speakers, plugged into the headphone jack. We do this to emphasize how good the KX3's stereo audio effects are. (And of course it's so noisy at most hamfests that the small [but hi-fi] internal speaker can't be easily heard; it's intended for a use in a quiet shack.) Audio effects include simulated stereo, left-right pitch mapping, and dual-watch. These can only be heard with two speakers or when using stereo headphones/earbuds. Trust me, you'll never go back to mono :) We've tried a couple of different Sony powered mini-speakers from Best Buy. Both had batteries but could also run on external power either from a PC USB port or from a small power adapter. If you have some favorite small speakers you've used with a laptop or other radios, please send me the manufacturer and model numbers. Small is OK as long as the sound quality is good. Also, they shouldn't cause RFI. For mobile--another very high-noise situation--you'll have three alternatives for getting car-filling audio: 12-V powered speakers, a modulator to rebroadcast the KX3's audio on an FM radio, or (my favorite) a stereo aux input to the vehicle's audio system. The latter is very common on newer models. If you know of some decent 12-V powered speakers, please let me know. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] 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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
