One solution that I think is a worthy idea is to remove the speaker from the K3 permanently. This should allow more room inside the K3 for future little add-on things that Wayne and Eric might come up with.
Then, a small external speaker in a nice matching enclosure could be sold as a "kit" separately. Not all of us would need it. I have a nice external speaker now that I would use on my forthcoming K3. I mean, who uses the built in speaker anyway. If you are operating portable then very likely (since you might be outdoors at a campsite for example) you would use headphones anyway. phil, K7PEH On Dec 22, 2009, at 8:06 AM, [email protected] wrote: > I became aware of the problem last summer while in Maine.
