Maybe Gamma Research's HPS-1a at http://www.gammaresearch.net/hps-1a.html will meet your needs.
It's 3.37" x 1.55 x 5.25", specified to provide 5A continuous and 22A at a 25% duty cycle. It weighs 1.25 pounds (which probably doesn't include the line cord) I have one for my K3, and it works acceptably on CW, but I wouldn't use it for a RTTY contest. I recall that it has about a 5 Farad output capacitance and the caps are operated very close to their rated limit. My recollection may be fuzzy. Their web site shows "temporarily out of stock" and to expect a delay after placing an order. Perhaps one of your employees might loan his if you can't get one in time. 73 de Dick, K6KR On Jul 4, 2011, at 2:23 PM, Wayne Burdick wrote: > I'm going to take a KX3 with me on vacation this summer, and I like to > travel light.
