Bill, Your "cc" to [email protected] did not show on what I perceive as your original post, so you may want to send something separate. OTOH, since you are in a bit of a hurry (laving on Friday), and support has to wade through the entire weekend's worth of email, you may do better to phone 831/763-4211 first thing (8AM) California time - well, leave enough time for Dale and Howard to settle down to their work positions and have a few sips of thier morning beverage.
In the meantime, check the obvious - remove the APP from the back of the K3 and check the voltage with your DMM - there is a possibility that there is a problem with the DC power cable. If you assembled that power cable, take a look at the end of it - the blades of the connectors must be clipped securely over the spring fingers in the housing. If you need a diagram of how it should look, check figure 29 on page 37 of the XV transverter assembly manual - http://www.elecraft.com/manual/Assembly%20Manual%20XV50,144,%20222%20Rev%20D.pdf 73, Don W3FPR On 7/29/2012 7:48 PM, Dr. William J.
