Jim K9YC was most helpful with my question on using the Titan 425 with the K3: "I have three 425s, and have used them in contesting for years using this arrangement, which was a way of doing QSK with virtually any rig (the 425 was designed before 1980). You do NOT need to do this with the K3 -- the K3 has a built in TX delay (adjustable in CONFIG) so that the TX/RX relay in the amp has time to switch. So simply set the 425 in PTT mode and feed it the amp keying line from the K3. I'm conservative, so I set the delay for 12ms to give the relay plenty of time to switch. The default is 8ms. ------------------------------------- And Mike AC5P offered the same kind of good suggestion: "Gary, The one thing different about the K3 is the DC power input connector. This is an Anderson 30A Power Pole connector. I don´t know of any other ham gear that uses this type of connector. IMHO, it is superior to the Molex type plug/jacks that the others supply. They supply one (and one only) connector and 6 ft of #12 DC zip cord. Most hams don´t have the special crimp tool, so you will have to solder the pins correctly positioned THE FIRST TIME to make it up." ------------------------------------- As to the Amp, I'll be sure to read up on how to find the delay in config. Last time I modified anything with "config" was back with windoze 95 :) I'm sure that config / setup will be something I will be using a fair amount at first & probably when I update and the like. As to the Power Pole connector, this will be my introduction to them, never seen one before. Thus far I've been a dinosaur when it comes to new ham gear & my newest anything is 20 years old till now with the exception of my K9AY sold by Array and my Ameritron coax switch. Wait, I do have a butternut I use for 40 & up that was made in the mid 90's... :} Any other suggestions regarding a heads up perhaps regarding specialty assembly/test equipment I will need to be ready for the k3 100W kit?
