Hi DW: You asked:
"I do not have the K60XV. It says that the Transverter turns on when the Band+ or the Band- are selected. I assume this means the XV50 will turn on when 10 meters is selected with the K2?" No. After doing the setup with your K2, your K2 will now have a 50 MHz band in the BAND rotation. When the 50 MHz band is selected, your XV50 is activated. When 10 meters (28 MHz) is selected, the XV50 will NOT be active. That's all set up with the TRN items in the MENU as described in the manuals. You can actually have separate XV40, XV144, XV222 and XV432 transverters all daisy-chained on your K2 and the K2 will then show the 50, 144, 222 and 432 MHz bands in the BAND switch rotation. You asked: "The manual stated not to use an antenna relay to switch between an HF and the 6 Meter antenna? I guess this also includes a manual antenna switch which are more lossy than a good quality antenna relay? What option is left, unscrewing the antenna at the back of the K2 when operating HF?" The problem with an antenna relay is isolation, and manual says. Most relays aren't very good, especially at 28 MHz. So, even though the K2 is feeding power to the transverter, enough RF is usually coupled to the 10 meter HF antenna to radiate significant signal. The challenge is to find a relay or switch with adequate isolation. Otherwise, you are left to swap antenna cables (which does provide good isolation!) unless you use the K60XV. That's one of the major reasons for providing the K60XV interface. When using the K60XV interface, no RF is generated at the K2 ANT connector on the VHF bands. When using the KAT100, the switch or whatever you use to direct RF to the transverter, goes between the K2/100 and the KAT100. When driving a transverter, the K2 is running at only a few watts to drive it, even if it is equipped with the 100 watt amplifier.

My XV50 is almost built. I have not put power to it yet. Reading the Owners Manual I don't really understand the best way to hook up both an HF and a 6 Meter antenna. I do not have the K60XV. It says that the Transverter turns on when the Band+ or the Band- are selected. I assume this means the XV50 will turn on when 10 meters is selected with the K2? What If I wanted to operate 10 Meters? Do I turn the XV50 off manually? The manual stated not to use an antenna relay to switch between an HF and the 6 Meter antenna? I guess this also includes a manual antenna switch which are more lossy than a good quality antenna relay? What option is left, unscrewing the antenna at the back of the K2 when operating HF? How are some others using the XV50 with a K2. I'm also going to wire in a KAT100 and my K2 has the 100 watt option. Thank you in advance for any help.
