If your TS-2000 is capable of generating RF output at 10.000MHz, you
now have your own BUILT-IN WWV!!! Turn the POWER on the TS-2000 to
ZERO or as far down as it can go. Set the TS-2000 to TX (AM mode if
available) on 10.000.00 MHz. Transmit into a dummyload, and you're
good to go! Follow the docs for aligning to WWV at 10MHz.
If that doesn't work, but IF the TS-2000 offers a 100kHz (or 1MHz)
xtal cal. use it as a sign gen, with a short 'sense' antenna
connected to the K2 and capacitively coupled to the TS-2000's ANT
jack (should be enough for the K2 to hear the xtal calib. Still a
source of accurate 10MHz signal.
