[Elecraft] k160 led

[Sverre Holm (LA3ZA)]

You are referring to my web page on how to fit 5 LEDs to the K2s frontpanel
(http://www.qslnet.de/member/la3za/K2_LEDS.html)

In order to get a wire from the K160RX option to the LED on the front panel
I had to use pin 7 P1 on the RF board. It is used originally for the AUXBUS,
but since it is not used on the Front panel, the pin can be used here
instead. But, _and this is important_, you have to cut the AUXBUS signal
from the pin first. Otherwise the LED and everything else will load the
AUXBUS so that the option boards that are controlled by the bus stop
functioning, just like you have experienced.

The 2 red arrows on the circuit diagram
(http://www.qslnet.de/member/la3za/skjema/K2Leds_sch.pdf) are just the main
plug P1 on the motherboard that mates with J1 on the Frontpanel board.
