REQUIRED CONNECTIONS
Required connections are: RF IN, RF OUT and PTT.
The phono input PTT can be activated by any transceiver with a PTT
cable from the LA-1K to the transceiver (not supplied)
. When PTT is
grounded
TX
is displayed and the LA-1K is ready to transmit.

NOTE:
30M is NOT a separate band on the
LA-1K. When the band voltage drops to
zero, the LA-1K correctly switches to 20M.
This allows operation on the 30M band but
without “
DIRECT KEYING
” due to cable
detection by checking for voltage on ICOM
band data input. 30M is limited to 200W
and ampli er operation is not normally
required on this band.
