Hi, Group,
Can anyone tell me what length of end-fed line works best on 80M using a KX1
with ATU? I'm having a heck of a time trying to find a length that will work
with 80M and 40, 30 and 20. I know the ATU is not really designed to tune
80M effectively. It would be nice to have one antenna to
Tom,
There is no single answer to your question. The real answer is that it
all depends...
The feedline is only part of the antenna system, and the rest of the
answer depends on the remaining parts of the antenna - length of the
radiator - orientation of the radiator - how the radiator is

If you are not adverse to a separate antenna for 80 meters and you have

long radiator and center fed with coax. It should work (and feed
easily) for 80 meters (but is a single band antenna). Ideally, it

Hi Ken and Alexandr:
Yes... BE SURE that all screws securing the front shield (to which the KSYN3 is

by ensuring that all screws are snug... but DO NOT tighten them to the point
that you risk damaging the screw

Jack,
The KSB2 will always use its own filter (OP1, OP2 or OP3 - they are all
the same) to transmit. The important thing is that the K2 will use the
BFO settings associated with FL1 for transmitting. So if you do not
have the OP1 filter selected for SSB FL1, then the BFO frequencies will
