[Elecraft] little bit of information before I buy

[MC]

Sorry for any silly questions but I am  very new at HAM radio. I want to
take the radio in my backpack and which sometimes goes on my kayak,  I am
considering the KX1 as my first HAM radio, its small, light weight and has
internal batteries yet can be plugged into any cigarette  lighter when in
the camp sites. so I am looking into what future options can or do make the
whole project better.

From what I read on the KX1,  the total complete radio would be to order the
KX1,  with all three bands, the auto-matic keyer which makes a preset length
of code, so my dots and dashes will be all the same length,  that means if
you leave your finger on the keyer paddle  its will keep putting out dots.

But what do I do with the other three parts. ??? the balum, and the BNC
adapter, and do I have to have the MP-3 portable antennae , or will the
built in auto-turner work with any short length of wire.  And does it come
all the parts and with the enclosure, because it has on the list a custom
enclosure for $49.00.  And it mentions buying coils from some coil person???

but that is almost the price of the K1


thanks, its just a bit confusing.
