K1 KFL1-2 80m question C78/RFC8

[Tom Juelich]

Hello Guys,

I am just wondering what for are C78 and RFC8 on the RF board?
They are only supplied with the 80m kit.
I have a KFL1-4 and sometimes I am using KFL1-2  80/15m
which a friend gave to me.So I don´t have C78 and RFC8 installed
on my RF board.Could this cause any problems? What problems?
Can anyone tell me the value of C78 and RFC8?
Thanks very much for help!

I don't remember what Gary Surrency at Elecraft said about the problems that were found on 80m that required these components.  You could email him directly.

I just went ahead and installed them in my early K1 (which did NOT have pads for C78 or holes for RFC8) when I built a board with 80m.

C78 = 22 uF, RFC8 = 100 uH

I think it would be best for Elecraft to supply these two components standard with the basic kit so that all K1s would have them.
