[Elecraft] Straight Key on my K2

[David Pratt]

Thanks for the info, Don.  My K2 is #01583, but fully upgraded with the 
Revision B mods.  R1 and R2 are 220 ohms.

I have a dual key. That is an iambic paddle and a straight key on one 
base.  My reason for wishing to be able to use the straight key with the 
"InP PdLn" & "AdEt On" menu settings is so that I can momentarily swap 
over to the hand key during an over to emphasise something.  Although I 
could change the menu to "InP Hand" it is obviously impractical to do 
this in that situation.

Not to worry.  If there isn't a solution to the problem by a simple 
component change, I am willing to accept the shortcomings of the K2 in 
this.  In all other respects the K2 is a marvellous piece of ingenious 
design and I have no hesitation in recommending it to anyone.
