I just installed the last of the capacitors into the RF board. I
happen to have a couple extra caps but I am also missing one cap. The missing cap is the 3.3 pF cap for C22 on the RF board. One of the extra caps is labeled "2.7C". I did a search of the PDF manual and cannot find a "2.7" cap anywhere in the K2 manual. The other extra cap is an 821. I should only have two 821's (C4 and C6). I have verified that C4 and C6 have the correct caps installed. Anyone have any ideas what this "2.7C" could be?

However, I think there is a serious typo in my manual along with the current PDF manual on Elecraft's site. My parts list, along with the PDF version, says the value of "C22" is "pF)". Something has obviously been cutoff. However, the "Description" for "C22" reads "NPO, "2R7", "3", "3.3", or "3R3". No reference to 2.7 at all. -- JT Croteau, N1ESE - Manchester, NH _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Ok, this has been resolved. Thanks for all replies. It has been
pointed out to me that "2R7" is 2.7. I still need to let Elecraft know about the typo in the Rev. G manual. -- JT Croteau, N1ESE - Manchester, NH _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The R is a place holder for the units boundary when there is no k or M to define the scale factor. -- David Woolley Emails are not formal business letters, whatever businesses may want.

Hello David,
In professional Morse I have often heard R used as a . (dot) in number notation. Hence 2R7 on a capacitor is most likely 2.7 pF. 73, Roelof Bakker, pa0rdt -- Mijn Postvak In wordt beschermd door SPAMfighter. 305 spam-mails zijn er tot op heden geblokkeerd.
