[Elecraft] K2 RF board, NPO capacitors

[David Lankshear]

Hi all, hope someone can offer some advice on this.

 

I'm building K2 #5551 and was concerned that most of the RF board capacitors
listed as NPO appeared to be ordinary blue resin-dipped ones.

 

I mailed Elecraft tech support a few days ago to enquire if the caps
supplied were NPO (zero temperature coefficient dielectric) or whether that
spec was still required.  Guess I must have done something wrong because I
got no reply, so can anyone who's "been there, done that" kindly advise,
please?

 

I need to order a missing 68pF NPO from Farnell and if necessary, could
re-order all the NPO caps, just to be sure.

 

Grateful thanks in advance for any assistance.
