Don, All it takes is a 0.01uf capacitor, a 1N34 diode, and a 4.7 megohm resistor plus some wire and plugs to fit your DMM. There is a circuit diagram in the troubleshooting section of the K2 manual, just download the manual from the Elecraft site and search for 'RF Probe Assembly'.
If you want to see a neat implementation of an RF Probe, take a look at N5ESE's Ballpoint RF Probe http://www.io.com/~n5fc/rfprobe2.htm - it is a tight fit, but I have built a couple of these from time to time. 73, Don W3FPR > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Don Scippa > Sent: Wednesday, February 09, 2005 1:03 PM > To: [email protected] > Subject: [Elecraft] RF probe > > > Hi Guys, > Just ran into a problem with the K-1 vfo checkout.
