[Elecraft] [K2] KAT2 trouble shooting

Don: Built a KAT2 and all went well but no response at the first test. Question: can I separate the two halves and remove the L-C board and still power the KAT2 for trouble shooting? Should the processor board still respond? Any tips? Thanks Brian Denley KB1VBF Sent from my iPad

For interested k2 owners, after upgrading my K2 power supply to a 12 A Astron, I was looking for a better power lead arrangement than my homemade one using the supplied 2.1 mm circular lead. I found a 2.1 mm to Powerpole adaptor lead (3 ft) from powerwerx.com ($5.99) and I added a Powerpole

I am beginning to think I may have wacked or damaged the PIN diode for the T/R switch while adding the resistor for the KNB2. That might explain no receive or transmit that I am getting now. Does that make sense? Brian KB1VBF http://home.comcast.net/~b.denley/index.html
