K2 - No RF Output

[Mark, KJ7BS]

My K2 has lost all TX RF output.  I replaced the driver, finals, and bias transistors and still have no RF output.  I no longer have access to a scope, but I have done voltage checks.

I've gone through the troubleshooting in the back of the manual, but that did not reveal anything.

Mark,

I suggest you use an RF Probe (there were parts for on in your K2 kit) and follow the steps on the Transmit Signal Tracing in the K2 manual Troubleshooting section.  Do the steps indicated in the order listed.

Let us know where the RF voltage drops off significantly (it will likely be higher than expected prior to the failing stage since your K2 has no output).  Once you have determined that point, we can investigate that stage in detail and hopefully resolve your problem.
