Re: [Elecraft] Elecraft K2 serial number 7699
Allan, Contact k2supp...@elecraft.com about that problem - in the meantime, do not wear out the core of L30, just set it to about the halfway location. Instead compress or spread the red turns of T5 to see if you can obtain the proper R30 voltage. It is not likely that L30 is the fault, but rather Q19, but Dave at Elecraft support can tell you more details. 73, Don W3FPR On 9/25/2023 9:19 AM, Allan Forster wrote: Sorry, made a mistake and used the wrong frequency while attempting to set up the VXO.

[Elecraft] Elecraft K2 serial number 7699
Hi, I have got to the VCO alignment stage of aligning my K2. I have got 7.4 volts on R30, this does not change when turning the core in L30. The core moves but does not appear to move up or down so I suspect that the VCO inductor is damaged. Does anyone know where I can get a replacement?
