Holger, If you do the DSP board exchange, you do not have to be concerned about the level of your current board - you will receive the latest level DSP board in the exchange.. I believe the LPF can be added to any DSP board level.
For other upgrades, consult the list at the Elecraft website to see either the serial number range or the cut-in date for each change - that should tell you which upgrade kits are needed for your K3. 73, Don W3FPR On 10/7/2011 12:49 PM, DL9HDA wrote: > Hi, but which Revision do I have? > > Revision C startet in may 2009.
