For FM repeaters, you can use the built-in 100 memories to scan repeaters.  You can program the KX3 repeater offsets, PL tones with the Elecraft Memory Editor, free for download from the Elecraft web site, too.

If you're serious about operating 2 meters on any mode other than FM, be sure to get the XG50 signal source and run the Temperature Compensation Procedure, also found on our web site.

Q: What is the exact product that I need to order to get the right 2M option kit for my KX3?

A: You will be ordering the right kit of parts based on what you currently have installed in your KX3.  Here's what you need to order:

Order this product If you have this in your KX3
KX3-2M-AT The KXAT3 internal automatic antenna tuner.
KX3-2M-NOATU Do NOT have the KXAT3 internal automatic antenna tuner

 

Q: Does the KX3-2M board use the same antenna port that I use for the other bands?

A: No.  The KX3-2M option will have its own antenna port.  It is an SMA type connector found on many popular 2M handhelds so there are a lot of options for antennas you can use.  Elecraft also has a number of adapters for SMA connections.  See the Accessories section for details.
