OK, the new K144XV-F costs 349.95. Also needed is KXV3A_UPGR (39.95). A total of 396.90. This is 26.95 more than XV144 and you don't have the inconvenience/pleasure of building it yourself.

I asked this very question at Dayton. The K144XV will cover 4Mhz of the 2m band while the XV144 only covers 2MHz. What I do not know is if K144XV allows 2m reception on the subreceiver.

This option board will have at least three features: (1) sub receiver AUX RF patch (to let the sub RX receive on 2 m even if the main RX is on a different band); (2) 144 MHz low-level I/O (for higher-band transverters); (3) a PLL to lock the K144XV's crystal oscillator to the K3's 49.38 MHz reference oscillator. This option will be available somewhat later than the K144XV itself, and the price has not yet been set.

Yes - It has its own mounting bracket to the side of the K3 and can be installed without or with the KRX3 sub rx. (You get a new K3 left side panel with the new mounting holes.)
