 I've been informed there is another modification out there being sold.  This modification simply jumpers the B+ to the 5v output of the regulator.  This means whenever the backlight is on the regulator is going to be fighting and possibly overheating.  The regulator is going to burn up eventually and/or the flex cables will overheat.  I've measured upwards of an 1200 ma of current draw when the backlight is on in these improperly modified radios.

 The key caps are likely a P27220 from Snaptron.

		+	== Notes on UCM parts ==
		+
		+	The UCM has no diagrams for it, and perhaps one of the most frustrating issues is having a working UCM, but broken connector. The connector is a Hirose FH12-45S-0.5SVA(54). This is Digi-Key Par Number [https://www.digikey.com/product-detail/en/hirose-electric-co-ltd/FH12-45S-0.5SVA(54)/H125151CT-ND/5723403 H125151CT-ND].

		+	The UCM is a well shielded multi-layer board and you will need a good size board preheater and hot air station to get the IC and resistors to come off the board. Go slow and it will come up. Don't worry much about melting the tape holding the snapkeys to the front, as it's a high temperature polyester material.

		+	There is a connector on the bottom of the board that looks about the same and will mate with the LCD connector. I suspect this is used to load the boot firmware on the UCM at the factory. It may be possible to restore a UCM via this connector in case of failed upgrades.

 It's my understanding any of the UCM's can do any algorithms, they just need to be programed via a KVL3000+ or later keyloader.

 The XTS series have a Universal Crypto Module (UCM) and Keyboard/option board combo.  Normally without hardware crypto, they will have the keyboard only option board, and the part numbers vary base on the model type (1.5,2,3).

 = Modification of Dim to Normal =
 There are a few UCM boards made for night vision equipment, and I reversed how to make these brighter by studying a couple good boards.  It's basically some current limiting resistors and a regulator.  In the dim UCM there is an addition of a 5v regulator which powers the LEDs rather than being powered via the B+ voltage of 7.5 volts.
