Welcome to Tropical band

To most people the phrase "tropical bands" bring a pretty clear picture to mind - a bunch of shirtless guys playing calypso music. But to experienced shortwave DXers those two little words express the most challenging and enjoyable part of the radio hobby. The phrase kindles memories of a DXer's best catches and favorite QSLs, of exotic stations, music and of early morning listening sessions. (Don Moore)
I like the "Tropical band" name for new 60m allocation. (OK1RP)

Putting the K2 on 60m using K60XV module

Putting the K2 on 60m band using K60XV module

The K60XV adds 60-meter ham-band coverage to the K2 and K2/100 transceivers. In addition, it provides a low-level (0 dBm) split path interface for use with transverters such as the Elecraft XV Series.

60 Meters
Revision 2.04 K2 firmware allows the operator to quickly hop among the five fixed channels, as well as do channel-based scanning. The KPA100 option can be also used on 60 meters, but units shipped prior to March, 2004 will require modification (see page 2 of assembly manual).

Complete manual is here.


60-meter coverage Approx. 5.0 to 5.5 MHz; see text for permitted transmit frequencies
Transverter T/R control PIN diode switching
Transverter output Low-level, approx. 0.1-1.0 mW (-10 to 0 dBm); linearized RF/ALC detector
Current drain Typically 1 to 2 mA in receive mode, 2 to 15 mA transmit
PCB size 2.0 x 2.6" (5.1 x 6.6 cm)

Firmware Requirements
K2: Revision 2.04P or later main microcontroller firmware is required (U6, Control board), and revision 1.09 or later I/O Controller firmware (U1, RF board). Serial number 4060 and higher K2s already have these revisions. To check the revision, hold any switch while turning the K2 on. Two numbers will be displayed: your main microcontroller revision on the left (e.g. 2 . 0 3 D ), and the IOC revision (e.g. 1 . 0 7 ).
If either is not current, you must obtain an update from Elecraft (order #FWK2MCIO). This new firmware is included free of charge with the purchase of the K60XV kit on request.
