Just realized that my posted response addressed the other responses more than John's original query, so here is more direct input. The u2R is a superset of the DX Doubler feature set and more expensive. It is an individual decision as to whether those additional features are worth the higher price for one's needs/wants:
1. The u2R also has a manual mode, without computer connection, once it is configured with the Router on the computer. The manual features are less than the computer-connected features, but still everything available with the DX Doubler. 2. The u2R has both USB and LPT connectivity. The DX Doubler requires a complete LPT port, i.e., a USB-LPT adapter only supports printers, not the signal(s) needed by the DX Doubler. 3. The u2R receive audio switching is user-configurable to virtually any alternative. The DX Doubler has only 2-3 choices, but that may be all you want. 4. The u2R has transmit audio level controls for each radio, FSK keying for each radio, DVK, WinKey and a PS/2 jack for a numeric pad or keyboard. 5. The u2R has isolated USB, LPT and soundcard ports, although the latter are not needed with the K3's transformer-coupled LINE IN/OUT ports. 6. microHAM does not produce cables for the u2R, but I made mine up easily with parts from Mouser (DB9 connectors, DB9 hoods, and nice molded connector cables with phone or RCA Phono plugs on one end and tinned pigtails on the other end). 7. The u2R is expandable to MK2R capability by adding 2 microKEYERs in the future. In fact, most (all?) of the microHAM products can be integrated together all using a single installation of the Router software, with a tab for each box. The documentation shows the detailed interconnection of all the reasonable combinations of microHAM products. 8. Both TopTen and microHAM have excellent support that has been demonstrated for many years now. Ed - W0YK John, N0TA, wrote: > I want to try out S02R, and need some inputs on SO2R > controllers.

Device and K3 cables available at a reasonable cost. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
