The other problem with DX Doubler, if you operate CW, is that it does not contain an internal keyer. Thus, it doesn't know when you are sending by hand or by computer. If you're sending by hand, you need a monitor. But if you're sending by computer, you may want to listen to the non-transmit radio in both ears and not want to hear the monitor. If that's your operating style, then with DX Doubler you have to throw a switch to send with the paddle. This drove me nuts so I got rid of it. The Microham products do have internal keyers, as does my current favorite SO2R box, the YCCC box. They know when you're sending with the paddle and can let the monitor through without forcing you to listen to both radios when one is sending a computer message. The YCCC box is also the least expensive of the lot, does everything I want, and is, to my knowledge, the simplest box that includes an internal keyer. It's a club project, though, and not always available off the shelf. And it's a kit (a fun kit).
