*Single radio* microHAM interfaces do *nothing* with headphone audio. The microHAM MK2R+ (SO2R controller) can be programmed to switch any combination of Radio 1 Left, Radio 1 Right, Radio 2 Left, Radio 2 Right, *unused* sound card Left, *unused* sound card right to the user's left and/or right earphones. The programming uses microHAM's proprietary command language available to legitimate developers under NDA. 73, ... Joe, W4TV On 2015-08-03 5:29 PM, Guy Olinger K2AV wrote:
The counter to yet another mechanical outside box is that the ability to write firmware and update it inserts another very major possibility, that it can be done in the digital stream without need of extra cords and boxes. To use the mechanical box, we must physically route the audio to the box and plug in the headphones there. We have to mount the box so it doesn't move around. And worst of all, I have to make it. My microHam box doesn't treat a/b audio in this manner. "B" audio is radio 2 with its own stereo audio output. and it labels a pair of stereo lines RX1 and RX2. That deals with a pair of radios, not left/right stereo audio switching. So if I actually have two radios hooked up to it, no way to use it "creatively" to do the tricks just with the K3 in diversity. If I take my K3 anywhere else, like NY4A for multi contesting, I lose the function as what I get at NY4A is main antenna, RX antenna and power from the station, rather than a double of my now unique home station. Putting it in the digital functions makes it instantly portable. So, understanding your suggestion completely, and with no malice whatsoever, I decline, and still lean to the future with something that can be put in a macro stream sent to it from MM+ or whatever. I CAN take my MM+ macros with embedded K3 program commands. Feeding the A stream to the b audio just seems to be too easy in firmware, it's already done for non-diversity. Use of the diversity hold is problematic because it assumes that the unwanted half of the headphone audio is in the subRX side. 73, Guy
