I found an interesting behavior on my 880 that could be alternately good or bad, depending on how you use it.
I generally keep one external antenna at a time hooked up to the 880 (mostly the MLA-30, sometimes a dual-band antenna that gets used for other radios as well). Yesterday, I had both attached and had switched to SW to catch something or other, and when a transmission came in on the transceiver section, it played it through, then switched back to the SW receiver. I think, but I'm not 100% sure, that it's the dual-standby setting under the FM radio.
Depending on how you set it up, it could be very useful to keep an emergency ear out while monitoring HF.
