According to the Standard Horizon GSX1000S manual, the radio can be set up to automatically switch channels upon receipt of a DSC call and sound an alarm, or it can be programmed to notify you that a call is received so you can then switch it manually to the talk channel. I’d choose the latter and then you are in control and can switch back.

How many folks use DSC to make ship to ship calls, and if so what does your radio do if you don't answer? Personally, I like having DSC, because sometimes when in a crowded area the radio chatter can bea bit much. And, also, my VHF receiver has been blown out by folks sitting next to me and transmitting with HF Radio at those incredibly powerful wattages, and now my VHF picks up anything within 1/8 mile that's within a few channels of where I am. So I end up leaving my radio turned way down, and anyone who wants to talk to me can use my MMSI to call because theDSC ring is loud. (It's also relatively private, so everyone can't follow alongfrom the hailing channel and find out all about who's on the boat and what I'm having for dinner. <VBG>) Sohere's the deal. On my radio, and every other person I've talked with, the radio remains on the channel that the caller selects before placing the call. (For those who don't do this, to use DSC you find a clear channel first and then dial the MMSI of the person you're calling.) When you place a call, the radio uses Ch 70 for the digital handshake, then switches to the clear conversation channel. That's cool, but if the person isn't there, or is too busy to deal with a radio call, the radio remains on the selected conversation channel. Example: I come back to the boat and the radio is on 72,and the display shows the last received call. I think that's a safety issue, and wonder if current DSC radios have a way to automatically go back to the original channel if a call is missed. Imagine not hearing a call while underway, and then the radio sits on 72 and you miss a May Day or a weatheralert. My radio is 12 years old, and everyone I know has a first generation DSC radio, so I wonder if the new radios address this.
