First, thanks for setting up this forum!
Shortly we will be doing some work on the .685 machine to include setting it up in AMS mode to allow the use of Fusion digital as well as the existing analog FM mode. We have been using the Scopus .820 machine in AMS mode for quite some time now, and since the .685 machine is used more than the .820 machine, I think that some pointers for both the analog and Fusion users may be useful.
Analog (FM) Only users -
1) Unless you want to hear the digital noise whenever Fusion is on the repeater, you need to set your rig to use the 100.0 PL tone on both transmit and receive. Fusion does not require or use PL/DCS tones, so that will block the digital signal audio. If you have questions about how to do this with your radio(s), just ask and I am sure that someone can help you out with the programming. Note that you will not hear the voice announcements or the ID on the repeater as these are transmitted without the tone as well.
2) Once you program your rig(s) in this manner, you will need to check to see if the repeater is in use before you key up. All radios that I am aware of have some type of indicator to show that a channel is busy - either a LED or some other method of display. Some will have an "unmute" or "monitor" button that will open up the squelch to allow you to hear anything on that channel.
Fusion Users -
1) Leave your rig(s) in AMS mode so you can tell if there is an analog QSO going on.
2) Do #1 above so that if you are running Fusion, and the IDer comes on, it shouldn't pop you back into analog.
3) Leave your rig(s) in AMS mode!
4) Be considerate and remember that the repeater is used by analog users as well.
5) Be considerate and leave your rig(s) in AMS mode!!!
Yaesu has come out with the FTM-3200DR radio - it is a 2m, 65w mobile that does analog and Fusion. The street price is around $180, so it is a great radio to use in this area as all of the current and planned Fusion repeaters are on 2m. There are several in the club right now with Fusion radios, and a fair number across the river who check into the Fusion net on the .820 machine on Thursday nights at 8PM.
If you have any questions about Fusion (tech or operating), you can ask Dan, KD0IXM or myself and we will be glad to help you out!
