C4FM doesn't have "modulation tones" whatever that is.Fusion is C4FM but uses 4 different modulation tones than P25.

The questions that everyone has been asking for a year. It's curious to me why Yaesu didn't select compatibility with DMR or P25, particularly since Fusion is very similar to P25. But maybe it had to do with Motorola at the time owning Vertex Standard. Who knows. But Fusion seems to be gaining some foothold, there's just under 1,000 of them worldwide already. Compared to about 2000 D-STAR, 1100 DMR and 200 P25Yaesu Fusion marketing information is very confusing. It is bizarre that they are marketing a totally incompatible format. Why not DMR? Or at very least a P25 platform? Or better yet, software designed radios and repeaters that can be flashed with one of the other.

They spun the amateur/marine/aviation division back into Yaesu Jan of 2012 and at that point Vertex went from a 80/20 jointly owned company to a wholly owned subsidiary of Motorola that they now call Vertex-Standard LMR.Motorola let go of vertex in 2012.

Same with the ones around here. The clubs buy them up, as $500 for a new repeater is a great deal. But because of the poor cooling, Yaesu states the 50 watt repeaters should be run at 20 watts to prevent overheating. The repeaters are run in "mixed mode" so the repeater can receive analog, or digital, but will transmit only analog. This way users with older analog radios will not be left out. So Yeasu gives these repeaters away, but doesn't sell enough digital radios to make up for the loss. Sort of like when I go to the tire store for my $20 oil change [where they lose $] & they try to sell me repair work that I don't need. I then bring my car to a friend [a GM mechanic for 25 years] & he tells me my car is perfect, & the tire shop is trying to sell me unnecessary repairs. A few guys I know did set up a fusion repeater, & use it 100% digital, but the clubs are using them in "mixed mode" because not everyone [actually not many] will buy digital radios. By the way, DMR is growing by leaps, & bounds here. 6 different DMR UHF repeaters to use.Kicker is how many are used for fusion? I know a few repeaters bought cheap and only get used in analog mode.

Getting Fusion capable repeaters installed is the first step to getting any base of users. It's a chicken-and-egg question. Same with the radios. Maybe there's a critical tipping point when the whole system starts to click.Same with the ones around here. The clubs buy them up, as $500 for a new repeater is a great deal.

DMR is hot right now and certainly /the/ digital mode to be a part of, but I'd not kick a FTM-400 out of my truck if one jumped in.By the way, DMR is growing by leaps, & bounds here. 6 different DMR UHF repeaters to use.

Does it do cross mode? IOW, digital in/out <-> analog out/in? That seems like the critical piece to grow acceptance and be inclusive.Most of them went up in AMS mode. When the repeater is in this mode, it will transmit in whatever mode it hears. In other words, if the repeater hears an analog signal, it will respond in analog and if it hears a digital signal, it will respond in digital.
In this description how would someone with an analog radio know there's a digital QSO going on? If they are observant they should see the S-meter jumping or maybe hear noise, but it's possible they'd have no idea and just key up, right? Obviously good etiquette would dictate that you check by asking and upon your analog TX the repeater would switch modes. But wouldn't they potentially stomp on an in-progress QSO?If I understand it correctly, the Fusion repeaters, when in AMS on both receive and transmit, will transmit whatever the last mode was that they heard.
If you and I are talking on a Fusion repeater in digital mode and a third party keys up in analog mode, the repeater will switch to analog. Assuming that your radio and my radio are also set for AMS, our radios will switch to analog. When the third person is done transmitting, we can switch our radio back to digital and resume our conversation in digital.
