Why Yaesu System Fusion?

[Token]

I have read a lot of scientific papers where PHD's refer to specific radio frequencies as "tones", "monotonal" etc. it seems to be a recent thing.

C4FM is four level FSK. There are no audio tones.
It's not like feeding audio tones into the mic jack of an FM tranmsitter.

In some circles it is common to refer to each FSK step as a tone, even outside AFSK applications. So a 4-FSK would have 4 tones. Indeed, any discrete frequency change or step can be referred to as a tone, it does not have to be at audio levels although that is the most common application.

T!

Taking A Chance: DMR/P25 Radio That Can Also Be FPP?

N9UPC,


I haven't played with all of the digital modes yet. What makes Yaesu System Fusion is the best choice?

N9UPC,

The fact that Yaesu is dumping their repeaters for $500 each. They were originally rated at 50 watts continuous, but with heavy repeater failure, they changed the spec to 20 watts continuous. Many clubs are replacing their aging Mstr 2, & MIcor repeaters with the Yaesu, but they are still running them in analog, or mixed mode where the repeater received either digital, or analog, but only transmits in analog. This way club members who choose to not buy a Yaesu digital radio can still use their 2AT on the repeater. The reason Yaesu is dumping the repeaters so cheaply, is to hope all the club members will buy Yaesu digital radios to use on these repeaters. It's not working out that way though.

After listening to one for several months I've noticed they begin to drift when they get warm. Also, the club that owns this one left the RG58 jumpers in place.

Never noticed ours drifting at all - there is a nightly net on the one in analog that goes at least 30-40 minutes every night in analog. On our AMS machine, we have a net on Thursday in YSF mode that can go an hour or more, and again no drift. Both are at the 20w levels.

I have to hand it to Yaesu (again) for their marketing - now there is a 2m only, bare-bones dual-mode mobile that has a street price of <$200. They have definitely learned from Icom's mistakes.

I have played with YSF for over a year and I think that they have done a pretty damn good job of taking the best parts, IMHO, of some of the features of the commercial digital modes and tweaked them for ham use. The only thing I wish they had done was in the transceiver firmware to allow the mode to be set on a per channel basis, rather than as a global radio setting. I know you can leave it in AMS mode, but still it would have been nice.

Huh? Are you serious? So, you cannot scan a mix of analog and Fusion channels? That is ridiculous!

 

[N9PBD]

Yes, you can scan a mix, with your radio in AMS (Automatic Mode Select), it will switch to the mode received. If you scan across a C4FM channel with activity, the radio will switch to C4FM and decode, and your next transmission will be in that mode. Once scanning resumes, and you come across an FM transmission, the radio will switch modes, etc.

Yes and no.

This is their solution. I agree, though, that it would be nice if you could program a channel to be only DN or VW or FM instead of the mode not being saved with the programming. The mode is set by the "side" of the radio - i.e. the top/A 'side' of the 400DR can be set to AMS, FM, DN, or VW, while the bottom/B 'side' is FM (analog) only. [This is also basically true for the FT1D, 2D, 100DR (I believe).]

When in AMS mode and receiving analog, the audio will drop every several seconds as the radio checks for a digital signal.

Well chalk one up for DStar since I scan digital and FM channels at the same time all the time.,

 

[N5TWB]

I recall the ICOM manual does not recommend mixed mode scanning but I have an ID-800 and they may have updated that in the ID-880. Or, maybe I read that in the ID-51 manual.

You can scan both in YSF. Just because someone posts slightly erroneous information doesn't automatically give D-Star the nod...

Fusion

I bought one of the FTM-3200 Fusion mobiles at Dayton. It was only $169 so what the heck, a cheap way of getting onto Fusion.

While there are four Fusion repeaters in the area, there are almost no users. Trying to scare up a Fusion conversation is difficult. The only Fusion activity I hear are a few weekly nets.

All the activity still remains on DStar and DMR. With the cheap Chinese DMR handhelds flooding the market, the activity on DMR has exploded.

Also while Fusion is supposed to have better audio, I cannot tell any difference between Fusion and DMR.

So while there may be a lot of Fusion repeaters, there seems to be little actual Fusion use.

The only real improvement is in the higher data rate voice mode, which the FTM-3200 apparently only supports in receive mode. DN is exactly the same data rate as DMR.

FYI... I have several Fusion radios and none of them do this. Another feature setting must be causing the drop-out.

Not trying to argue here, but if you have it in auto mode on your radio (bar above the mode) and you are receiving regular FM (analog) then, yes, it will check for digital traffic every several seconds and you will likely hear a brief (<1 sec.) drop of the analog traffic. That is how the radios are designed to operate.

This does not happen, however, when in FM-only (analog-only) or in DN-only or VW-only. It only happens when the bar is above the mode (i.e. auto mode).

I have several, too, and they all do it because they are designed to do it. I know it's not just me because another local user doesn't leave his radio in auto mode because when listening to FM traffic the drop out checking for digital annoyed him...

Many radio clubs took advantage of the $500 Fusion repeater deal, retiring that 30 year old Motorola, or GE repeater which will probably outlive the Fusion repeater. But to get the old timers in the club to personally buy a Fusion radio probably will not happen. So they run the Fusion repeater in analog, or mixed mode so everyone in the club can still use their analog radio on the Fusion repeater.

Some of the first adopters of the digital YSF radios here were some of our local club's oldest members. They really like the digital. But yes, the 3 local YSF repeaters are used in analog FM the most...they all run in AMS > AMS.

Same here... I've never noticed a drop in the audio on either my FT1D or FTM100.

No, no priorities or weather alert set.
