Tom in D.C. wrote:Doesn't a Phase 2 P25 radio revert to Phase 1 when it hears a Phase 1 signal? If that's correct then a Phase 2 radio has to be capable of both types of P25. Be nice if it did analog as well, but we'll all have to just sit and wait for Yaesu to announce the details. I'm thinking of a price in the $500 range, probably a bit more.
AL7OC wrote:Hope that they are also going to sell P25 and MOTOTRBO capable repeaters. Can't use TDMA mode without a repeater anyway. The local M dealer wanted me to look at MOTOTRBO handhelds, but unless you buy or pay airtime on a community repeater, the handhelds only work in analog FM mode. We'll have to see how this pans out.

Good on you Yaesu for telling it like it is..
Finally, a vendor that doesn't spruik the usual <careful> about how P25 and other digital modes always provide greater range and voice clarity than analogue when advertising it's 'digital' products. If only the other big digital radio players would be as honest..
sparktastic wrote:Yes, D-Star is dead in the water. I feel for those clubs and individuals who invested so much money into the equivalent of Betamax.
I am still doubtful that (voice) digital radio will take off in a big way in AR until a single (open) standard is settled on and equipment prices are reduced considerably. The problem is that digital systems, standards and technology are changing every ten years or so. So, why would any club invest tens of thousands of dollars on a digital repeater network to service just a few select operators, when that technology is likely to be obsolete within ten years?..
sparktastic wrote:The only way it will work, is if there is one 'open source' digital voice standard that can drive down the cost of the end user equipment/terminals.
It makes sence, at least in the US, that P25 become that standard as there will be plenty of surplus P25 LMR equipment coming onto the market in coming years. One of the main hurdles at the moment, is the licensing costs of the vocoder software. We need an open source vocoder suite that is compatible with P25 and which can be installed into radios from all manufacturers, including the Wouxun's of the world. Sadly, it is unlikely that DVSI will permit that to happen.
Live in hope though..

They gotta have instant gratification, I guess. Started off with re-purposing old tube radios for ham use in the '70s, and still doing it today, albeit with new technology.

But what about all the repeater owners running Mstr 2 repeaters, or similar "M" equipment? I'm sure they don't want to shell out $2000 for a narrow band repeater. A simpler solution would be to go to 20 khz spacing on UHF like they do in LA. That would up the count by 20% in heavily congested areas without going to narrow band. GARY N4KVEmmckenna wrote:
And what's this about running out of frequencies? Switch to narrow channels for pete's sake! No reason that Ham's can't start doing this now. Most of the newer gear will do 12.5KHz. No need to go to digital to do that.
ASTROMODAT wrote:No need to go to 12.5 kHz channels to free up frequencies. A more efficient way would be to dump all of the paper tigers, which would free up about 90%+ of the repeater channel assignments. Even the very few repeaters that are active have maybe 2 transmissions/day. Cellular has sadly killed Ham 2m/440 repeater use.
