Ed ..... All our repeaters are digital ready. ICOM digital radios are being bought for our shop NOT because they work better but we are going to paging and messaging. which the F-4 and F-43 radios will not do. The DIGITAL ones DO NOT work as well but are good enough with our voting receivers. Our ANALOG repeater we have 4 of them run over 100 watts and the digital ones will run the same. That said the ANALOG system wil remain on the air..

And very few of them are digital vs analog. Quite often there are a number of things that are being done when an organization switches from analog to digital, different repeater sites, different antennas, different everything. And like everything else, government isn’t known for always doing things the best way. There have been a number of studies that show that D-STAR can have better coverage. The FEC in D-STAR can have wonderful effect on communications. But there also have been a few that show in some circumstances, the coverage can be less. That’s why I just tell people that it’s about the same.

I work for the SO and we are ANALOG because MOTOROLA digital p25 does not have as much range. all digital buys us is the ability to transmit data with voice. You are the first person who stated different. The fact it buys us nothing is why we are still analog both trunking and uhf. --- On Sat, 5/8/10, Doug Ferrell <kd4moj-lists@ embarqmail. com> wrote: From: Doug Ferrell <kd4moj-lists@ embarqmail. com> Subject: RE: [DSTAR_DIGITAL] Re: I Want To Know???

ANALOG has more range Analog has more range? Maybe your location but not here.... D-Star has proved it has more range, same site/antenna/ hardline as analog. When it replaced the analog repeater on the site, there was a definitely range improvement. Same antenna, same cable, and the digital D-star) repeater was 35 watts less in power. So maybe in your situation you were not doing an exact replacement. The 800mhz Motorola system in town was replaced by P25 digital recently and field test proved that digital had extended range over analog. Both analog and digital were operational at the same time from each of the 7 sites, and we had both radios analog and digital, and each time the test on analog was "broken up", the digital came through. There were several times where neither were operational from the test locations. There was never a test location that analog exceeded digital range. Before we went through the testing scenarios, I had the opinion that digital was going to be a problem, less range etc. But when the test were concluded a week later, I became a firm believer. It was simply amazing. Just my 2 cents! [GRIN] ...DOUG, KD4MOJ 30MDG#1076, FH#1125 KD4MOJ-63 APRS Messenger 2.48
