Thread: DSTAR & DMR Question

  1. #1

    Default DSTAR & DMR Question

    I plan to equip myself in digital next year in DMR and probably in DSTAR too.
    However given the much higher cost of a DSTAR equipment,
    I am afraid that this investment is not wise in the case where this mode is a day abandoned, moreover a person told me that Dstar was exceeded .
    it is certain that DMR will develop because of lower prices terminals I think.
    Apart from any polemics and Troll what do you think of the future of DSTAR vs DMR?
    Can I equip myself in both modes without fear or is it wiser to do it only in DMR and do with it?
    thank you for your constructive comments.
    thank you in advance

    Frankly, not much.

    I continue to use Echolink and am not venturing into Allstar. Both are analog over IP. Allstar allows one to have Echolink AND Allstar on the same node.

    I currently am on D-Star because a number of the folks out here are on that mode. A number of my friends in the rest of the world are on DMR.

    Give a listen to KT4ROY for DMR, Dstar, Echolink and IRLP all in one place.

    There is a place for all data methods D-Star has a good Repeater network but cost does exclude some hams from going that way.
    However there are now quite a few gateways appearing that support all 4 methods and interlinking works well
    So D-star DMR Fusion and P25 can all be linked together. This puts hams in a unique position that the commercial companies dont have.
    DMR is the cheapest option radio wise. and it has introduced a lot of Fence sitters into the world of digital radio.
    Im not sure where you are located tony, but if you are in the USA you have a very large network of digital repeaters that is growing quickly.
    Over here in the UK DMR repeaters are growing, however there are quite a few 4 mode repeaters being built.
    So who knows what the future mode will be its growing very quickly though!

    Can I first apologise it may be that I'm thick or just an age thing but can some one start at square one a tell me what digital radio is about, please?
    My understanding based on no prior information because everyone talks about DR (digital radio) with DMR Echo link PMSR? dunno I dunno. So start from the start what is digital radio?
    Is it one starts with a conventional radio and speaks into the mic the radio takes the RF and thru something with a lump of software imbedded in the 'something' translates the analogue signal into data this data is then transmitted and received some where that converts it back to analogue and bish bash posh my original voice transmitted signal is received at my called station?
    Sorry about the thick approach.
    Or have that all wrong??

    Yes, that's pretty much it.

    Voice is encoded to (pick one: dstar, dmr, fusion, p25) sent to a repeater and back to a compatible receiver.

    Many repeaters are gateways to the internet. In this case the signal travels through the internet to another repeater. The repeater could be 100 miles away or 10,000 miles away.

    Digital radio generally is static and noise free. If the signal is encoded or decoded with errors the receiver might hear r2d2 noises or nothing at all. Without (too many) errors sound quality is great.

    There is a lot I could add, but I'm just learning myself.
