Hi to all,
The Motorola MOTOTRBO repeater is yes a TDMA product. Keep in mind it is the first release offering and there will be many changes with firmware regarding these products. How about a TDMA product that will have the ability to have two time slots using the same frequency and what it you were able to have Digital Trunking. So do the math, on a standard Analog frequency you can have one conversation at a time. With the Digital TDMA, you get two voice conversations. Coming from SMR point of view that makes since. Now you build out a 3-channel LTR system, you have the three channels you license and pay around $1000 for the three and then about $3 to $4000 per channel depending on filtering and antennas and that are a bit on the cheep end. With the MOTOTRBO, you get two for one. I think you should get it by now. Take the Ham out of the equation here. What the manufactures are looking at what is best migration path to get to a digital format. Keep your eyes out on the product update for the new features for this product line here in the real near future. Kenwood & ICOM collaborated on the FDMA 6.25Khz path and works very well. However costs twice as much as a system operator to implement. We all HAMS will be at a digital standard at one time and we all know change is a hard thing to handle.

Try using one of those products for an Amateur repeater and I'll give you $1.00. Just about as useful. The product is stretching the limits of being a supportable product. It fits the other profiles of new radios where in this case without a Service monitor that does TDMA, you cannot align to 6.25 Khz and see or hear that the unit is to spec's. Just another name for D-STAR except this is being launched commercially first.
