hello, very interesting webinar, can you share the developed tables?

Silly question, when simplex and dual capacity direct mode, only 12.5 khz is needed? On the other hand, when using a single repeater, total of 25khz (2x12.5 khz) is used (when not using single freq. repeater mode)? Basically, 2 time slots in, 2 time slots out? For DMR, is it ok to use 2 adjacent 12.5khz channels, or should there be "guard" frequency in between? Let's say an organization goes to the regulator, is it better to request a licence for 2 disjointed 12.5khz channels than 1x 25khz?

All DMR channels are 12.5Khz channels. There are 2 time slots in the 12.5Khz channel. They are TDMA, so not like in FDMA 6.25Khz apart. 2 x DMR timeslots in a 12.5Khz channel. TETRA frequencies are issued as 25KHz channels as they utilise 4 time slots on a frequency. Dual Capacity Direct Mode is utilising 2 time slots in Simplex Mode. If you need more clarification please contact Grant Sleep on 1300 121 155. Thanks for your question.

@@AceCommunicationDistributors The question was what spacing is used if for example you have 2 or more DMR repeaters. Each repeater has an RX and a TX frequency, so 12.5Khz each, 25Khz in total per repeater? And then another repeater that adds 2 additional channels, is it acceptable to just put the frequencies next to each other?

@@vzivadinovic We would normally run a minimum of 300Khz between repeaters on a site if Multi-coupling was being utilised. You can run them right next to each other at 12.5Khz each, but you may get de-sensing on the system

@@AceCommunicationDistributors Thank you! Very informative!
