Here is a look at the radio, and should answer some questions regarding this radio. Also a water test at the end.
It's a pity this radio will not work on repeaters. "One Time Slot" actually means that it transmits simultaneously on both time slots and it will be causing interference on the other time slot. Repeater admins on Facebook are now stating that they will ban users for using these radios on there repeaters.
Please keep these and other non-compliant radios OFF the systems. Keep it up and repeater owners will go to RAS and that means a lot of other perfectly good inexpensive DMR radios won't work anymore.
As a DMR user I find this to be useful information and that information is worth to highlight in other forums as well.
The video states that it's a Tier 1 radio, which explains the single timeslot "feature". Stick to Tier 2 radios. I'm not sure if Tier 3 radios are useful for ham use, but that's a different story since they are usually more expensive. Tier 1: specifies short range licence-free low power operation, mainly for personal or recreational use. Tier 2: specifies conventional operation in licensed bands. Tier 3: adds full digital trunking operation to Tier II capabilities, based upon the MPT1327 analogue trunking open standard, whereby radio channels that are available can be shared amongst users more efficiently. So that radio is specified as Tier 1 but probably breaks about every rule for that by the up to 8W power.
the problem is NOT tier-1 or tier-2 ..... this radio go to the DMR repeaters ..but transmit in BOTH the 2 slot... and this is not good !
