Okrem toho, že tieto TRX vedia len TS1, spôsobujú s aktuálne dodávaným FW rušenie pri vysielaní aj na TS2.

Takze rusenie TS2 je vlastnost, nie chyba a uprava FW nic nevyriesi. http://forums.radioreference.com/budget ... today.html
Listening to the output in FM analog mode, it sounds like the Baofeng MD-5R is broadcasting on both time slots, rather than only one. That's why the TYT MD-380 sounds choppy--you can hear the TX turning on and off every 33ms or so, while the Baofeng MD-5R TX is continuous.
Cinania si zjednodusili robotu a moduluju FM "digitalom" bez vypinania TX v case pre Timeslot2. A dalej pribudaju dalsie typy low cost DMR pod roznorodymi nazvami, zvycajne v cene 60-90€. MD-5R je tak dualband FM rucka doplnena o "DMR nadstavbou" v style MMDVM k FM radiu.

Mozno by stalo za namahu spisovat taketo cuda na samostatnu web stranku a priebezne doplnat. V Kosiciach sa uz taketo radio objavilo, takze treba potencialnych kupcov vopred varovat.

Na stranky OM0ODB som dal vystrahu, v pripade zistenia pouzivania takehoto radia hrozi blacklist na ID prevadzkovatela.

Natrafil som zatiaľ na:
2017 Baofeng DM-5R
Baofeng DM-5R plus
Chierda D100
Retevis RT81
TYT MD-680
TYT MD-398
Radioddity GD-55

Nie su to rovnake radia, lisia sa poctom "kanalov" , ovladanim, displejom... Chvalia sa kompatibilitou s TIER II, ze vedia len Timeslot 1 casto nebyva v ponuke uvedene a treba patrat.

V 2018 mají už i baofengy umět 2 timesloty. Otázkou je, kdo to za 70- 80 USD vyzkouší .

DM-1701 80usd
DM-860 2019 70usd
DM-5R 2018 65usd
