This is the hotspot ( here to buy ) using Raspberry Pi Zero. Then you have to buy a DMR radio, ie TYT MD-380 . can QSO with RKL too since RKL support C4FM DMR can bridge to WiresX <-- need to learn more about this If you hear like QRM on RKL, that means 2 person QSO using DMR on hotspot I used to hear 9W2DOV(Melaka) and 9W2KJS (Penang) DMR + MMDVM hotspot WW QSO if you want to DIY, here is the one with Raspberry Pi ( link to Bang-good.com ) mmdvm hotspot + piZeroW + DMR/C4FM radio DMR org selalu kat UHF. byk hotspots on UHF, though boleh gak work on VHF, tapi kena ada modification and probably tukar antenna hotspot macam node/gateway. same as simplex gateway. kalau ko pernah work on echolink punye gateway, camtu lah. ni DMR pun kena register number, dulu2 x payah hantar AA, tapi lately, diaorg nak kena htr AA utk apply for the DMR number Full set rm335~ ship to door step~ so, kalau aku ada radio c4fm and can transmit to RKL, meaning aku boleh qso dgn pp
