This is a special radio I've added to my collection. It's a combo FM/digital radio. The digital mode is dPMR446. Both FM and digital use fixed frequencies that lie within the US Ham 70cm band so it's usable there ONLY. The radio has no FCC ID or certification to be used anywhere else.

The radio requires KPG-202D to do the programming.
This radio is a replacement for the older TK-3401D, which apparently there are V1, V2 and V3 versions.

The radio is designed for license free use in the EU zone. The dPMR446 mode is very slightly different from the full featured dPMR mode used commercially in the EU. The two standards for reference are the document names below.
For dPMR446 : ETSI TS 102 490 V1.9.1 (2016-08)
For dPMR : ETSI TS 102 658 V2.6.1 (2019-01)
I should point out the TK-3701D is really an NX-1300 series radio loaded with the special dPMR446 firmware, instead of the usual DMR or NXDN one. Looking at the service manual for both I can't really see any differences electrically.
