Overview
The Radtel RT-4D is aimed squarely at Technician-class operators stepping into DMR for the first time, or budget-conscious hams who want digital capability without committing to a Tier I brand price point. It sits in a crowded sub-$60 bracket, but the addition of GPS and Bluetooth gives it a feature profile that punches noticeably above that price.
The 3500mAh battery and 198g weight combine to make this one of the more carry-friendly dual-band DMR handhelds available, and portability is a genuine strength here. DMR Tier II support with dual time slot operation means it will work on most repeater networks, and AES-256 encryption support is a legitimate spec at any price. The 1024-channel memory is more than adequate for regional programming, and CHIRP-compatible workflows apply to the analog side.
Where the RT-4D earns caution is in its complete lack of water resistance and a feature set that scores only middling overall, suggesting some rough edges in implementation. At under fifty dollars it represents solid value for a ham who wants a DMR exploration tool or a lightweight backup HT; it is not the radio for anyone who works in wet conditions or needs a polished daily driver.

The RADTEL RT-4D is as described/specified. This radio is a nice size, and unlike many other radios, actually transmits at 5 watts. It has good battery life - at high power, I can work all my local DMR and FM repeaters. At low power, I can work my MMDVM hotspots for the entire day. Although you m...
These are amazing DMR radios for a great price, but do beware they are absolutely not beginner friendly. It takes a couple hours to program them if you want to use them like a walkie talkie, but other than that they're great. The big drawback is that, for whatever reason, the type C port will only c...
