BFDX TD-503 DMR RADIO
I've been using the BFDX TD-503 for several months on the local DMR repeater and NCPRN. The main reason I really like it and its found its place above my Mototrbo and Hytera is it the GUI by default shows the Frequency and Channel Name. Controls are standard and easy to use. The case is high quality and it has some heft to it.
It has been left out in the rain, taken on swift-water calls (submerged in the river), dropped, banged, and otherwise abused with no issues whatsoever.
Programming is easy and the cable is inexpensive. The audio quality is better or on par with both my Hytera and Mototrbo's in both analog and digital mode. This radio works great on analog repeaters as well. I've been using this pretty much exclusively for any outdoor adventures (UTV'n, Rafting, Swift-water Rescue, Climbing) without fail, mainly because of its price point and performance. At $250 brand new its much less expensive than a used Mototurbo or Hytera.
I had some issues with the audio on this so bear with it. Also standard definition only.
Just a quick video of what's next in Ham radio and some projects I've been working on, as well as others, to get there. Some highlights:
- MultiCodec - Codec2, AMBE...
- Remote Standardized Head Unit / Retrofit
- Less PC .. More Embedded
- More modular
- Easier to use and the possibility of installing station away from Radio.
- DSP development in the hands of more people.
- Older Designs get updates.
- Powerful Tools getting more accessible
- KiCad (New stable, RF Traces (Curved), Diff Pair Routing (USB, etc))
- Inexpensive STM32 and other DSP platforms
- Filter Creation and Simulation
An open source codec for compression is up and going (CODEC2).
AMBE is much easier to implement and get ahold of.
Remote heads are beginning to pop up commercially in the FlexRadio line.
More embedded projects/products including SM1000, FlexRadio head unit, and many many DStar node adaptors.
DMR radios have hit the market to warm up the digital voice market, many which are under $300 new.
