<div dir="auto">I had a similar requirement for a work project. I used a RFM-69 module from Sparkfun and a CML CVSD codec operating at 16 kbps using FSK. I used a Raspberry Pi mini for control. It was overkill but made it easy to modify radio parameters on
the fly in my Python script. The RFM-69 can support up to 300 kbps and has allot of flexibilty in deviation. I operated it in continuous mode verse packet mode to stream my codec data. If you think this could help let me know.</div>

<div dir="ltr">We wanted to see if we could use the popular HT MD-380 for Opulent Voice. Turns out the answer is no. Here's a 2 minute video on how we figured it out.<br>

Do you know of a commercial bit of gear that can do roughly +/-15 kHz deviation? Or more. Most digital voice HTs are limited to +/- 3 kHz. <br>
