Paul,

I'll assume you're considering installing a DRA-45 with a? to give similar compatibility as a DRA-50.

The Yaesu FT-857D has a Mini-DIN-6 female data connector and requires a male to male Mini-DIN-6 cable to connect a DRA-50 (or adapted DRA-45) to this radio.? I offer two cable lengths:



The instructions on making VARA FM or HF work with a DRA are detailed on the website, here is the link:


Unlike VOX derived PTT sound cards - you are free to set the transmit level with any of the following controls:
1 - The onboard pots (usually R14).
2 - Windows Speaker Level - (doesn't need to be 100%).
3 - The "Drive" level in VARA.

The two DRA's mentioned here do not have VOX, and use "C-Media Hardware PTT" - which explained in detail here:


Other than setting the receive audio level (using control R12 on the DRA) the default jumper settings (for digital) should work fine.? Remember to properly select the RX baud correctly depending on the radio's mode.? If you're looking for a recommendation - the DRA-50M is a good choice, but a standard DRA-50 or even the adapted DRA-45 all have about the same performance and capability.

Hope this helps...
