Been soldering. A bit lately. Here’s a DRA818V breakout and a 144ish MHz bandpass I put together, before I absolutely wrecked the coils to tune them. NanoVNA arrives this week so hopefully I can more accurately tune this and my trash antennas
The DRA818V’s serial interface is a bit obtuse. I followed directions for everything and I just cannot get aerial parameters correct for it. I measured the logic levels and I’m definitely handling TTL properly. Got so frustrated I took a full break from radio shit this week.
