My Rosetta (with external antennae) used to work fine, but for the past 6 months or so it has become intermittent. It still occasionally shows the odd ADS-B contact, but it mostly shows nothing. It still broadcasts as all my flights show up on my base station, but I'm seeing more or less no traffic. I didn't change power leads or power supply before this problem started, but I have since tried new leads (all good quality, low AWG cables), a new Anker power supply of the recommended type, but no joy.
