I recently posted over on the Airspy Groups.io list asking about replacing the SMA connector on an Airspy R2, but didn't receive any certain feedback, so am trying here. The SDR had an "incident" in prior ownership with a badly mis-mated cable that destroyed the center contact and damaged the dielectric, so I'm never letting it touch one of my nice RF cables. Unfortunately, I don't have calipers to measure the connector out or a selection of similar connectors to just try out. What I'm looking for: the SMA connector part number (or equivalent) that is a drop-in replacement to maintain compatibility with the stock case. Any authoritative ideas?
