Vertex has discontinued VXA-210 Nav-Comm Aviation Transceivers. This includes the VXA-210 Lite, the battery operated model and the VXA 210/16 Aviator Pilot Nav-Comm.
This comes on the heels of the discontinuation of the VXA-700 Spirit Nav-Comm Transceiver which was a popular model not only for aviation pilots, but also amateur radio operators. The VXA-700 was replaced by the VXA-710 but has only receive capabilities.
The VXA-300 Pilot III Airband Nav Comm Transceiver is a popular model and is priced at $329.99 at Touch & Go Pilot Supply.
