Has a modern yellow LCD screen (no CRT's here) and is super easy to use. Also has a builtin 70 watt rf dummy load with 3 different n ports for any combo of TX or rx or duplex. It is a bigger unit, but our radio team easily packs them up to our repeater sites. Weight is 37 lbs. These go on EBAY from $750 and up 2022 pricing.
