Bought this radio on June 1st. It fried itself by August 1st and wouldn't transmit on any power setting. Running it with a Pyramid power supply and a Nagoya 200c antenna, SWR metered around 1:1.2 on all power settings. BTech says this radio can't take SWR over 1:1.5, which is pretty low. Both power supply and antenna recommended and approved by Btech. BTech sent another radio at no charge of any kind. I really love this radio and hope the replacement runs well. Chirp is easy to use with this rig, and the radio check reports I get say it is clean, clear and loud. Hitting repeaters 30+ miles away with ease. I will post updates as they happen. review by John Miklor ... https://www.miklor.com/COM/Review_GMRS-50X1.php
