tranceiver

Virtually brand new. Kept in a case as backup radio for local volunteer fire department. Radio, antenna, AA battery pack, and manual. Contact w6caw1@gmail.com

I recently acquired a Regency HR-28 transceiver at a ham fest; unfortunately the power cord did not accompany this purchase. Though this is a mobile unit I would like to use it in my home. Please advise on setting up this transceiver. p.s. forgive my ignorance as I am new to amateur radio
