I have a Yaesu FT-891 that I intend to use when on the road in my 40-foot Class A motorhome. My antenna is a Buddipole. I also have a Powerwerx 30 amp power supply that I use with my home base station. I will eventually acquire batteries to use with my 891 so that my operation can be more portable. For now, however, I'd like to use my Powerwerx 30 amp power supply to power my 891 when using the RV. The Powerwerx would be plugged into an exterior outlet on the RV, and my 891 would be set up on a table outside. We will have 50 amp service at the campsite. Is this doable? Are there other considerations of which I should be aware? I have no desire to hard-wire anything to the RV batteries. I am a new operator and am still learning. Thank you for your time.
