RI is the only state that currently has had no QSO capable activity on 630m. I've secured the callsign W1R and will be setup at a nice open site in the Burlingame state park.  Intent to operate based on that location was submitted to the UTC (Utilities Technology Council) over 30 days ago with no reply, so good to go!The equipment will be a Multus Geminus SDR, a homebrew 300W class-D amplifier deck, and a 35ft toploaded vertical.  I've been testing the SDR and amplifier combo over the last three weeks, all solid. The antenna was just finished a couple of days ago for testing and I am still adding radials to get losses further reduced and should be able to get the full 5W EIRP w/ 300W TPO.Now I'm looking for portable power suggestions... need 12-14VDC for the SDR and 24-30VDC for the amplifier (12-14 amps on TX).  The portable power station options (Bluetti, etc) look interesting, but I've read of significant RFI (though some sources say only at 18MHz and above, yadda yadda)... so maybe it would be fine?  Unless someone has direct experience with one in particular, surely there's no way to know definitely unless I purchase and test one.  Deep cycle batteries?? Two in series? Only one with a DC-DC booster for the amp power?  Open to ideas and have three weeks to procure and test!  No generators are allowed between 8PM - 8AM and I will not use the car / battery... I've had issues with that in the past and don't feel like looking for a jump each morning!Thanks for any suggestions and hope propagation cooperates!73 Eric NO3M
