New General with a new HFradio has questions. Everything is unpacked. Nothing has been connected. Turned on the ASTRON p/s. Pretty good hum. Something to worry about? There are ring connectors to connect the radio wiring harness to the P/S. Crimp or solder? I don’t have a tuner, have a Chameleon EMCOOM II antenna. Radio is an ICOM 7610. Can I connect them together without worry? Any other concerns prior to powering everything up?
