I've been told that, back in the vacuum tube days, the filament in-rush current during initial turn-on--just like with the old-fashioned filament light bulbs--because the cold temperature resistance was a bit lower than resistance once turned on. To spare filaments from degradation ops would leave their radios on all the time. (Although given the idle current of tubes when the radio's not in use to transmit it would, eventually after enough hours, would maybe exceed the cost of replacing the tubes if the filaments wear out quicker with constant turned on & off).Not sure this is the proper forum but here i go. Just wandering if you guys leave your radios on all the time or turn them off when not using them. I am mostly speaking about base station transceiver/receiver. I for one leave my radios on all the time but not really sure if i should or not. What do you guys do ? any recommendations ?
I agree there . Depends on your situation. Older scanners for instance that have a dimmer switch will keep the led bulbs lasting longer. Ham rados that use certain type of bulbs burn out if left on all the time (Alinco 1200) for instance. But my FT-990 runs 24/7.I had equipment at work that had been powered up continuously for 20+ years. Honestly, we were afraid to turn it off since we were never sure if it would turn back on again.
There's some logic to keeping it turned on all the time if the power supply is stable.
My main transceiver, Icom 746Pro, I turn off after using simply because I don't want to leave the power supply turned on. I do leave a few choice scanners on 24/7, my BCD536HP, SDS200, and my BCT15X.
I have one in the kitchen that's on 24x7. That's a good application for CTCSS squelch. I set our radios to TX with the tone and that opens the radio in the kitchen. All the other radios are carrier squelch on that frequency.Still, I'm not sure if I want to leave my 2 meter rig monitoring the local repeater just so I can wake up out of the bed to hear some jaw jacking. The price of radio vigilance I guess.
