John, I haven't read all the replies yet. I'm sure you will get a variety of responses, such as mine. About 40 years ago when color TV's were more expensive, my neighborhood got a momentary hit in the power, and it came back with a voltage spike that took out too many TV's to count. To

Re: [Elecraft] Uninterruptible Power Supply for K3S (power line arc noise)

John, Power line arc noise can happen anywhere, even in a semi-rural area like your neighborhood (I used to live in Acton MA). There are many web resources for learning how to identify and track down power line arc sources. Here are some things I've learned by hard experience. A good, though

In response to Stengrevics : To deal with a power line noise problem, someone suggested I try an uninterruptible power supply (UPS).? Does anyone have any experience doing this?? If so, what UPS specifications are appropriate to handle the K3S? For my Elecraft K3S/P3 I am using an Astron RS35M

Re: [Elecraft] Uninterruptible Power Supply for K3S

Thanks to all for the comments. Not being familiar with these things, I thought the UPS could be use for a protracted period of time. Jim - I’ve been through the exercise of turning off every breaker in the house except the one that supplies power to the shack. I then unplugged everything in

The "UPS" for my K3 consists of an Astron RS35 linear powersupply driving a West Mountain Radio Super PWRgate PG40Sto a 105Ah AGM SLA battery. Power to the K3 comes from aWMR RigRunner 4012 that's plugged into the PG40S. Very quiet,and can be deployed fairly quickly. 73 de N1HO
