Yes this will work but I would never use anything that small battery wise. I do have batteries also and they are hooked to a Low Loss PWRgate sold by http://ki0bk.no-ip.com/~PWRgate/LLPG for $50 it keeps the batteries charged for your power supply and with a power loss or power surge switches it the batteries so fast you never know when it happens. I have 5 radios and Astron PS it keeps my 4 190 AH gel cell batteries topped off all the time unless I have to run on them for over a week or better. When finished after a long outage I do charge them with a regular charger to a full charge it would take too long to bring them back up with the PWRgate.
I have found the vast majority of the automatic chargers create hash and unwanted noise in the radios. I notice it the most on my K2 and my FTDX-5000 on the high bands where it has better receive than my K3 on those bands. 73, Fred/N0AZZ -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Wiley Sent: Thursday, October 11, 2012 6:43 AM To: Bill Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 - what power supply are you using? Yes. You should also consider a 35 to 55 AH (or thereabouts) Gel-Cell battery and a 3 to 4 amp automatic charger. Advantages: (1) Instant emergency power good for several hours, (2) protection against line spikes (surges) and dips (brown-outs), (3) the small charger will make up the "daytime" discharge overnight without needing a much larger main power supply, (5) generally, while system ends to be rather less expensive overall, and (6) the battery acts like a huge ultra-capacitor that absorbs "junk" on the circuit powering the radio which helps with hum issues and such I ran my entire station from such a system for years. The station consisted of a 100-watt HF rig, a 50-watt 2-meter set, 35 watt UHF set, a Heath WWV receiver/station clock, audio processor, and several accessories, all from a 10-ampere automatic charger and a single Costco deep-cycle Marine battery. Any time I wanted to add something, I just hung it across the battery (I actually used a home-built a DC distribution panel) without worrying about needing to add yet another 12-volt power supply of some type. Also, didn't have to buy them - a savings that adds up to quite a bit after several rigs are added to the station. - Jim, KL7CC On 10/11/2012 3:09 AM, Bill wrote: > <snip> > Should I consider anything other than Astron? > > Thanks, > > Bill W2BLC > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
