BioennoPower LiFePO4 batteries solved my power supply birdies problem. I now run the KX3/PX3/KXPA100 and the K3/P3/VGA monitor each from a 40 Ah battery. They came with chargers so I habitually recharge whenever I QRT.
It's so nice to be free of AC mains restrictions and free from linear supply inefficiency as well as switching ps noise that I've purchased their Pelican model 1200 watt hour model to act as backup to the 40s and to handle my field day power. That big power pack has a builtin inverter and solar charge controller as well as USB outlets to recharge/power my portable speakers and the MacBook Air. It seemed expensive at first but then I took another look at the investment in Elecraft gear and decided power for them isn't THAT expensive. -- Marc W8SDG > On Dec 21, 2015, at 12:34 PM, Jim Brown <[hidden email]> wrote: > > Here's a nice discount on excellent LiFePO4 batteries.

Can one keep the battery on the charger and run the radio off the battery
simultaneously? I wonder how long I can run a K3s/100 off one of these batteries...

Charger voltage as it finishes the internal balance cycle rises to 14.6 volts. The K3 and KX3 seem happy then.
40 amp hours at 12-13 volts should last 4 hours key down. I don't usually last that long. But the charger QRN is about S2 so you could conduct tag chew QSOs while recharging. My approach is to have a backup ready. YMMV -- Marc.

Has anyone experiencing these RFI problems tried passing the power cable through a large mix 31 donut to see if the noise is eliminated? Worth a shot…

Oh, yeah. That's the first one I bought from them at the summer sale, and I did complain right away. Those are ideal for powering the KX3 and I carry one in the Pelican with my bare KX3. The USB port is used to power a plug-in LED lamp.
I do wish more people making those power supplies could read English. I'd send them a copy of Parts 15 and 17 to read. It's going to take a concerted effort for all 170,000 of us U.S. hams to convince these people. I even had to hand a cheap transistor radio to a rep from our electrical service company to he could listen to the LED power supply he planned to install. He was surprised. I was appalled. -- Marc SDG > On Dec 21, 2015, at 4:13 PM, Jim Sheldon <[hidden email]> wrote: > > It is their BLF-1203T 12 volt, 3 Ah battery. > > Jim > > Sent from my iPad > >> On Dec 21, 2015, at 3:00 PM, Marc Veeneman <[hidden email]> wrote: >> >> Which one?

My radio club, Newport County Radio Club (W1SYE), has been using a Bioenno
Power 30 AH LiFePO4 battery for a few years on many of our Island on the Air activations as well as Jamboree on the Air. We were running a 100 Watt HF radio from early morning to sunset at 100 watts output. In all our activations, we have not come even close to depleting that battery, less than 20 AH were put back into the battery on charge. Those IOTA events generate large pileups and hundreds of QSOs over a period of about 8 hours. I've also run a K3 on Field Day, at our GOTA station, for 16 hours out of the 24 hour period using a LiFePO4 battery. During that time hundreds of QSOs were made at 100 watts. At the time I was using a 60 AH battery, and the current consumed was 34 AH. It certainly helped that the K3 has low RX current as well. GOTA is not as demanding as a full blown CW run station, but it is certainly more than casual operation. Our full blown Field Day run station is run off a 9 AH LiFePO4 battery for a full hour to obtain the Alternative Power Bonus -- In that time, hundreds of QSOs are made, and the battery is more than up to the task. Expect that a hard core contester using a K3 in full run mode will consume about 8 Amps an hour (8AH). A search and pounce station will consume about 2 Amps per hour, and casual operation will consume about 1 Amp. All at full output. 73, Bob, WB4SON On Mon, Dec 21, 2015 at 4:20 PM, Marc Veeneman <[hidden email]> wrote: > Oh, yeah.

My electric co-op is trying to be cooperative (no pun intended). They even
hired these guys (highly recommended by ARRL) http://www.rfiservices.com/ to teach them a workshop and they plan to have another. Also on the site at http://www.rfiservices.com/fccwarning&citations.htm are some interesting examples of the way the pre-Obama FCC handled power companies.

I use three discarded 12v server back-up bateries which are discarded
from the server room after one year of service, but are generally worth three to four years usage. Mine are connected to a West Mountain Super PWRgate PG40S between my Power supply and the 12 volt equipment. When the mains power goe's down there isn't a flicker in my 12v equipment.

I’ve got a Bioenno Power BLF-1212WS (LiFEPo4) sitting here on my desk, being charged by their supplied 117v charger, model FY1502000 switching power supply. It makes zero hash or crud on my KX3, K3, or SoftRock Ensemble RXTX (40,30, 20 meter version). No ferrite donuts wound on my leads. What power supply are you using?

Unknown mix, but it's next to useless. I put a multi turn choke of 31 mix on the output of the charger. No luck. The radiation is mostly out of the case and coupled to the AC cord. Chokes there didn't do much either. I even made sure the outlet it was plugged into was on the opposite phase from the radio's DC supply. Ran the KX3 on internal batteries while the LiFePo battery was being charged and the RFI was still over S7.
