Re: [Elecraft] 4S lipo battery for KX3?
I use a 4S2P 5200mah LiPo battery with my KX3. It lets me run 10 watts for a long time. I use the simple reducer in the “Articles” section of my website (www.ad5x.com) and just remove it when convenient when the KX3-monitored receive battery voltage drops below 14V. You can expand on this by enclosing the reducer in a small box with a switch across the diodes so you can short the diodes without interrupting power to the radio when the reducer isn’t needed.

Re: [Elecraft] [P3 SVGA] Has anyone seen garbage in the waterfall display?
Hello Hisashi, From the picture you sent, I believe you also need to adjust the SVGA bias way back. The adjustment is accessed from the SVGA menu. I had the same waterfall screen appearance until I dropped the bias back to around 2. 73, Bill - W0BBI __ 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
Re: [Elecraft] 4S lipo battery for KX3?
I use an ANKER Astro3 10AH battery charger from Amazon.com and elsewhere. Be sure you look at the one with a switchable 9volt-12volt output. It's designed to recharge phones and pads, but puts out 12.2 volts nicely. Comes with a plethora of adapters. Monty K2DLJ I use a 4S2P 5200mah LiPo battery with my KX3.

[Elecraft] 222 transverter repair

[Elecraft] What have I done? - RTTY
Can anyone think of a setting I would have misconfigured such that my K3 won't key my amp in RTTY mode? Worked all along and keys it fine on SSB and CW. Tried it this AM and only getting the rig output power (about 50-60 watts) and the amp doesn't go into transmit (ACOM-1000.) In fact, I can work guys fine with 50-60 watts, but still would like the option of using the amp! I'm thinking I must have some menu or even front panel setting enabled or disabled. This combo has worked for months . . . it's not band dependent . . . consistent across bands. Something seems to be not triggering the amp keying line. 73, Paul VE1DX __ 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
Re: [Elecraft] What have I done? - RTTY
How are you keying the amp? Key Out is a hardware output driven from the +7R line - see the schematics on-line - there is nothing in that output that is mode dependent. 73, ...

Re: [Elecraft] 4S lipo battery for KX3?
I use LiFePo4 batteries. 4s will go from 14 to 12V from 0 to 90% discharge. Perfect match for KX3 with full power all the way. No voltage reduction or noisy DC-DC converter needed. Search the Elecraft lists archives for mine and other posts with sources.

Re: [Elecraft] 4S lipo battery for KX3?
This is the first time I've read about LiFePo4 batteries; is it correct to say that one needs to pair a 3.2V AA LiFePo4 with a dummy AA? Does the timed charger module in a KX3 play nicely with this type of battery?

Re: [Elecraft] 4S lipo battery for KX3?
The LiFePO4 batteries have to be external. They don't fit inside and are completely different voltages and charge characteristics. They should have a balancing charger, many external universal RC chargers do that. I've posted links in the past to some chargers.

[Elecraft] Filter Problem
I did a master reset (by mistake) and think I have everything back to normal (didn't have a config back up) except that when I use the 500 and 250 filters I lose the signal, but hear an attenuated noise. I added a couple of dB gain to the filters but that doesn't help. Any ideas?
