[Elecraft] KX3 Battery Life

A quickie: wanna take it on a hike. Got my wire. Got the ATU. Charging up the batteries. Operating SSB QRP @ 5 watts (maybe less), how long would you expect the batteries to last? Operating CW same? David A., KC0XT David Ahrendts davidahren...@me.com

I’ve recently become interested in portable operating with my KX3. I’m using the Panasonic Enloop NiMH batteries. I find that the batteries last for less than 2 hrs. Should I expect longer battery life. I just charged them on the external Panasonic charge and confirmed post charge voltage >1.3

If you use SSB, and power consumption is a concern, you’re better off running at 3W, since a more efficient output transformer winding is selected, reducing transmit current consumption.  For CW, you can run up to 5W in this power-saving mode. You can tell if the hi-Z winding is selected looking

I don't have a KX3, but using my K2/10 @ 5W on CW, I've managed steady operating for at least 2 hrs with an A123 4S1P LiFePO4 rated at 3.5 Ah and I've never depleted the battery. I believe the KX3 is a bit more efficient than the K2. I also believe if you restrict the power to 2.5W, the KX3 uses

Matt, Excellent hint. You'll find you will NOT need one of the after market or Elecraft heatsinks either unless already operating in 40'C. 72 Dom M1KTA On 02/03/15 19:53, Matt Maguire wrote: If you use SSB, and power consumption is a concern, you’re better off running at 3W, since a more

Tom, It sounds like you may not have set the menu BAT MIN to 8.5 volts as recommended for NiMH batteries. The default before BAT LOW is displayed is 10 volts. 8 NiMH batteries will discharge quickly to below that 10 volt level, but the time between 10 volts and 8.5 volts will be much greate

I like to hike in areas where 2m is mostly useless. The weight I can carry is extremely limited, and the KX1 is about right. Hiking is slow and it takes time to get anywhere. Cooking and other tasks take time. I seldom have more than one hour to operate after everything else is done, including stat
