Not after you've disconnected the charger. And the voltage drops VERY
quickly as they discharge. With 90% charge remaining, they're close to 12V!

Right on! For about a year, I've been running the radios in my shack
from a 10Ah LiFePO4 battery from Bioenne Power. I never see the voltage
drop below 13V on the K3 voltmeter.

Bob,
For a long time, rigs were designed for the nominal voltage obtained
from a fully charged Lead Acid battery which is 13.6 to 13.8 volts when
fully charged. Think automotive batteries and mobile operation - that
has been the design point for transceivers in the 100 watt and under class.
I am running a K3 with an RS232 connection to my Win 10 computer. Basic
early model K3. I also have a p3. I want to move from a Signalink
interface to a West Mountain Advantage interface to get some more
flexibilty. I use N1MM to contest on CW and Rtty...MMTTY. I also want to

Larsen makes a VHF mobile antenna that mounts on a vehicle window and is
fed via a capacity coupling arrangement mounted on the inside of the glass.
Some of you have been talking about an antenna that's known as a DDRR and
perhaps not realizing it.

Look at LiFePO batteries. The charging needs are specific (meaning
you'll have to make an investment), but they'll maintain voltage (13v+)
until they can't, a very sharp knee.

I agree, LiFePO4 4S batteries should be charged to around 13.2, with 12.6 volts
being nominal. LiPo 4S batteries have a nominal voltage of 14.8, but are fully
charged at 16.8—too high for most transceivers. I have seen examples of people
using various methods to decrease the voltage under 16.

Phil, the copper tape works on VHF/UHF with HT power levels, so at HF should
work well. Could even do multiple loops! Dimensions, will be the trick. We
need a designer to build and install and market for HF car top carriers! I am
not up to it.

Why are we stuck with 12 volt batteries of all types when the rigs are
optimal at 13.6 or 14 volts? Anyone know of a 14 volt battery mfg? My

Hi...
At the risk of jumping in on a forbidden subject I am actually waiting on
what a K4 might bring to the table. I'm currently the owner of a KX3.
Anyone that owns one probably expects a whole lot from Elecraft. In my
opinion, the KX3 is the machine of the decade. I also own a higher end SDR
and your point is??? or are you just attention seeking?

To me it is one of the charms of this list, that we get to read what is

me, as all my Elecraft stuff is auto filtered into a folder on my phone,
