Since I was ordering a K3, I asked if they could be included with that

At that time, probably 60 or so days ago, I was told that the mic would

The fact that the voltage dropped below 10 volts DC causes me to wonder
about the either the adequacy of the wire size used (for the distance
involved) or the tightness of the connections to the battery. A 110 AH
GSM battery should not drop that much with even 2 100 watt radios

We also ran my K3 at 100 watts connected to a 100 AH battery and solar
panel for a portion of Field day - the wire was #12 AWG about 5 feet
long and the connections were tight. Just for kicks, we checked the
voltage during a 100 watt steady keydown and found it to be over 12.3
volts after a
AP1 turns CW APF on.

The problem here isn't the battery AH capacity, but the voltage
supply. It could be dropping below 10 vdc because both radios are on
the same supply, or because the power supply wires are too fine gauge,
or because the battery is defective.
The K3 is less robust to supply voltage than the other

The K3/10 will run down to 9.0 V or so -- much lower than almost any
other desktop transceiver. Of course available power output will drop
at such low voltages.
The K3/100 needs 11 V to make 100 W on most bands (and higher on some
bands), but it should not shut down completely until you hit

Let me make sure I understand this correctly. Your K3, which is spec'd
for a minimum operating voltage of 11 volts, is somehow not up to the
task because it doesn't work properly at voltages less than 10 volts.
I look at it differently. Your power source was clearly not up to the
task, and
I would not want to be running an IMD sensitive mode like PSK with 11 V.
We came close at our location a few times between generator runs - 11.3 V or
so and my outboard IMD meter still showed an acceptable signal - IMD -25db or
less.

If your supply voltage is too low for a given application, I suggest
dropping TX power. In the case of PSK31, which works well at very low
S/N ratios, I suspect 50 W would have worked just as well as 100 W for
99% of contacts.

K3 voltage specs are 11-15Vand the Eagle spec is 13.8V +- 15%
that's about 11.7V- 15.9V. even though the Eagle would not shut
down you were definitely running below spec voltage and probably
causing some IMD if not excessive heat.

Hi Dave,
It might be worthwhile to keep an eye on 6m if you are not already doing

TEP or TEP + Es path. During most of this month stations in South and
Central America have been heard here at good strength on 10m
You might want to get a battery booster. Here is one
http://stores.tgelectronics.org/Detail.bok?no=10.
I can recommend that one. Had one for a couple years and use it to boost to
14.5VDC from whatever voltage any time of day from a solar-charged battery. I
think my K3 likes that 14.5V!
Ive been trying to resist the urge to call them, every call is precious time
taken away from filling orders.

A battery booster doesn't do much good very long if you're drawing more
