Hi
Actually 33 watts is more than enough to power a QRP K2. You only transmit
about 25 % of the time and receive the rest so running a K2 at 10 watts will
only require about 15 watts to keep the battery charged. For a 100 watt K2 you
will need about 75 watts of panels and about a 35 amp hour
Hi
I am kitting another batch of my Solar Controller Kits. There are two versions,
a high power and a low power. The low power is good for about 40 watts or about
2.5-3 amps and sells for $20. The high power version can handle up to 200 watts
or about 15 amps and sells for $30. The kits
Hi
The K3 has a PowerPole connector on the back of the radio and includes a kit to
build up a 5 ft cable to plug into the radio. The power supply end is not
supplied so you will need to connect the bare wires to your power supply or
supply your own connector for your power supply. The cable
Hi
Same here. I also ran out of range with a setting of 30. I usually use a OHR
WM2 and the OHR 100 watt dummy load modified with a 20 db pad output. However
the K3 seems to work fine and the internal wattmeter is accurate at 100 watts

I also found the black 4-40 1/4 screws to be short. I had 8-10 of the 3/16
black pan heads, 5 or 6 of the black flatheads and 5 or 6 silver 4-40 1/4 left
over. I also had plenty of lockwashers. I just used three of the silver 4-40

Hi
This is usually caused by the 8 volt regulator output on the low side of its
tolerance. Check the 8 volt supply if it is low say around 7.5 volts ask
support to send you a replacement. In the mean time just go ahead with the
build the agc and S meter are finalized later in the alignment.
Hi
I have the #3 and #4 plates with the Optiloupe swing down on the left eye I use

Hi
I don't have my K3 yet but I have had a problem like this with digital camera
firmware update. The problem was the Vista firewall. I had to turn off the
firewall to get it to work. Anyway it may be worth a try

Hi All
I ran the engineering department at a semiconductor burn lab for some years and
we had well over a thousand power supplies of analog, switchers and SCR
pre-regulated designs. We even modified Hobart MIG welders into power supplies
(0-60 volts up to 600 amps). It has been my experience
Hi
This voltage will depend on the tolerance of the 8 volt regulator. If the 8
volt supply is on the low side of the tolerance then you will not be able to
reach the 3.8 volts. However 3.75 should be close enough as this is just a
ballpark adjustment. The final adjustment will be made later by
Hi
I am an OEM supplier of controllers used in the waste water business. I have

They will usually spec a replacement but it is usually not pin
Hi
I have a method that works well for me to adjust the power/SWR bridge.
You will need to make up two additional dummy loads besides your 50 ohm.
These need to be 25 ohms and 100 ohms. I used 2 50 ohm 2 watt MOS resistors
mounted inside a PL239 connector wired in series for the 100 ohm and in

Hi
You must set the power control to about 1/2 scale and hold the tune button
to get into tune mode then as you tune L1 and L2 as the power comes up
readjust the power pot up or down a little to make the MPU re-measure the
power. You should reach a point where L1 and L2 will peak. If this does

To help any more we need some measurements in the transmitter. Did you build

The resistor and diode in the KBT2 limit the charge current to the internal
