Gentlefolk,
I could do with some advice. I am at Page 72 in the K2 MANUAL aligning
the TX for 40 Meters.
At 5 watts output the current drain is supposed to be 1.3-1.6 amps. The
book says if it is *much* higher than this, or the Voltage drops more
that 1 Volt I may have a problem with the TX, load or PSU.
The figures I get are: -
Tx Off...13.8 Volts 200ma
Tx on...13.1 Volts 2.16 amps 5 watts out according to the K2 internal
meter, 6.1 watts out according to Motorola R200D comms analyser....which
contains the dummy load...the PSU is a large Palstar 30 ampere gizmo
thus oodles of spare umph.
Setting the power at 10 watts I get the following.....
Tx on 13.0 volts, - High Current warning then 2.44 amps 10 watts out
according to the K2, 7.87 watts according to the R200D,
the manual says "if the current is *much* higher than 2 amps see
troubleshooting....."
The R200D tells me the output frequency is very stable...and after a
short warm up that the power out of the K2 is not fluctuating .and I am
assuming that its dummy load is good...the interconnecting lead looks
fine though it is rather (i.e. 10 meters) long.. And I am using a bnc to
ntype adaptor at the R200D end. The K2 current meter tells me that after
about 30 seconds the current is stable at the values I have quoted above...
So the 64,000$ (£37,647) question is......do I have a problem or
not...normally I would go through the trouble shooting stuff but the
shack is as cold as heck at the moment and I have some other things to
do......and M0PUB wants a sked when its finished and I have the ATU,
Sideband and 160 meter options to build and the battery option and I
want to get it all finished in time for the winter sports.....
Greatful for any advice,
Steve G0XAR
