OK, I've figured out the problem. I took a step back and realized I am
spoiled by the close integration of the K-Line. The reason the FT101 can't
key the amp is because, unless the K3S is turned on, the amp won't leave
STANDBY mode.
Even with the AUX cable disconnected, the amp sits in STANDBY a
Thanks for the great reviews on ehams for my KPA500 Digital Display Unit.
"The DDU is what the display on my KPA500 should be. It sits under a computer
monitor where it effectively displays the current telemetry of the amp. It is a
great accessory that keeps me from having to reach over and pres
The KPA1500 is new to me and very happy with my purchase . I'm using the
LP-100A watt meter and comparing it with the KPA-1500 they both read
close enough 10 to 160 . On 6m I'm seeing a bigger spread with the
LP-100A reading 1500w the KPA-1500 is showing 1375w . If you look at
this in DB , it'
I am reducing my asking price of the K2, SN: 7954 and hard rock 50 amp. I
will split them up if necessary. Neither have ATU's. K2 has the k2I/O and
KFIL, asking $650. The HR50 asking $200.
You pay shipping.
Contact me off the reflector, please.
Thanks.

This is not concerning to me at all . My curiosity and a cold rainy told
me to see how others compared . I suspect this is the case with any two
watt meters . I know it's adj
This bothered me a bit, so I took a good look at the source code and did some
testing. my results may be interesting.
Chuck’s description with the K3S Not connected to the KPA are correct. When
nothing is connected to the band lines, they are pulled high inside the KPA500.

Hello,
I have a guy trying to sell me a used KAT500, SN 0296. He sent me an actual
photo with the SN clearly showing. Also in the photo is KPA500 SN 0702.
Something seems suspicious. I did a Google image search, but the results
were inconclusive.
Does anyone in this group own, or has ever owned t

If my memory serves me correctly, power calibration is done band by
band. I suggest you calibrate the amp PWR ADJ to agree with your LP=100
for each band. Be sure to use a 50 dummy load and NOT an antenna.

I accept differences do to cable lengths and different points of monitoring.
No two will ever be the same when sampling rf at different points. Unless all
connections and cables are perfectly perfect "-)

I see something similar with my (non-Elecraft) amp. The amp's display
matches a Bird 43 I had connected with a 12 inch cable from the amp and
then goes into an accurate 50 Ohm dummy load. I usually do not leave
the Bird in-line, but had this set up for testing the amp when I first
got it.
