Hi all,
With FD upon us, I have been receiving requests for a low-RFI supply
like the 14 V Kx33, but in a 19 V version for laptops. For those of you
who have such laptops, what is the current demand, and what is the most
common plug which such a supply would need to have?
Cheers, 73 & good
Rod:
Correct. Hc05 is Bluetooth 2.0. The Hm10 is BLE.

Thanks, Don.
I believe I found it. Or them, rather. I found two marked "030" in a bag
labelled "E530065", "2.7pF". The K2 RF board inventory says C22 is this
very same part number E530065.
Would you please confirm that the 2.7pF parts labelled "030" are indeed C22
for the RF board?

Yes, the linearity of the two power meters is suspect. However, the
compression of interest is near the high end for that of both the
KPA1500 and the K3, so I wouldn't expect their nonlinearity there to
make much difference. Note that absolute accuracy isn't critical.

Thanks Brian. I worked with Gary at Elecraft support who was a
big help in shooting the problem. Your message was also an
important clue, and maybe knowing about my problem will help you
with yours.

Yes and most power meters are voltage sensing instruments which are
calibrated to a specific value or load. Thus is the load being used may
not be the identical value to which it was calibrated, hence another
error enters the equation.
To wit, I have 3 "allegedly" 50 ohm dummy loads. Only
Most, if not all analog measurement devices are spec'd at % of full
scale which can lead to high absolute variances if the levels being
measured are significantly below full scale. A Bird with a 100W slug
accurate to 10% of full scale [+/- 5W] would be within spec if it
indicated a real 10 W
John,
You are exactly right for bring that factor to attention. Typically
wattmeters use diodes in their detectors, and the response will vary by
frequency and by the power level.
I would trust only something that has been calibrated to NIST traceable
standards. The Telepost LP-100 is one
Hi Scott,
I wonder how the linearity of the two power meters was evaluated?
Some years ago I checked the K3 and KX3 power meter against two other
meters. They were just within 10%

I just repeated the linearity measurements, on both 40 and 15 meters. I
used the KPA1500 meter to measure output, and the K3 power setting for
input. Results on the two bands were similar, though 15 required much
more drive.
On 40, the maximum gain occurred at about 800 W out, 17.2 dB. At
I was transmitting wspr on 40 at 100 mW from a WSPRLite tx, and monitoring

I think you mean the KPA500 is coming on with the K3 but the KPA1500 is not.
You can run an RCA phono patch cable from the 12V out on the K3 to the REM jack
on the KPA1500 and it will turn on when the K3 does.

Hi Bill,
I too suffered from issues as you are now with my KX3. Into a dummy load I
was getting high SWR numbers. I have been so busy at work that I haven't
had the time to find the fault, but what does seem to work for me is not to
tighten the case bolts too tightly. Looser is better, but not
MacOS supports the Serial Port Profile of Bluetooth just fine; it’s only iOS
for the iPhone and iPad (and presumably tvOS for Apple TV though I haven’t
looked) that doesn’t support SPP.

Mark,
I do not have a photo, but it is either a disc ceramic capacitor marked
with "3.3", or it is a monolythic capacitor which may be marked either
'3.3' or '339'.

A Piglet is overkill for my needs - its needs power and is another box.
At the moment my fixed station is in the roof - loft, and connects to a
Raspberry Pi 3 running WSJT-X.
I can operate it all via VNC from downstairs in comfort. It also functions
much as a Piglet when using Ser2Net to
Have you considered the Piglet by pignoly.net ?
The Piglet provides CAT via WiFi.

Does anyone have a hi-res photo of what C22 (3.3pF) for the K2 (s/n 7809)
looks like? My inventory says I have it, but now I'm not so sure - or, I
cannot identify it again.
Thanks.

Hi John,
if I remember well the HC05 is not supporting BLE. You need the BT class 4.0
or higher for all Apple gears if I am right.
