[Elecraft] Laptop Power Supplies

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

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? Many

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. 73, Scott K9MA On

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. I ended up taking out the 2M board and the ATU board and the KX3 worked. I added in the ATU

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% http://www.kn5l.net/Elecraft/Power.html John KN5L On 06/19/2018 04:56 PM, K9MA wrote: > I just repeated the

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 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. 73 John N5CQ -Original Message- From: elecraft-boun...@mailman.qth.net
