Re: [Elecraft] KPA1500 v. 2.10
Yes, we agree - the delay and averaging for forward power for just the LCD display was incorrectly set to too low of a value in 2.10. Fortunately this is only a LCD display issue and does not impact the Power/SWR bargraph or internal operations of the amp. We'll get this fixed in a new f/w update this week.

Re: [Elecraft] KPA1500 v. 2.10
My observations are similar. With 2.10, the LED peaks now consistently match the numerical readings on my LP-700 digital power meter, The blue LCD power readings no longer reflect PEAK power on sideband. Rather they go up & down in a blur and thus are unreadable. In key down tune operations, the LCD power numbers accurately match the LP-700. 73 Torrey N9PY (#52) -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Roy Morris, Jr. via Elecraft Sent: Saturday, March 30, 2019 10/22:57 PM To: Elecraft Reflector Subject: [Elecraft] KPA1500 v. 2.10 After loading v.2.10 the LEDs seem to show the correct power level at or near the 1500 watt level.

[Elecraft] KPA1500 v. 2.10
I am seeing the same thing with the DIGITAL power metering. My LED bar graphs are working perfectly. It seems like the digital metering is not triggering correctly or not delaying correctly. The digital metering is acting very erratically on SSB and CW. It works perfectly on a Tune Carrier. I think this could be easily fixed in a Firm Ware update. 73's Ron Durie WB4OOA Elecraft K-Line 704-843-3681 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KPA1500 v. 2.10 addendom 2
Seems that the ammeter current is also much more erratic reading now while sending CW.

I have only worked CW mode so far, and the power reading is erratic and varies with 'duty cycle' -- a string of dots causes a very low reading, while a string of dashes is more accurate and less erratic.
