[Elecraft] KPA1500 Questions + RFE
"Is there a downside to using a very long FAN DWELL TIME, other than noise? I am trying to get my amp to run cooler." Your question seems to imply that you believe increased dwell will make the KPA1500 run cooler. I wonder if you have any test data that supports that assumption. My testing of my KPA500 showed no significant advantage to pre-cool or increased dwell but I don't claim to have explored all possible operating conditions. I suspect that the most effective way to reduce temperature will be to lower the fan speed temperature set points. There is a trade-off between temperature and noise. The recent increase in the KPA1500 fan setpoints seems to suggest that Elecraft has chosen to reduce noise. Yes, there is a downside to very long fan dwell time. The fans will run longer and therefore wear out quicker. Why do it unless you have data that shows some advantage? "FANticipator" may help: - https://tinyurl.com/y4tw92zz.

[Elecraft] KPA1500 Questions + RFE
Dear Brain Trust: 1) Is there a downside to using a very long FAN DWELL TIME, other than noise? I am trying to get my amp to run cooler. 2) Does anyone offer a KX3 to KPA1500 serial cable, and a K2 to KPA1500 serial cable for sale? No, I can no longer build them myself, even though they are simple. 3) Is there a way to command via macros the KPA1500 to run the fans at normal speed + 1 as the amp starts to heat? Can this choice be implemented in firmware? 73, Eric WD6DBM __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KPA1500 questions...
Mark,
The amplifier is not keyed while the KAT1500 is tuning.
Similar to the KPA500 and KAT500.
You do not have to put the amp in standby, it is done automatically.

Why would you need the HF AUTO ("My question is this. Is there an option

has a built-in tuner. Is there a reason you do not want to use it?

I read this is a remote tuner? Thus the question?

Subject: [Elecraft] KPA1500 questions...
Group good evening. I have a certain style of operation and a question about
the KPA1500 I would like to ask in the group. My normal operation is the K3S
into a Palstar HF Auto that tunes several antennas on my property.
I have had a lot of amplifiers in the past, from solid state to tube amps.
Currently I'm running a OMpower 2000+ amplifier. My normal process is that I
have 2 memories set on the K-pod, one is that it puts the radio into tune mode
at 8 watts out. This 8w output tunes the HF auto with low power until it gets a
good match which is very quick. During this 8w tune I have the amplifier in
stand-by mode, and all set to tune it next. After the 8w tune, I have the same
button set up to "HOLD" the button for a 30w tune in which then I tune the
amplifier which is pretty much ready to go off of a list that I compiled, just
basically a touch up is all that is needed. The radio stays at 30w after that
tune and I'm ready to go... My question is this. Is there an option with the
KPA1500 that I don't have to reach over and keep hitting stand-by on the
amplifier every time I need to touch up the HF-Auto, can I set up a K-pod
button to do this, or a button on the K3S? So basically does the K3S talk to
the buttons on the KPA1500 so that I could create a stand-by butto
n on the K-pod...I'm right on the fence on a purchase and this feature would
really be of importance to me...

Re: [Elecraft] KPA1500 questions...
Hi, Jay! The KPA1500 bypasses the power amplifier during ATU TUNE. Your K3S can communicate its current VFO frequency to the KPA1500 via the ACC cable. The KPA1500 will then change the ATU based on frequency, without transmission. If you have several antennas, as I do, I've done the tuning on each antenna about every 20 kHz across the band in what we've called an ATU "training session". The KPA1500 retains ATU settings for each of these antennas for each "band segment". Then when you QSY to that frequency and transmit, the ATU evaluates SWR, if it's above an SWR threshold (that you set), then the ATU switches the PA to bypass, runs through the available ATU settings, and picks the best one, then restores the PA to full power. Depending on how many antennas you've tuned for, this takes small tens of milliseconds, about 15 msec per ATU setting that needs to be evaluated.This behavior is turned on with a configuration choice, "ATU HiSWR RETUNE". After the training session, I tune across the band and change antennas as I wish, and the pre-tuned ATU settings are determined in a few tens of milliseconds. I don't press any buttons to cause ATU tuning, once I've asked the KPA1500 to memorize the ATU settings for my set of antennas. The KPA1500's amplifier is bypassed when it needs to be for ATU tuning. We can't hot-switch the ATU relays at full amplifier power. ATU tuning is done at exciter power, usually around 20-50 watts, although 100W isn't too much for the relays. If I get to a new frequency that I've never tuned for, I have to press the KPA1500 ATU TUNE button. I have a keying cable connected between the KPA1500 and K3 "straight key" input that allows the KPA1500 to key the K3S when it needs carrier to tune the ATU. We're working on a signal between KPA1500 and K3S on the ACC connector that will hopefully remove the need for that extra keying cable. If this is as clear as mud, send me another note... 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Jason Pecora Sent: Monday, March 26, 2018 14:55 To: elecraft@mailman.qth.net Subject: [Elecraft] KPA1500 questions...

Re: [Elecraft] KPA1500 questions...
Jason, the short answer is that when the KPA1500 and K3S (or K3) are connected via the KPAK3AUX cable and your K3S config menu is set to "power per band" the K3S will memorize two separate power settings per band .. one which kicks in when the amp is set to "STBY" and the other when and the mode switch is changed to "OPER" Don, N5LZ -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jason Pecora Sent: Monday, March 26, 2018 3:55 PM To: elecraft@mailman.qth.net Subject: [Elecraft] KPA1500 questions...

[Elecraft] KPA1500 questions
1) Can the KPA1500 be placed on top of the power supply for those of us without floor space? 2) What is the drive power required for full output? 3) Can a KXPA100 be used to drive it thereby (gulp) giving us a 1500W KX2 or KX3 (or K2 with key line mod)? 4) Will it cope with digital modes at full power for sustained operation (like the KPA500)? My apologies if these questions have been answered, I have carefully gone over the available information. 73 and Holy Moly Eric WD6DBM Sent on my Samsung Galaxy S® 6. __ 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 Message delivered to arch...@mail-archive.com
