KXPA100 with PX3
Locked

|
I've been using the PX3 with my KX3 for a year now, with no problems. I've now added a KXPA100, and find that either I can have full functionality of the amplifier, or of the panadaptor, but not both at the same time.
I've set up the system for full functionality of the PX3 and "Basic" operation of the KXPA100, using the ACC2 port on the KX3. That works OK, but I'd like to have full use of the KXPA100's interaction with the KX3, without losing full use of the PX3. The issue seems to be that they cannot share use of ACC1. Anybody have a solution? 73 Ray W2RS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Hi Dick,
When I tried that, I got no output from the KXPA100 with the KX3 PA MODE set to ON. If I set that to OFF, I get full output but then not full interaction with the KX3.

The KX3 says it has the KXPA100 behind it, but I still get no output. When I turn PA MODE to OFF, and turn the amp ON using the front panel switch, I get full output but in Basic mode.

Ray,
Check to be certain the RJ-45 connectors are fully plugged in. Some of them are difficult to seat if you hold onto the cover boot. Pull the boot back and push the plug itself in until it clicks. Make sure the other plugs are fully seated - give them an extra push into their jacks. 73, Don W3FPR On 12/30/2016 11:50 AM, Ray W2RS via Elecraft wrote: > The KX3 says it has the KXPA100 behind it, but I still get no output.

You may simply have the power set too low (below 11W) for the KXPA100 to turn on.

How are you turning the KX3 and KXPA100 on and off. If you shut down the power supply with the KX3 powered on, it will default to PA off and power our <10 watts and stay that way until you manually go back and turn PA on and change power level on KX3 to require the amp to be on. You should control the KX3 and KXPA100 power via the power on /off sequence on the KX3.

Further to my last email, when I am in Basic mode, with PA MODE set to OFF and the KXPA100 on/off switch set to ON, I get full power out and no dissipation. When PA MODE is ON and the on/off switch set to OFF, the KX3 acts like the KXPA100 is connected to it but there is no power output from the KXPA100 but all the power it produces is being dissipated. Some setting is probably wrong, but I can't figure out which one.
Any ideas? 73 Ray W2RS -----Original Message----- From: Dave AD6A <[hidden email]>with To: donwilh <[hidden email]> Cc: rsoifer1 <[hidden email]>; fcady <[hidden email]>; ai6do <[hidden email]>; elecraft <[hidden email]> Sent: Fri, Dec 30, 2016 10:39 am Subject: Re: [Elecraft] KXPA100 with PX3 You may simply have the power set too low (below 11W) for the KXPA100 to turn on. 73 Dave AD6A Sent from my iPhone 5s > On Dec 30, 2016, at 9:22 AM, Don Wilhelm <[hidden email]> wrote: > > Ray, > > Check to be certain the RJ-45 connectors are fully plugged in.

I'd suggest checking the ACC2 IO setting in the KX3 to make sure Tx keying isn't being inhibited. It's also possible that the interface cable is faulty. There's also the usual advice to make sure the firmware is current. My club's KX3 and KXPA100 were very unreliable until I updated their 2-3 year old firmware. Mostly intermittent problems with the ATU and even recognizing they're connected, but all that went away with fresh firmware. 73, Ryan AI6DO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Ray,
Does the power light on the KXPA100 turn on when you power on the KX3? I am not sure about your statements about "all the power it produces is being dissipated" Dissipated where? Into power output or into heat? Does the heatsink heat up? Similarly, your statement about "no power dissipated" when in basic mode. Can you connect an external wattmeter and a dummy load, put the KXAT100 into bypass and see what the KXPA100 is really producing. That more detailed information will aid in answering your question. If you can measure the current draw and voltage during keydown that would help even more. 73, Don W3FPR On 12/30/2016 3:16 PM, [hidden email] wrote: > Further to my last email, when I am in Basic mode, with PA MODE set to > OFF and the KXPA100 on/off switch set to ON, I get full power out and > no dissipation.

Yes, the power light is on. When I'm in Basic mode (PA MODE OFF), the KXPA100 draws 12 amps key down at 13 VDC. The power output is 100 watts. With PA MODE ON, there is no output and the current drawn is 8 amps at 13 VDC. The power is dissipated through the heat sink.

Don and others,
The good news is that you were right: the RJ-45 connectors in the control cable were not making good contact. I fixed that and PA ON operation of the KXPA100 is now working. The bad news, however, is that in Basic operation with PA OFF, the KX3/KXPA100 puts out full power, but the most I can get out of it with PA ON is 50-60 watts. The attenuator is set for OUT/AUTO and there is no more than 1 or 2 watts reflected power. What should I try now? 73 Ray W2RS -----Original Message----- From: Don Wilhelm <[hidden email]> To: rsoifer1 <[hidden email]>; fcady <[hidden email]>; ai6do <[hidden email]> Cc: elecraft <[hidden email]> Sent: Fri, Dec 30, 2016 10:23 am Subject: Re: [Elecraft] KXPA100 with PX3 Ray, Check to be certain the RJ-45 connectors are fully plugged in.

Ray,
Have you tried running the TX Gain Calibration on the KX3? It may be that the KX3 wattmeter is not well calibrated. If you do the TX Gain Calibration manually, it must be done on each band. The KX3 Utility automates the process. 73, Don W3FPR On 1/2/2017 11:55 AM, [hidden email] wrote: > Don and others, > > The good news is that you were right: the RJ-45 connectors in the > control cable were not making good contact.

Hi Don,
I tried that but an external wattmeter confirmed the KXPA100 forward and reflected power readings. Something in the KX3 is holding down the power output when PA is ON, but not when PA is off. 73 Ray W2RS -----Original Message----- From: Don Wilhelm <[hidden email]> To: rsoifer1 <[hidden email]> Cc: elecraft <[hidden email]> Sent: Mon, Jan 2, 2017 10:33 am Subject: Re: [Elecraft] KXPA100 with PX3 Ray, Have you tried running the TX Gain Calibration on the KX3?
