Re: [Elecraft] KPA1500 Using Multiple Antennas With the Tuner

I agree, Dick - power settings per band are fine.  The issue is power settings per band and  per matching solution 73, Pete N4ZR Check out the Reverse Beacon Network at , now spotting RTTY activity worldwide. For spots, please use your favorite "retail" DX cluster. On

Re: [Elecraft] KPA1500 Using Multiple Antennas With the Tuner

Your K3 stores the power settings. The amp reports when it goes in and out of OPER and the K3 (and K4) store two power settings per band, one for the amp in STBY, another for amp in OPER. You adjust these levels at the exciter, and they’re retained for recall on band switch and power off/on.

Re: [Elecraft] KPA1500 Using Multiple Antennas With the Tuner

I too have the same issue. I worked with Dick on this, but there is no solution currently available when using an external antenna switch (necessary with more than two antennas) with the KPA1500. Unfortunately, there is no way for the KPA1500 to tell the K3/K3S to use a different drive level,

Re: [Elecraft] KPA1500 Using Multiple Antennas With the Tuner

Precisely what I thought, Jim.  The KPA-1500 already adjusts the K3's output power when the amp switches to OPER, from 100 watts in STBY to a preset, much lower value in OPER, but I don't know if they can store and recall drive power levels by band and antenna 73, Pete N4ZR Check out the

Bruce, You can set the KPA1500 to automatically go to STBY when you change bands.  Band Change > STBY:  YES. Jim __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm

[Elecraft] KPA1500 Using Multiple Antennas With the Tuner

Jim, Thanks for the info.  You understand the problem for sure.  Dick is being very helpful now, but I'm getting erratic data for him because switching between antennas sometimes only results in "NEED TUNE PWR" with OK result after a few seconds, and other times I get the fault due to

Re: [Elecraft] KPA1500 Using Multiple Antennas With the Tuner

Jim, If it is a manual switch then must be a short run from KPA to switch so why not connect to ANT1 ANT2 on KPA and switch with KPA. KPA stores separate solutions for each ANT. de Dave K5MWR On October 16, 2020 2:26:13 PM CDT, Jim McCook wrote: >Dave, yes, one coax from the amp to a manual

Dave, yes, one coax from the amp to a manual switch.  Your question is the same as mine.  Somehow the KPA1500 should know by sensing a rise in SWR and shutting down most of the drive power or output somehow so the tuner can go through its motions without excessive output or a fault.

Re: [Elecraft] KPA1500 Using Multiple Antennas With the Tuner

If I am reading this thread correctly you have one coax from the KPA feeding a remote antenna switch. If correct how do you expect the KPA to know you switched? de Dave K5MWR On October 16, 2020 1:54:02 PM CDT, Jim McCook wrote: >I meant to say the tuner settings were made with the KPA1500

I meant to say the tuner settings were made with the KPA1500 in STBY with the K3 TUNE PWR set to 40w.  Jim __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post:

I followed N4ZR’s thread and did not see a solution.I have the same problem as Pete.I’ve got two antennas on 3 bands.I’ve put the tuner settings in all the bins on those bands for each each antenna.Neither antenna has SWR over 2.5:1.I can then step through the bins with RF on each of those
