[Elecraft] KPA1500 tuning

With KPA1500 amp in bypass, ATU in bypass, I put the K3's atu tuner inline, then pressed ATU TUNE on the K3.  The ATU in the KPA1500 started to tune, then faulted on 30m.  I don't want the KPA1500 doing anything on 30m.  Running beta fw 2.28.  Do I have a setting wrong, am I supposed to turn the

Re: [Elecraft] AE5X: 3D printed desktop rack for KX3/PX3

I don't have the PX3, but do often use the KXPA100 when portable. The last time I set it up I was kind of cramped for space so I just set the feet between the last 2 fins on the KXPA100 heat sink. Held it at an easy angle to see, so I left it that way for the rest of the portable op, a couple of

I have some of the stripes, although they are less pronounced with the KIO3B upgrade installed. And just checking I only see one at about 950 hz and a weaker one at about double that. At triple that it is very faint. I don't hear anything though so I have always assumed it was in the received

Rich, Online "answers" that are not K3 specific are often incorrect. You must drive the audio so that you have 4 bars shown on the ALC mater with the 5th bar flashing. That is the NO ALC point for the K3/K3S/KX3/KX2. Once you have achieved that condition, leave the audio level fixed and

Kevin, I don't think you can do that with a KX3 Utility configuration file. But you should be able to do it with Macros - look at the commands in the K3/KX3 Programmer's reference. An advantage of using Macros, is that they are stored in the KX3 and not in a computer file, so no worry about

Re: [Elecraft] KXPA100

Ed, The relays in the KXAT100 are not latching types, and the NC contact of the antenna selection relay defaults to ANT1. I can see a potential solution to your problem since you have 1 port of the external SP4T relay not connected - put that relay on ANT1 and the 80/40 antenna on the

[Elecraft] Batch programming with KX3 Utility program?

Hello, My club is running a KX-3 with a Windows (7? something old and at end of life) workstation. I've installed the KX-3 Utility program and have used it successfully to program the radio and save the configuration. I recently wrote about using different headsets in place of the MH-3 mic.

Re: [Elecraft] KXPA100

Quick question. I have the KXAT100 installed which provides two antenna ports. It switches between fine, but I note that it defaults back to ANT1 when amp power is shut off on front panel. I have a 80/40m invert-V attached to ANT1 and a SP4T relay attached to ANT2. The relay permits

As to the beep every 7 seconds, I see that on my P3.  It is a tuneable signal in CW mode, however it does not appear when the antenna is disconnected from the radio.   Therefore, it would seem to be coming in on the antenna.    One of those UFO's, space aliens, or other one eyed monsters. 73

Re: [Elecraft] K2: KPA100 Trouble

Jim, Likely nothing wrong.  If the K2 is ever powered when that menu parameter (which follows the heatsink temperature) is set to a low value, the parameter will try to go below 0 degC - but the math cannot handle negative values, so it instead goes to a high value. It is wise to check the

Hi again Don, I just finished that. I found the setting to be 143C. something must be bad; possibly R6 or the temp sensor? So, I set it to the ambient temp (in C), and checked the current limit setting - it was correct at 3.50A. I toggled the power, and it's now working. Power out is OK, and

Most AA battery holders, because they are not designed for high current draw, have relatively high resistance, and you see a lot of voltage sage while transmitting. Elecraft has made an effort with their internal AA cell holder in the KX3 to mitigate this problem, but every external multicell AA
