Re: [Elecraft] KX-3 TX current draw?

I think 1.6:1 is high for that kind of dummy load, if it's in good shape. Should be close to 1:1. Anyway, you can't really say there is a problem unless you have a better match. Current draw is sensitive to mismatch. -- Vic On May 9, 2020 2:32:15 AM GMT+03:00, Drew Arnett wrote: >Walter, >

Re: [Elecraft] KPA1500 and noise

Mine had noise on 80 meters. Elecraft sent me a load resistor to install in the power supply across the 50 VDC terminals. Knocked the birdies down to the noise floor. I also foo d there is a connection from the minus terminal to the chassis that was loose. Serial number 423 and it has been

Re: [Elecraft] KPA1500 and noise

I don't recall the details but have you read the posts by the Elecraft guys some weeks ago related to excess noise and loose grounding nuts (on or near the SO239 connectors if I recall correctly)? My KPA1500 creates a tiny amount of additional noise on 6 m when switched to "operate" but

Hi Ronnie I do not have a KPA1500 (only a KPA500) but I recall seeing posts from time to time about noise emanating from KPA1500's. I think you will need to check in with Elecraft on the issue. 73 Barry VK2BJ On Sat, 9 May 2020 at 10:28, wrote: > Recently I have noticed that I have a very

[Elecraft] KPA1500 and noise

Recently I have noticed that I have a very high noise lever at my QTH, which I have never had. Today as I was shutting down my station I turned off the KPA1500 first, and my noise dropped from S7 to S1 instantly. I turned the Amp back on and the noise came back. Have any of you ever

Re: [Elecraft] KX-3 TX current draw?

Hi Drew, I got 2.36A current consumption @ 5W using a dummy load and the TX button on 50.100MHz USB with my KX3 (S/N 3262). The voltage dropped from 13.74V to 13.67V during transmit. (Measured using an in-line Powerpole meter attached between a 54Ah LiFePO4 battery and the KX3.) Hopefully this

Re: [Elecraft] KX-3 TX current draw?

Walter, 50 MHz TX constant 4 W carrier measures 13.53 V on DMM (outside the DC power plug), 13.3 V on KX3 meter, 2.9 A on KX3 meter and 1.6 to 1 VSWR on KX3 meter. Microwave dummy load with BNC to N adapter. I didn't measure all of this when the rig was new, so have no baseline to know what is

Re: [Elecraft] KX-3 TX current draw?

What voltage? What frequency? It will pull more current at lower voltages. The power stages are less efficient at higher frequencies, especially 12m and up. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On May 8, 2020, at 4:19 PM, Drew Arnett wrote: > >

What do you see for current draw on the KX-3? Manual says 1 to 2 A typical. I'm seeing 3 A at less than full power on one band. Yikes! Makes me wonder if the repair shop is open? Elecraft website says hunkered down and mostly work from home. Thanks and best regards, Drew n7da

Re: [Elecraft] KPA500 Remote Software will not pin to STARTUP list

But when KPA500 Remote or KPA1500 Remote start up, you need to invoke the Start Hosting Remote function to get them to listen for a remote connection. It may be possible to automate that, but I don't know how. And if you could automate it, note that these Remote apps power up the amplifier as they

Re: [Elecraft] K3 current draw

Hi David; You can tap DISP and rotate VFO B knob to see the current. Then set "tun pwr" to nor, select desired power out, and long press XMIT to send a carrier and see the current. (do not TX at exactly 5 or 50w as that will cause a TX gain calibration). That will give you a close reading. The

Re: [Elecraft] KPA500 Remote Software will not pin to STARTUP list

Frank – Glad that helped. It’s a useful tool for any apps you always want so you gate get them started quickly without waiting around while the system goes thru its boot gyrations. I remember having to write batch files in early versions of Windows (and DOS …) to do the same thing.

IUnless you're in a multi-op or noisy environment, why go with bulky, heavy, over the ear models? I've used a Sony MDR-W08 for years. Appears that model is discontinued, but there are similar ones. It weighs 1 oz(!) and cost about $20 when I got them. Do a search and you'll find similar ones.
