Hello All,

I have a K3S which is exhibiting distorted modulation of the PA module.
Using the P3 TX Monitor 0 to 12 watts is fine, anything over 12 watts which
uses the 100w PA module is weak and distorted modulation, this has been
confirmed on air and with a second receiver. My setup is quite standard,
using a magnetic loop antenna with its own ATU. Transmitting into a dummy
load shows the same symptoms. Any ideas?

Thanks, Best regards,

Richard (2E0EFS).

Call Elecraft they had to replace mine on 10858 (100 Watt PA) and solved the problem.  I had the same issues as you as well.  I changed out coaxes and everything I could think of before I called service.  They called me back and said it was the 100 watt PA board and send it too them.  ALL is well….

HI,

thats what I thought; however I would have figured they would be a bit more robust?

Thanks.

If it is like mine was, it's a blown FET, or so Elecraft said. That diagnosis was a little puzzling since AFAIK it was making full power although I usually use the KPA500, so maybe I didn't notice.

That's not a bug, it's a feature.

And it's configurable in the P3's SVGA menu, something like 'Wfall Mkrs'...

Greetings all,

I would like to program PF1 to toggle the output power between say 30 and 100 watts.  Cranking the power down for digital modes would be so much  more convenient.  Is there someone who has done this and if so would you mind sharing the setting process?

To elaborate, even with the door to the shack closed I easily get distracted by a vacuum in the other room, rain hitting the roof and/windows, dog barking at the front door, kids and their music, XYL complaining that it is getting close to dinner, etc., the Bose helps extensively for me to hear the DX calling.

Don't forget about the power supply, radio, computer and amp fans running in the shack right at the operators position. You would be surprised at how much that seemingly light hum and hiss will cancel out (yes, even with regular headphones on).

Re: K3 Noise Cancelling Headphones - Experience?

n7wy
 

About 5 years ago, I researched on the web the comparative ambient noise reduction of then available headphones.  Consensus was that Beats Studio beat Bose Quiet Comfort; both are over the ear style headphones.   So, I bought Beats Studio with 3.5mm cabling, and some AAA batteries.  I was disappointed in the 3.5mm to 1/4 inch adapter, and bought a different one.  The pair of batteries are consumed in about 8 hours, and when they die, the headphones are dead.  The active elements of the noise cancellation were susceptible to RF, particularly on 15m at my MO QTH.  They are resting on the shelf in their attractive carry case.

A couple of years ago, I bought Monoprice noise cancelling headphones on-line for about $105.  No problems with RF susceptibility, they consume a single AAA in about a week, and they are far superior WRT Beats Studio noise suppression.  They do work without batteries, but with the battery power on, there is some audio gain, and suddenly my alpha 87a is silenced.
