Funny K4 Story
Locked
 
|
Last week Monday I received K4 SN0110. The Brown Truck came at about 2 PM.
That morning I had checked into an 80M net using my trusty K3. For 8)M is use an inverted V. All was well. Monday afternoon was a frenzy of setting up and using the new K4. Pretty easy setup. All week long I used the K4. All was good, but I was disappointed at signal strengths on 80M. I kept thinking that the K4 just couldn’t receive well on 80M! Yesterday I was out in the back doing yard work. That’s when I noticed that the support ropes on BOTH ends of the 80M inverted V had failed, and the the antenna was lying on the ground! We had had a storm come through here Monday mid-day, and my supposition is that the support ropes had failed. I restored the support ropes, and low and below the K4 works well on 80M again! I normally would have noticed the change in SWR, and realized that I had an antenna problem. But, of course, I had tuned the K4 for the first time on 80M when I received it! A learning moment (operator error?). Gonna try to check the antennas out a bit more frequently! 73, Tom W4KX ______________________________________________________________ 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] |

K3 #75

My K3 has a SWR display next to the RF Power meter in the Display.
So it Sounds like the K4 Does Not have that type of Display ?

The K4 shows all four TX bar graphs simultaneously: power, SWR, ALC, and compression. In addition you can select numeric display of power, SWR, supply voltage and current drain for the status area, which defaults to date/time.

I believe the SWR meter in the transceiver is at the input of the
internal tuner, not the output. Since it always reads close to 1:1 when the tuner is engaged you may not notice if the antenna has a high SWR.

This is correct.

On the assumption that the K4 antenna tuner has similar capabilities to the one in the K3/K3S, it can tune anything. An antenna lying on the ground is child's play for these tuners. Tom said that he hooked up his spiffy new K4 and tuned the antenna. No wonder he didn't see a bad SWR. :-) 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)348-7900 | services.

I have an external meter on each of my antenna feedlines so I know the
actual SWR for each antenna. Also see a difference in the reported power out on my (still) K3 versus the power reported on the external SWR/PWR meter.

With internal tuners on everything I have stopped using power/SWR meters on
my rigs. If you are matching your antenna before you get to the meter the meter just won't tell you anything useful. I suppose I could put one between the KPA500 and the KAT500 But I don't use it often and the KPA has the barograph meters as well as the digital display anyway.

I put my meters between my KAT500 and the antennas as wanted to see the
actual feedline SWR. Both my K3 and my KPA500 let me know if the KAT500 is not able to match ( and of course the LED display on the KAT500). 73, tom w7sua On 5/18/2021 4:45 PM, Jim Rhodes wrote: > With internal tuners on everything I have stopped using power/SWR meters > on my rigs.

Well a meter calibrated for a 50 ohm system will give you a relative
indication, but accuracy will vary with the actual VSWR on the line. The further off of 50 ohms the less accurate it will be.

In reply to this post by Alan Bloom
I have an external meter on each of my antenna feedlines so I know the
actual SWR for each antenna. Also see a difference in the reported power out on my (still) K3 versus the power reported on the external SWR/PWR meter which is to be expected given the line impeadance for my antennas is not 50 Ohms resistive. Will likely pick up a vector power/SWR meter to get a better view of my antennas.
