Re: [Elecraft] KAT3 problem
Barry, I had the same thing here a few weeks ago. I found that I had no output from my LPA board. It is now at Elecraft being serviced but I have yet to hear the final resolution. It has only been in service for a week or so. I used a scope and did some signal tracing and found that I had RF on the input of the LPA board and a logical HI on the 7T line. But I had no output from the LPA itself. I worked with support and we determined that something was probably wrong with the board itself. I removed it and sent it in. I found this doing the same thing - tuning up and only had two dashes on my display. Hope this helps. 73, Dave W8FGU On 7/7/2012 1:53 AM, Barry Garratt wrote: When I hit the ATU TUNE button this evening the tuner sounded like it was doing something but instead of the usual display of VSWR as it tuned there were only two dash lines.

[Elecraft] KAT3 problem?
My K3 is only 4 days old so I am still becoming familiar with it and the controls and I still have a big smile on my face! It is 100W unit with KAT3. I occasionally get HI SWR readings and have noted the following effects. 10W into 50 ohm load display shows 1.6:1 ATU bypassed, with the ATU tuned it SWR=2.2:1 My TH3jr has a 1:1 SWR at 14.160 with external SWR meter. The K3 shows 1.0:1 with ATU bypassed and 2.4:1 with ATU in circuit and tuned. Can anybody shine some light on this?

RE: KE7X RE: [Elecraft] KAT3 Problem
Thanks Gary, I redid the power calibration and the tuner tunes the dummy load all ok. It still struggled with the 40 dipole (native swr, as measured by the K3, is 1.6:1) and would only get a match of 1.4:1. But I put in a short length of coax as you suggested and now it can find a 1.1:1 match, although still with some struggle. No external switches, wattmeter etc. Thanks, Fred From: Gary Surrency [mailto:[EMAIL PROTECTED] Sent: Monday, September 29, 2008 2:43 PM To: [EMAIL PROTECTED] Subject: KE7X RE: [Elecraft] KAT3 Problem Hi Fred, Can you try a slightly different length of feedline to see if that helps the tuner find a better match? Just add or remove a length of coax if that is possible. Be sure the screws in the KAT3 and ANT1, ANT2 connectors are all very tight. Try a different ground connection too, and the K3 is connected as directly to the antenna as possible (no external antenna switches, SWR or wattmeters, etc.). Try lower power levels too (the tuner always uses 5w or less when it operates). Make sure the antenna and feedline has no bad connections, and use a SWR analyzer to check its match if you have one such as the MFJ-259B. If a powerful AM, FM, TV, or pager antenna is nearby, it might be affecting the tuner's operation on the antenna. -- 73, Gary AB7MY = [EMAIL PROTECTED] Elecraft Technical Support Hi, -Original Message- From: Cady, Fred [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] Date: Monday, Sep 29, 2008 6:28 am Subject: RE: [Elecraft] KAT3 Problem To: [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] Thanks Tom.

[Elecraft] KAT3 Problem
Hi, Just getting K3 going and KAT3 does not tune properly on 7 and 24 MHz. I'm pretty sure it worked earlier today on a 40 m dipole I put up but now it doesn't tune the dipole or a dummy load.

[Elecraft] KAT3 problem
It may be something I'm missing but I am unable to get more than 5 watts out in either ATU or Bypass with my KAT3 installed. It seems like it tunes and switches properly, just can't get 100W. Any help? Thanks, Julius Julius Fazekas N2WN Tennessee Contest Group TnQP http://www.tnqp.org/ Elecraft K2/100 #3311 Elecraft K2/100 #4455 Elecraft K3/100 #366 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KAT3 problem
Julius I think that is by design that it tunes at 5 watts to get a good matchso it can take the 100 watts into a properly tuned match. I think the tuner would have an issue at 100 watts at 4:1. But it doesn't have an issue a 5 watts. If you go to XMIT.after you run the tunerthen you will see the 100 watts output. Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
