K1 power output question
 
|
Hi folks:
Just finished a 4-band k1, and thought I had low power out on all bands. Turns out the cable from rig to meter was open on the ground side (a cable Xperts cord). At 5 W requested, I now get 5 w on 20, 30, and 40 meters, and about 4-4.5 on 15. A 7 watts requested (the maximum on the menu), I get approximately 7 on all bands but 15, where I get 6W. Is this normal for a K1, or should I do some tweaking somewhere (where?). By the way, my 'ol K2 3854 just logged its 101st country at 5 W on a 65' carolina wondom. 73, Ted WB3AVD _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Ted,
That is about normal for a good K1. 5 watts or more on all bands is to be expected - most will do more. 73, Don W3FPR Ted Holland wrote: > Hi folks: > Just finished a 4-band k1, and thought I had low power out on all > bands.

I will echo what was already mentioned. Your measurements are about the same as what I get on my K1. 15 meters has always been a bit lower than the other bands.
One other thing I have noticed is that the power readout on the K1 is not linear across the bands. I checked mine with a fairly accurate QRP wattmeter. If you align the power meter on the K1 so that it accurately measures 5 watts on 40 meters, it will read a little high on 15 meters and visa-versa. I set mine to be spot-on at 20 meters and it is close enough now on all the bands. Have fun! John, WA6L

Does your unit have the ATU in it? The problem may be your antenna. The
power meter in the unit is less accurate for higher SWR values unless you have the ATU then the rf meter on that board replaces the poor mans rf detect in the K1. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of WA6L Sent: Monday, January 28, 2008 1:06 PM To: [hidden email] Subject: Re: [Elecraft] K1 power output question I will echo what was already mentioned.
