[Elecraft] KAT3A Question
I have a K3S/10 with a few extra filters and the DVR board installed. I’d like to purchase the KAT3A automatic antenna tuner, but want to make sure that it can be installed in this 10w version of the K3S, or does it require the 100w option? Do you feel it is a nice addition to the rig? Are you pleased with the performance compared to other external ATUs on the market? Thanks in advance.

Re: [Elecraft] KXPA100 --> KX3/PX3 Question
Jim, Refer to page 9 of the PX3 manual. The system integrates nicely with the PX3CBL supplied with the PX3.

Re: [Elecraft] [KPA500] incredible hum from PA
Joe might be right but contact Tech Support first. The transformer is held in place with a single large bolt through the center (it is a torodial transformer). If that bolt is not tightened properly the magnetic field will produce a huge vibration. Even if you did not build the amp from the kit, it's a pretty simple job to tighten that bolt. Tech Support can lead you through the process. It is also described in the kit assembly manual available on the Elecraft web site here; http://www.elecraft.com/manual/E740149%20KPA500%20Kit%20Assembly%20Manual%20Rev%20F6.pdf See pages 36 and 37. 73, Ron AC7AC -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of W1GO (Joe) Sent: Monday, December 19, 2016 6:19 PM To: kevino z Cc: Elecraft Reflector Subject: Re: [Elecraft] [KPA500] incredible hum from PA Kevin, Yes. had the problem.

Re: [Elecraft] KX2 Memory Operation Question
I have not done any 60M operation on my KX3, but on my K3, I have the per-band memories on 60M set up for the channels, getting all 5 them by assigning the extra to VFO-B and swapping VFOs if necessary. I have had the problem of tuning off the DX frequency while groping for the knobs on the K3, so I got in the habit of using the (hold)-LOCK function to cover my tail. My KX3 does lock by holding the KHZ button for about 3 seconds. 73 Bill AE6JV On 12/19/16 at 11:24 AM, rfphe...@snet.net (rfphelps) wrote: I've had 16 years of Elecraft experience with the K2 and a bit less with the K1 and KX1 - then I added a KX2 last September!

Re: [Elecraft] KX2 Memory Operation Question
Dick, Look up "Channel Hopping" in the manual, that should help you with the KX2. If you plan to operate CW on 60 meters, you will have to add another set of memories that takes you to the channel center rather than to 1.5k below center as is used for USB mode. It is not available for the K1, K2 or KX1, but works for all the others. 73, Don W3FPR On 12/19/2016 2:24 PM, rfphelps wrote: I've had 16 years of Elecraft experience with the K2 and a bit less with the K1 and KX1 - then I added a KX2 last September!

Re: [Elecraft] Checking VFO accuracy using WWV
It is human nature to be disappointed if we don't get the nominal figure, but only the lower limit even if still within spec. We wouldn't complain if we got a few Watts more than the 100 Watts, and of course 100 Watts sounds like a lot more than 89 Watts just as $100 does to $89. 73 from David GM4JJJ > On 19 Dec 2016, at 08:12, Walter Underwood wrote: > > For the KXPA100, the tolerance is specified.
