[Elecraft] wanted: KAT3 Internal ATU for K3

Hi everyone, I am interested in purchasing a KAT3 internal ATU for my K3 and I was wondering if anyone had one available as a result of an upgrade that they are interested in selling. Of course, I will pay the postage costs and if payment via Paypal is ok I will cover any Paypal fee's too. Many

Re: [Elecraft] Equipment on top of K3?

Yes, that works fine, and it's how mine are mounted. I use velcro tabs to keep the P3 from sliding back -- I use the tilt-bale on the bottom of the K3 to place it at a good viewing and operating angle. 73, Jim K9YC On Fri,4/1/2016 5:46 PM, Mike Dodd wrote: it allowed to place the P3 on top of

[Elecraft] Oscillating Lab Power Supply

The other day, I was testing my new KX-1 with one of these power supplies: http://www.amazon.com/Mastech-HY3005D-Variable-Linear-Supply/dp/B000E14F56 It caused some awful garbage to come out of the KX-1, which was caused by the power supply oscillating and generating a bunch of 120 Hz ripple.

Re: [Elecraft] OT: Mobile operation "bible"

Actually Willis, there is no additional tuner.  Just the motor in the antenna and a single base matching coil.  I have put in a 15 turn airdux coil and use taps to set the best for 80 and up.  Works for me. Pictures on on file at several elecraft/antenna/mobile/HI-Q/ etc blogs. Anything in

[Elecraft] K3 Utility questions

I'm starting to explore other options with different software and my K3s. My main interest is in being able to send CW, RTTY and it would be a nice plus to send from the voice memories when calling in a pileup and not have to keep hitting the function button every time I put out my call.

LS, The most common problem with the thermistor board is a solder bridge on that board. One quick check is the voltage at U6 pin 5 which should be 1/2 of the 8 volt supply. Another check is to see if the voltage at U6 pin 1 is twice the voltage at pin 3. Those voltages will change as the VFO

Hi All, I think all the FCC code exams were plain text, not code groups--at least to my memory going back to the 50's. The reason may be obvious, in that the examiner had to check them "on the spot", and code groups would have been too difficult to check. I took the Extra Class exam in

All, The coax length doesn't matter because of the following reasons. Assuming the tuner is at the rig, there is a run of any coax to the antenna feed point, and you have a fairly high Q low band antenna that can't QSY much. With short HF mobile antennas that are high Q the reactance at the
