[Elecraft] Interesting observations after installing antenna switch

Hi all. I recently put a remote antenna switch in my HF system. This switch (a WA4MCM kit, RAAS-4a) is capable of reading band data from several radios, including my Elecraft K3S. For several years I have had a KPA-500 amplifier in line, working seamlessly with my K3S, band switching automatical

Hi Ray. Either I was unclear in my description, or it was mis-read. According to the display of the amplifier, it is ALWAYS set for the 60 meter band, regardless of what band I am actually operating. 73, Ken, KJ9B From: Ray Sent: Tuesday, August 29, 2023 3:06 PM To: ken.k...@gmail.co

[Elecraft] Digital mode power handling for KAT3

Hello. I recently bought a very nice K3 from a friend. It has the KAT3 auto-tuner installed. Due to the duty cycle of most digital modes, most, if not all, external auto tuners are "de-rated" for digital modes. I haven't been able to find any reference to this for the KAT3. Does anyone know th

Re: [Elecraft] K3 no transmitting

Make sure your K3 didn't get put in "Test" mode, shown by a flashing "TX" toward the right side of the display. 73, Ken, KJ9B -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Jorge Diez - CX6VM Sent: Friday, March 8, 2024 8:59 AM To: Howard K6IA Elecraft Support ; E

All the preliminary stuff starting with the icloud URL is icloud "protecting" you from opening what could be a suspect URL. Although in this case, if you look at the end of all that, you will see "IMG_0716.pdf". That is a PDF of what is in the package for sale. 73, Ken, KJ9B -Original Messa

Re: [Elecraft] K3 Power Issues

I'm not sure where the voltage displayed on the K3 is sampled, but I have found it to be consistently about a volt lower than the voltage present at the Power Pole connector on the back of the radio, especially when in transmit mode. I have found this to be the case on both the K3 I use for portab
