[Elecraft] K4 and K3 - Sherwood Report

I agree with Igor, since neither the K4 and K4D have roofing filters their performance probably won't equal that of a K3S with a narrow roofing filter in some contest environments. Therefore, I'm hoping to keep my K3S in operation long-term.  I realize this is a long shot, but after Elecraft

Re: [Elecraft] KX-3/KXPA100 for multi-multi contesting?

Drew, KX3 is not the best radio for multi-multi environment. The radio automatically protects itself by switching preamp off if 59+20 signal appears on the band. With even stronger adjacent signal the radio engages attenuation. Blocking dynamic range of the radio is not for multi-multi. You

Drew I suspect the issue is not so much with the KX3 assuming smart deployment and separation but rather with the brand of your other station’s rigs. As you already know, I was possibly with one of them and my biggest issue (using a K3s) was the CW “thumping” I heard. When I built and ran my

Anyone try a KX-3/KXPA100 for multi-multi HF contesting like Field Day? How does the RX hold up with loud signals on other bands? Plan to run external band pass filters of course. The KX-3 is so great at everything else. And it's great for single op HF contesting. Just wondering if it will

I had great success with an RF Concepts brick for quite a few years. Not made anymore but are for sale frequently. Receive preamp worked well too. I had the RFC2-417 which is supposed to be 170w out for 40w in, but got quite a lot of power driven by an HT. They have a few configs like RFC2-23

Can anyone recommend a good 2 meter PA for use with a KX3? I’m not looking to spend a king’s ransom, but I am leery of blindly buying an “unknown off-shore branded” unit. Being paired with a KX3 it would need to be portable (or at least luggable) and powered by 12 VDC. 30, 40, 50 watts or

You no longer have knobs, but the computer sound card controls and the digital app of your choice give you control of levels.  Use VOX in the radio and you won't know the difference, except for having a better sound card. Wes  N7WS On 6/1/2021 4:38 AM, Jim Leder wrote: I have an older K3

I have an older K3 and have been using a USB Signalink for digital. The audio levels are easy to control with the TX and RX pots on the Signalink. With the KIO3B installed, putting the soundcard inside the K3, how are those levels controlled? I ordered the upgrade kit, but need to know about
