Eric, TX gain cal should work every time. You may have an issue with low gain in the 10 W or 100 W stage. 73, Wayne N6KR

Note that the K3's external ALC loop has a long time constant, by design, so it will not cause splatter or other bandwidth-hogging artifacts. It is intended to catch broken antennas or amplifier hard

Hi Dick, Is there any software that optionally applies a randomized +/- 20 Hz *TX* option for spot-clicks? If everyone used such a feature, the "dead-on" problem might slowly get better over time. Way

Sherwood has posted measurements of the K4D in his receiver performance table: http://www.sherweng.com/table.html We're quite pleased with his test results, which confirm that the K4/K4D is near the t

Hi Lou, The K2 uses RC exponential keying envelope shaping, typical of earlier analog superhets. The K3/K3S and all of our current transceivers use sigmoidal shaping in DSP, with coefficients hand-tun

We have plenty of K3 switch arrays in stock. 73, Wayne N6KR ----- Elecraft...Full-Contact Ham Radio www.elecraft.com QSO Today Ham Expo gold sponsor; March 13-14, 2021 www.qsotodayhamexpo.com

Sorry about that, John. Response is usually much faster. Someone will get back to you right away. Wayne N6KR ---- elecraft.com

All T/R switching in the K3 is via PIN diodes, not relays. But there are relays in the band-pass filters. These are only switched on band change, normally. Please contact support for troubleshooting s

Hi all, As you may know, Elecraft is a gold sponsor of the QSO Today Ham Expo this weekend. We'd love to have you drop by our booth. In addition to new video content, we'll have our product specialist

Every day, hams worldwide, young and old, summit mountains and hills carrying the lightest possible load. They earn every calorie burned, and are rewarded with vistas most people never see. Like all a

Definitely! That's what the KAT3A was designed for. (All of our radios embody the Spirit of Field Day, going back to the K2. That means working with crazy, ad-hoc antennas.) There are two ways to use

Given the number of requests we've received, we've decided to do another run of KAT3A modules for the K3/K3S. We have a small number in stock, ready to be shipped. Orders beyond that will be filled as

Hi Robert, If there were enough demand, we'd build another run of these. Wayne N6KR

I've had zero problems with APP connectors, in any application. They're an em-comm standard, and have been far less problematic than Molex or other connectors. We assemble them according to the manufa

Hi Andy, If you strike out, let me know. I may be able to scare up a spare KAT3A here at home. Wayne N6KR

FYI, it doesn’t include the bypass relay we added to the KAT3A. Wayne ---- elecraft.com

The k4 group has definitely not been closed. I’m guessing this was supposed to go there. Wayne N6KR ---- elecraft.com

As Eric alluded to, the entire Elecraft design team is safely working from home. We're busy adding new capabilities to the K4 and testing it in real-world conditions. (If it weren't for the lock-down,

Yes. Wayne N6KR ---- elecraft.com
