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

Here’s one way. You can send a string, say a letter ‘T’ (etc.) in CW mode with tone output only by embedding “<“ (RF off) and “>” (RF on) characters in a KYtext command. For example: KYW<T>; The ‘W’ f

Rob, What are you using as the stimulus for these tests? We'd like to reproduce this in our lab. Wayne N6KR

Still doing measurements, but it will be nominally similar to the K3, and better when optimized for minimum QSK delay. (In the K4, there’s no need to switch a synthesizer between transmit and receive

Yes. But if the signal is still too hot, it triggers the COR. Wayne

All RX antenna ports have series PIN diodes that open during TX. Wayne

I believe the excess fan noise problem was eliminated with a capacitor across the fan drive lines. There’s a mod kit for the K3. It should already be present in the K3S. There is of course a pedestal
