MAC and IOS apps for Control of the Elecraft K4

Like most Apple software, K-4 Control is both innovative and intuitive. It is also easy to learn and use. You are definitely not looking at a long learning curve with these apps. A good example is the FT8/FT4 mode which makes operating those digital modes both simple and foolproof. No audio drivers or settings required. You will be up and running FT8 contacts in a few minutes. I started with the MAC app several months ago and was so pleased I got myself an iPad for more flexibility. When I ran into a connection problem support by Marcus was prompt and unstinting. You will NOT be abandoned. Highly recommended.

The Best

Marcus never fails us to bring another outstanding remote app. Works seamlessly with the K4D.

Outstanding as usual!

I have owned Marcus’s apps for the Flex 6400 Radio for iOS , iPadOS and macOS before. His MacOS app is much better than Flex’s in-house Windows app. Now I have a K4D and first day on the iPadOS version and Marcus does not disappoint. He is an amazing developer. I highly recommend this app.

Highly Recommended

Really appreciate what a fine product this app is. Had a few questions on getting Remote to work from outside of my home’s LAN. The support and assistance I received from this app’s support team was absolutely excellent.
