What's New in Version 1.2

** New in version 1.2. Interim release. I'm still working on a major update, but I wanted to get this out quickly to fix a major issue that showed up with iOS 8. Changes in this version:

-- iOS 8 compatibility. Fixed a bug that causes the text display to go crazy. However, iOS 6 (or higher) is now required.
-- Different screen sizes are now supported
-- Macros now work on the input line as well as in macros.
-- iPad version includes \S for QSO macro.

Customer Reviews

Works fine good deal!

I just installed on my iPad and tried with my FT-817ND radio through an interface. No issues with connecting and I had a QSO right away. Nice add to my portable. The iPad is much easier to take with compared to a laptop that dies after a few hours of use! Great job and hope to see you programming again soon!

Audio tx issue with direct connect

This app has an audio TX issue with direct connect to certain interfaces. The RX works fine. I initially thought it was the interface but have confirmed other apps work just fine.
Hoping the author corrects this quickly as this is an important issue for many users.

Great app!

So far I’ve used this running on an iPad 2 connected to a Yaesu FT-817ND, connected with a KF5INZ Easy Digi interface. PSKer decodes BPSK-31 well. I’ve tried it acoustically coupled to the rig but the physical interface makes decoding and sending more accurate, in my experience.

Nice features to have in future versions would be:

—More macros to reduce the amount of typing required on a phone or tablet.
—Larger send buffer that can hold more than 1 line of text.
—QPSK-31 capability.
—I would really like to see someone make an iOS app that can send and decode MT-63.
