@jmorris I had a QEX subscription years ago but let it lapse due to it being paper only. I don't have room for magazines. I see now it *is* available digital only.
A recent article in QEX makes me want to either join ARRL or subscribe to QEX. I let my subscription to QEX lapse a few years ago because I prefer digital copies (PDF)
