BG8AMG I'm using a version of Winkey that someone else created, and it actually has many very powerful features.
BI1SGB I like this device. Besides being able to switch the automatic keyer to only use hand-cranked keys, it can also be used as a CW practice tool when not connected to a radio. However, it only uses a buzzer and cannot adjust the volume or tone.
BH8ESR This means that it's possible to use a single key to simultaneously control two radio receivers (set in "hand-key mode"), and then seamlessly switch between the two receivers using the same keys? This would certainly be convenient.
