RE: OS Minitron 12 channel reed
Thank you for posting this, MeowJPN. It brings back many memories. I had never seen an OS reed radio, but it appears to be of very advanced design compared to the reed radios with which I was familiar.
The transmitter is no doubt capable of "simultaneous" operation of some channels. If you wish, you may apply rudder and elevator control at the same. If I am correct, you will hear two reeds vibrating at the same time. The simultaneous sending of two tones has a very unique sound.
