Hi all,

just a short update. Small transceiver modules can be used also as CW practice modules. 

When you connect Call pin with + VCC then module starts transmitting modulated signal which can be heard at a remote transceiver module on the same channel.

Hence you can use it as a CW practice module that is programmed on CB or PMR frequencies (for unlicenced radio operators) or on VHF or UHF channels.

Modules can be purchased in the shop here.
