CB gateway update

I placed the order for the CB gateway radio this morning, and it should be here by the end of the week at which time testing and audio calibration (into a dummy load) will begin.

The radio is the TTI TCB-550, a very basic radio with a small profile.  This will be bolted next to my current home CB radio, the autokey unit is located under the desk and already plugged into the computer.

The radio will need some form of cooling as it will spend most of it’s time in transmit when it is in service, and have decided on a fan which will be on when the gateway radio’s power supply is on (it will be connected to the same power supply), I have found a suitable fan which will be installed in place of the speaker.  The speaker, unusually is fitted to the board inside these radios with a plug/socket arrangement as opposed to the normal soldered-on connection, though if the current run of TCB-550s has had this changed I will probably desolder at the speaker and insulate the wires.

As soon as I have the radio and can test it, I will update this and the gateway website, this is at
