For sale is a one of the many prototypes experimental gate modulated Corsair AM transmitter I built.

It’s the design from Dave Martin's website.

Homebrew construction built on copper clad board housed in a diecast box with SO-239 connector for antenna, phono connector for the audio with volume pot. All connections mounted on the outside. DC input is bare wire (no connectors as I've run out) has diode and fuse protection just incase of reserve dc connections.

It’s crystal controlled and fitted with 6436KHz (HC49) and runs off 12VDC and produces 10w carrier.

Tested on the bench again (since it was last built) into a dummy load and working.

As mentioned this was a prototypes, Not saying anything is wrong with it just could do with finishing off ie Crystal holder, DC connections and maybe a fan on the outside . As the box was used for something else before it only has two screws for the lid.

Ideal for someone wanting to start out so open to sensible offers.

Please PM me for more details
