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

Itís 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.

Itís 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

For sale is a one of the many prototypes Corsette QRP AM transmitter I built.

Itís the design from Dave Martin's website.

Homebrew construction built on copper clad board housed in a tobacco tin with a HC49 socket for the crystal, BNC connector for antenna, phono connector for the audio and banana sockets for DC input with diode and fuse protection just incase of reserve dc connections.

Itís crystal controlled and runs off 12VDC and produces 500mW carrier.

Conditions on bands arenít great but tested it on air recently and was heard "weak to ok" over 300miles away. 

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

Also have a 6245.83KHz or 6436KHz crystal if needed to get you going (extra cost)

Please PM me for more details
