Introduction
Welcome to the Rooster. The Rooster is designed to be a single evening project that will be
fun to build and even more fun to use. The Rooster is intended to be a replacement for the
FOXX3 kit Kanga offered for many years. The FOXX3 was very popular but had a few issues
that we wanted to address with its replacement. We wanted a simple transceiver kit that
offered better sensitivity and selectivity, more power and a purpose made enclosure.
The Rooster was first offered at the RSGB convention in 2023 to beta testers and following
feedback the Rooster design was updated to this version.
The design is based around a standard SA/NE612 front end mixer/oscillator with an op-amp
audio amplifier and active audio filter. The transmitter also shares the NE612 oscillator and
buffers the VFO signal before feeding it to a high gain PA stage giving approx. 2 watts of RF.
The kit uses a mix of SMD and though hole parts, ALL the SMD parts are pre-installed but
still leaving about 20 parts to fit to complete the transceiver. The kit can be completed in
around an hour by an experienced builder and would be a good choice for an intermediate
level build-a-thon option.
The Rooster will require a suitable antenna with a low SWR, like all direct conversion
transceivers we would suggest it is powered by a 12V battery pack (10.5V-13.8V DC).
Disclaimer
The kit is designed to be built by Ham radio enthusiasts and in order to use the finished
product you need to hold a valid ham Radio licence that permits operation on the Rooster
frequency in your locality.
We offer the kit as is and do not guarantee the assembled kit by yourself can meet your local
regulatory requirements, including spurious, environmental or other requirements.
