Ham radio electronic kits
Ham radio links related to kit building projects. Many ham radio operators enjoy building transceivers, tuners, keyers, and other kits and homebrew projects.
K1EL Systems – Amateur Radio Kits and Projects
- K12 Keyer IC and Kit – The K12 replaces the very popular K10 and K10+ keyers which have been shipping for almost ten years now.
- K10+ Keyer IC – The K10+ is a Morse keyer I.C. with lots of built in features only found in high end keyer I.C.s.
- K-ID and K-ID2 – This chip is designed expressly for dedicated beacon or CW identifier applications. It is very flexible and has the advantage of a very large message storage bank (512 bytes) which is non-volatile.
