It's not the first time we've made keyers.
Between 1981 and 1984 trading as Chris Moulding Radio Services we produced the CMOS VMOS Iambic Keyer.
We sold about 1000 keyers by mail order and at radio rallies in the north of England.
We still get enquiries for details of the original keyer and it's always good to hear how many are still in regular service 32 years on.
