Voice keyer ( CQ parrot )

Calling cq in ssb with only 5 Watt can cause a sore throat....
Although in production for severall yaers this exellent kit BX-184 from Box 73 is still a must have for the QRP operator. Link
Easy to build high quality kit that provides 60 seconds voice recording and a strong punch to the modulation . I had to reduce the mic. gain to 25% on ssb and 15 % on fm/am at the FT-817.
This kit is also available with a extra MH-31 type mic. enabeling the use at other transceivers with 5V or more at the mic. cable. The red dot marks the fst button that controlles the functions,
