I’ve made a few changes to the design of the transceiver. Changed the layout of the printed on the plate. Dodalem emisje CW. I added the emissions CW. Pressing PTT microphone transmitter runs in the SSB mode, pressing the key forces CW emissions at the same time blocking the track microphone. If you plan to construct a device SSB skip the numbers from 1 to 99 For the CW must be fully fill the plate and in addition, do less, for which there is a temporary arrangement remains uncovered broadcasting BK together with the control block, built on a CMOS system in 4093 and monitor broadcasting.
