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.
LA1185 FM receiver
RF amplifier, mixer, local oscillator
Improvement in cross modulation characteristics due to the use of double-balanced mixer
Improvement in strong input characteristic
Minimum number of external parts required
Less spurious radiation from local oscillator
Operating voltage range : 1.5 to 8.0 V
