14,068 Mhz bilateral transmitter
Some MOSFET's BS170 requires a resistance from source to gate. It should be approx.3kOhm and needed to be individually selected. Coils on ring T37-6 are tuned for resonance , then TX signal is clear.Output power is abt 50mW ,if my power meter shows correctly. It easily lights LED , telegraphing tone also is clear.

I have the experience to build an antenna in snow and I know that hot coffee cup is equally important as the antenna mast. I went to the nearest store and did not get the required alcohol,so I bought the kerosene and Grant's Scotch whiskey. I remembered the good old oil lamps principle,and made a stove. It should be three-wick, the faster heats the water, wicks should be made of natural linen, or wool.Grant's in case the lack of fuel, the best Grant's pour not into a lamp...warming-up guaranteed...
