MW transmitter under constuction in May 2004. It was
first time in use Finnish Ham Summer Camp 2004. Behind
transmitter there are test equipments, i.e. 1kw dummy
load, directional coupler and spectrume analysator.
PLL oscillator bases schematics from Medium Wave Alliance webpages. It was
used by CMOS circuits 4060, 4046 and 40103. PLL covers MW
band totally. Fairly old-fashioned connection but it
still works. Reference PLL crystal is ovened to reach
sufficed frequency stability.
