Special design!
Digital scale for hamradio Receiver kit CW / SSB 20/80 m
Main features:
The main differences and excellent opportunities - toset the value of the intermediate frequency reception with high accuracy foroption
1 intermediate frequency is higher than the receptionfrequency
2 intermediate frequency lower than the frequency ofreception
3 is capable of operating in conjunction with thedigital frequency synthesizer (direct synthesis)
65MHz frequencyto Microchip, PIC16F628A as the core.Ø
frequencyreference with temperature compensation type voltage controlled crystaloscillator (2.5 ppm VC-TCXO).Ø
adopts gatecontrol mode and the accurate time algorithm is unique.Ø
gate (refresh)time of 0.1 seconds, real-time display of frequency.Ø
The precision of frequency measurement by 10Hz/100Hz(the right one) optional.
display driverusing the LED chip digital tube display, high brightness, less externalinterference.Ø
adopts six 0.56 inch digital tubedisplay, automatic blanking invalid zero, eight stage adjustable brightness.Ø
simple circuit,reasonable structure, double button control, simple operation.Ø
all settingsare automatically saved, boot directly type=\"disc\">
