Hello, Having just completed the N2PK 20m/30m RXTXv6.2 daughter board, I tuned a bit L100 and C102 to be able swtich the output frequency to 40.5 MHz or 56.2 MHz according to the setting of jumper J100.
The output amplitude (peak to peak) is about 800mV for 56.2 MHz and about 1000 mV for 40.5 MHz for a load resistor of 5.6 kOhm. Is that o.k. or should the amplitude be higher (1.5V to 3.5V according to the builder notes)? (Note: If I remove the load resistor the amplitude values do not change.) Thank You! 73 Thomas, DF7TV
