1000-P6

The General Radio 1000-P6 Crystal Diode Modulator was introduced in Catalog M (1951) and remained available through Catalog R (1963).

The Type 1000-P6 is an AM modulator accessory for oscillator frequencies between 20 and 1000 MHz. It uses a 1N21B microwave diode modulator which can be biased up to 4 V maximum, a 1.5 V battery or 0 to 4 V power supply is recommended. The modulated oscillator output must be kept below 50 mV to avoid damaging the diode. The 1000-P6 is useful for wide-band modulation where incidental FM must be negligible.
