AT-20 200W Attenuator Kit memory CW Keyer

memory CW Keyer

Can be directly connected to the RS-UV3 antenna jack

The circuit uses a NXP AFT09MS015N with a 4:1 output transformer which can develop over 7W with 13

The receiver in the RS-HFIQ consists of 5 band-pass filters to reject out-of-band signals
