Graph of 505DSP's TX audio response with 505ETX option installed. With a response extending from just under 100 Hz to approximately 4 kHz , this option lets you get those lows and highs missing from most other transceivers. And unlike competing models, opposite-sideband suppression and carrier rejection remain excellent. Our engineers have set another new standard for SSB performance. The most recent software on diskette is included.
Installation is simple.
