The SB610 is a transmit monitor scope. It is not a bandscope. The model SB620 was a bandscope.
The SB610 is still very useful for monitoring your transmit signal through an amplifier for proper modulation and trapezoidal waveforms etc. Good luck finding parts. 73, Bob W5OV ex- "One of the Hams at Heath" > James I am not sure you will get value for money from an SB-610, they > date from the days when a decent oscilloscope was big and expensive. > These days 'scopes with the capabilities to monitor your peaks are > general purpose test items and don't cost much.
