[Heathkit] SB-610 Receive Pattern Amplification

[carl lowry]

Looking for a small circuit , perhaps an OP-AMP type which can be put inline
between the Receiver IF Output over to the Vertical RCA Input jack on the back
of the SB-610 which will increase the pattern height (enlarge) on the scope's CRT.
Has anyone come up with such a circuit or is any member making them ?
Thanks & Best of the Thanksgiving 73s
