Uh...
I was under the impression that the 610 / 614 monitor scopes were for 
monitoring the 'transmitted' signal.

kc?  you said 3meg(sic).  Which is it?

Sooooo...
I was under the impression that the 610 / 614 monitor scopes were for 
monitoring the 'transmitted' signal.  Since I wasn't sure, I went looking.

Heathkit SB-610
The Heathkit SB-610 monitor scope is primarily designed for monitor the 
RF-signals, on-the-air signals, from the local transmitter. It can also 
be used to monitor received signals when connected to a receiver.
It monitors RF-envelop, RF-trapezoid and RTTY pattern. SB-610 has also a 
built-in two-tone sinewave AF-oscillator for SSB-transmitter adjustment.

The Monitor-Scope matches the SB-line.
