Uh...
I was under the impression that the 610 / 614 monitor scopes were for
monitoring the 'transmitted' signal.
Some of them were built to work with the Heath receivers with the 3
meg IF and those that were built for 455 Kc. had the coils that would
do so.
If you find one for with the 3 Kc IF coils,
kc? you said 3meg(sic). Which is it?
it won't work properly with a NC 300 or NC 183D for example. Heath
packaged the coils for both with the units and the builder chose which
he wanted. I doubt you will receive the coils that were not used
during construction. Check them out before you find you have
something that won't work with your receiver.
Sooooo...

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.
