I need
1.) The Commander Base Unit output impedance at the carrier ferquency? I think it is about 2MHz?
2.) The Locomotive input impedance at the carrier frequency?
3.) Verification of the Carrier frequency? I think it is about 2MHz, My O-scope Doesn't Have a cammera attachment/event capture mode.

Why?
Carrier is 3.27mhz, I can't say what the output or input impedances are.
Why?

John,
I replied to your E-mail.
This has been discussed in previous threads but note the MTH signal is not narrow-band like the Lionel 455 kHz signal. So when it comes to filter design you might find other filter characteristics such as constant group-delay which preserves digital timing in modulated signals may be more important than a sharp filter roll-off passing a specific frequency. Your mileage may vary. Just my 2 cents.
