Default Modulation on scope question

Vinnie;

Why don't you just try using another radio as the signal source? Run it in
to a dummy load. A loop or two around the dummy load may pick up enough
signal leakage that you can feed it in to the rig you're setting up.

A scope probe with 50 MHz bandwidth will be suficient. The bandwidth
of the probe is stated so that you will avoid attenuation issues at
high frequencies. Measurements above the rated bandwidth of the scope
probe will yield inaccurate measurement levels. If you are just
looking for the presence of a signal and the absolute level is not
needed then don't worry to much about the bandwidth of the scope
probe.

I just wanted to measure modulation on a TRC-455 that I am restoring. I
have a
10x probe with the bandwidth being 60Mhz in the 10x position.

But I have bad news. I apparently need and RF generator for alignment of
the
receiver. I do not own one. I have everything else. So off to ebay I go.
Any
recommendations?

Vinnie S.
