On my ft-100 in the utv and a hustler 80 meter mobile vertical it's about 10 over near the source. Freq is 3900. But many other harmonics of the mix every 10 kHz, but 3900 is the loudest. I think I sent a you tube video of what I'm seeing a few weeks ago. Thanks....

I need to track down a broadcast station mixing problem, and seem to be
close to the source I think but unable to nail the location. Is there a direction finding solution others have used for 80 and 40 meters that worked
for them?    Thanks....Rich

Hello, Rich:

Nice Collins and Drake setups you have on QRZ.com.

When you say you are possibly "close" to the source, how close do you
mean?

The reason I ask is that if you are very close, you will need a rig with
a pretty good attenuator in conjunction with it.

Also, what frequencies are you specifically dealing with?
