Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Out of Band IM Analysis

I thought I'd ask this question.
I am conducting some out of Band IM analysis for a site that has some 800 MHz, UHF and VHF transmitters and I am seeing lots of hits on the UHF and the VHF channels. I know that these are theorethical hits and that most of them would look like noise.
Does it make sense to analyze all 3 bands together or should I look only at the In-Band IM ?

If by IM you mean intermodulations, the only crucial ones are those appearing in the in-band.
The others will be anyway much lower and can't disturb the signal.
