• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Pro 84 vs. Pro 97

I own both of these scanners. They have the same frequencies stored in them with the exception of the trunking frequencies. One day I was monitoring with both of them on. I noticed that the 84 was picking things up the 97 wasnt. For instance; DuComm Fire East and West will come in clearer on the 84 then the 97. Also I seem not to get anything from CFD or CPD on the 97, but it will come in clear as day on the 84. I am in DuPage county. I have tried adjusting the squelch but nothing happens. Both scanners are stock.

I own a Pro-83 (similar scanner) and the Pro-97. This is totally natural. Each scanner is a bit different and more or less sensitive on some bands then the other scanner. They may not be exactly the same in receiving the same frequencies. Also the Pro-83/84 is a smaller scanner and the speaker doesn't produce as much hiss as the Pro-97 so "clearer" signals may just sound better because of the speaker. I assume both of your scanner are in the same location to test this. In my case, the Pro-83 is a bit weaker in receiving freqs than my Pro-97. But like I said, things will differ depending on each individual scanner. But there shouldn't be a huge difference.

All the scanners I have listed below receive differently just as you've experienced with your 2. Some designs are better are rejecting signals on adjacent frequencies, some are better with weak signals, .. and some are not good at anything. I'm pretty sure if you have 2 TVs, both hooked to an antenna; or 2 AM or FM broadcast radios; or 2 ...; you'll find the same thing. Heck, even 2 of the same model might not receive the same.
