    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:

Hi all,
A small issue. I have a couple Pro-2050s. All work well, but I have noticed since one of our local depts went to a narrowband frequency (472.575), my ONE unit just seems to be off tune a little on that specific channel. it will stop on the channel without a problem, but the audio is low and distorted/off tune, It is obviously a internal tuning issue as I tried the same antennas on my other units and all work ok on those and that channel. I do not have the schematics for the 2050, but if anyone knows which coil/adjuster would do the trick, please let me know.

Unfortunately I doubt that it's a simple 'adjustment'; you're going to need a newer radio that will support narrowbanding. There are many inexpensive analog-only scanners out there, and most all the newer models can handle narrowbanding

best regards..Mike

Perhaps - did you search for a service manual? It's more likely with a scanner that old (it's the base model of the PRO-90 - the first RS trunktracker) that it's some component(s) that are beginning to go south.

Like I said, not likely to be a 'simple adjustment'...best regards..Mike
