• 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:

I recently acquired a 4-port automatic serial data switch, labeled as MS-401. I can't figure out who the manufacturer is, and it came without a manual. The serial number sticker says that it was made in Taiwan. It requires 9VAC to operate and its basic functions seem to be OK - the lights come on, I can select the output, etc.

The problem is that this switch prevents communication between my computer and any of my serial devices - scanner programming cables, data slicers, packet modem, or whatever. I suspect that the problem could be solved by following the directions.

If anyone is familiar with this device and knows its secrets - or where I can find a manual for it - please let me know. I've tried searching, asking the used computer parts dealer where I got it, and asking local fellow hams.

That was helpful. Thanks. Now I just need to know how to get it to talk to non-printers. :)

I think I'm going to have to switch search engines. I've been using Alta Vista forever and it no longer seems to be very effective.
