I typically run my two feeds to Broadcastify AND eleven private feeds across several computers.
I've been doing that for 15 years or more.
There are several ways to do it.
Here's what I use.
I log all of the private feeds using ScanRec Pro. (may be hard to find now)
ScanRec records all of the alpha tags (with DMA scanners) and I have it set up to break the log files up every hour, on the hour.
Each of my computers has 8 TB or more of hard drives plus I share another 16 TB on my private home LAN.
I usually save the log files for each scanner, for a year or more.
Then I use Windows Grep to search the files for all occurrences of specific frequencies etc..
Two of the private feeds are full remote control using the RemoteFS app from my Android phone.
Using FreeScan Server on ports 1303 and 1305.
If you set up one, you know how to set up all of them.
Each is fed using an instance of ScannerCast.
They all use a Uniden DMA scanner. (BCD396*, BCT15*, and BCD996*, etc.)
