Well to start with loading current frequencies, I can still get some NHP even though they are edacs until they go to P25 phase 2.
When I run down to AZ to buy lotto the 7 and the 12 do pick up some AHP and a few local freq's but most of the pre-programmed ones are not in use.
I do have newer better scanners but I still like the old ones and I hate to see them sitting in boxes.
Many older radios cannot be upgraded due to the electronics. The ROM where the data is stored was only designed to handle a firmware file of what was known at the time of production, with a limited amount of additional memory for fixes and planned upgades. Other components just don't have the technology to handle the newer systems. My Pro 106 still does well on P25 trunked systems, but phase II will be the end of digital use.
I still find uses for the older scanners. I have (1) 895XLT doing nothing but MIL and civilian aviation, the second 895XLT does nothing but HAM on 6,2,440,1.25, 900 an such. I have a PRO-2096 and a PRO-96 still picking up digital simulcast on Phase 1 systems. And 2 GRE radios that were at the Whistler/GRE buyout era that do Phase 2. I can use the HAM only to track what is going on there, the aircraft radio for Military fly-by and regular traffic, and the rest for PD and fire. New phase 2 scanners are still around 298-400 dollars on sale. You might find a few on Ebay or if you use Picclick to search.
Always use older scanners in my shack for analog monitoring. I have a Pro-2035, a Pro-2051 and a BC895XLT that are dedicated to milair, aviation and hams. Also use a 2006 for various analog local stuff. The only thing I miss when it comes to those old scanners are Alpha-Tags. Egads. How did we survive without alpha-tags on a scanner?!
