A big dislike is the fact that, when the radio stops on an object when scanning, the display doesn't show the scan list. Son of a beep!
For example, instead of beginning "04-0215" as it does in manual mode, the first line begins "Scn0215" 'Scn' is totally useless information. I want to know the scan list.
For me this was about the very first thing I took care of in my own creative way, here is what solved this for me!
I very meticulously organized all my object ID's from the lowest "0" up to the highest object "1851" like this:
My 1st Scanlist is a TSYS I use object ID "100" and it's first TG starts with 101 and no higher than 199.
My 2nd Scanlist is a TSYS I use object ID "200" and it's first TG starts with 201 and no higher than 299.
My 3rd Scanlist uses the same TSYS as above, but a diff category so I use 301 and no higher than 399.
My 4th Scanlist uses the same TSYS as above, but a new category so I use 401 and no higher than 499.
(same kind of "Bank & Channel" scheme worked GREat .... ONLY until half way into my 18th Scanlist to 1851)
This is where some crafty and some simple creativity comes in handy. Le Me Explain ... por favor ....
I planned it out so that the 18th Scanlist was a smaller category so it did not need much ie 1801 thru 1851, etc.
Then Mo tricky on my part is that my 9th Scanlist was say VERY small in my case our News Media (901-910)
I stacked my 19th Scanlist object ID's ontop of my tiny Scanlist 9 ID's, so yep I used object ID's 911 through 999.
So for my last 20th Scanlist object ID's I used up the remaining 100 object ID's "0" through "99" etc.
How simple was that, my 1 thru 18 are cool, and in SL#19 hey what can I say ... at least my objects use 9's

Lastly SL20 are 0000 ~ 0099 ... I know the represent Scanlist 20 and don't care that they don's say 2001-2099.
Bottom Line: Like the guys example of lQQking at "Scn0215" during traffic ( You know it's Scanlist #2,15th item)
PS ~ You must either do some VERY creative object ID juggling and reassign object IDs in your PC program.
I did basically a ground up Scanlist Scheme planning it this way ~ ie think the good ol' Bank/CH scheme.
BTW ~ As the OP asked for our likes, dang this is the GREatest and by far my most favorite scanner I've owned!
My Pro-106 is almost 4 years old and I just recently replaced my "Keytop" membrane part because I
wore out my old one, changing this single RSU part ($13) makes my scanner look & feel brand new again!
My biggest LIKES are that if I miss ID'ing the last traffics freq and text tag, I can just press the "MAN" key !
With older scanners it's more like ... you snooze ~ you loose and or game over ... I Love this FEATURE

)
Next FAV feature is none other than the "FAV" key so I can just scan just the cool and or rare stuff I like !
On my older scanners to change listenning gears, I would have to hassle with turning on and off banks
and sub-bank trunking talkgroups and heck even resort to locking out things and darn trying to remember
just what I looked out .... grrr..... which dovetails right into my next favorite feature I call "soft lockouts"
This is a way way cool feature, if at any particular moment you really don't desire to listen to a freq or TG
or you simply would rather not miss the traffic you preffer to hear .... you just press L/Out and presto
it's history due to your mood, situation, location and RX signal quality and other factors that float your boat.
Later when any of the factors above change, simply cycle the power to restore your "soft" or temp L/Outs!
So my FAVS and Skywarn modes can also be used as your own Scanlists #21 & #22 if you so desire.
I like the custom LED ex: PD's=Blue, FD's=Red, SO's=Gold, Military=Green, Feds=Pink, Media=White.
Also, I assign the LED to flash for say Disp or CODE-3 and use Alerts to que me in on specials things tQQ
Man, the likes are endless, Virtual Folders, WOW and traffic Hit Counters, Audio Boost object toggle, etc.
The onboard Analyze capabilies I really find usefull, presto, what tone, LCN# and TSYS info & lots more !
I can use my Pro-106 as an "InLine" with Unitrunker, however, a factory Discriminator Tap is lacking.
Whew, OK the dislikes and they are VERY FEW, hmm battery drain and it would be helped out GREatly
by a dimmable LCD and Keyboard area LEDs ... I can loose the backlights and buy longer Batt tun time.
In the San Antonio area I can easliy fit everything into one load. However, as an example I have done
custom configuration loads for customers say in the Houston listenning area and heck their main TSYS
for Public Safety TRS has like over 2450 TG's so I can't import all that in one working Folder or Load
thank goodness many TG's can be tossed overboard but still MORE memory is needed for lager cities.
Also, I wish the Pro-106 supported EDACS Multi-Site like the Pro-107 iScan does, we have 8 sites in SA.
FINALLY if ANYBODY made it this far ... lol It would be wishing the Pro-106 had the menu option that the
original PSR-500 v1.0 had to toggle the monitor EDACS Encrypted TG's to Yes or No .. that way here
in EDACS "No-Voice" ... I mean "Pro-Voice" land I could easily monitor SAPD/BCSO with a simple
and portable "1 Scanner / 1 Laptop" solution. ie See the Alpha Tags on Scanner ~ hear audio on PC"
A huge thank you to the GREat guy that released DSD for WIndows ~ sQQn SDR/ $20 USB dongles
and a very robust laptop will make for a really lightweight and portable Pro-Voice monitoring solution
