Pro-668 scanning issues

[Motorolaguru]

Hello! I have a Pro-668 and I recently programmed it to scan one of my local digital systems (Type II Smart zone) and when it’s scanning it will lock on to a TG but I will not hear any audio, every now and then I will hear audio but 90% of the time I do not. I know the TG’s are not encrypted because I have my 436 scanning them along with it and it gets them perfectly fine. Any suggestions?

Which system? Can you provide a link? Has your 668 had the Whistler Legacy Upgrade. Please attach your iSCAN or EZ Scan programming file so I can take a look at it.

My guess is it is a simulcast issue if you are listening to the Winston/Salem Forsyth tower, the Radio Shack PRO668 and Whistler scanners do a terrible job with simulcast systems. Try moving it to a different location or take it out with you and see if it improves any, with simulcast location can be a major factor.

That was my guess as it got stokes county which is viper perfectly fine.

My PRO66 upgraded to WS1080 works great on the Cary/Wake P25 Simulcast system at home, but terrible a 1/4 mile away, while working great on Viper towers local to me.

No I haven’t done the upgrade as this was given to me and I have other scanners that I mainly use and this was kind of a side project. How could I attach the file? I don't see an option to in the programming software?

In the Radio Shack PRO-668 iSCAN programming software, take the configuration you use to program the scanner and save it to archive. Click on Attach files on your post and open the archive file.

When I try to do that I get this error

Go to FILE tab, scroll down to SAVE TO ARCHIVE, archive configuration, that will create a zip file you can attach depending how big the your programming is.

Yeah that's what I did and when I click save when it makes the file it gives me that error.

Since I can't get it to work here some screen shots of what I have programmed, if you need to see something else let me know!

That was @tvengr requesting the info.

Simulcast
there is that nasty word.
even a change of weather might set it off.
try moving the radio, well really the antenna, it might help

Yeah simulcast is definitely a scanners worst nightmare, I might send it off to get the legacy upgrade as I’ve heard that can help and it would also be convenient to have an updated database.

I see 2 problems. First, you have only 2 of the 4 control channel capable frequencies. You need to add 853.275 and 853.675.

853.200c

853.5625c

853.275c

853.675c

Second, the system is using rebanded frequencies. You need to change Trunking Tables from Default to Custom. Click on Edit and enter this custom 800 MHz rebanded band plan.:

Table	Lo Chan	Hi Chan	Offset	Base	Step
0	440	559	440	851.025	25.0
1	0	719	0	851.0125	25.0
2	720	759	0	848.000	25.0
3	815	831	0	846.625	25.0
4	958	958	958	868.975	25.0
5	961	1022	0	843.400	25.0

Thank you! I'll try that out, the control channels I put in 2 sites to see if that would help any but I don't think it did.

 

[tvengr]

All 4 if the control channel capable frequencies should be in a single site.

Adding the re banded frequency's did help a lot! I'll put the control channels back into one site. Thank you for your help!!
