WS1080: Tricking multi site theshold setting

[TAbirdman]

I remember reading that you have to duplicate a site so it will allow the "decode digital Threshold" setting adjustments to be active but I don't remember the other steps. Specifically what to do with the duplicate site ( scan list assignment etc)

For a 1080

Thanks

Johnnydollar2: I thought you had a trick to allow Multi site adjustment for a single site. I just couldn't find your post about it.

Import a system that has multiple sites into a scanlist.

After the import is done, go to the Trunked Radio Systems tab and click on the system your just imported.

Then, in the Site Details tab on the bottom left, lock out all but one site.

Then, click the Duplicate button on the top right.

Click on the new (duplicated) system at the top.

Then, in the Site Details tab on the bottom left, lock out all but one (different) site.

Then, go into the Talkgroup Details tab, click on any row and then Ctrl-A to highlight all rows.

Select a different scanlist on the right of the table.

Repeat as many times as necessary.


EDIT: Sorry - I may have misunderstood what you were trying to do -- what are you trying to do?

I use the EZScan Software with the 800 scanner. I am not sure if the Software for the 1080 is EXACTLY the same. With the EZScan Software there is NO "Duplicate Site" option. There is however, a "New" option, associated with the "Site List:" panel.

Does the 1080 Software actually have the word "Duplicate" just outside the upper right corner of the "Site List:" panel?

The site only has 1 location so the data decode threshold settings are grayed out. I remember reading that you duplicate the site which then allows access to the threshold settings but I don't remember what the other settings are.

But why do you want the thresholds to be available for use?

On a multi-site system, the drop below threshold will just tell the radio to go check other sites determine if there's a better site to monitor....

If there's only one site, there's never going to be a better option - you only have one site.

I remember this from a while back, however I remember having to create a new site with no frequencies.

I too though really didn't understand the point of it if you only have 1 site enabled.

RWIER -

There most certainly IS a Duplicate button on EZScan for the PSR 800. 3rd Button Top Right on Trunked Radio Systems tab!

WS1080 Tricking Multi Site Threshold setting

To enable the grayed out controls you can just make a "new" dummy site. for the same SYSTEM you're scanning. Just lock out all the controls on the dummy site. A single site uses default controls I guess. The reason* for it was so you can change the multi-site threshold ratings instead of having 75-95 default. Some people like to have it as 15-99 or whatever. That trick was found by someone else who had the PSR800s EZScan. I just remembered reading it.

For me, knowing why is unnecessary. However, if I was to "imagine", or guess as to a reason why it works (using logic without any radio knowledge), I would offer the following (Not technical facts as much as belief):

The default settings of 75 and 95 operate on multiple sites by ignoring sites that don't pass the low 75 setting. With a single site this could result in times when that single site falls below the threshold and is ignored. Lowering the setting forces the scanner to process a signal it normally would ignore.

Now I know this concept is not in line with the conventional wisdom and is not based upon any radio (technical) experience. However, when I tested these settings, I had the 800s set up for various LED colored flashes. At about low 30 or low 25, I noticed a marked increase in colored flashes. At low 15, my scanners lit up like a Christmas tree. It was mind boggling.

Read my post over slowly, or maybe someone will explain it to you.

 

[rwier]

Actually, I posted information on the method and purpose of creating Duplicate TRSs (Each to be a single site system) three and a half years ago.

#12 in that thread.

I would be surprised if one can find a post, previous to that one, recommending that exact procedure.

 

[TAbirdman]

Thanks for the replies guys!

I'm not sure if I entirely understand this post, but would it be possible to just set the thresholds for all sites to 99% and as long as you're not getting perfect decode on one site, wouldn't it automatically continue to search all sites? Or would it not even bother to scan the site because the threshold would be so high that it would continue to search?

WS1080 Tricking multi-site Threshold settings

Here's what the WS1080 manual says about Multi-site trunking threshold settings

"On trunked systems with multiple transmitter sites, your scanner will search for the best site using the settings in this area.

The Data Decode Threshold settings are used to control the selection of the best site.
When a system is first enabled, the scanner will scan through the sites from the first one listed** looking for a control signal. When one is found, the scanner will sample the data stream and calculate a decode rate based on expected data transmission rates. If the scanner finds a site that meets the **high threshold value, it will use that site until the decode rate drops below the low threshold value. At that point, the scanner will attempt to find another site using the same process"

The purpose of this post is.... Some people have only ONE site for a system just to keep any interference away. They like to be able to play with the settings instead of having them greyed out, using only the default settings. Enabling another SITE even if it's a fake one makes those controls come on.

Will lowering the numbers HOLD the site better when traveling? I hadn't thought of that since the scanner looks for a site meeting the HIGH Threshold values first. WHAT IF? you lower the standards of the HIGH and Low? I've been doing that tonight to see and have had some interesting success getting my site even without attenuation *for LSM. This is just using a plain rubber duckie too. I've been using 5-65 and 5-70. I'm testing it tomorrow in the car to see if holding the SITE is any better by having a lower "HIGH" threshold. It's just a fun thing to play around with...that's the purpose. At home I usually just use my 700/800 Yagi anyway...that can't be beat.

WS1080: Tricking Multi-site threshold settings

Thanks. All this stems from questions on RRef from new Whistler/RSPro668 and those who have the PSR-800's new to them. They all ask the same thing? are there any "optimal" settings with my multi-site threshold settings? I have tested things in the Chicago area today with 5-65 and 5-70 settings from Starcom21 Tower #149. The LSM is usually brutal here. It was holding the signal very well even without attenuation of the "SITE" itself. One particular dead spot I know of a "Portillo's" parking lot has several Cell Towers nearby. One big one right across the street. I usually have problems there and have to attenuate, often times get zilch. Didn't have to this time using the RS800 mhz antenna and 65-5 seemed to work well, so did 5-70. I have one V-scanner folder set up with 12 open SITES one County after another and a cascading scale of multi-threshold settings, the next one slightly higher requirements from where I start from. A smooth transition is what we want from tower to tower instead of the next tower butting in too early instead of having ALL sites the same settings of 75-95. This is all just good fun and location and antennas matter greatly. BUT like posters said in another thread, instead of all these little games trying to cope with LSM and with all the money I spent on scanners over the years I'd love to see a great quality scanner capable of stopping LSM like those Professional Motorola radios. If some company made a scanner even close to that? I'd buy it $1000-1500$ whatever and it would have to be upgradeable easily with new improvements that would show up down the road. Of course there's a limit to normal user's budget. I enjoy seeing those videos on Youtube, loud and clear, perfect reception. It can be done,

This is not on the new TRX-1 manual but should be. It's only partially explained in the help menu in the EZScan software. But definitely the part about "if it meets the high threshold level, it chooses that site". Because I had a site within 300 yards of me and a site about 5-10 miles away and it chose the site further away the 1st time I started the scanner. So apparently it met the high threshold even though my 300 yard powerhouse neighbor would've realllllllllly met the high threshold.....probably 100%. Great post and thread though. Took a while to find it
