Grecom

[KF7BR]

Just a question for a Grecom guru. I am a current owner of a Trunktracker IV and grecom PSR 500 and PSR 600. All data bases for the Wyoming Wyolink system were down loaded from RR for each radio. I am in receiving range of these three systems in southeast Wyoming. I downloaded Torrington, Virgin Hill and North Albin. The trunk tracker hears all three sights, no problem. But the grecom's only hear Torrington, which I am the closest to. I have worked hours as to the programming and reprogramming to no avail. Currently they are set as follows. Scan list 1 is only talk groups for Torrington. I hear everything. Scan list 2 is Torrington as a wild card. I hear everything that comes through the Torrington site as a wildcard. Scan list 3 is Virgin Hill with a wild card talk group. It has excellent s-meter readings but is totally silent. The bearcat hears things on Virgin that is not heard on the grecom. Scan list 4 is North Albin same as list 3 but silent. So any ideas?? I can take my PSR500 to work. 30 miles west of Torrington, closer to the Virgin Hill site and it comes alive about ten miles from Torringotn. I have checked just about everything I can think of. Ideas?? Contact me direct dlr@communicomm.com

Thanks
Don

What software are you using for the GRE units? I use WIN500 which works quite well and you can use it for 30 days after downloading it from here for free: Win500: PSR-500, PSR-600, PRO-106, PRO-197, PSR-310, PSR-410 Scanner Software for Data Management, Monitoring, and Control.

If you could attach the file you use for programming the 500 and 600 in WIN500 format in a response I, and others could look it over and see where your problem might be. I think you may have to change the .p500 suffix to a .txt for the attachment to work on these forums but that is no problem as we can change it back to .p500 to read it.

If you can't or don't want to use WIN500 and you are using either ARC500 or PSREDIT then you can do the same thing anyway - there are others on here who use those programs and can help you in the same way as I described above.

I suspect you have all the talkgroups and wildcards in the same default scanlist (#1) and you are trying to select the number of the scanlist to be the number of the trunked system you have programmed. You would be better off using the Win 500 software or PSREdit software to program your GRE radios. The "Trunktracker IV" uses a separate system/groups/channels for each system you program so turning on and off the system you want to hear would be fine. This FAQ may be of use to you.

My guess is this may be an issue with the Grecom radios and their VHF sensitivity (slightly lower than some scanners). Your comment that you can receive activity closer to the towers makes me belive this is the case. I would verify the attenuation is not turned on as well. The Grecom scanners may require a better antenna for VHF systems?

i respectfully disagree with your statement regarding gre's sensitivity. numerous discussion's can be found regarding this issue. that, combined with my own observation's make a case for gre's having good sensitivity. the problem is "selectivity" <the receiver's ability to hear weak signal's over strong signal's>.
this can also be a problem.

Att may help.

also:

Switch Multi Site Mode to STAT then select "Check all CC's in every scan pass".

I second on the VHF sensitivity. I used my Pro 197 in Wyoming last year and it performed flawlessly on the Wyolink.

Grecom PSR 600

Thanks everyone for the input. I have however discovered the problem. I do have an RF spurious emission problem in my area on the programmed conventional channels I programmed. Over the weeks I tended to set the squelch threshold higher and higher to take care of that problem. Then I forgot about that. Yesterday I moved the conventional channels back to my analog scanner, turned the squelch on the Grecom back to the minimum and guess what?? I hear all of the sites. So no programming problem, the Grecom works fine. And for the responses. All of the attenuation features are off and the individual wildcards on each system are on different scan lists. I guess blame the idiot at my computer keyboard. Thanks for all of your help.
