GRECOM PSR-800 scanner on WyoLink
GRECOM PSR-800 scanner on WyoLink
Howdy all:
Had a gent stop by with a PSR-800 the other day; got a chance to play with it on WyoLink for a bit. Programmed in the WyoLink trunking system wth all the VHF & 800 sites, and discovered something interesting. Seems that the 800 - unlike the 500 & 600 - does not have a STATionary trunking scanning mode: it is “stuck” in ROAM mode. If you don’t know what this means, check out the forum on GRE scanners and look through the postings on the PSR-800.
WyoLink has 3 areas that have overlapping coverage on both VHF & 800: Cheyenne, Casper & Gillette. Turns out that the Roam mode in the PSR-800 locks the scanner to the first strong site that meets the decode signal strength settings, and there the scanner stays until it moves away from that site and has to look for another site. During the tryout, the unit locked to the Cheyenne 800 site and would not scan to any of the VHF sites in the area. This is a problem because 90-95% of the time a talkgroup isn’t routinely going across to the other band. Sticking on 1 band will miss all the activity on the other band.
After a bit of head scratching, the workaround solution turned out to be very simple. What you want to do is to set up 2 trunking systems named WyoLink VHF and WyoLink 800. Then you program in all of the VHF sites (currently 50) to the WyoLink VHF system and all of the 800 sites (currently 4) to the WyoLink 800 system. Set up a wildcard for talkgroup and a wildcard for radio id in each system while you’re at it. The bad news is that you’re going to have to load all of the WyoLink talkgroup information into both system entries, probably by hand since there doesn’t seem to be any good way to cut-n-paste. (There may be a quick way to do the duplication, but I did not come across one in the short time I had to play with the unit.)
This will get the PSR-800 working fairly well on WyoLink, but as seen on the GRECOM forum discussions, the lack of a STAT mode is a serious drawback & handicap. In VHF only areas, the unit locks to 1 tower and will not look at other towers in the area that it can hear, thus missing out on traffic on those other towers that is not being carried on the tower that the radio happens to be locked on.
Bottom line: unless & until GRE updates the PSR-800 with user selectable STAT/ROAM, I’d recommend using another scanner than the PSR-800. Too bad, too - the 800 seems otherwise to be a nice slick little unit.
