You need an EF Johnson Multinet-Capable radio- and a system key. Or you can download this program: http://name=Downloads&d_op=getit&lid=74 You would also need to add a data-slicer to your scanner. Seattle Frequencies: 1. 866.03750 2. 866.56250 3. 867.06250 4. 867.13750 5. 868.13750 -Mike |

It takes audio from the discriminator. THat is, it is the unfiltered signal before it is turned into a physical sound. That way the data remains intact. This page shows you how to mod. the Pro-97: http://www.naturalgfx.com/pro97_discriminator.htm -Mike |

Thanks for that Mike, that's very fascinating. What would happen if you just punched in those 5 freqs and scanned them conventionally? I realize you might not follow conversations properly everytime, but I imagine there's not that much traffic? I suppose I should try it, but has anybody had any luck with that? |

I don't quite understand the layout of WaDot's LTR multi-net, but here is what I usually do to monitor a local area. I program for instance the 'home channel" of 852.6625 in which I might hear one side of the initial conversation but not necessarialy both sides. I then have to switch to the "status channel" for that area say, 854.1625. I usually hear both sides on that but not always. If I try to monitor the home channel, it sounds like a constant carrier which is annoying to constantly listen. Unless I've got it backwards, refering to 'home' and 'status" this is what I do. If you're in King Co. the 151 mhz link should work, but maybe it's just for the east side. |

I may have been sleeping again -- ( I was in the LA Dodger dug-out with everyone else that was asleep ) but --- doesn't the PRO-97 -- receive LTR systems ??? Isn't the PRO-97 one of the very few that can decode LTR signals ??? If so --- check your owners manual on how to program it to work. |

I've got an unprogrammed EF Johnson 85XX portable, but it will be outdated as soon as rebanding takes place. The replacement radio is the Ascend Portable. I does P25 IMBE, Smartnet/Smartzone and LTR Multinet. It would be the perfect radio for SPD officers who need coordination with WSDOT workers. I'd guess WSP would need it more than SPD though:

That's what I like about EFJ. Radios that are worth more as bulk scrap -- than as two-way radios. Just like my old EFJ 949 UHF repeater. JUNK. as for the idea of State Patrol/Police needing to talk to the highway crews --- it's a very very very low need -- if any. Good idea. -- Just not on the "this to do" list by state officials. |

Yeah, how often is the 'patch' up on Snoqulamie used by the WSP to communicate or is it just a WsDot reciever on the WSP channel line-up? |

Hum,what do you mean? When WSP transmits from Snoqualmie Pass they are talking to the repeater on Stampede Pass (just east of Snoqualmie). I'm pretty sure WSDOT has a transmitter on Dodge Ridge co-located with the 800mhz KC TRS system. I've always wondered why WSP didn't put a transmitter there but I guess they just don't need it. |

Around here (Goldendale) I think the WSP cars have DOT radios. |

WSP is at Stampede and Rattlesnake for I-90 if memory serves me correctly. The Dodge Ridge site isn't a really good site for microwave. Stampede really is a good site for microwave. |

How about 151.025, that transmitter, the one that supposedly used as a cross patch between WSP units on VHF and the rest of DOT crews on 800 |
