Heard some brief traffic this afternoon on Site 84 from my listening post here in Fremont. TG3555 and later a female dispatcher with a veh reg return. Didn't catch the TG of the latter. I'll be listening to sites 67,68 and 84 more often now.

Are you receiving the signal from Site 85, and where are you receiving it from?

Site 85 was discovered from the neighbor list advertised from site 68. I cannot hear Site 85 here in Fremont.

I poked around a bit over the weekend, from Brentwood.

Mt Diablo is strong, of course. Site 71 seems to be the next strongest. I can hear 77 and 79, but they're weak.

79 claims to have a neighbour of site 66, on 173.1500, which is not listed in the DB. I don't hear it.

From Fremont I am barely able to hear Site 80 (170.100), but was able to get the neighbor list and found two more sites which I cannot hear:
Site 82....169.8875
Site 85....172.0125

I'd like to (very loosely) propose Site 71 being on or near Mt. Vaca if you have it in Brentwood. Site 71 is a neighbor to Site 78 which is Round Mtn in Tehama, and to Cohasset in Butte. That would be logical for roaming users coming up the valley on I5.

Seems plausible. 77 (Sutter Buttes) is another neighbour of 71.

Confirmed and submitting Site 74 (169.550) is South Fork Mtn in Shasta County.

Confirmed and submitting new Site 81 (169.9125), Horse Mtn in Humboldt County.
Neighbors are 74 (South Fork Mtn, Shasta), 75 (Cohasset, Butte), 76 (unknown) and 78 (Round Mtn, Tehama).

<start rambling> Site 76 (171.325) is an interesting hole in this equation now, being a neighbor to both Tehama, Butte and Humboldt County, the easy answer is I want to say it's down the 101 corridor a bit towards Ukiah and would allow roaming east over Hwy20 into the valley and north to Eureka. :unsure: But if the system designer is worth their salt, the 70's seem to be all northern Sac Valley and the 80's look to be bay area and likely the 101 corridor north. If it's valley though, everything seems to be covered by the big players (vaca, sutter, cohasset, round and southfork). So my bets are on Ukiah. (20 minutes later) Just had a friend in Ukiah tune up 171.325 and it's full quieting. :sneaky: So likely Mt. San Hedrin for 76. <end rambling>
