Wild CA conditions the other night

[DPD1]

Was doing some listening from 2800' along the SoCal coast from late afternoon to late evening one night last week... There must have been some real temperature fluctuations or something, because the conditions were crazy... One minute stuff from one direction that I've never heard before period, would be coming in perfect. Then those would disappear, and I would get the same conditions with other signals, but from a different direction. Conditions seem to get the most crazy when the temps change the most radically between day and night.

Signals over water can be very interesting in general... Sometimes you can hear a ship full strength, and then hear it fade within minutes. I've always wondered how much of it is conditions, and how much is due to traveling past the horizon.

Now I'm just curious if you're talking about the VHF-high maritime channels when you refer to hearing the ships.

VHF and also UHF. Kind of fun when you use a directional antenna as well, so you can get an idea on where the ship is.

I've listened to the VHF maritime band, but what freq ranges are you monitoring for UHF maritime? Is it the milair band? Or trunked systems? I'm not familiar with UHF maritime.

I only get skip on the 42.00 CHP channels from the south. I can hear the southern accents.
Lowband is the best for skip. Never got it on VHF or 800 MHZ.

Hello All,

Here is a post that I made to my local San Diego Scan Yahoo group on the same subject yesterday:

Hello All,

Throughout this past weekend I've been hearing a lot of east coast
emt/fire traffic on my Pro-95; in the worst room in the house, the
traffic is booming.

While monitoring SoCal fire traffic, the scanner stops on 154.16 MHz
[what I thought was OES #1] and I hear times that are three hours
ahead of us.

"This is Warren Township Rescue, go ahead with your traffic...", or
"the MacDougal family is requesting a tanker and an engine on State
Route 668...".

All transmissions are accompanied with a Southern accent, by the way.

How does one pinpoint the transmissions with some degree of accuracy?

Many thanks!

Alain
