Default 120 meter opening ?

Last night, 28 Mar. 0350z to signoff at 0400z Radio Voice of
Vietnam, s3r3 between heavy QRMN on NC125 with 156 ft off center feed
antenna in upstate New York. Male and female voices talking
(Vietnamese?) way down in noise until signoff in English. Frequency
slighly down band from 2.400...estimate 2385.
Does this correlate to any published schedule and frequency. If
so was it direct from Hanoi or a relay ?

I'd say you have an image problem with your receiver. What are you using?

2385+455 = 2840...probably not an image.

Image would be 2385+910 = 3295

Hollow state boatanchor National NC-125, recently realined with
HP-8646B sig gen.
2385+455 = 2840...probably not an image. 2385/2 = 1193... call
it 1190...possible 2nd harmonic of domestic US Vietnamese station, but
Google seach on domestics didn't find anything near that, and the
signoff was definately RVoVietnam. QRMN from forced air, gas fired home
heating ignition made listening really tough, but the signal had some
QSB and sounded *really* far off and multibounce. Propagation on the 90
meter band was among the best I've ever heard last night, so I went down
to 120 meters where I dont usually hear anything. I was unable to Google
any time/freq listings for RVoVietnam...just propaganda about
programming. If I'd been using the Sat800 I'd at least know the exact
freq, but I was just band cruising with the bedside NC-125.

Maybe a harmonic from 1089 KHz or an image in your receiver from it?

From upstate New York with a 156' antenna, you don't copy anything in the
marine band from 2182 KHz on up? They are fairly active along the entire
Eastern seaboard from the Canadian Maritimes to San Juan, Puerto Rico. I've
worked a SAR case 1600 miles out on the Atlantic on half the antenna you
have.

Try:

Coast Transmit Ship Transmit

2514 2118 (Canada)

2582 2206 (Canada) 2049 (Bermuda)

And Simplex:

2182, 2670 (US Coast Guard)

2598, 2749 (Canadian Coast Guard)

I listen a lot to the 2 mhz marine traffic as I'm something of a
USCG fan as a result of being the originating station of a mayday on
2182 in Cheasapeake Bay in 1977. Coast Gaurd Radio Annapolis and a
crash boat crew out of Easton MD busted butt to help me get medical evac
of a man overboard. Marine band traffic can be really interesting.


Good to hear that William. 2182 KHz is still used a lot, in spite of the
fact that the U.S. has never declared a Sea Area A-2 that would mandate it's
usage. The majority of coastal-Atlantic Mayday traffic is from fishing
vessels in New England waters. The stations listed below either make regular
Marine Safety Broadcasts or come up on 2182 KHz for SAR cases, or both:

UNITED STATES COAST GUARD
USCG Group Portland ME
USCG Group Southwest Harbor ME
USCG Group Woods Hole MA
USCG Group Moriches NY
USCG Group Long Island NY
USCG Activities New York NY
USCG Group Atlantic City NJ

USCG Group Eastern Shore VA
USCG Group Hampton Roads VA
USCG Aux Oceana Radio Va Beach VA
USCG CAMSLANT NMN / F / G / A
USCG Group Cape Hatteras NC
USCG Group Ft Macon NC
USCG Group Charleston SC
USCG Group Mayport FL
USCG Group St Petersburg FL
USCG Group Mobile AL
USCG Group New Orleans LA
USCG Group Galveston TX
USCG Group San Juan PR

Bermuda Harbor Radio ZBM

CANADIAN COAST GUARD
Labrador Coast Guard Radio

My guess is that somehow the receiver was picking up the relay
out of Sackville... They still using 6175?

A harmonic from 1089...? How would it propagate? At least so as
to be audible where he heard it, frequency wise.


Just grasping at straws. My best shot is the transmitter had a 2X
or 3X spur.

The web page lists 6165 on VOV4.

They broadcast on a number of medium wave and short wave
frequencies. If this is at the same transmitter site maybe they
have a mixing problem.


Yes, I understand that... but the question would still be then how
would it propagate if the mixing product was from a transmitter site
in Vietnam? At that time there is no darkness path from Vietnam to
his receiving site to facilitate reception on that frequency.


Well that settles it then.

I'm still betting on Sackville... and a receiver fault.


I didn't know that they relayed VOV but if they do then it would be a
much more reasonable explanation.
