L-G,

Did you get that stuff on the Tecsun S-2000 ?

All received via the Yaesu FT-2000D base station, Tecsun drags in too much crud and hetrodyne on low bands.

Got the Satellit 750 equivalent here.  It does a fair job on LW with a good antenna but is likely to pull in  AM broadcast band "images" and other "crud" plus it lacks narrow enough filtering and the fine tuning required for really serious LW DX.  Otherwise a nice radio for casual SWLing.

What are the details of your 310' antenna ?

Just wire strung through the trees out the back of the house in an upside down "U" configuration, seems to work quite well. 

During the 2016 season I logged JJY Time Signals on both 40KHz and 60KHz in the early hours of the morning here, both transmitters are 50Kw.

A big problem is the spurs, images and carriers generated by "modern devices" of my nearby neighbours from computers, refridgerators and flat screen TV's in addition to the sub carriers and birdies generated by the powerful MW transmitters that make NDBing difficult.

The Tecsun-2000 has very poor rejection and filtering generally so all serious DXing across LW, MW and SW is done on the Yaesu FT-2000D, the Tecsun is totally useless on LW.  :D

L-G,

Same problems here with the RFI/EMI crap.  Most DXing has to be done after midnight and before dawn when the neighborhood electronic junk quiets down somewhat.

The NDBs here in the States use 1020 cycle modulation whereas the Canadians most all use 400 cycle modulation with a long Dash After ID (DAID). 
What do your beacons sound like ?  My chances of ever hearing one are about nil but just curious.

Otherwise, do you couple your long antenna to the FT-2000D direct or do you use some sort of balun or unun such as 9:1 or whatever ?

Wire is direct to rear of FT-2000D via a PL-259 plug, going to see if I can add another 50 feet to it when I get time, wire needs replacing as large Sulphur Crested Cockatoo's often snap it, they are a large bird and vandalistic ones at that.

Plenty of Australian NDB clips can be found on You Tube, try "Australian NDB's" in the search box.

Nearly scored "TUT" on 403KHz in American Samoa at Pago Pago Airport this morning around 1615z, it was a border line 219-319 report at best, didn't claim it as could only get the "U" and one "T" out of the noise but not full call sign sequence, 4,478kms from here.

"CI" Chatham Islands on 322KHz was coming in quite well at the same time which lead me to look for Pacific island beacons further afield.

A lot of the Pacific island NDB's are low powered 25 to 50 watts with just a few running 125 or 200 watts plus in the region so they are a rare catch this way. Modern man made noise plus splash over from Australian high powered NDB's make the going tough, not to mention associated crud from MW broadcast stations running big power.

Many beacons in this region were "retired" during late 2016 due to GPS Navigation being implemented and thus many NDB's no longer required, around 200 went off air in Australia, a few in New Zealand and many in Papua New Guinea were withdrawn so not a lot left.

Frustrating isn't it when you can only get one or two characters of a DX call. 



Some NDBs are being decommissioned here as well.  Lost several locals around here over the past couple of years.  The Canadians seem to be holding on to most of theirs...  usually hear more Canadians than U.S. from my QTH.

You may want to try connecting that wire antenna to the receiver via a 9:1 balun (unun) for a better match.  You can buy one or build your own, plenty of plans on the internet.  Have had good luck here with #43 material for LW and MW.

Otherwise, almost logged  one this morning on 344... it faded in and was able to copy C?Q,  heard it send the ID several times and it faded out and gone.  Probably CGQ Corsicana TX but didn't get a solid ID so it doesn't get logged.

I found on 344KHz CQL Carbondale CO at grid square DM69jk with 100w transmitter.  Maybe it?

Probably not, looks like CQL has been off the air for quite some time.

Just wanted to show a situation similar to your experience with TUT...  a fairly common occurrence when beacon hunting. A signal will suddenly fade in from out of nowhere and you may copy one or two characters of the ID and then it quickly fades out and gone.

Anyway, never coped the middle character but was probably CGQ in Texas.  So, for now, it doesn't get logged.   Good luck with your beacon hunting.  :)
