Re: [IRCA] Using LW beacons to predict MW TP DX
Alex Wiecek VE3GOP has his Worldwide Search Utility (WWSU) with a full NDB
database and a mapping and distance function when you enter your home
location coordinates. It's a small shareware fee to unlock the full program.
I couldn't do without it for my own NDB DXing.

I don't check NDBs to see how MW conditions are, though. I do check for
Pacific beacons most every morning and find that the LF signals peak prior
to the MW signals. That's good for me as when the NDBs fade out then I
switch to MW and check that.

Subject: [IRCA] Using LW beacons to predict MW TP DX
Does anyone else do this? My favorite check is 368 kHz. If ZP in Sandspit,
BC, 100 mi S of the Alaska panhandle, is coming in, audio or at least
carriers from Japan will be heard in MN. If SX Cranbrook, BC is there
instead, Japan probably weak carriers at best, DUs are possible. If only VX
from SK is in, there will be no mainland Asia carriers, but weak DU carriers
possible. If even no VX in on 368, DU carriers very unlikely in MN, & TPs
will probably be poor even on WC.
Of course, if you're not near MN, you might need to use different LW beacons
to predict MW TPs. I suppose one could use a string & a globe to determine
what beacons are along the signal path to Asia or DU. Is there an online
site that would help determine that, for those DXers that don't have a
globe? 73, George S., MN
