Longwave Loggings / Re: Early NDBs heard in northern CA

do you mean KZ?
if so I just barely got it, ten minutes of trying to copy with my 150 hz cw filter.

Actually was referring to the Kansas beacon 395  ULS.

Keep the logs coming.
Have heard a number of the British Columbia NDBs here but have never logged anything in WA, OR, CA.
So, keep the logs coming, gives me some beacons to seek.

That YPL  Pickle Lake  ON is a real powerhouse.
Said to be running a KW and heard as far away as Europe.
Nice catch on the KS beacon, that one is elusive here.

If you hear the beacon MF again, the ID interval for MF Medford is reported to be 7 1/2 secs and almost 6 secs for MF Mansfield...
good method to distinguish between them.

Also, somewhat recently obtained a MFJ 722B CW/SSB filter for the shack here.  It really helps pull the weak signals out of the noise
as well as cut down the mixing and whistles of nearby signals.

In my station I have a printout of all the beacons listed copied in California. and so far all I have copied are on it. I will be quite excited if I copy one that is not.

If you have the space available, lengthening your antenna may help.
NDB DX is picking up as Autumn approaches.

I originally thought the MF was 373 in Medford, but I am confident in my receivers frequency accuracy. I have not however heard MF again, from either location. and certainly not in the daytime.  Even MEF in Medford is usually weak here.  I would love to have heard MF in Ohio, and maybe I did, but I wont assume until I log it again. 

The transformer I use is a small 1.25 inch moly toroid, with 100 turns of 24 ga. magnet wire and 5 turns of 18 ga. insulated wire. The 5 turn winding is secondary and feeds my 50 ohm input directly. the 100 turn winding is fed by a 25 foot tall, 35 foot long inverted L, against ground.

You may be aware of this but FWIW, U.S. beacons are modulated at 1020 cycles.  Therefore a signal will be heard offset 1020 cycles either side of the carrier frequency.  In other words, a beacon transmitting on a frequency of 373 will be heard at 372 and 374.  Canadians mostly use 400 cycle modulation.  Some beacons, especially Canadians, may only transmit one sideband, usually upper.
In actual practice this can be interesting, for example, if your receiver has narrow enough bandwidth, you may be able to receive a U.S. beacon and a Canadian beacon both assigned and transmitting on the same frequency.  Tuning upwards you will first hear the U.S. lower sideband then the Canadian then the U.S. upper sideband.

This does not necessarily mean that you didn't hear the Ohio beacon.  You may have heard it because MF Mansfield has been reported heard in California.

Otherwise, thanks for the transformer info.   :)

ElectriCat,

Got curious about the 2 NDBs associated with Medford, Oregon. 
The airport is known as Rogue Valley International Medford. 
As per its name, it is located in a valley.  Looks like lots of high rapidly rising terrain all around the airport.
Could be a bit of a challenge in crummy WX.  The NDB 356 MEF looks like it is on or just north of the field.
NDB 373 MF is a LOM for ILS/LOC RWY 14.  It is located about 4 nm from RWY 14 threshold.  There is also
a VORTAC located a short distance north of MF.  Lots of navaids for this airport, perhaps because of its
location.  This information was the result of a quick internet search and may not be current.
Lots of navaids are being taken out of service.

btw,  any info on that transformer would be appreciated

A little surprised to hear ohio nearly 2400 miles from me. but I certainly got a positive ID.
My inverted L feeds the 50 ohm input of my receiver through a 20,000 ohm to 50 ohm isolation transformer. it really brings a lot more signal in than the loop in my shack

Could be the Ohio beacon, don't hear it very often here at my Michigan QTH but it reportedly is still on the air.
However, there is also an NDB MF at Medford, Oregon on 373kc, maybe that is what you heard.

Anyway, what are the details on that transformer ?  Where did you get it or was it something you built ?

...teach kids how to solder any more?

Way back when, when I was manager of a tech department, we had a written test to filter out the chaff applicants. And boy was there a lot of chaff. Basic questions on how diodes and opamps work. Both 2 year tech and 4 year EEs often had troubles with these kinds of questions. Some schools worse than others, I will not name any, to protect the guilty.

I used to joke that I wanted to add another test, throw a (preferably hot) soldering iron at the applicant, and see which end they grab. HR would not allow this. Eventually we got bought by a major large corporation and their HR department made us completely stop giving tests. I guess they were unfair to the chaff.


HR departments prefer to hire incompetent individuals...   they don't have to pay them as much as qualified individuals.

Oh well, another one bites the dust.
That was a real powerhouse, could almost always count on receiving it here at night.
Thanks for the replies.

Good on ya mate !  Bloody nice.

Is 216  CLB  Wilmington  NC  still on the air ?
Haven't heard it lately.
198  DIW  Dixon  NC had a nice signal in here this morning but CLB nowhere to be heard.

BC and NU, looks like the DX is picking up.  :)
Heard that Cadillac MI beacon this morning... been doing that MET thing for quite some time.
