Amateur Radio / Santa Nets are back. Tis the season.

They're back! The Santa Nets on 3916Khz,   https://www.cqsanta.com/  It's neat listening to them coordinate those.

I'll welcome the cold snap, if it will clear out the T-storms that keep trashing the LF, MW, and lower HF, bands.

You can do the best of both worlds with AM Part #15, like I am. I'm doing the just under 100mW to a 9ft antenna. How far that gets you depends upon what's around you and soil conductivity. In the Summer, I don't even reach 1 mile in some directions. Winter, I've heard my signal up to 3 miles, but in the middle of a quite, noise free, parking lot, and with the engine off. Any bit of noise would obliterate that. Oh... And that's middle of the day. At night, hammered by night time propagation. That's where the other method comes into play, AM Carrier-Current Coupling. Some are now calling that PLC = Power Line Coupling. I stay away from FM, since the political climate for that just sucks. So, how far does that go? Thus far, this is the worst location for it. Before hand, I did Carrier-Current in a town square, and later, in a suburb. 1.5W carrier was heard in some areas as far as 3 miles, and this is from the street measured. Just how far that went into people's houses and apartment complexes is anyone's guess. Where I am currently, in one direction, there's a brick-wall utility transformer that stops my Carrier-Current station in one direction. So, it doesn't matter if I do 100mW, or 10W. The other direction is a little better at about a mile. I also use a much lower FREQ for Carrier-Current, (Below 1MHz.), and that carries further on the long power lines. What puts people off of Carrier-Current Coupling is coupling to the power lines. I Neutral inject, although myself and another station op are trying to make a Layman's Plug & Play AM Carrier-Current Coupling Transmitter. And, we have a model where this has been done for decades. Wireless FM Intercoms that you make use from your work shop, basement, den, kitchen, garage, etc., that uses the house wiring to carry signal around the house on most NBFM, but some AM ones were made, and FREQ's from 140kHz to 180kHz. Then, there's the posting and links from Boomer's page,   https://www.hfunderground.com/board/index.php/topic,72355.0.html   Lots of good info there! He should have the 1959 article of the AM broadcast band Carrier-Current Baby Monitor. So, How cheap can you do all this? That all depends upon how resourceful you are. So, like to have you on AM. We look for all the permissible license-free loop-holes we can get. Good luck!!!!! OH!!! Here's another DIY link for you from MRAM1500 with his home brew Part #15 antenna for his AM station,  http://mram.us/AntennaStory.html  I may follow his lead myself, if something were to happen to the present copper 9ft antenna that I am broadcasting with.

Since I don't get home from work now, until stupid o'clock, (Like around 7:00UTC), I miss a lot of Amateur Radio activity, or do I? More and more, I hear the FREQ of 3799Khz being used as the LSB 75M DX Window to Europe. A good test for my Windom, as I can seem to copy 90% of what's trying to shoot over here. So, from about 1AM - 4AM EST on the East Coast, the Europeans are trying to shoot over here. The Big-Guns are the ones with 75M beams up over 100ft and running over 400W, but 100W, dipoled, stations have been heard over here. So, test your RX on that FREQ and find out what you can hear. Most stations report what power and antennas they are using, so even if you never intend to QSO on 3799kHz, it's certainly worth testing your RX capabilities there.

I still miss AES. Always done very well with them. And, for A/V gear, I still miss WDS, (Wisconsin Discount Stereo.) Am I showing my age by saying that?

Radio Shack! You've got questions? So do we!

Well, here's my go-to site when propagation is starting to open up,     http://www.dxmaps.com/spots/mapg.php?Lan=E&Frec=50&ML=M&Map=W2LN&HF=N&DXC=ING2&GL=S

I'm going to try and get a 2M SSB beam up for the Winter ARRL VHF Sweepstakes:

January VHF Sweepstakes: The third or fourth weekend in January. See the current rules for this year's exact date.  1900 UTC Saturday through 0359 UTC Monday.

I heard a weak station in there as well on 12M yesterday. Maybe I heard you doing a band-scan. Thought that it might be folks looking to get away from contestants.

Up where I am, May through early August has been prime 6M season Sporadic E. Then, there's the very short Winter "E" season right around Christmas to about the 1st, or 2nd, week in January. A bit longer for 10M, 12M, and especially 11M. I've had a 10M QSO via "E" a couple of days ago, so maybe we just might have a decent 6M "E" Winter season, for once. That would be nice. 

Thus far, the best GND conductors that I've used are trashed coax cable outer braids. You've got contaminated RG-8, or some other type of coax, use them as GND conductors. Might surprise you upon how well that can work, especially 5MHz and way under. Cheaper than 6" wide copper strip conductors.

Oh yeah??? Here's a real test. Can you talk down to the PA border regularly? On Alma and North Hills in Allegany Co., a decent mobile station could easily hear the dudes up in Buffalo / Niagara Falls. Then again, most of them were running stupid power, so they didn't hear me at the time.
