Did someone post this site before?    http://en.blitzortung.org/live_dynamic_maps2.php?map=30      Scroll west to North America, then use the +/- to zoom in. About a 7se - 20sec delay on this map seeing what you have LIVE. Tis the season.... Too damn soon.

10/11 meters / Re: People who live in glass houses...
« on: March 23, 2020, 1901 UTC »
Back in the 80's, there was a very close analpore 1/2 mile down the hill from me whom pissed-off two states, four counties, and every town he'd visit. He even ran fake call signs on the 10M band, and back then you could get away with it, for a while. However, even when he ran so-called barefoot power, he still spurred a harmonic at X5 the fundamental FREQ. i.e., CB CH19 = 27.185MHz X 5 = 135.930MHz. I had a scanner that did AM aircraft band, so when that dude keyed up on CB CH19, I knew it right away over the scanner. A bit more difficult on CH38 LSB, but you could still do that to tell that someone very close is keying up there. 27.385MHz X 5 = 136.930MHz. When the scanner stops and unsquelches on SSB in AM mode, then you'll know he's there. And, when these dudes ran power with CB's, they almost always kick spurs more into the aircraft VHF band. Hey, no doubt that he covertly monitors YOU, so here's a way to keep monitoring HIM. Certainly nothing illegal about monitoring that way. Oh BTW... Don't have a scanner that does AM aircraft band? Then try an analog tuning FM receiver at the very end of the dial, i.e. 27.185MHz X 4 = 108.740MHz. Many of the older analog receivers can go there. If anything, this is a nice experiment to show and learn how harmonics work.

While you're on this Part 15 kick, here's another site,   http://boomerthedog.net/radio.html

Yeah... This month we've got new HAM's and Generals upgrades. Ironically, not more repeater activity, but I did talk to one of the new HAM's on our area 10M USB chit-chat FREQ.

And, more activity on 17M (18MHz), centered around 18.140MHz, during the daytime.

Really??? Your IC-718 isn't open to 5MHz on TX? That OCD and a tuner would do it. I too use a home brew OCD, with a 1990's 4:1 W2DU current balun. The auto tuners on both the semi-older Kenwoods won't do 60M, (They can't seem to decide to use the 40M, or 75M, settings.), but my MFJ-941D manual tuner goes there very nicely. And, with 60M, you are on par with everyone else, USB, or CW and FT8, at 100W ERP MAX. Well, except for the military, they no doubt run stupid power. And, you'll hear them from time to time, even doing military to amateur radio call-in tests. And, during the day, 60M is a great regional NVIS antenna set-up band. At night, coast to coast is very possible, even to the UK. And, with the band channelized to 5 FREQ's, you know that some douche that's only 2KHz away from you won't be keying up a kW. I enjoy it, and the three rigs that are opened up to TX there do it nicely. I put each of the 5 FREQ's into their own memory channel and alphanumerics, so that there's no mistake in FREQ / channel tune-in. Passing thoughts... 73!!!!!!!

Huh? / Charleston Hamfest CANCELLED this SAT March 14TH!!!!
« on: March 12, 2020, 2046 UTC »
FROM: Mike, NU8LL,     FYI:

I just received formal notice from one of the hamfest committee members that the Charleston hamfest has been cancelled for this year.

I am sorry to hear this.  I was still planning to attend.  But I stand behind their decision, as they do it in the best interests of everyone.

Please feel free to pass this information on, as it is a late announcement.

73,
Mike

GOOD!!!! Now you can also work those dudes in the afternoon on 60M, and later Sporadic "E" 10M around May. Speaking of which, caught a dude on 28.415MHz USB whom just upgraded to General Class and threw together a 102" whip and home brew GND radials to get his Anytone rig on 10M. But, wait until you try a 102" whip on other bands with just RX. Then, TX with a tuner down as low as 20M. Even MW isn't half-bad to DX with such an antenna. Be lookin' for ya on 10M! Even the OCD does decent on an "E" opening.

Huh??? Left for work just before 9:30PM last night, and after I'd gotten past 1/2, I'd figured that this Cuban station be walking over my AM1620, but something else was in there. I could clearly hear Survivor - America Heartbeat, then The Police - Spirits In The Material World, then Madonna - (A slowly one of hers, but couldn't remember the title.), then Genesis - I Missed Again, then The Fixx - Saved By Zero. No ID... On the way back, it almost sounded like a weak station with dead-air, but the other DX stations were heard in the background on 1620kHz. So, any ideas whom that is? decent MOD, but not AM wide banded.

Amateur Radio / Re: Thoughts on HF verticals
« on: March 04, 2020, 1952 UTC »
I've always done great with upper HF VERT antennas, from 20M on up, but for 40M and below, in 2007 I tried out Shunt Feeding my 50ft tower that I had at the time. Simple set-up, a Yaesu FT-857D transceiver, MFJ-941D manual tuner, and a simple Shunt Feed to the tower using only four 100ft GND Radials. How did it work??? So-so on 100W TX on 160M, 75M, 60M, and 40M. I already had a 40M dipole, and no way did the Tower Shunt Feed beat that, but it was less noisy on RX. TX tune-up on the preceding lower bands seemed easy, but when I broke-in to several nets, several times I'd get back, "You are not strong, but we could hear you above the noise level." I actually had gotten into a 160M net in PA where folks said the same, "Not strong, but can hear you." 160M is the band where they seem kind of snobby, if you aren't at least an Arm Chair S+20/9 copy, they don't want anything to do with you. RX was a totally different story. Just about everyone was coming in at least S+20/9, and very, very low noise floor. But, medium wave was the big surprise! In the middle of the day, NYC's big 3, (660kHz, 770kHz, and 880kHz.), were all coming in at an S9, and NYC was 300 miles east of my QTH at the time. I was hearing 1kW stations from+100 miles away! So, on MW, that Shunt Fed Tower was a MW DX king. I didn't keep it for long, since I'd gotten rid of the tower, the FT-857D, and that 1,800ft ASL property, to get the hell out of Western New York. So, if I every do a Shunt Fed Tower as a VERT again, next time I'll invest into at least 20 100ft GND Radials. How do you do it? Just type in the search engine "Shunt Feeding A Tower", and several neat sites come up with various methods to do so. I still want to run a VERT insulated wire up the trunk of the tallest tree where I am now and see what that does.

So, you can hear in DRM, "I am Maati! And this is my wadio!"? I miss Voice Of Laryngitis rippin' on that.

10/11 meters / Re: 11 meter private comms?
« on: March 02, 2020, 1828 UTC »
If you want to protect computers, iPads,loaded USB thumb drives, hard drives, and radios, from EMP's, store them in a trashed microwave oven. Yep, everyone out there has a Faraday Cage. When the megnetron blows up, just cut the line cord, take out the trays, and thar' ya iz, a free Faraday Cage to store static and pulse sensitive electronics. Back to digital packet bursts on MURS, in rural areas gas, electric, H2O, and other utilities, use that band a lot, and data transmissions are legal there. And yes, if you listen to some of those bursts while mobile, some of those carry for over +10 miles. On voice just about every Walmart uses CH's 4 and 5. One Walmart that I know is located on a hill, I've heard their employees from +5 miles away just using HT's. BTW, in WNY MURS CH1 was very popular from Buffalo, and some very early mornings, they could be heard down by the Pennsyl-tucky border via Tropo.(Not Pennsylvania. If you've been to Mckeen, Warren, Potter, and Tioga, counties, then you'll know what I mean. Hi-hi...) But, VHF MURS goes where 2M HAM does, and DX up by Lake Erie is inevitable. (Neat, but bare that in mind.) Also, in the land of P.O.O. (Province Of Ontario in Canada.), you will hear EMS and business tone out from there. I was able to hear London, ON ambulance tone out on MURS CH3 from about 160 miles away. Just some perk, and jerks, to consider.

Boomer told me about this MW page,     http://radio-timetraveller.blogspot.com/2010/08/mediumwave-oddities-transmitter-power.html
It's kind of like the AM side of the late Bruce Elving's FM Atlas. Neat read, and free.

10/11 meters / Re: 10M FM repeater activity
« on: February 21, 2020, 1951 UTC »
Oh yeah!!!! Over 20 years ago Hamburg, Germany had a 10M FM repeater on 29.690-MHz that boomed in with F2 PROP. Je ne c'est pas on the PL tone. Is that still active. About that time, I remember reading about 27MHz Russian repeaters. As big as that country is, I could see why they'd need them. Anyone ever heard them? I may have read about that here,   http://www.alfalima.net/
