MW Loggings / Re: Not hearing Hudson Valley TIS lately 1710kHz.
« on: July 19, 2021, 1403 UTC »
Hey All.

Yes ,1710 Kc is probably the “ best” place to “play” due to it using short antennas.

But at least here, the X band has enough
open frequencies close to 1710 that it doesn’t matter.So I can QSY without any noticeable issues.

I DO have a 1 MC crystal  that is almost the size of a pack of Marlboros :)) .It’s another story completely.

But frankly , now my AM tx “goals “are to only cover maybe 200 ft East and also from my basement shop to the 2nd floor shack.Should be “ easy “ ( when I get to it - LOTS on the bench right now and only limited time to work on stuff.).

Hey Chris,

Good to see a "neighbor" in here.

Elsa was kind of a bust, but that's OK.  Quabbin Reservoir (Boston's water  supply) approaching /or at 100% capacity, which I believe is  a 2 year supply.

We now need Sun for my garden , we are good for now on water.

Hey All,

Elsa summary here : Not too bad-Gust 67 Cape Cod, almost NO wind at Boston, gust 25 (maybe). Some isolated boats pulled  off moorings /run  aground.

Rain : Only 2" here in the city, but nearby Wellesly had  4.47".

Boston from   the 1st to the 10th July had 7.9 " of rain.

Still "taking on" water here , but not "disappointed" by Elsa's low rainfall total either. We  now need Sun    and more water later (which we may get this week).

At end of storm , vivid deep blue  clearing line pushed up from the SW. Low clouds cruising right along, mid / high clouds had  little movement.Interesting.

 Entire storm edge visible when started to clear- Dark precipitation clouds to North, deep blue to SW.Nice.

Hey Pinto and All,

Before dawn we started get into Elsa’s
rain shield.Only light rain so far.

Expecting 2-3 “ rain ,” some” wind here at Boston.

Isolated tornadoes seem to have already occurred in  NJ- gust 78 -from “nearby”twister ? Possibility  of tornadoes  Long Island, CT, RI and into SE MA later today.

No severe issues for Boston yet. We may be too far NW of track , but I will keep checking NWS web site during AM for updates.

MW Loggings / BCB Black Out
« on: July 08, 2021, 1659 UTC »
Hey All.

 During last night's  severe storms,  the AM BCB was wiped out here.

And I don't mean by static crashes, even though there were zillions of those.

The afternoon and evening  BC  band was just simply wiped dead. NO "expected" day time New Yorkers copied.  ALL  of  the normally  "definite" big night time  NYC stations either  didn't show or were still  terrible, LONG after dark.

 ALL Regional stations  evaporated.

Again many crashes, but you could still tell  that there was almost NO propagation from anyone.Also  my local noise didn't help.

Bad.

The good thing about a completely indoor system is that you notice band changes more .My system    is more "marginalized" .Therefore it is somewhat more  "on the edge" and will crash down  sooner than   a nice  outdoor antenna would. I work  deal with captures much less than 10% of  what   an outdoor antenna would grab. But I do get an easy directional  null of some noise sources. Sometimes , the strongest loop orientation isn't necessarily the best . I swing the rig's direction first and bring in loop to least noise / but still with some signal.Cleaner but quieter.

Didn't try Zoomer 740 but  line  of  sight  local WJIB 740 was excellent on it's loop heading.I also copied Big signal /Big band WSRO 650 which also had no bad signal effects from poor band  conditions. Both are honkin' ground waves and stayed ultra clean , no real static  crashes heard on carrier  when audio went  quiet.

Hey Pinto, All.

More rounds of heavy Thunderstorms yesterday.1000+ bolts / hr in area.

Heavy rain , 3/4” w/ some very small very close but not very loud strikes.

3 strikes within 500 ft or less to East.

Could see pale Peach Orange bolt, not overly bright.
Low amperage /“sort of high” voltage ?

Instant high pitch crack of respectable but not overly loud thunder. Like fireworks ,not thunder explosions.

This happened 3 times close to me and a few more maybe 1/3 to 1/2 mile.

Fast moving, edge of severe cell , but only weak strikes, moderate to heavy rain and maybe gust 40.Biblical looking though.

I have seen ultra weak in cloud lightning strikes during snow.Each next one failed worse, last one was just   light ,no thunder

Snow lightning is like no other.

Add : 7/7/21  2100 UTC .This time they used the "real" stuff. A number of local strikes, LOUD, but nothing like the "artillery barrage" in the heavier part of the cell. They were getting popped every 15 or 20 seconds.Fairly loud, but  low frequency  sounding , most seemed   powerful and  mean  ground  strikes 4 Miles south.Close miss. Yesterday the sky turned  green for the second time this year.We only got "some"  lightning (1 per minute ?). But kind of intense , with some strikes within 500 ft.Heavy rain also.

This morning 7/8/21 0800 UTC. More  storms at predawn  . A few strikes  not super close.With a  lot of  Cloud to Cloud lightning.Noted best was bright white horizontal bolt 10 Miles long?). Also had other spectacular in cloud strikes.

We got heavy rain , some lightning here.Most action 4 or 6 miles to North. Again ,like yesterday, close enough to really   see it well , but not on top of me  either.I'm OK with that.

Now close pass by Elsa.

More rain . FILL that reservoir :).

Longwave Loggings / VLF Lighting Direction Finding
« on: July 07, 2021, 1916 UTC »
Hey All,

DF of Dx storms 90 to 120 Mi to my West yesterday PM.

150 Kc somewhat weaker than higher up checks.Kind of a surprise.

Best was around 230 or 250 Kc , also ripping loud  at 520 Kc.

Things seemed to have rolled up or down in signal strength as one rolled 250 to 520 Kc.

Nice to near zero nulls on S  803a rig, gave a decent bearing to storm cluster.

I am working on other LF projects too.

Hey Rob. 

Brazil allows some crazy power, one  station at  250 kw , a good number at 100 kw.

FWIW, Years  ago  I  BRIEFLY copied  a very probable Brazilian on AM b'cast   (up- for only 30  seconds good , then down and  gone for good  )   in MO on a  8 ft    loop crystal set.

SOME REAL JUICE  !

Not sure what the Brazilian flame throwers  will do during all this,

Hey Pinto.

Rounds  of  thunderstorms lately , some severe .

6-30-21 : PM   100 degrees, then absolute monster Cumulonimbus w/huge vicious  anvils and  high winds. Sky turned green just to our South.Outflow winds higher than seen  here in quite a while. 
Up to 300 + flashes every 10 minutes in area .  Thunderstorm outflow   downdraft wind   boundary, well outside /ahead from precip area  was  visible on Radar,  length 25 + mi long .

Second 6-30-21 round of thunderstorms after dark, much lightning,  and much more rain than earlier severe event. I caught some nice high altitude lighting on video.

Copious rains lately- cumulative,since Wed,  3 " + in gauge . Some "training" /"conveyor belt"  precip events  lasting all night.

7/3/21: PM was VERY heavy , almost torrential ,  rain with occasional lightning,  then an hour or so  break of only light  rain , then  just "heavy" rain  with  a  few more bolts. Yet the closest SURFACE feature was  150 + miles to South. Stuff apparently happening upstairs. Cool (to almost   COLD)  for July.

Wild , you gotta love New England

I am still welcoming  ALL the water we get though. Still a blessing, No "excess" yet.

Hey Boombox,

Great to see your comments.
I hope it all works out for Brazil.

OT, I see you have  a “TRF” rig on your equipment list. Is it home brew ? Any details.

I have a few projects on the bench, a TRF included.

Hey All,

I was aware that Japan 's FM band went down to 76 Mhz.It apparently worked out for the Japanese a lot of years ago."More power to the Japan", but things are a lot  different now compared to when  they  extended FM.

I am not really sure what is fueling the Brazilian extension though. Is it  mostly low power translators ?? Is there THAT much of   a long term future market in 1930's style/ over the air/ 76 Mhz  FM  analog  technology ?

Isn't the REAL lucrative (greedy) future on 800 or 900   (or higher) Mhz)  (or fiber optic) were folks are  forced to PAY for it ?

Will this new FM band  be like our local  WMEX  1510- "ME TV  Radio"  (run by Me TV) ? 'MEX  is  LITERALLY  3 minutes or more  of  the same repeating commercials all about "Me" Tv shows (What time  Gilligan's Island  is on , etc)    grudgingly  punctuated  by   maybe 2 minutes of   music. PURE TORTURE.

I am going to wire  FIVE 1510 Kc  traps in series so that I NEVER even  have to  hear two seconds of it  as I quickly tune by  :).

(OT-WMEX was once an early and very  influential  rock station. "How the mighty hath fallen". The "Me Tv" folks have soiled  this call sign .The FCC should  retire WMEX, and give them something like WBAD instead . Nauseating stuff.I'd rather listen to 12 straight hours of my local TIS. I hope Brazil doesn't  wind up with content like this).

Don't get me wrong, I am in favor of ALL broadcasting if , in  my opinion, it is "useful" or desired by the general public. If Brazil can actually get more listeners onto conventional FM , great.Is there a lot of public "enthusiasm" for this move ? I HOPE so, but don't know for sure.

OR is this a "push" from the Brazilian   broadcast business without a huge actual  need ? I am not sure either way (and probably shouldn't guess) whether this actually good for or  really desired by  the Brazilian PEOPLE (or not) . I'd need more info.

A band extension is a rather straightforward event with little in the way of new technology required, other than buying  an extended receiver.

I have heard that Brazil is also home to a LOT of FM pirates. Is this just going to make more room for them ?

I am just  a bit gun shy from past experiences  about who really wants these things, that's all.

Remember the AM stereo systems ( PLURAL), IBOC, shortwave DRM,digital TV and maybe another 1 or 2 other
"misguided" technologies that were "solutions in search of a  problem" or simply just  NOT  desired by the general public.

The Brazilian extension may not fall into this category, but....

Just sayin'.

MW Loggings / South Boston , MA Dxpedition
« on: June 27, 2021, 1452 UTC »
Hey All,

6/27/21 1400 UTC -South Boston , MA. Open salt water  for around 2 miles to the SW , then land and eventually to  hilly terrain ( 300 to 600 ASL) at around 10 mi to  SW.

570 WMCA weak, but sort of usable

1010 WINS absolutely nothing, a big surprise since 'INS "usually" does better than 'MCA

1620 pirate , good copy ( see Free Radio section)

 OT, FWIW, this is a KILLER spot for 10 M mobile dx.

Hey All,

 6/27/21 1400 UTC .I logged the same Haitian station  described  in my earlier  post.

Quite good  car radio  at South Boston, MA/ seaside , very gradually degraded as I traveled toward my home QTH.

When we got close,it completely went  away.

MW Loggings / Re: Anyone Else Have Signals Down, Noise Up ?
« on: June 25, 2021, 2144 UTC »
Hey Pinto,

SO true. Even my Windsor “ Boys”  2 transistor reflex would grab stations like WBT from NH at night. Not much audio ,but “ there”.

 Things up  a "bit" 6/25/21 0300 UTC. A little bit of Zoomer audio for the first time in well over a month, but very badly chopped up in the "competitive"  mixing/beat  flutter w/WJIB. Their Harris transmitter was apparently pulled out and programming is now going out over their new French transmitter  manufactured  by Cuisinart   ::). A  few songs recognized but overall poor copy.

1690 WPTX  MD up good at times in QSB .
1700 WRCR NYC poor ( go figure)
1720  Station ZZZZ ,strong copy (fell asleep with phones on  :)))

Earlier in the day  : 2200 UTC on  the car radio 6 miles West and then Southbound on  the big highway-  1010 WINS actually usable (!)  with  weak to fair signal  but acceptable  audio.

My other NYC  "weak test station " 570 WMCA was a much tougher catch. But even they eventually came up some when   out on the open highway .   Weak  to only occasionally fair. Sort of usable,but not very good.

So they takeaway is that my QTH may also be a factor re the weak New Yorkers.

Hmmmmmm.

OT, also "Dx" tested 101.3 W267CE /JIB translator while on highway to South . Fair /poor.  Chopped up (and  fully captured  at times) by another regional station on frq.

Hey Treehouse,

 It's really good to get a far  West  coast response.

Yet another post that reinforces the idea that "it ain't just me" :).

I am taking this "opportunity" to do hyper weak signal work .I am making  notes how/when super weak ground wave  starts change from "daytime" mode  to  high angle sky wave near and after sunset.

Just for grins, the other afternoon /evening I was using   a pocket transistor radio to "borrow" the 455 KC  Intermediate Frequency   offset emission. It  provided  the  beat  source to my Dx rig.

I could have also dragged out the signal generator to do this, but I was simply fooling around with a different   unmodulated carrier signal source.  Interesting on how strong a beat note can be  and yet still have NO trace of audio. It also demonstrated the stability of the pocket rig, which was "fair".

So , I am STILL working AM BCB ,despite it being in the mud right now.
