Amateur Radio / Re: 2M SSB - Is it worth the cost?
« on: June 02, 2021, 1552 UTC »
Hey All.

I guess I'll chime in. 2M SSB was a LOT of fun. But even  "back in the day" it was  never very active compared to FM. Maybe a net or two and a bit of  other traffic  in the evenings. On    FM you had a long wait to get in on a number of frequencies

A decent 2M SSB station  could work from here in Boston to NYC most every night, without enhanced conditions.

I have been off 2 M (FM and SSB) for a LONG time now. But even FM seems pretty dead. A few years back while in NYC (!!) on a Friday night I scanned FM and found near zero.

One of the biggest factors of course , is the antenna / height and to a lesser extent , the power level.

A 2m SSB signal needs to travel unimpeded in order to go into "development". Clearing local  obstacles (immediate trees/ structures) is really desirable. Clearing  the more distant terrain is good too. The closer and higher the hills, especially in the wrong direction, can cause a radio shadow.

So  2M SSB  ,being essentially aimed 90 deg. toward the horizon requires decent clearance.6 M being  a SKY wave (at WHATEVER take off angle) still requires some height, but may be less fussy if all things are "equalized" re 2M physics vs. 6 M physics.

In flat  Florida, height   really shouldn't be as   big  an issue as it was in the hilly Northeast.   Just clearing the trees and local blockages ie large / close buildings may cut it.

My REAL concern is activity. Outside of Field day and the scheduled VHF contests  I am not sure how much would be left. Even DURING those events, I may think activity may be kind of thin.But I have been off for so long I wouldn't want to say for sure.

FWIW, 900 Mhz amateur radio  debacle  here  went from ZERO, to very active (with a number of VERY BIG mountaintop /skyscraper  repeaters) to ZERO,dead, buried in 10 months or so (!).

 Even the guys that built the repeaters bailed out.I LOVED using it ( I had   some bullet proof  Moto  HT and mobile gear, a  big  commercial fractal  panel antenna and  lots of home brew antennas) when it was active, but it didn't last :'(. Kind of an exceptionally sped up version of the 2 M band story - up, big, down , "dead".

Is it "worth it" to put up a station that may give great sanctification and fun, but for only a few days a year ? Only you can answer that. I'd HATE to discourage anyone from using any band.

I am not longer able to put antennas on my large flat apt building roof. But a few years ago I DID have a small "farm" up there .I had nothing for 2 M SSB- to me it was  not active enough to justify using the mast  space ,I put up a "more" active 6 M band  antenna instead .You may not have this problem

 I didn't invest 6 M  very heavily either. But 6 is a much better "value" , at least to me. I had a dipole and used barefoot power
of around 15 watts on peak. I had a blast, but only on 6 or 10 days a year when things were open strong enough for my tiny flea station  to be able to work.Also I used to hear a LOT  more  (and also more often) than I could actually  work.Just LISTENING on 6 was a GAS.

  6 is skywave, while 2 is tropo/scatter etc. I  got a FAR larger coverage area on 6 (ie Portugal,most of US), even if it was on  a "10 day a year"  small station."   It seemed the better way to go, at least for me at that time. Your mileage may vary.

IF I COULD (which I CAN'T) I would build  a "better"   6M station with a GOOD  antenna and decent power. I  still wouldn't go TOO nuts ( on something that may now  work TWENTY days  per year , rather than ten :))). But I would definitely go a bit bigger that what I had  before, IF  I could do it again.

I LOVED studying the propagation on 2M  and did a LOT of QRP on SSB and horizontal  FM.

And now , the " Complaint Dept."- I am a rag chewer. A quick signal report on 20, 15, 12,  10 (or 6 or 2) is GREAT. AWESOME ,I just "worked" India (or wherever) . Now what ? I really didn't get to know the person and may never "work" him again.

DX on 6 (or 2) is a REAL TREAT and a really big , fun accomplishment. But when Dx is in, no one wants to talk very long , they want to move on and fill the log. And while I really "get it" as being a lot of  fun for SOME folks (more power to 'em ! ),   I  didn't want to be  just a "log filler", even on rare dx . Especially to areas that I had already worked once or twice before ,over any period of time.

That's why I loved 40 NVIS.With  7 watts on peak and  a low dipole it was almost  like making a dependable "phone call" EVERY day / 365 per year to the same folks at 100 to 200 miles.I REALLY got to know them, which for me was much more fun than just  giving /getting   a 5/9 report.

I never was into digital QSO modes.

I liked to put up beacons at my QTH.

Hey Poacher,

I have been a bit intrigued by these ones,which have seen  on the frq. list.

Maybe  when my new BCB Dx  antenna is finished.

Hey All,
 
I recently picked up a beautiful 1920's variable cap mounted in a heavy oak side sloped enclosure. The cap , dial and panel look almost like new.

The downside was that it  only topped out at 250 Pf , not really high enough for any of    my "serious" uses. The  inductor for the bottom of B'cast  is 400 uH (!) of #28 rectangular five point spiderweb.It looks more like a SAILBOAT than a spider's web :). Space was extremely tight. It's  wound   on a small sheet of vanished writing pad  thin  cardboard. Basically I "tried" to violate EVERY rule of good crystal set building (re L/C ratio, coil shape,  coil form material ,  var cap insulation being  bakelite, etc, etc).

I may try a few outboard tricks to "sort of" help it, but don't expect too much other than locals here.

But it WILL be a NICE piece of "eye candy" with nickel binding posts, cotton wire, etc ,etc. Everything is being  done with  1920's material and look.

My bedside shelving is small and already mostly packed up with gear , but this rig will be small   and should fit .  I'm thinking of a  fun little single dial radio for the local  big guns on an indoor short wire, which is fine.

Years ago I smelted my own "home brew" lead  sulphide material by melting lead and rapidly working in  raw sulfur. It  instantly burst into flames and had to be blown out like a big birthday candle.The  resulting material was black and ugly- NOT pretty and  sparkly like   the silver bearing "steel" galena " that I've also  used   . But BOY, was it HOT- very sensitive and easy to set . Maybe I try  whipping up another   batch  in a small metal cup  for use on this set.

Hey Poacher,

 Very in interesting info especially re SLFCS (which I had not heard of  ) and GWEN which I had heard of and remember when IT was up.

A bit OT , but FWIW, I was assigned to the CSS in Germany, not DIRECTLY involved in SIGINT, but as a support of it.

But there was plenty of "side action". For reasons I do still do not understand , I was allowed to build  my own personal listening post IN the barracks. It included outdoor smaller U/VHF AM/FM, a large  (successful)  "trans Atlantic" VHF low band antenna and HF antennas (on R-71a , R-70 ,etc). It was amazing how much "open mode" traffic there was  - IF you knew where to look.

I was ALSO allowed to do the SAME thing  in the barracks  while at a previous posting in SC ( 100 ft long wire with Rhombic  antennas suspended underneath- for U/VHF/AM FM  "SIGINT" and TV Dx), mostly using the same rigs as above.I was actually able to locate  an intelligence "entity" close by  on my installation that was still using CW ! That's ONE way to "hide"   (I guess ???).

During exercises in SC I   used to set up a hidden UHF aero receiver at work  on our local tower UHF  frequency listening for "hostile" call signs on approach. I'd quietly don my gas mask a full minute before the "surprise" attack. Folks never figured out how I did it :).

All happened a million years ago, I imagine things are different now.

Hey Syfr,

The tower / building that now transmits JIB has been on the air under various call signs ( that went broke) for many years before Bob bought it.

I think having the personal resources to keep her on air is the main reason why it has lasted.

Now that he has a following it seems that his annual fund raising is enough to keep WJIB, net control WJTO ( Maine) and the smaller outlets on air.

FWIW, the original JIB call sign here in Boston was a “beautiful music “ big signal FM operation that eventually tanked and got sold off to a new owner and a new format.It had no connection to Bob at all.

Hey All,

 Ray : DDR design is  interesting , never seen that one.

Dood: I have seen train antennas like that.

Still learning.

Longwave Loggings / Re: 338 UMP
« on: May 26, 2021, 2159 UTC »
Hey Pinto,

I once got frost bite on my ear going for SAQ at Marconi Beach Cape Cod (which I DIDN'T  copy, but DID copy on another "warmer" attempt). Used an   R-70 with 2000 ft on gnd, 500 bare copper in salt water. Rig would  completely fail from such super cold and had to be warmed up by running  car heat to get it to work again. No permanent damage caused, just too cold to work.

I'm not that crazy anymore :P

Hey Pinto.

Yes, it’s possible when one goes off , another could be copied.

Back in the day I logged beacons from the   Eastern  1/2 to 2/3 of the US (and Canada) .

Some of my favorites were the ones jammed up near the bottom of the B'cast band ie bcn YWA, etc.

It’s kind of like LW broadcasting- log it before it goes extinct.

I used to like to dx the old Frying Pan Shoal bcn off shore SC  and the Super Power TUK Beacon with aviation voice weather at the Loran sight on Nantucket , both are long since QRT.

I know of at least one guy who built a LW crystal set in MD and got quite a bit of Beacon dx.

Eventually I am probably going to  build some type of LW loop (  unsure of size yet)  for the ATS 803.I will have to get away from local noise though.

Propagation / Re: E Season
« on: May 21, 2021, 2243 UTC »
Hey All,

 No Es dice here but got something lower down that I've tried to get for YEARS. Please see my post in  the MW section.

Tried ATS 803a with 20 vertical in park across from apt. Highest frq copied was loud data in QSB on 17085. That is were I maxed out. Not a PEEP above that.One E skip map showed a weak opening from NC over my QTH to Nova Scotia. Later on I saw Dx maps seeming to show a better situation with some fairly long  openings on 10 and 6. Maybe they were weak signals   but to well equipped  stations.My set up was kind of crumby, but if opening was big, I would THINK I would have copied something .Not a biggie though. I got some HF time in, something I haven't done in a LONG time.Overall, a "good" session on HF and  awesome on MW. 

Quick log :2030 UTC -Nothing in 16 MB B'cast. No signal on  15 WWV, 15035 Gander Radio Wx good, but  only 3 broadcasts in 19 M. 20 M copied NE US only.40 M  CW was HOT, copied only NE US on voice. QSO's complain of noise and QSB on what I would think should have been more stable possibly NVIS paths. Overall things good but short and wobbly.

Hey Syrf,

Yes, it was fun to mess around with.

I am really liking the SR-1. I bought it recently as a package deal along with a Select-A Tenna for fifty clams , which was a very good deal. I had one many many years ago , can’t recall whether it broke or if I sold it.

I know some people who have been on air at JIB. A few “ interesting “ things have happened over there.The owner, Bob , is an absolute sweetheart. He ran several stations commercial free out of his own pocket ($$$$! !!!) for many years but now does a fund raiser to cover his cost.He has also saved a number of small AM stations from going off the air, one recently on Cape Cod. In total he has maybe 8 AM and some FM translators around our region, mostly in more Northern New England.

The master control for the network is at WJTO 730 in Bath , Maine. The 223 ft JTO / FM translator tower is located behind his home.

Hey All.

I figured I’d chime in.

IMHO , when most people think “Solar Cycle “ it seems that the emphasis is on HF.

To me HF in 2021 seems to require a better home station than what you could “ get away with “ 25 or 35 years ago.

There has been a reduction of stations, especially outside of the ham bands and overall, the past cycles have been just “OK “.

At least for me , with all roof top antennas long gone AND all the RF noise in the apt.I am pretty much toast re weak HF. FWIW , AM BCB ain’t such a big bargain either and also requires a decent signal to work .But at least it’s  easier to null noise.Plus if I give up BCB (or occasional stronger HF ) in the apt., I’ve pretty much given up on “in home”radio ,which I refuse to do.

The only way I can really hear anything weak ,on any frequency ,is to set up away from my apt.As I grow older and times have changed, I am somewhat less inclined to attract attention to myself by setting up remotely.Especially late at night .

All this being said, even IF a cycle is overall mediocre, it STILL can have some real “ up” times as well . You just really have to be on top of your game more.

There are modes that are not fully (or at all) cycle dependent ie trans equatorial, gray line, E ,sporadic E cloud, tropo for VHF and up,etc.One could research these as a way around the long haul F modes (F1, F1.5? F2, F3 ?)


But I still will drift out at times , especially  to work AM BCB which is a lot more "subtle" than a big HF antenna and might not be as much “ cycle affected” either .On vacation, at a location that I PAY for , HF would be  more in the mix.

Equipment / Dueling Selecta- A Tennas (NOT Banjos)
« on: May 19, 2021, 1259 UTC »
Hey All,

Last night I decided to try out something that I had seen that originally used two  stand alone large/outboard  home brew ferrite bar/ tank "antennas" for Co Channel "pest control" application .

The idea was to  fully null the pest with the receiver's ferrite first.Then place one outboard  bar to boost the desired station  coupling it  along SIDE of the  rig's internal  ferrite and the other outboard bar off the END of the rig's ferrite to deepen the pest's null.

Since I don't have any  big  ferrite, I decided to try two basic/no jack  model Select- A -Tennas instead. The results  were intriguing.

I tuned into "My favorite Co Channel " (starring Ray Walston and Bill Bixby :))) 740 for  CFZM  vs very  local  WJIB which was still huge at 5 watts night power.

The expected orientation did not pan out at all, at least on the Super Radio I and these air core loops.. Trying to deepen JIB's attenuation by aligning one of the loops null to the rig ferrite null did nada, at least for me in this case. Changing the distance , etc, didn't work at all. All  action was  attained  by coupling both loops peaks "broadside" to the ferrite.

Odd, since  loop peaks are  much more "vague" than the "black hole "  of the  null  (after fifty years of playing around I am STILL amazed by radio !).

The best configuration seemed to be having one loop at one end of the ferrite and the other at the opposite end and on the opposite side of the radio cabinet. That way both loops "boosted" the SR-1 for Zoomer but had as much physical separation as possible.The only null action was in the  radio's  ferrite.

Even MORE wacky was that loop closer to JIB loop "liked"  a more  "conventional" 90 degree coupling angle, yet the other one ""needed" to be at 45 degrees in order for the entire set up to work. And of course like  previous single loop  experiments, all placements (rig, loop 1 and loop 2) HAD to be exact to within 1/8 to 1/4 ". If any parameter was off, even a tiny bit, you heard zilch (except a slight or moderate JIB artifact depending on what they were playing).

Zoomer rolled up and down (as usual), but never really came up to much  beyond weak or a bit better , even after a while of being parked on frequency. Zoomer's transmitter  antenna  null is in my direction (not   "optimal"), and also  propagation  seemed kind of  crumby as well.

I  repeatedly tried it "barefoot" , going over to  only the JIB closer loop  during these marginal conditions. No dice.Every time I tried.But when the second loop was brought back in, Zoomer came back in (WHEN the  QSB "cooperated").

So the takeaway ,at least to me under these conditions and set up , is that the second loop  WAS useful, even in this situation of two stations nearly 180 off from each other (which is a "challenge").

The next target is 650 with regional WSRO vs THE LEGEND (WSM). Both are  ALMOST in the SAME direction from me. If I can tame SRO even a tiny bit and  bring SM up a TAD , I'll call it a big victory. "We'll see".

BTW, I  really miss my MFJ 1026 :-[.

Your mileage may vary on all of this  and no warranty is implied :).

Hey All,

Thanks  for the responses.

NJQA: I had heard about vertically buried / explosive charge activated  "Pop Up " antennas  underneath pineapple field(s) in Hawaii used at "certain facilities "  . Details unknown.

Hey Dood,

VERY interesting re TIS and part 15 installations.

I too have heard some of these at amazing distances.The X band especially can be very kind at times.

But you don’t hear much ( or anything) about commercial music/talk stations that are really limited on what they are allowed to build.

Just curious about what those guys have
run into.
